Notes
Three-phase current 3~400 V AC, 50 Hz, IEC 38.
Type of signal: Voltage (0-10 V, 2-10 V)
Input resistance: R
≥ 10 kΩ
i
Contact load: 24 V for a short time
Type of signal: Current (0-20 mA, 4-20 mA)
Input resistance: R
= 500 Ω
i
Contact load: 15 V, 30 mA for a short time
Can be configured in the service menu <5.3.0.0>
Connected at the factory via the M12 threaded connection
(Fig. 2), via (1), (2), (3) according to the sensor cable designa-
tions (1,2,3).
IN can be used as the input for remote setpoint adjustment in
all operating modes.

Contact load: 15 V, 30 mA for a short time
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.
Pump cycling can be performed using an external, potential-
free contact. One-time bridging of the two terminals will
cause external pumping to take place, if it is enabled. Bridging
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 dual pump function
The pump can be switched on/off via the external potential-
free contact.
In systems with a high switching frequency (> 20 on/off
operations per day), switching on/off must take place via
"Ext. Off".
Can be configured in the service menu <5.1.7.0>
Contact load: 24 V DC/ 10 mA
Potential-free individual run signal/collective run signal
(changeover contact), operation readiness signal is available
at the SBM terminals (menus <5.1.6.0>, <5.7.6.0>).
Permitted minimum: 12 V DC, 10 mA
Permitted maximum: 250 V AC, 1 A
contact) is available at the terminals SSM (menu <5.1.5.0>).
Permitted minimum: 12 V DC, 10 mA
Permitted maximum: 250 V AC, 1 A
The optional IF-Module is pushed into a multi-plug in the ter-
minal box.
The connection is twist proof.
