7.4 SM 113, optional
SM 113 is designed and used for the collection and transfer of
additional sensor data. SM 113 works together with IO 113 with
communication module, product number 98097390, as shown in
the figure below.

IO 113 and SM 113
SM 113 can collect data from these devices:
• current sensors, 4-20 mA*
• Pt100** thermal sensors.
* Vibration sensor (FPV)
** Maximum three Pt100 sensors.
7.5 Switches and sensors
Install an additional level switch to ensure that the pump is
stopped in case the primary stop level switch is not operating.
A pump includes the following switches and sensors:
• three thermal switches or three thermal protectors in the stator
windings
• moisture switches:
– in range 50-70: one under the motor top cover
– in Ex pumps, range 50-58 and 70: one under the motor top
cover and one in the stator housing
– in Ex pump, range 62: two under the motor top cover.
• one optional Pt100 sensor in the bearing or in the stator
winding
• one analog and optional WIO sensor in the oil chamber.
