After a preset period, (or when triggered by the PDP sensor), the function of the towers is
reversed. The fully regenerated tower will now dry the air, while the desiccant in the other tower
will be regenerated.
By default, the regeneration timer will restart from the beginning of the cycle in case of a power
failure during operation or in case the dryer was switched off.
The working sequence of the controller is the following:
Status Left vessel Right vessel V1 V2 V3 V4
0 Stopped Stopped 0 0 0 0
1 Adsorbing Adsorbing 0 0 0 0
2 Shifting Adsorbing 1 0 0 0
3 Depressurizing Adsorbing 1 0 1 0
4 Regenerating Adsorbing 1 0 1 1
5 Equalizing Adsorbing 1 0 0 0
6 Freeze (compressor
synchronization) Adsorbing 1 0 0 0
7 Standby Adsorbing 1 0 0 0
8 Adsorbing Adsorbing 0 0 0 0
9 Adsorbing Shifting 0 1 0 0
10 Adsorbing Depressurizing 0 1 1 0
11 Adsorbing Regenerating 0 1 1 1
12 Adsorbing Equalizing 0 1 0 0
13 Adsorbing Freeze (compressor
synchronization) 0 1 0 0
14 Adsorbing Standby 0 1 0 0
When the ON/OFF push-button is pressed during operation, the controller jumps automatically to
status 5 or 12 (equalization phase). After that, the Stop status (0) will be reached. The following
start command will restart the sequence from the state 2 or 9. The same happens when the
power is switched off.
On dryers equipped with the
AirLogic²
controller, a so-called Freeze (compressor
synchronization) contact (X2) is available to stop the regeneration air flow when the connected
compressor is running unloaded. If this option is used, the controller jumps automatically to
status 5 or 12
(equalization phase). After this, the Freeze status (6 or 13) will be reached. Regeneration air flow
is stopped. When the Freeze contact opened, the cycle will restart from status 2 or 9.
Do not connect the Freeze contact (compressor synchronization contact) when an air
receiver is installed upstream of the dryer. The Freeze contact (X2) should only be
connected when the air receiver is installed downstream of the dryer. See also section
Installation proposal .
On compressors with an AirLogic² controller, the function PDP Extended Cycle can be activated.
See section
Modifying Settings . When this function is activated, the regeneration air flow stops
when the PDP is reached.
