Please read this operating manual before starting up carefully.
Observe the installation and connecting instructions.

Before operation, the unit must be configurated for its intended purpose under an expert guidance.

(e.g. controller type, sensor type and range, alarm adjustment etc.)

See: „Configuration Level“ and „Parameter Level“
Attention: The „heating“- or „cooling“-outputs can be active while programming or configuring the controller.

This can cause a damage either to the plant itself or its contents.

Disclaimer of liability

We have checked the contents of the document for conformity with the hardware and software described. Nevertheless, we are unable
to preclude the possibility of deviations so that we are unable to assume warranty for full compliance. The information given in the
publication is, however, reviewed regularly. Necessary amendments are incorporated in the following editions.
We would be pleased to receive any improvement proposals which you may have.

The information contained herein is subject to change without notice.

It is not permitted to connect the grounds of the sensor- and bist. voltage-outputs with each other.

Control output OUT 1:

2-point-controller: "Heating" e.g „Cooling“
3-point-controller (heating-off-cooling): „Heating“

Control- or alarm output OUT 2:

2-point-controller: "Alarm 2“
3-point-controller: „Cooling“

Alarm Output OUT 3: „Alarm 3“

IV. Installation Instructions

Make certain that the devices described here are used only for the intended purpose.
They are intended for installation in control panels. The controller must be installed so that it is
protected against impermissible humidity and severe contamination.
In addition, make sure that the permitted ambient temperature is not exceeded.

The electrical connections must be made according to the relevant locally applicable regulations.

If using a thermocouple sensor, the compensation cables must be laid directly to the controller
terminals.
Transducers must be connected only in compliance with the programmed range.
Transducer cables and signal lines (e.g. logic or linear voltage outputs) must be laid physically
separated from control lines and mains voltage supply cables (power cables) and must be shielded.
Spatial separation between controller and inductive loads is recommneded.
Interference from contactor coils must be suppressed by connecting adapted RC-combinations
parallel to the coils. Control circuits (e.g. for contactors) should not be connected to the mains power
supply terminals of the controller.

IMPORTANT:

Before operation, the unit must be configurated for its intended purpose
(e.g. controller type, sensor type and range, alarm adjustment etc.).
Please see „Configuration Level“.

V. Display and Keyboard

Display PROCESS : Process Value
Display SET : Setpoint Value

LED OUT 1: Output OUT1 active: Control Output
LED OUT 2: Output OUT2 active: Control Output or Alarm Output A2
LED OUT 3: Output OUT3 active: Alarm Output A3

P

Parameter key

Adjustment of chosen parameter (e.g. setpoint) to higher or lower values.

Short operation: single-step adjustment
Longer operation: quick-scanning
When the parameter adjustments have been altered but not with key „E“ entered,
the display will flash bright/dark.

E

Confirmation and storage of the pre-selected values

The display will shortly be switched dark as a control of this function.

P

Sets the parameter back to the originally stored value.

Any altrations made to the parameters, that are not confirmed (E-key) within
30 seconds, will not be accepted and the parameter will return to ist originally
stored value.
