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.
