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
Type of signal: Current (0 ... 20 mA, 4 ... 20 mA)
Input resistance: R
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 names (1, 2, 3).
In2 can be used as input for remote setpoint adjustment 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
Load: max. 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 was activated previously, a single bypass of the
two terminals will perform a pump cycling. Rebypassing repeats this pro-
cess while maintaining the minimum runtime.
Parameterisable in 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.
In systems with higher switching frequency (> 20 switch-ons/switch-offs
per day) switch-off via "External off".
Parameterisable in service menu <5.1.7.0> Contact load: 24 V DC/10 mA
