precautions should be taken.
3 ELECRICAL WIRING
Refer to Drawings A, B, C & E
When installing the equipment in an area which is likely to be hazardous from Ignitable
Dusts, use liquid tight conduit and fittings and follow all local codes.
4 OPERATING INSTRUCTIONS
The Fieldbus Adapter is a self contained unit and there are a number of user configurable
options. The adapter is equipped with three communications ports; RS232, RS485 and
Profibus DP.
The RS232 is a simple interface which can be used for diagnostics purposes. The data
from this port is formatted to work with a VT100 display terminal. Any terminal or
terminal emulator capable of supporting the VT series or compatible commands can be
used with this port although the data has been optimised to work with VT100. The
RS232 port operates at a fixed data rate of 9600, N, 8, 1.
The RS485 port is a four wire, twin twisted pair full duplex serial port and has been
specifically configured to work with the Watchdog communications network. You
should not connect any other devices to this port unless you wish to monitor the
Watchdog data directly. If this is the case then contact your supplier for details relating
to the Watchdog communications protocol.
The Profibus interface provides the following:
Transmission media: Profibus bus line, type A or B specified in EN50170
Topology: Slave configuration
Fieldbus Connector: 9 pin female DSUB
Cable: shielded copper; twisted pair
Optically isolated bus A and B termination
Address range 1-99 selected by on board switch
Maximum cyclic I/O data size of 244 bytes
Optional bus termination, switch selectable
Led status indication

Watchdog NTC to F500 PGW CAI REV0 July 2014

The above diagram shows the location of the main parts of the Profibus module.
The address switches allow the unit slave address to be set between 01 and 99. The left
hand switch sets the ten’s digit of the address and the right hand switch sets the unit digit
of the address. If you decide to change the address then you must reset the interface by
first removing and then reconnecting power. The default unit address is 77.
The termination switch can be used to add termination resistors to the Profibus interface
if required. If the F500 Profibus interface card is the first or last module on the Profibus
network, then the switch needs to set to ON, otherwise it must be set to OFF.

The Watchdog speed is encoded in the following manner. Four hexadecimal digits are
used to represent the measured speed for the Watchdog. The rightmost three and a half
are the main body of the speed and the upper half of the fourth is the position of the
decimal place within the information. If the most significant two bits are ‘00’ then
decoding of the speed is not required. If the two bits are ‘01’, then the resulting value
should be divided by 10 and if the two bits are ‘10’ then the speed should be divided by
100. The top two bits should never be ‘11’ as this has no meaning.

Not used.
An example of this can be seen below.
Watchdog speed = 6E (e.g. byte 3) & 1E (e.g. byte 2). The leftmost digit (6) = ‘0110’ in
binary which can be separated into ‘01’ (bits 7 and 6) for speed scaling and ‘10’ (bits 5
and 4) for the upper speed digit. If you strip off bits 7 and 6 you are left with a decoded
value of 2E & 1E for the speed and ‘01’ or divide by 10 for the scaling. The speed 2E1E
converted to decimal = 11806 and then divided by 10 results in an actual speed of 1180.6.
By default the Watchdog will display speed in pulses per minute but it can be scaled to
display any value required, refer to the Watchdog manual for further detail.
The Watchdog status is encoded as described in the following manner.
Two data bytes are used to represent the status for the Watchdog. The first status byte
(e.g. byte 5) is the status code and the second byte (e.g. byte 4) represents any data which
is associated with the status code. All data is in hexadecimal.

An example of the status code might be ‘2463’. The first status byte (byte 5) ‘24’ show
that the equipment is running within the specified alarm limits and the second status byte
(byte 4) ‘63’ indicate that the speed is 99% if it’s calibrated value. Where a value is not
shown or a ‘-‘is used in the table, this indicates that any data present in this field should
be ignored.

Under speed alarm and stop in % (Byte 7, 6)
These two bytes show (in % of calibrated speed) the under speed alarm and stop levels.
These represent the point at which the Watchdog will generate an alarm or stop condition.
Example, if byte 7 is ‘0A’ and byte 6 is ‘14’ then this means that the Watchdog will
generate an under speed alarm at 10% (0A) below calibrated speed and will generate a
stop condition at 20% (14) below the calibrated speed.
Over speed alarm and stop in % (Byte 9, 8)
These two bytes show (in % of calibrated speed) the over speed alarm and stop levels.
These represent the point at which the Watchdog will generate an alarm or stop condition.
Example, if byte 7 is ‘0A’ and byte 6 is ‘14’ then this means that the Watchdog will
generate an over speed alarm at 10% (0A) above calibrated speed and will generate a stop
condition at 20% (14) above the calibrated speed.

Watchdog NTC to F500 PGW CAI REV0 July 2014

Current calibration value in PPM (Byte 11, 10)
These two bytes represent the current calibration speed value in Pulses Per Minute
(Default). The representation can be changed to other scaled values by using the display
scaling value below. Refer to the Watchdog manual for further details about display
scaling.
Display scaling factor (Byte 13, 12)
These two bytes contain a value which is used by the Watchdog to scale the information
on the display into a format which represents more accurately what the elevator is doing.
The default scaling factor (04B0) results in the display showing the current speed in
PPM. Refer to the Watchdog manual for further details about display scaling.
NTC Temperature 1 and 2 (Byte 15, 14)
These two bytes show the actual temperature of temperature sensors 1 & 2. The values
are in Dec C or Deg F according to the settings on the Watchdog. Refer to the Watchdog
manual NTC section for more detail.
NTC Temperature 3 and 4 (Byte 17, 16) & NTC Temperature 5 and 6 (Byte 19, 18)
See the detail above for temperature sensors 1 and 2
NTC temperature sensor status 1 and 2 (Byte 21, 20)
These two bytes show the current status of temperature sensors number 1 & 2.
If byte 21 is 0 then sensor 1 is NORMAL
If byte 21 is 1 then the temperature of sensor 1 is HIGH so an alarm has been generated.
If byte 21 is 2 then sensor 1 may be OPEN circuit
If byte 21 is 3 then sensor 1 may be SHORT circuit
NTC temperature sensors 2 to 6 operate in an identical manner as described for
sensor 1 above.
Sensor 1 and sensor 2 alarm level (Byte 27,26)
These two bytes represent the alarm value for the temperature sensor. The default values
for this alarm level are ‘9E’(158) when measuring in Deg ‘F’ and ‘50’(80) when
measuring in Deg ‘C’. Refer to the Watchdog manual for further detail regarding this
value.
Sensor 3 and sensor 4 alarm level (Byte 29, 28) & Sensor 5 and sensor 6 alarm level
(Byte 31, 30) operate in an identical manner as described above.
Number of sensors in use (Byte 33)
Byte 33 shows the total number of NTC temperature sensors that are currently being
monitored by the Watchdog. This value ranges from 0 to 6. See the watchdog manual
for further detail.

Watchdog NTC to F500 PGW CAI REV0 July 2014

Relay status (Byte 32)
This byte contains information relating to the status of the Watchdog LED’s and Relays.
Although the byte is represented in Hexadecimal converting it to binary helps to explain
the contents a little better.
0000:0000 The left hand four bits are always 0000 and can be ignored.
0000:0000 The right hand four bits contain the following information.
: This bit indicates the condition of the STOP Led (1=ON: 0=OFF)
: This bit indicates the condition of the ALARM Led (1=ON: 0=OFF)
: This bit indicates the condition of the STOP Relay (1=ON: 0=OFF)
: This bit indicates the condition of the ALARM Relay (1=ON: 0=OFF)
Not used and always ‘0000’
When a relay is considered to be ‘ON’ we mean energized and when ‘OFF’ we mean de-
energized.
0000:0000 = 00 then no conditions exist
0000:0010 = 02 then the alarm Led is on
0000:1010 = 0A then the alarm Led and Alarm Relay are active
0000:0011 = 03 then both Led’s are ‘on’ and both Relays are ‘off’ (de-energized)
Persistent alarm value NTC only (Byte 35)
This is how long the temperature alarm will take in seconds before stopping the elevator.
The default value is ‘B4’ 180 seconds. If this value reaches ‘0’ then the elevator will be
stopped.
Update counter (Byte 34)
Every time the F500 successfully receives information from the chosen watchdog, then
this counter value will be incremented by 1. The watchdog treats serial communications
as low priority so occasionally requests for data can be ignored. It is advisable to keep
checking this value so as to know when new data has arrived in the F500. The counter
will increment from 0 to 255 and then return to 0 again in a continuous loop.
Below is an example of the data returned when the F500 is polling Watchdogs

1 isn’t present at this time. Words 18 to 34 (green) represent Watchdog 2. Word 18
which is 0484 HEX tells us that the Watchdog is currently running at 1156 pulses per
minutes. Word 19 which is 2465 HEX tells us that the Watchdog is ‘running (24) at
101% (65) of the calibrated speed. The remainder of the information in the example can
be decoded using the information as previously described. Words 35 to 51 (blue)
represent Watchdog 3. Word 35 which is 0000 HEX tells us that the Watchdog is
currently NOT running. Word 36 which is 4100 HEX tells us that the Watchdog is in
fact NOT calibrated (41), see the Watchdog manual for more detail about calibration.
Diagnostics Display.
The F500 Elite is equipped with a simple RS232 serial interface. This interface can be
used to monitor the communications with the Watchdog Elite. The information displayed
contains diagnostic data about the Fieldbus module and Watchdog number 1. A VT100
or compatible display terminal should be used to display the information.
Above is an example screen image from the diagnostics display. The information
displayed will vary slightly dependent upon the fieldbus interface used.
CBU Version = X.XX –This is the control base unit software version.
API Version = X.XX –This is the application interface software version.
FBI Version = X.XX –This is the Fieldbus interface software version.
ABI Version = X.XX –This is the AnyBus interface software version.

Fieldbus type = Profibus DP –This describes the type of Fieldbus module which is
installed in the F500 Elite. If the Fieldbus module is faulty some or all of this data will
change to suggest which area may be at fault. For example, FBI version number might
become 245.55. An unusually large number such as this is not usually associated with a
normally functioning module and would suggest that the Fieldbus interface controller has
failed. In the event of this or any other fault, contact your supplier.
The sequence S2468E indicated that the system has initialised correctly, a deviation from
this indicates that one or more parts of the initialisation process has failed. If this is the
case, recycle power and see if this clears the problem. If you still have problems with the
initialisation of the unit contact your supplier and tell them what you see on the
diagnostics display. The main area of the display shows the complete data from
Watchdog address number 1 as described on pages 9 to 15 of this manual.
Diagnostics LED.
Located on the main circuit board, just above the RS485 connections to the Watchdog
you will find an LED indicator (usually RED). This indicator will flash every time the
F500 attempts to communicate with the Watchdogs. The LED will normally flash at a
consistent rate followed by a very short pause. The short pause indicates that the F500 is
updating the information which it stores internally. A significant deviation from this
sequence is an indication that there is a problem. If this happens, contact your supplier
for further information.

CHECK LIST
For problems after initial start-up
1. Is there excessive interference on the electrical power supply? Power
conditioners and surge (spike) suppressor may have to be fitted.
2. Has the wiring for the Watchdog and Fieldbus been routed away from power
cables?
3. Is the F500 Elite circuit properly grounded?
4. Is the Micro-processor control unit overheating, if so mount in temperature-
controlled environment of maximum temperature 104°F (40°C).
5. Check that high powered ‘Walkie Talkie’ radios are not operated immediately
near the control unit or Watchdogs as this will affect the performance.
6. Check that the communications/power cable is connected correctly and in
accordance with DRG A,B,C and E.
7. Check that there is no exception status reported.
8. If only part of the diagnostics data is displayed on the terminal screen then turn
the F500 Elite off then back on again without removing power to the display
terminal.
9. If the Watchdogs are not responding or are intermittent, check that the termination
resistors are correctly fitted.
