1. GENERAL
The SL 1000 Compact multicom system is an advanced multipurpose intercom system with a maximum
size of 32 terminals and with 3 two-way speech channels and 1 one-way music channel. In addition to
handling the speech communication between any two user terminals, the system can transmit numeric
messages from one terminal to another, using the 4-digit display unit which some of the terminal models
have. The display unit tells which terminal number you are in contact with, the time of the day, stored call
requests and programmed information codes, which, for instance, tell the expected time of return or the
reason for absence. Thanks to the possibility of storing information codes and leaving call requests, the
system serves the user also in cases where the normal telephone or a standard intercom do not, that is
when the person sought for is busy or not present. Because the probability for this can be very high, in
certain types of organizations even 70 %, the SL 1000 Compact system increases the efficiency of your
work and gives you more undisturbed working time than any traditional system.
The SL 1000 Compact system replaces, as it is, partly or in whole several such systems that usually are
bought separately, fir instance messenger call systems, nurse call systems, gate/door station systems,
absence registration systems, public address (PA)/program distribution systems and audible paging
systems with answer back possibility. Using the serial communication card of the system a peripheral
device such as a monitor or a printer can be connected, or the system can be coupled to another system,
such as a wireless paging system or a system for flexible working time registration. A relay can also be
used to control e.g. video cameras or electrical door locks, and in this way a more efficient integrated total
solution can be found to fulfill the internal communication and surveillance needs of most organizations.
The heart of the SL 1000 Compact system is a fully electronic microprocessor controlled central unit. The
system functions are based on a program stored into the memory of the central, so the modifying of the
functions or the adding of some special features do not usually require any additional electronics, but only
the exchanging of the memory chips. Only the relay functions and the serial communication to a peripheral
device or another system need additional cards. In addition to those there is a real time clock card, with
the help of which the system clock keeps the time also during power breaks, which the standard clock
does not.
A big number of special functions and features are included in the standard program, such as free
numbering of the terminals, determining the members of the group calls, giving the priority right to desired
terminals, and defining of blockings, i.e. which terminal are not allowed to call certain other terminals.
These can all be defined or connected on or off at the customer's and even by the customer. This user
programming does not require any special equipment but is done using a normal desk terminal of the
system, which for the duration of the programming session is connected to the programming connector of
the central. All programming performed is stored into non-volatile memory, which retains its contents even
during power breaks. The user programmability of the SL 1000 Compact system makes it very flexible
and modifiable according to the needs of the customer.

2.1.2 GENERAL
The central unit of the SL 1000 Compact system is intended for wall-mounting and is 275 mm high, 520
mm wide and 110 mm deep. The cover of the central cabinet is removable, and the mounting plate
fastened to the back side of the cabinet holds a power supply unit (PSU) at the left end and the processor
cards (PRO-C), which also functions as the back board but or mother board for the connection cards (CC-
4), see figure 2.
The central can have 1-8 connection cards installed, and as to each of these up to 4 terminals can be
connected, the maximum size of the Compact system is 32 terminals. A radio unit or some other type of
program source can be connected to one or several connection numbers via a special interface unit, in
which case the maximum number of terminals is decreased.
The central has 3 two-way speech channels, so 6 terminals can simultaneously communicate with each
other pairwise. Additionally there is one one-way channel, which can be used as a listening channel for a
radio or some other program source. All terminals in the system can be listening to this program channel
at the same time. If 2 or 3 program sources are included in the system, the number of speech channels
drops to 2.
The central is fully electronic and the speech connections are based on an analog matrix controlled by the
processor. The signalling, or data transmission, between the processor and the terminals is handled via a
current loop. The signalling includes reading the buttons depressed as the terminals, turning the LEDs of
the terminals on and off, and sending numbers to the display of the terminals.
Three types of optional cards can be installed into the central besides the connection cards for the
terminals: A real time clock card (RTC) with battery back-up, which keeps the system clock running during
power breaks, a serial communication card (SCC), which is needed for controlling a CRT-terminal or a
printer, or when the Compact system is connected to some other type of system, and a relay card (RC-4)
with 4 relays, which can be used to control e.g. CCTV cameras or electrical door locks. If more than one
optional card (OPT BUS) is additionally needed, which extends the bus for the optional cards, so that all 3
optional cards can be connected.
The Compact system will, after connecting power on for the first time, function in its basic mode, without
the customer having to do anything else than setting the time of day to the system clock. The connection
numbers for the terminals are then 10-41. The numbers can, however, be freely programmed to be in one
of the ranges 00-99, 000-999 or 0000-9999. A lot of other special features and functions can also be
programmed by the user, such as group calls, call blockings, priority rights, relay controls, etc. All these
user programmings, as well as the short code numbers, transfer addresses, call request numbers,
information codes and alarm time settings if the individual terminals, are stored in the non-volatile
EEPROM memory of the processor card, so they are retained also past power breaks.

SL1000 Compact, System manual 7(57)
2.1.3 THE STANDARD PARTS OF THE CENTRAL
The functional standard parts of the central are the power supply unit, the processor card and the
connection cards for four terminals.
2.1.3.1 THE POWER SUPPLY UNIT PSU
The power supply unit, which is built into the central cabinet, consist of a mains inlet connector, a mains
transformer, a rectifying/prefiltering card and a regulating/postfiltering part.
The mains inlet socket is on the left and side plate of the cabinet. The two primary fuses are located inside
the socket, so the replacement of the fuses can take place without removing the cover of the cabinet. The
fuse type is T2A with a mains voltage of 110 V AC, T1A with a mains voltage of 220 V AC or 240 V AC.
The mains transformer located in the upper left corner of the cabinet is constructed to accept 110, 220 or
240 V AC at 50/60 Hz. The mains input voltage is selected with soldered jumpers at the primary winding.
Below the transformer the power supply unit card (PSU-C) is located. It includes the rectifiers, the filtering
capacitors and the two secondary fuses of type T1,6A. The card is fastened to the mounting plate of the
cabinet with the bolts of the two filtering capacitors. The output voltages of the card are +30 V, +10 V and -
10 V, which together with the ground voltage are passed to the processor card via a 4-pin connector for
regulation and postfiltering.
The left upper corner of the processor card holds the remaining part of the power supply unit. In this part
the -30 V voltage is stabilized for the use as supply voltage for the terminals. The +21 V needed as
programming voltage for the EEPROM and the +7,5 V needed as reference voltage on the connection
cards are also made from the +30 V. The +5 V and -5 V needed by the logic and analog circuitry are
regulated from the +10 V and -10 V.
The +5 V and -5 V regulators (7805 and 7905) and the stabilizing transistor (TIP 121) for the +30 V are
mounted on the cooling profile. The postfiltering capacitors are located below and to the right of the
profile. The components for generating the voltages +21 V and +7,5 V, including the trimming
potentiometer for the +21 V, can be found above the connectors for the two first connection cards. Below
the cooling profile there are three LED indicators, from which the presence of the voltages -30 V, +5 V and
-5 V can be checked.

2.1.3.2 THE PROCESSOR CARD PRO-C
The processor card also functions as the back board or mother board for the connection cards, so it is
equipped with eight 32-pin connectors, on the connection card bus. In the lower left corner of the
processor card there is an additional 32-pin connector of a shorter type for the connection of the optional
cards. There is also a 4-pin connector marked "DESIGN", to which a standard desk terminal with display
can be connected for the user programming of the system.
The processor circuitry consists of the CPU (microprocessor 8085A), EPROM program memory (two
chips, one type 27128 or 27256, one type of 2764 or 27128, so the program memory size is 8-48 kbytes),
RAM data memory (TC 5564 or 5565 of 8 kbytes), non-volatile EEPROM data memory (2817 or 2817A of
2 kbytes), the I/O and timer circuit (8155), and the discrete components.
Three of the components are adjustable: two trimming potentiometers for adjusting the RESET and TRAP
levels of the CPU and one trimming capacitor for adjusting the 2 MHz clock frequency. These are all
adjusted at the factory and need normally not to be touched.
The program is automatically started when power is connected to the central. With the RESET button on
the processor card the program can be started from the beginning if needed. The RESET LED is lit when
the CPU is in the RESET state.
All data transmission from the processor to the user terminals and vice versa goes via the I/O interface
circuit 8155 and the connection cards. The processor keeps scanning the terminals to read the keys
depressed, and sends data to the 4 LEDs and the 4-digit numeric display of the terminals. The control of
the analog connection matrix on the connection cards is also handled by the processor via the 8155. The
state of the switches in the matrix determine which terminals are in speech connection with each other
and in which speech channel..
2.1.3.3 THE CONNECTION CARD CC-4 FOR THE TERMINALS
On the processor back board card there are connectors for 1-8 connection cards (CC-4, Connection
Card), to each of which 4 user terminals can be connected, the maximum capacity of the Compact central
thus being 32 terminals.
Instead of any terminal one can connect a program source (radio, tape recorder, etc.) via an AIC-unit
(Audio Input Connection Unit), or an amplifier with loudspeakers for announcement purposes via an AOC-
R-unit (Audio Output Connection Unit with Relay).
The terminals or the special audio interface units are connected to the connection cards using 4-pin
connectors, meaning that replacing a connection card or moving a terminal from one connection number
to another is very easy. The physical connection numbers, which also are the initial values of the calling
numbers for the terminals, are 10-41, but these can very easily be altered from the programming terminal.
All programmed terminal numbers must be of the same length, 2-, 3- or 4-digits long.
The functional parts of the connection card are the connection matrix, the interface circuitry for the
terminals, and the decoding logic. The connection matrix consists of 8 rows and a maximum of 64
columns (each connection cards adds 8 columns to the matrix). Each terminal needs 2 columns, one for
the incoming and one for the outgoing speech signal. The terminals are via the interface circuitry
connected to these two columns. One of the 8 rows is needed for the 488 Hz tone signal, from which the
call connection, alarm, busy, etc. tone signals are generated. Two rows are needed for one speech
channel, that is one row for each direction. Of the 7 rows left 3 two-way speech channels can thus be
formed. The remaining row can be used as a one-way listening channel for e.g. music. Each cross point
of the rows and columns of the matrix is a CMOS analog switch. The processor connects these switches
on and off via the decoding logic, thus determining which terminals are connected to which channels..
Each terminal is connected to the connection card with a 4-wire cable consisting of 2 twisted pairs, the
maximum length of which can be about 1 km. One twisted pair (A, B) is used for supplying power to the
terminal and for the speech signal going to the terminal, and the other pair (C, D) is for the speech signal
coming from the terminal and for the two-way signalling between the terminal and the central. The
interface circuitry on the connection card separates these signals from each other.

SL1000 Compact, System manual 10(57)
2.1.4 THE OPTIONAL PARTS OF THE CENTRAL
The optional parts of the central are the extension card for extending the bus for the optional cards, the
real time clock card, the relay card and the serial communication card.
2.1.4.1 THE EXTENSION CARD OPT BUS FOR THE OPTIONAL BUS
In the lower left corner of the processor card there is a 32-pin connector, to which one of the three optional
cards (the real time clock card, the relay card, the serial communication card) can be connected.
If more than one optional card is to be included in the central, one needs the bus extension card, to which
all three optional cards can be connected.
2.1.4.2 THE REAL TIME CLOCK RTC
The Compact system has as standard a software clock, the accuracy of which depends on the 2 MHz
clock frequency of the processor. The clock is running only as long as the mains voltage is connected; if a
mains break occurs the clock will be cleared and started from 00:00.
The real time clock card has its own battery back-up, so it will keep running also during power breaks,
which may be up to about two days long. The battery is, when needed, automatically recharged from the
+5 V voltage, the maximum charging time for an empty battery being some 15 hours.
The system automatically knows if the optional clock card is connected or not, and uses the software
clock if it isn't.
2.1.4.3 THE RELAY CARD RC-4
There are four relays on the relays card. Each relay has one potential free contact, which is normally
open. The maximum contact ratings with resistive loads are maximum voltage 48 V AC, 48 V DC,
maximum current 5 A (at 48 V AC or 24 V DC).
With the relay card the Compact central can control external devices, such as CCTV cameras, door locks,
etc.
2.1.4.4 THE SERIAL COMMUNICATION CARD SCC
The SCC (= Serial Communication Card) is an asynchronous serial communication interface of the
Compact central. The card includes both the RS 232C and 20 mA current loop connections with
selectable baud rates. The card is meant for two-way communication with other systems, CRT terminals,
printers and so on.
2.2 THE CABLE NETWORK
The cable network is a standard 4-wire star-configuration network of the same type as is used in all
telephone installations. Each user terminals is connected to the central with its own two-twisted pairs. The
cable type is e.g. MHS 1x4x0,5 or equivalent, where the wire diameter 0,5 mm means that the maximum
cable distance between the central and the terminals is about 1 km (3300 ft), based on a maximum loop
resistance of 200 ohm.
The star-wiring saves installation costs, because multicables containing several twisted pairs can be used
between the central and junction boxes located in different parts of the building. From the junction boxes
onwards 2-pair cabling is used for branching to the individual user terminals. Another advantage is, that
the Compact central can later be replaced with its big brother, the SL 1000 Mark II central, with a capacity
of 8-448 terminals compared with the capacity 4-32 terminals of the Compact central, without altering the
existing cable network, but only expanding it. The biggest advantage of a star-formed network over a ring
network is, however, that the malfunction of one user terminal or its cable does not prevent the rest of the
system from working.
The cabling is terminated at the user terminal end in the desk terminal cases with a 8-pin RJ-45 socket.
The wall terminals have a 4-pole screw connector for terminating the cable.

SL1000 Compact, System manual 11(57)
At the central the cables can be connected directly or via a junction box or some other form of
intermediate termination. Each 4-wire cable is terminated with a 4-pin screw connector, which then is
connected to its corresponding connector on the connection card. No separate cross-connection
arrangement is needed, because the screw connectors can easily be moved from one connection card to
another when e.g. two users are changing rooms between themselves, or in case of malfunction of a
single connection number on the card.
The former case can, however, alternatively be taken care of through user programming, since all
individual terminal features, including the number of the terminal, can be transferred to any connection
number.
The number of wires required does not depend on the terminal model or features; two pairs are always
enough. It is, however, a good habit to provide a little more wires than actually needed during the initial
installation, and thus preparing for possible wire damages and future expansions of the system. This extra
cabling represents a minor cost increase compared to the cost of adding cables later.
It is of major importance that the twisted pairs are used correctly, since connecting the pairs wrongly can
lead to overhearing of the calls or to bad functioning of the speech switching. One pair (A, B or 1, 2) is
used for powering the terminal and for feeding the speech signal from the central to the terminal. The
other pair (C, D or 3, 4) is used for feeding the speech signal from the terminal to the central and for the
two-way data transmission or signalling: From the terminal to the central the pressing of the keys are
transmitted, and from the central to the terminal the data for the numeric display and for the LED
indicators.
2.3 THE TERMINALS AND THE SPECIAL CONNECTION UNITS
2.3.1 GENERAL
The same types of user terminals and special connection units, which are connected to any connection
number of the central, are used in the SL 1000 Compact system as in the bigger SL 1000 Mark II system.
There are several terminal models for different purposes and environments.
There are two terminal models with display: the SL 1002 D and the SL 1002 DH which are desk top
models for office-type environments, the SL 1008 and the SL 1008 H which are indoor terminals for wall
mounting; the H-models have a handset. These models have an 18-key keyboard with 10 number and 8
function buttons, a 4-digit display, and 4 LED indicators, see figure 3 of the desk top model SL 1002 D.
Simpler terminal models, from which the display and part of the buttons and/or LEDs are missing, are the
desk top model SL 1001, the door terminal SL 1003 for wall mounting indoors and wall mounted terminals
for industry or outdoor use. Completely without buttons are the loudspeaker terminal SL 1011 intended for
announcement use and the passive subterminal SL 1013, which has both a loudspeaker and a
microphone.
The special connection units are the radio input unit SL 1000 AIC-L/D for connecting a program source to
the central, and the audio output unit SL 1000 AOC-RB with a relay for connecting to an amplifier with
loudspeakers.

2.3.2 THE TERMINAL MODELS
The desk top models SL 1001 and SL 1002 D are equipped with a two meter (approx. 7 ft) long
connection cable and a 8-pin RJ-45 plug. The wall mounted models have a 4-pole screw connector for the
connecting of the cable.
The speech connection between the user terminals is half duplex with automatic speech direction
switching. When both parties of the call are using a handset the connection is full duplex. The simplex
button, which some of the models have, can be used for manual control of the speech direction.
Figure 4 shows the block diagram of the terminal models which have the display unit. From the simpler
terminal models the display, the keyboard partly or wholly, and part of the LED indicators are missing.

2.3.3 THE SPECIAL CONNECTION UNITS
The audio input connection unit SL 1000 AIC-L/D and the audio output connection unit SL 1000 AOC-RB
can be connected to any connection number instead of a terminal.
The SL 1000 AIC-L/D
The SL 1000 AIC-L/D (Audio Input Connection Unit) is needed when a program source, such as a radio or
CD-player, is to be connected to the central.
The AIC-L/D unit is placed in a small box with the dimensions 150x80x50 mm (approximately 6x3x2
inches). Inside the box there are screw connectors for connecting to the Compact system and the
program source.
When the AIC-L/D is used the number of the central to which it is connected must be defined to be a
program source, see section 5.2.A and the programming instructions in chapter 6.
The SL 1000 AOC-RB
An external amplifier with loudspeakers can be connected to any connection number of the Compact
system for announcement purposes, with the help of the SL 1000 AOC-RB (Audio Output Connection unit
with Relay). By calling the assigned connection number from any user terminal of the system
announcements can be given.
The unit is placed in a small box with the dimensions 150x80x50 mm (approximately 6x3x2 inches). Inside
the box there are screw connectors for connecting to the Compact central, the amplifier, and the relay
contacts. The relay can be used for e.g. selecting the input to the amplifier, if the loudspeaker system is
used for background music between announcements.

3.1.2 INSTALLATION SCHEMES AND REQUIREMENTS
The SL 1000 Compact central can, thanks to its compact size (520 mm wide, 275 mm high, 110 mm
deep, and weight max 9,5 kg) and noiselessness, be mounted even on the wall of the office. It is, however
often better to place it in a room into which only authorized persons are allowed. The only requirements
are that there is sufficient air circulation through the central cabinet, that the relative humidity is in the
range 20-80 %, and that the ambient temperature preferably is between +15-25 °C (60-80 ºF).
The central will operate in the temperature range +0-45 °C 32-113 ºF), but big fluctuations in the
temperature or a constantly increased temperature will shorten equipment life time and lead to higher
service and maintenance costs..
The central cabinet consists of five parts; the mounting plate, the front cover, and the two end plates. All
the rest of the parts are fastened to the mounting plate, see figure 5.
The central cabinet is designed for horizontal wall mounting so that the mains connector is on the left and
the inlet for the cables from the terminals on the right. Then the air circulation through the power supply
part at the left end of the cabinet is as efficient as it can be. The ventilation holes at the upper land lower
left end of the cover are not to be covered.
If there is not room enough for a horizontal mounting of the central cabinet, it can be vertically mounted so
that the power supply and mains connector are pointing upwards, although this way of installation is not
recommended. In no case is it allowed to mount the central cabinet upside down, so that the power supply
is on the right hand side, or vertically so that the power supply is at the lower end.
The necessary accessories for mounting the central cabinet on the wall are included in the delivery: 4 wall
plugs for a hole with a diameter of 8 mm and a depth of not less than 40 mm, and 4 screws of dimensions
5,5x38 mm. The distances between the holes, when mounting the cabinet horizontally, is 300 mm

SL1000 Compact, System manual 16(57)
horizontally and 220 mm vertically. (The positions of these holes are marked on the cover of the central
package, which can be teared off and used as help in the drilling.)
It is very convenient to install two user terminal sockets just next to the central cabinet: one to function as
the socket for the programming terminal, and one to function as the socket for a maintenance terminal,
see section 3.2.3.
With the help of these two sockets it is possible to test all the connection numbers of the central simply by
moving the cables of the sockets from one number to another on all connection cards, which is of great
help when searching for faults in the central or for damaged cables between central and user terminal.
If a junction box or some other form of intermediate termination is used in the cabling at the central's end,
see section 2.2, this box should be installed close to the cabinet noticing that the inlet for the cables is on
the right hand side of the cabinet in horizontal installation (at the bottom in vertical installation). The end
plate of the cabinet is fastened with four screws and can be removed to make the connecting of the
cables easier. Especially in small system, say 20 user terminals or less, one can do without the
intermediate termination by bringing the cables directly inside the cabinet. The cable opening in the end
plate is equipped with a screw tightened bracket for strain relief of the cables.
Standard telephone network installation practices should be followed in the cabling. The cables should be
laid so that they are protected against physical damage and against interference from high frequency,
heavy current or high voltage cables and devices.

3.2 THE CONNECTING OF THE UNITS
3.2.1 THE CONNECTION CARDS
The 4-wire cables from the user terminals are connected directly, or via an intermediate termination box,
to the 4-pole screw connectors on the connection cards. The connectors consist of a socket and a plug
part, and the unfastening of the plug during the connection procedure makes the job easier. Figure 6
shows how the connection numbers 10-41 are located on the cards and how the two twisted pairs A, B
and C, D should be connected to the plug.

3.2.3 THE PROGRAMMING TERMINAL AND THE MAINTENANCE TERMINAL
Close to the central cabinet two ESMI wall sockets are installed, one as the socket for the user
programming terminal and the other for use during the taking into use of the system, and later for use
during maintenance. The connecting of these two sockets is shown in figure 8.

3.2.4 THE RELAY CARD
The optional relay card RC-4 of the Compact central has four relays, each with a normally open potential
free contact. The connection of the 4 pairs of wires from the contacts uses two 4-pole screw connectors of
the same type as on the connection cards foe the user terminals, so it is important to take care that the
terminal and relay cables are not intermixed. Figure 9 shows how to connect the wires from the four relay
contacts.

The relay contacts:
The maximum allowed current is 5 A, if the voltage is lower than 24 V DC or 49 V AC. The maximum
voltage is 48 V DC or 49 V AC. The contact are rated for 1x105operations. If the current or the voltage is
close to the maximum ratings, it is recommended to use intermediate relays to increase the relay life time
and to decrease the size of the transients generated from the relay contacts. The two wires of the part of
each relay cable which is located inside the cabinet should be twisted.
3.2.5 THE REAL TIME CLOCK CARD
If the optional real time clock RTC is taken into use, the two pins close to the battery must be
interconnected with a piece of wire to give the clock circuit supply voltage. The card is delivered without
these two pins connected, so that there is no load the battery.

3.2.6 THE SERIAL COMMUNICATION CARD
The SCC will be available later.
3.3 TAKING INTO USE
During the taking into use of the system, and later during replacement or addition of cards, it is important
that cards are not removed or added when power is on.
The taking into use procedures, for which it is convenient to have two persons available, so that the
connections between the user terminals can be tested, are the following:
1. Before any connection cards or optional cards are connected to the central: Connect the
central to the mains and check that the three voltage LEDs (+30 V, +5 V, -5 V) on the
processor card are lit.
- if all three LEDs are off, check the primary and secondary fuses
- if one or two are off, see the service manual (probably something wrong with the rectifiers
and/or the +5 V and -5 V voltage regulators or the -30 V stabilizing transistor).
2. Disconnect the central from the mains.
3. When the LEDs are extinguished; put the first connection card in its place, and connect
the user terminal cables (for connection numbers 10-13) to it.
4. Connect the central to the mains.
5. If the cabling hasn't been checked it is recommended that the polarity of the supply voltage
+30 V is checked before the user terminals are plugged into the wall sockets (pole 1 = +30 V,
pole 3 = 0 V, see figure 7 in section 3.2.2). Both the connection cards and the terminals will
tolerate an inversed polarity for a short time period, but this should be avoided.
6. Connect terminals number 10 and 11 (equal to the physical connection numbers) to the wall
sockets, and check that the connection between the two works bothways; call number 11 from
number 10, and number 10 from number 11. (After connecting the terminal to the socket it will
take a few seconds before the terminal will operate: the LEDs will flash once when the terminal
is ready).
7. Connect terminal number 10 directly to the central: use the socket installed for maintenance
use, if there is one as recommended, see figure 8 in section 3.2.3, or connect the terminal
directly to the connection card.
After this one of the two persons carrying out the taking into use will stay by the central cabinet,
adding more connection cards as the taking into use proceeds, and keeping record of the
functioning or malfunctioning connection numbers. The other person moves from terminal to
terminal in number order.
8. Check that the connections 10-12 and 10-13 work bothways.
9. Disconnect the central from the mains.
10. Add connection card number 2 (connection numbers 14-17) to the central.
11. Connect the central to the mains.
12. Check that the connections 10-14, 10-15, 10-16 and 10-17 work bothways.
13. Repeat steps 9-12 for connection cards 3-8 (connection numbers 18-41) depending on the size
of the system.

SL1000 Compact, System manual 20(57)
14. If optional cards (real time clock card, relay card, serial communication card) are included in the
system, these are added to the central when power is off. Necessary connections are
performed, see sections 3.2.4 to 3.2.6, and the power is connected on.
15. Move the terminal connected directly to connection number 10 to the socket for the
programming terminal, and connect the cable going to the real location of terminal number 10 to
connection number 10.
16. Perform the user programming of the system, e-g- the free numbering of the system, following
the instructions of chapter 6, after which the programmed terminal numbers are to be used
instead of the connection numbers 10-41.
Even if no special programming is needed, the clock of the system should be set, except if all
user terminal are without display. This setting of the clock can be done from the programming
terminal, or alternatively from any terminal to which the priority right has been given. Connection
number 10 has initially this priority right without programming, so in certain cases the user
programming can be left completely undone, and the system will work in its basic form.
17. Check the functioning of the optional relay and serial communication cards.
18. Disconnect the terminal used as the programming terminal, and take it to its right place at
connection number 10. Perform the setting of the clock (setting sequence M i H1H2M1M2,
where H1H2= the hours, M1M2= the minutes), if it hasn't been done from the programming
terminal.
19. Fill in the taking into use form of the system.
The person carrying out the taking into use fulls in the form, paying special attention to the
program version and the special features of the system, because these are important for future
expansions and possible maintenance.
The various parts of the taking into use are marked as accepted, or the observed malfunctions
or defects are noted. If there are no defects, or if these are minor, and the time or repairing them
is agreed on and put on the form, the form is marked with the date, and both the customer and
the person which has taken the system into use as a representative of the supplier sign the
form, thus accepting the taking into use.
The warranty period of the system begins from the signature date, or the date separately agreed
on and marked on the form. The warranty certificates of all units are collected and filled in with
the date. The originals of the certificates are left with the customer, the copies are sent to the
manufacturer together with the last page of taking into use form. The first page of the form stays
with the customer, the second page is given to the supplier.
4. FAULTFINDING
With the help of the faultfinding guide on the following pages, the most probable fault situations of the
Compact system can be located and taken care of. The locating is, in practice, done by replacing the
suspected unit (user terminal, connection card, cable, integrated circuit) with a functioning one. No
soldering iron is needed: If the fault is located to the processor card, which does not have a replacement
unit, the replacement of two of its integrated circuits mounted into sockets (the 8085A and the 8155) is
tried, but the guide does not go any further. If these replacements do not help, please refer to the separate
service instructions for the system.
Whenever replacing units of the central, that is connection cards, optional cards or integrated circuits,
please note that this must not be done when power is connected to the central: before removing or adding
cards or components, check that the three processor card LEDs (+30 V, +5 V, -5V) are off.
Possible fault situations can roughly be divided into four categories:
1. The fault is related to one particular user terminal
2. The fault is related to several or all user terminals connected to one particular connection card
3. The fault is related to several user terminals connected to several particular connection cards
4. The fault is related to the total system, no user terminal is functioning
