ANALOG INPUTS
The analog inputs (4-20 mA) cover pressure measurements and, if applicable, brine temperature measurement
and motor current measurement.

ANALOG INPUTS 4-7
The terminals in the panel are designated "A IN 0" to "A IN 7".
A IN 3
MOTOR AMPERE
Displays the signal on analog input 3 (A IN 3), where 4-20mA corresponds to 0-100%. If this
value is multiplied with the transformer factor (setp. I/F5) you will get the motor current, which is
displayed on the initial picture (= display picture 1).
A IN 2
P-OIL PRESSURE B
The oil pressure in bars measured by the pressure transmitter in the oil manifold. 0-25 bar gauge
(= 1-26 bar absolute) corresponds to a signal from the transmitter of 4-20 mA.
Note: The read-off displayed is the absolute pressure (bar a).
A IN 1
P-DISCHARGE B
The oil pressure in bars measured by the pressure transmitter in the oil separator. 0-25 bar gauge
corresponds to a signal from the transmitter of 4-20 mA.
A IN 0
P-Suction
The suction pressure in bars measured by the pressure transmitter in suction valve. -1-+6 bar gauge
(=0-7 bar a) corresponds to a signal from the transmitter of 4-20 mA.
