<§> Symbolizes the factory adjustment of the respective parameters.
2Installation Instructions
Make sure the device is used for the intended purpose only.
A4000 indicators are designed for installation in control panels.
Protect the device against impermissible humidity and contamination.
The permitted ambient temperature range may not be exceeded.
Electrical connections must be made according to valid regulations and by properly qualified
personnel.
If using thermocouple sensors, compensation lines have to be connected directly to the indi-
cator terminals. Sensors may be connected only in compliance with the programmed range.
Sensor cables and signal lines (e.g. logic or linear voltage outputs) must be laid separately
from control lines and mains voltage supply cables (power cables).
In order to maintain CE-Compliance screened detectors - and signal lines have to be used.
It is not permitted to connect the grounds of the sensor-inputs and logic-outputs with each
other.
Separate installation of indicator and inductive loads is recommended.
Interference from contactor coils must be suppressed by connecting adapted RC-combina-
tions parallel to the coils.
Control circuits (e.g. for contactors) should not be connected to the mains power supply ter-
minals of the indicator.
The configuration parameters (Window: System) are generally to be selected first.
Disclaimer of Liability
The contents of this document is checked for the conformity with the hardware and software

publication is reviewed regularly. Necessary amendments are incorporated in the following
editions.
We would be pleased to receive any improvement proposals which you may have.

ject to special treat-
ment and must be

If 12 or 16 zones are required, an 8-zone indicator and an expansion module R4010 (4 or 8
zones) must be ordered.
The E-bus on the A4000 is required for communication with the R4010.
If the required indicator already has a fieldbus interface, then the E-bus interface is already
available.
If no fieldbus interface is required, key 90 (E-bus) must be selected for the fieldbus.

It is not permitted to connect the grounds of the sensor-inputs and logic-outputs with each
other!
RTD Ni120: The parameter “Sensor Settings Sensor” has to be set accordingly to the con-
nection diagram (2-wire 3-wire)
4.4 Connection Diagram: Logic Outputs
The power supply for the logic outputs has to be wired ex-
ternally:
+24V have to be applied to the terminals B3 and G3.
B3 is connected internally to E3 and G3 is connected to K3.
So the terminals E3 and K3 can be used to loop the +24V.
The 24V are switched to the outputs out x and thus control
the SSRs. Reference potential is the ground of the supply
voltage.

4.5 Connection Diagram: Relay Outputs
4.6 Connection diagram Continuous outputs (option)
If continuous outputs are existed, the relay outputs are not available.
The GND connection terminals C5 - C7 and H5 - H7 are bridged. The output automatically
switches to current or voltage, depending on the connected load.
4.7 Connection diagram E-Bus for extension module
The extension module R4010, for exptension to 12 or 16 zones, is
connected to the A4000 via the E-bus.
The lines „E-Bus L“ and E-Bus H“ must be connected to the
corrosponding terminals of the R4010.
The connection must be designed as a shielded cable. The shield has
to be conneted the earth (housing) at the R4010 side.

The serial fieldbus module (Type: 03) contains the three interfaces RS232, RS485 und TTY.
By choosing the connection and setting the parameter ”HW-config“ the desired bus is
selected.
Typ 09: Profibus
The 5V-Supply is designed for the
supply of the termination resistors.
Further loads are not allowed.

- line resistance balancing at 2-wire-RTD
- Correction of the control deviation when

If for example the offset value is set to +5°C, then
the real temperature measured by the sensor is
