Notes
3~380 V AC – 3~440 V AC, 50/60 Hz, IEC 38
Type of signal: Voltage (0-10 V, 2-10 V)
Input resistance: R ≥ 10 kΩ
i
Type of signal: Current (0-20 mA, 4-20 mA)
Input resistance: R = 500 Ω

Can be configured in the service menu <5.3.0.0>
Connected at the factory via the M12 threaded cable gland, via In1 (1),
GND (2), + 24 V (3) according to the sensor cable designations (1, 2, 3).
In2 can be used as the input for remote adjustment of the setpoint in any
operating mode.
Type of signal: Voltage (0-10 V, 2-10 V) Input resistance: R
Type of signal: Current (0-20 mA, 4-20 mA) Input resistance: R
Can be configured in the service menu <5.4.0.0>
For both input In1 and In2
Max. load: 60 mA
The voltage is short-circuit proof.
Contact load: 24 V DC/10 mA
Pump cycling can be performed using an external, potential-free contact.
If external pump cycling has been previously activated, bridging the two
terminals once executes a pump cycling operation. Bridging them a second
time will cause the procedure to repeat, provided the minimum run time is
adhered to.
Can be configured in the service menu <5.1.3.2> Contact load:
24 V DC/10 mA
Interface for twin-head pump function
The pump can be switched on/off via the external potential-free contact.
Systems with a high switching frequency (> 20 on/off operations per day)
should be switched on/off via "External off".
Can be configured in the service menu <5.1.7.0> Contact load:
24 V DC/10 mA
