NOTICE:
The terminals In1, In2, AUX, GND, Ext. Off and MP meet the require-
ment for "safe isolation" (in acc. with EN 61800-5-1) to the mains
terminals, as well as to the SBM and SSM terminals (and vice versa).
NOTICE:
The control is designed as a PELV (protective extra low voltage) cir-
cuit, meaning that the (internal) supply meets the requirements for
safe supply isolation; the GND is connected to PE.

Notices
In2 can be used as the input for remote adjustment of the
setpoint 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.
Contact load: 24 V DC/10 mA
Pump cycling can be performed using an external, potential-
free contact. One-time bridging of the two terminals will
cause external pump cycling 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 twin-head 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
"Extern 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/24 V DC, 1 A
contact) is available at the SSM terminals (menu <5.1.5.0>).
Permitted minimum: 12 V DC, 10 mA,
Permitted maximum: 250 V AC/24 V DC, 1 A
The optional IF module is pushed into a multi-plug in the
terminal box.
The connection is twist proof.
