Waste disposal
3.3 Waste disposal
This symbol means that the product is subject to European
Union regulations on segregated waste disposal. This applies
both to the product itself and to any accessories marked with
the same symbol. Disposal of any such item as unsorted do-
mestic waste is strictly forbidden. Batteries and rechargeable
battery packs are special waste and must not be discarded as
normal domestic waste. Please dispose of packaging materials,
plastics, and electronic components separately and in the
proper manner.
4. SAFETY NSTRUCT ONS
CAUT ON! This sign is intended to warn the user of a situation
that risks damaging the device. The user should carefully read
the operating instructions in order to avoid possible errors, dam-
age to equipment, and even the risk of personal injury. The de-
vice may only be opened by duly authorized and qualified service
technicians.
WARN NG! This sign is intended to warn the user of a possibly
life-threatening situation with risk of fatal injury through high volt-
age. Before connecting any equipment to the power supply al-
ways ensure that the operating voltage is correct. Please note
that the device may be susceptible to damage by electrostatic
discharge or lightning. Do not run wires in the vicinity of high-volt-
age power cables!
4.1 Special notes on use
If the device is brought into the work-room from a cold environ-
ment there is a risk that condensation might form on the electron-
ics. You are advised therefore to wait until the device has ad-
justed to the ambient temperature before starting to use it.
4.2 Handling batteries / rechargeable batteries correctly
When inserting batteries / rechargeable batteries ensure that
these are correctly polarized. If the device will probably not be
needed for a relatively long period of time or if the batteries are
empty remove the batteries; this will prevent battery acid leaking
onto the device and damaging it. Rechargeable batteries should
be recharged as and when necessary. You should never attempt
to recharge an ordinary (non-rechargeable) battery; it may ex-
plode ! Batteries / rechargeable batteries must never be short-cir-
cuited or thrown on the fire.

5. The simulator functions
5. THE S MULATOR FUNCT ONS
Simulator AL E O® KA7531 is a universal generator of sensor and transmit-
ter variables. For Pt100 sensors it incorporates 5 precision resistors in 4-con-
ductor circuitry. Voltage signals from 7 different thermocouple types with set-
table cold junction temperature are calculated and output via a 16-bit D/A con-
verter. Transmitter signals 0-10 V and 0-20 mA are generated in exactly the
same way. Pt100, voltage, and current signals are electrically isolated from
one another. The output values can be specified digit-by-digit or set manually
in selectable steps or automatically. It even provides continuous ramp genera-
tion with settable limit values. Digital signals of 0.01 Hz to 500 kHz can be
used as frequency with selectable pulse width or pulse / pause duration. A
continuity check is also provided; this measures the voltage drop and, in the
event of the result exceeding a settable threshold, issues an acoustic signal.
The simulator can also, via the interface, be controlled from a PC or operated
in an AL E O® network.
6. CONNECT NG THE S MULATOR
To supply simulator variables to the appropriate devices the simulator incor-
porates 5 AL E O® sockets P0 to P4 (1). The accessories include one
AL E O® test connector (7) with 6 terminals for connecting the Pt100 resis-
tors in 4-conductor circuitry. For all other signals there is the connector with
two-pole cable and banana plugs. For the continuity check test probes are
also provided.
Connection of Pt100 simulator with AL E O® test connector ZA 100-TS in 4-
conductor circuitry (terminals A, B, C, D):
Connection of voltage signals, current signals, digital signals, and continuity
check via 2-contact AL E O® test cable ZA 1000-TK fitted with banana plugs,
(terminals A = +, B = -):

Power supply
7. POWER SUPPLY
Power can be supplied to the simulator in any of the following ways :
3 AA alkaline batteries, in the device
ains adapter 12 V, 0.2 A, with AL E O® connector ZA1312NA1
External DC voltage, 10 to 30 V via AL E O® connector ZA1000FSV
Supply and RS422 network connection via AL E O® connector ZA5099FSV
Supply and USB connection via AL E O® data cable ZA1919DKUV
7.1 Battery operation and supply voltage monitoring
The measuring instrument is powered by 3 AA alkaline batteries. Basic current
consumption is approx. 30 mA; this will give an operating time of approx. 70
hours. If the display illumination is left switched on, this operating time will be
reduced to approx. 30 hours. If the current output is often used the batteries
may last as little as 15 hours. The available operating voltage is displayed in
the device configuration (see 9.4), thus allowing you to assess the remaining
operating time. As soon as the remaining battery capacity drops to approx.
10%, the battery symbol ´´µµµµµµµµµ¶ in the softkey bar of the displays will start to
flash and display illumination is switched off. If the batteries are completely dis-
charged the device itself will switch off. To replace old batteries unscrew the
battery compartment cover (6) on the rear of the device.
To save on battery use when in battery mode the electrically isolated
current / voltage signals P1 and P2, so long as they are not selected,
are switched off.
7.2 External power supply
Via the simulator it is also possible to draw power from an external source -
preferably using mains adapter ZA1312NA1 (12 V / 0.2 A) connected via the DC
socket (3). Please ensure that the mains voltage is correct. At this socket it is
also possible, via an AL E O® connector (ZA1000FSV) to connect a DC volt-
age from 9 to 12 V (minimum 0.2 A). Another interesting possibility is the com-
bined connection of power supply and interface to the AL E O® network via
AL E O® connector ZA5099FSV or to a USB interface via AL E O® cable ZA
1919-DKUV.
With an external supply all outputs can be used simultaneously.
7.3 Switching ON / OFF, reinitialization
To switch the device ON briefly press and release the key ON (5) in the middle
of the keypad; to switch the device OFF press the key ON and hold down. If
interference (e.g. electrostatic) or a malfunction (e.g. battery failure) causes the
device to behave abnormally, it can be reinitialized; to do so press key F2 .
when switching on. This will restore all settings to the factory default status.

9.4.4 Baud rate, data format
On leaving the factory the baud rate for all interface modules is programmed to
9600 baud. In order to avoid unnecessary problems when networking several
devices together the baud rate should not be altered; instead, the computer
should be set to match. If for some reason this proves impossible you can, in
the ´Baud rate´ function, choose a value from 1200 / 2400 / 4800 / 9600 baud
or 57.6 / 115.2 kilobaud. Set the baud rate in the function (s. 8.2):Baud rate: 9600 bd

9.4.5 Device address
To communicate with networked devices it is absolutely essential that all the
devices concerned should have the same baud rate setting but that each
should have its own dedicated address; this is because only one device should
respond per command. Before starting network operation ensure therefore that
all the measuring instruments and modules involved are assigned different de-
vice addresses. On leaving the factory address 00 is normally set.
Set the device address in the function (see 8.2): Device address: 00
10. SER AL NTERFACE
All ports can be controlled not only by pressing the appropriate keys but also,
with option I, via the serial interface; (see anual, Chapter 6). For connecting
to socket A1 (2) various data cables are available; (see anual 5.2). The best
way of connecting to a network distributor is on a 6-wire basis via connector ZA
5099-FSV in the DC socket leading to a free RS422 output; (see anual 5.3).
This combines power supply and data transmission.
The same combined connection is also implemented with the new USB data
supply cable ZA 1919-DKUV.
If a data cable or interface connector is plugged in at socket A1 or
DC, key operation on the simulator is - for safety reasons - automati-
cally blocked.
The following should appear in the softkey bar:
