Fitting the WIO sensor
Fit the sensor next to one of the shaft seal openings.
See fig. 16. The sensor must be tilted into the
motor’s direction of rotation to ensure that oil is led
into the sensor. Make sure that the sensor is
submerged in the oil.
Technical data
7.3.3 Moisture switch
The moisture switch is positioned in the bottom of
the motor. If there is moisture in the motor, the switch
will break the circuit and send a signal to IO 113.
The moisture switch is non-reversing and must be
replaced after use.
The moisture switch is connected in series with the
thermal switch and connected to the control cable,
and it must be connected to the safety circuit of the
separate pump controller. See section 3.2 Electrical
connection.
8. Servicing the product
Input voltage: 12-24 VDC
Output current: 3.5 - 22 mA
Power input: 0.6 W
Ambient temperature: 0 to 70 °C
The motor-protective circuit breaker of the
pump controller must include a circuit
which automatically disconnects the power
supply in case the protective circuit for the
pump is opened.
WARNING
Crushing hazard
Death or serious personal injury
- Do not stand near or under the pump
when it is lifted.

Death or serious personal injury
- Make sure the earth and phase
conductors are not mixed up, follow the
description in the wiring diagram.
- Make sure the earth conductor is
connected first.
WARNING
Electric shock
Death or serious personal injury
- Before starting any work on the product,
make sure that the fuses have been
removed or the main switch has been
switched off and locked in position 0.
Make sure that the power supply cannot
be accidentally switched on.

year.
When the pump is new or after
replacement of the shaft seal, check the oil
level and water content after one week of
operation.
