2.5 Motor protection
The pump motor has a locked thermal winding protection as over
-
load protection. In the event of excessive temperature or if the
motor is blocked, the vacuum pump switches off.
If the vacuum pump is switched off due to these safety precau-
tions, the error must be cleared manually: Unplug pumping unit
from power supply ‑> eliminate cause of error ‑> after a waiting
time of ca. 5 minutes switch pumping unit back on.
CAUTION
Limited winding protection in the case of supply
voltages less than 100 V.
In the case of supply voltages less than 100 V, the self‑
retention of the winding protection may be limited such
that the pump may automatically start up after cooling.
