<< Configuration 01 >>
Line: “Suction temp“, use the and keys to select whether the suction temperature sensor is fitted.
Line: “Oil temp“, use the and keys to select whether the oil temperature sensor is fitted.
Line: “Oil separator“, use the and keys to select whether an oil separator is installed.
Press once. The following selection appears on the display:
Remote SP
Ext temp
Profibus
<< Configuration 01 >>
Line: “Remote SP“, use the and keys to select whether a remote set point as analogue input is fitted.
Line: “Ext temp“, use the and keys to select whether an external temperature sensor is fitted.
Line: “Profibus“, use the and keys to select whether the process data (via Profibus-DP) is to be

Press once. The following selection appears on the display:
Sensor: Psuc
Begin (4mA) 0.0
End (20mA) 10.0
<< Configuration 01 >>
Line: “Sensor“, use the and keys to select the sensor to be scaled.
Line: “Begin (4mA)“, use the digital keyboard keys to enter the selected sensor’s minimum value to be shown in
the display when the sensor’s output equals 4 mA.
Line: “End (20mA)“, use the digital keyboard keys to enter the selected sensor’s maximum value to be shown in
the display when the sensor’s output equals 20 mA.
) For temperature sensors the texts “Offset (K)” and “Span (%)” are shown in stead of “Begin (4mA)”
respectively “End (20mA)”.
