Setting values for temperature monitoring (slot thermometer)

Before the first machine run, set the tripping temperatures of the monitoring system.
The tripping temperatures of winding thermometers differ depending on the temperature class
of the machine. The temperature class can be found on the rating plate.

Switching off the machine

● Do not switch off the water-cooling system immediately after switching off the machine.
7.11 Avoidance of condensation or formation of condensation within the
machine
● If the controller does not do this automatically, switch on any anti-condensation heating
● Observe the specifications on the anti-condensation heating plate in this regard.
