Once the main air valve and closed loop regeneration valve are in place, the process air blower starts. The system monitors the process air blower’s overload, starter auxiliary contact feedback and air pressure. Loss of any of these items when the process air blower is running will cause the process air blower and the drying hopper’s process heaters to shut down.

The process air heaters (or gas burners, on gas-fired dryers) will turn on after a delay to allow the process air blower to accelerate the operating speed.

During normal operation, one set of desiccant beds is connected to the process air circuit while the other set is being regenerated. When the offline beds are done regenerating, they will be switched into the process air circuit and the other beds will be regenerated. The default bed switch setting is based on time. If the Dewpoint Switch option is enabled, the beds will switch when the process air dewpoint reaches the dewpoint switch point. The dewpoint option will automatically disable itself and an alarm will be generated if the dewpoint sensor or related electronics fail.

2-3 Standard Features

Auto Start Timer

The autostart timer is used to automatically start and stop the dryer at the time you specify. It can be programmed for one start and/or stop event per day for a week. When the Auto Start Timer is enabled, the dryer will automatically start and stop at pre-programmed times. If the dryer is stopped due to the Auto Start Timer, the DRYER STATUS message will indicate that the Auto Start timer is active.
