Automatic restart after voltage failure
The regulator has a built-in function to automatically restart the dryer if the voltage is restored
after voltage failure. For dryers leaving the factory, this function is not activated. If desired, the
function can be activated. Consult the Customer Centre.
If activated and provided the regulator was in the automatic operation mode, the dryer
will automatically restart if the supply voltage to the module is restored within a
programmed time period.
The power recovery time (the period within which the voltage must be restored to have
an automatic restart) can be set between 15 and 3600 seconds or to ‘Infinite’. If the
power recovery time is set to ‘Infinite’, the dryer will always restart after a voltage failure,
no matter how long it takes to restore the voltage. A restart delay can also be
programmed, allowing for example the dryer and the compressors to be restarted one
after the other.
