Sensor connection, standard Ex version without Dry Running Switch (SL pumps)
Pos. Description
A 3 × PTO
B 2 × Moisture switch (motor top)
K Leakage switch
J 3 × PTC
Cable screening must be connected to the ground. Sensor wire 7 is the control wire for service. If not used, then
the wire end must be insulated. To connect the leakage switch to SM113 module, use resistor kit 92726268. The
resistor converts the digital signal from the leakage switch (Terminal 4, 5 and 6) must be converted to analog
4-20 mA signal. The resistor kit must be connected as follows:
1. Connect Sensor wire "4" (common point of leakage switch) to SM113 Terminal "3".
2. Connect Sensor wire "5" (leakage switch lower position: 4-6 mA = "OK" signal) to "R1" of the resistor kit.
3. Connect Sensor wire "6" (leakage switch upper position: 16-18 mA = "Alarm" signal) to "R2" of the resistor
kit.
4. Connect the common end of the resistor kit to Terminal "4" of the SM113 module.
