5.12 Oil­temperature monitoring
Depending on the order specification, the gear unit may be fitted with a Pt 100 resistance thermometer for
monitoring the oil temperature in the sump. In order to measure the temperatures or temperature
differences, the Pt 100 resistance thermometer should be connected to a suitable instrument provided by
the customer. The thermometer has a connection head (protection type IP54) for the wiring.
A two­conductor circuit is provided by the manufacturer. However, the customer may fit his own three­ or
four­conductor circuit if required.
For control information, refer to the list of equipment.
Observe the operating instructions relating to the device in all instances.
