8.4 WIO (water-in-oil) sensor

The WIO sensor measures the water content in the oil chamber 
and converts the value into an analog current signal. The two 
sensor leads are for power supply and for carrying the signal to 
the measuring device or controller. The sensor measures the 
water content from 0 to 20 %. It also sends a signal if the water 
content is outside the normal range (warning), or if oil level is low 
(alarm). The sensor is fitted in a stainless steel tube for 
mechanical protection.
The WIO sensor can be used together with Grundfos IO 113 or 
SM 113, but it can also be used together with other controllers 
with 4-20 mA inputs.
Together with IO 113, the WIO sensor filters the signal and 
provides an easy readout of the actual value. Furthermore, it is 
possible to set a user-defined warning limit and calibrate the 
IO 113 and the sensor to the motor oil.

The WIO sensor works in the following way:

Sensor signals

Technical data

8.5 Pump vibration sensor (PVS 3)

The PVS 3 sensor monitors the vibration level of the pump in 
order to protect the pump and the pipe system against damage. 
A change in the vibration level is an indication of an abnormal 
situation. The reason for this can be a clogged impeller, worn 
bearings, a closed discharge valve etc., indicating that a service 
inspection should be carried out before the pump or the pipe 
system is damaged.

9. Monitoring and control of pump

9.1 IO 113

IO 113 forms the interface between a Grundfos stormwater or 
wastewater pump with analog and digital sensors and the pump 
controller. The most important sensor data are indicated on the 
front panel. See also the installation and operating instructions for 
IO 113 (Publication no. 98097396).
One pump can be connected to an IO 113.
Together with the sensors, IO 113 forms a galvanic separation 
between the motor voltage in the pump and the controller 
connected.
IO 113 with SM 113 enables the following functions:
• protecting the pump against overtemperature
• monitoring the sensors for analog measurement of:

– motor temperature
– pump vibrations
– leakages (WIO)
– stator insulation resistance
– bearing temperature
– digital measurement of moisture in motor

• stopping the pump in case of alarm
• remotely monitoring the pump via RS485 communication 

(Modbus or GENIbus).

Measurement of insulation resistance

IO 113 measures the insulation resistance between a stator 
winding and ground (earth):
• Resistance above 10 M

 = ok

• Resistance between 10 M

 and 1 M

 = warning

• Resistance below 1 M

 = alarm.

9.2 SM 113

SM 113 is used for collecting and transferring sensor data.
SM 113 works together with the IO 113 through power line 
communication using the Grundfos GENIbus protocol.
SM 113 module can be placed either inside the pump terminal 
box (allowing fewer sensor leads out of the pump) or in the 
control cabinet next to the pump installation. For electrical 
connection see fig. 5-8. SM 113 collects data from the following 
devices:
• 3 current sensors, 4-20 mA
• 3 Pt 100 thermal sensors 
• 1 PTC thermal sensor 
• 1 digital input.

Caution

Lack of oil may cause overheating and damage of 
the mechanical shaft seals. The WIO sensor in 
the oil chamber will trip the alarm if the oil quality 
is poor or there is not enough oil in the oil 
chamber.

Note

Note

The sensor signal is only valid when oil and 
water is mixed (when the pump is running).
