Configuring load-dependent mode
In load-dependent mode all cooling stages are activated if the load current of
the transformer is greater than the set switching point. You can set the
switching point as a percentage in relation to the transformer rated current.
Once the switch-on delay has elapsed, the cooling stages are activated. To
limit the switch-on current of the cooling stages, they are activated one after
another with a delay time of 60 seconds.
The following parameters are available to configure the load-dependent
mode:
▪
Activate load-dependent mode
▪
Switching point: Switch-on threshold as percentage, in relation to rated
current of transformer.
▪
Switch-on delay: Delay time for switching on the first cooling stage.
▪
Overrun: Period for which the cooling stages remain switched on if the
transformer load current is again less than the set switching point.
