Airlogic graphic regulator

3.1 Airlogic graphic regulator
Control panel
The Airlogic regulator automatically controls and protects the dryer, i.e.:
 keeping the pressure dew-point stable.
 monitoring pressures, temperatures and digital switches to ensure safe operation, and stopping the dryer
whenever necessary.
 Restarting the dryer when required.
In order to control the dryer and to read and modify programmable parameters, the regulator has a
control panel provided with:
 LEDs indicating the status of the dryer.
 a display indicating the operating conditions or a fault.
 keys to control the dryer and to access the data collected by the regulator.
 buttons to manually start and stop the dryer.
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.
28
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.
