2. In accordance with the wiring diagram, insert the above two
Pt1000 wires into the connector that will be inserted into the SM
113.
3. Mount the SM 113 to the PVS-3 bracket. Note the correct
orientation of the SM 113 on the bracket. The required torque is
4 ± 0.4 Nm (3 ± 0.3 lb-ft). A suitable anti-seize grease is
required on the screw thread.
4. Mount the PVS3 bracket to the stator housing.
5. Connect the SM113 earth wire to the foot of the PVS-3 during
the mounting of the bracket.
6. Bring the sensor wires around in front of the power wires, and fix
the sensor wires in the clamps (1 ± 0.15 Nm [0.7 ± 0.1 lb-ft), in
accordance with the wiring diagram.
7. When mounting the sensor wires in the clamps, note that the
wire shield must be in the middle of the clamp.
8. In accordance with the wiring diagram, insert the sensor wires
into the SM 113.
9. The resistor needs to be inserted into the SM 113, as per the
wiring diagram. As the pump uses glycol instead of oil, it does
not have a WIO sensor. As such, the resistor simulates a WIO
circuit. Note: The SM 113 is designed to be connected to a WIO
sensor. If the resistor is not inserted, the IO113 indicates false
alarms.
10. Insert wires into the WAGO connector.
11. Secure the WAGO connector to the PVS3 bracket with a cable
tie.
