Device manual
6. Commissioning
Procedure:
Unit properly installed ?
Electrical connection according to valid regulations
and connection diagrams ?
Switch on mains voltage.
When the unit is switched on, all display elements on the
front plate light up for approx. 2 sec. (lamp test).
Then the unit is ready for operation.
Switch over to manual mode.
Does the actual value display PV correspond to the
process variable at the measuring location ?
Actual value display PV is fluctuating/jumping ?
Connecting and setting *digital inputs
- Is the corresponding DI-state text displayed in the
SP-display (e.g. "StOP", "CLOS", ...) ?
Open actuator
- Heating controller: actual value PV rising ?
- Cooling controller: actual value PV falling?
Close actuator
- Heating controller: actual value PV falling ?
- Cooling controller: actual value PV rising ?
Is the bargraph rising while the actuator opens ? *
- bargraph is not rising - all bargraph LEDs stay dark ?
Enter actuating time of connected actuator
Set controller parameters using optimisation
Automatic mode
Manual/automatic switch over
Set setpoint SP
Controller actuating pulses are too short,
switching rate is too high ?
* Option / depending on type of device

Remedy in case of malfunctions:
See 4. Mounting
See 5. Electrical connection
Compare operating voltage (indicated on the type plate) with
mains voltage
See 2.2 Opening/closing the actuator in manual mode
Check sensor, measuring line and electrical connection.
See 5. Electrical connection
Adjust measuring filter FIL. See 3.17 FIL
Unit installed close to powerful electric or magnetic
interference fields ?
Check settings of the digital inputs (see 3.21-3.25)
Check electrical connection (see 5.)
Check voltage supply for digital inputs, external switching
contacts, signal lines and electrical connection.
Consider the display priorities like explained
in 2. Operating and setting.
See 2.2 Opening/closing the actuator in manual mode
No response
Check actuator and electrical connection
controller ↔ actuator
reverse response
Change the actuator control OPEN and CLOSE
