Thermal motor protection using PTC thermistors (option)
The machine is equipped with PTC thermistors for direct monitoring of the motor temperature
to protect the machine against overheating during operation. Plan a corresponding circuit for
monitoring.
4.9
Interlock circuit for the automatic regreasing system (option)
Relubrication is permitted only for a rotating shaft. Consequently, deploy an interlock circuit for
machines with automatic regreasing system to prevent them from operating at machine
standstill.

If the anti-condensation heating is operated while the machine is running, this can increase the
temperatures inside the machine.
● Install an interlock circuit that switches off the anti-condensation heating once the main
● Only switch on the anti-condensation heating after the machine has been switched off.
