8.4 Pressure control for condensers refirgeration 3.01 .. 3.04
8.4.1 Basic setting
3.01 .. 3.04
Basic device settings are carried out in two steps:
1 Place the internal plug (jumper) for the external default signal in the correct position. Caution – not under voltage!
Observe the safety notices!
2 Switch the voltage on and select mode of operation (general controller function) factory setting 1.01 = speed controller.
If necessary configuration of sensors.

Type of signal Input Analog IN 1 INFO
0-10 V
No PINs with
jumper bridged
For pressure sensor with 0-10 V signal
proportional so measuring range
Factroy setting !
0-20 mA / 4-20 mA
Lower PINs
with jumper
bridged
Pressure sensor with 4-20 mA signal
For Ziehl-Abegg pressure sensors type
DSF2-25 put in down position
Connection for pressure sensor type DSF..at „Analog IN 1“
Input 2 is automatically activated upon selection of operating modes with 2-sensors
3.03 and 3.04. The jumpers E 2.1 (J2)
and E 2.2 (J3) must be inserted in accordance with the sensor signal.
