Page 5: Structure
Structure Operating principle Structure An oil heater is required to allow for a smooth start-up in the event of a cold start at low ambient temperatures. The oil heater is available with an external or an integrated thermostat depending on the gear unit design. However, a gear unit heater is only possible for mounting positions where the thermo- stat and the screw-in heater are sufficiently covered with oil. -
Page 6: External Thermostat
Structure External thermostat The thermostat has to be energized continuously, even if the drive is at a brief stand- still. If the drive is at standstill over a longer period, for example during holidays, and the thermostat is not energized, you have to make sure that the thermostat is ener- gized in due time before the drive is started up. -
