NOTE
The terminals IN1, IN2, AUX, GND, Ext. Off and MP meet the require-
ment for "safe isolation" (in acc. with EN61800-5-) to the mains ter-
minals, as well as to the SBM and SSM terminals (and vice versa).
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
Type of signal: Current (0-20 mA, 4-20 mA)
Input resistance: R = 500 Ω
i
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.
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
i
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.
Can be configured in the service menu <5.1.3.2>
The AUX terminal responds to the presence of an impulse.
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.
Interface for dual pump function
The pump can be switched on/off via an 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>).
Minimum permitted: 12 V DC, 10 mA
Maximum permitted: 250 V AC, 1 A
tact) is available at the SSM terminals (menu <5.1.5.0>).
Minimum permitted: 12 V DC, 10 mA
Maximum permitted: 250 V AC, 1 A
The optional IF-Module is pushed into the multi-plug in the
terminal box.
The connection is twist-proof.
