Connection terminal assignment.
- Remove the screws and take off the converter
cover.
NOTE: Terminals IN1,IN2, GND and Ext. Off meet the require-
ments for „safe isolation“ (in acc. with EN61800-5-1) at the
mains terminals as well as at SBM and SSM terminals (and vice
versa).

IN1
Input sensor
Type of signal: Voltage (0 – 10 V, 2 – 10 V)
Input resistance: Ri ≥ 10 kΩ
Signal type: current (0 – 20 mA, 4 – 20 mA)
Input resistance: R

= 500 Ω
Can be configured in the „Service“ menu <5.3.0.0>
IN2
External input setpoint
Type of signal: Voltage (0 – 10 V, 2 – 10 V)
Input resistance: Ri ≥ 10 kΩ
Signal type: current (0 – 20 mA, 4 – 20 mA)
Input resistance: R

GND (x2)
Earth connections
For both input IN1 and IN2
+ 24 V
DC voltage for sensor
Max. load: 60 mA
The terminal is short-circuit-proof.
Aux
Control input (Auxiliary)
„Overriding Off“
for external potential-free switch
The pump can be switched on/off using the external
potential-free contact.
This input is provided for auxiliary functions,
e.g. dry-running sensor, etc.
Ext. off
Control input (ON/OFF)
„Overriding Off“
for external potential-free switch
The pump can be switched on/off using the external
potential-free contact.
In systems with a high cycling frequency
(> 20 on/off cycles per day), on/off-cycling must be
performed via „Ext. off“.
SBM
„Available transfer“ relay
In normal operation, the relay is activated when the
pump is running or in standby.
The relay is deactivated if an initial defect occurs or if the
main power supply is disconnected (pump stops).
Pump availability is signalled to the control box.
Can be configured in the „Service“ menu <5.7.6.0>
Contact load:
Minimum 12 V DC, 10 mA
Maximum: 250 V AC, 1 A
SSM
„Failures transfer“ relay
If consecutive defects of the same type are detected
(from 1 to 6 according to significance), the pump stops
and this relay is activated (until manual intervention).
Contact load:
Minimum 12 V DC, 10 mA
Maximum: 250 V AC, 1 A
PLR
Connection terminals at
PLR
The optional IF-module PLR must be pushed into the
multiplug in the connection area of the converter.
The connection is protected against reversed polarity.
LON
Connection terminals at
LON
The optional IF-module LON must be pushed into the
multiplug in the connection area of the converter.
The connection is twist-proof.
