Load-dependent mode: Overrun time
You can use this parameter to set the time period for which the cooling
stages remain switched on when the transformer load current returns to a
value below the set switching point.
9.11.5 Configuring periodic mode
Periodic mode is used to prevent the bearings of the cooling stages from
seizing up as a result of long idle periods. To do this, the cooling stages are
operated for a certain period at regular intervals regardless of the measured
temperature. You can activate/deactivate periodic mode individually for ev-
ery cooling stage (Configuring cooling stages [►Section 9.11.1, Page 153]).
