Dryer Operations

System display shows the dryer operations and provides the user the ability to change certain dryer settings. Review the 

following menu screens for navigation.

The step screens allow the user to view each step of the process. To navigate from this screen, press the “Screen Unlock” 

button then press the “Main Menu” button.
If in service mode, the “Proceed to Next Step” will be displayed on the screen once the Step is complete. If everything has 

been verified in the step, press the “Proceed” button to proceed to next step. This will allow an authorized service technician 

to view operation of the system in a shorter time period.

WARNING: 

If the screen is unlocked, the screen will not advance nor will the “Press to Proceed” button appear when the step 

is complete.

STEP ONE: Select Vessel 2 for Regeneration Running/

Operation Screen

Vessel 2 is preparing for regeneration. Control system energizes 

Solenoid SOL2, which closes Vessel 2 inlet valve “K2.”
Vessel 1 is drying the inlet air (Vessel 1 inlet valve “K1” should 

be open and solenoid SOL1 should be energized). The 

regeneration valves K3, K4, depressurization valves V1, V2 and 

re-pressurization valve V3 should all be closed.

STEP TWO: Vessel 2 Depressurization Running/Operation 

Screen

Vessel 2 is preparing for regeneration.
The PLC control system energizes solenoid SOL4 to open the 

depressurization valve “V2” which depressurizes Vessel 2. If 

the pressure in Vessel 2 does not fall below 8 PSI within 240 

seconds, an alarm will pop up and the system will halt until the 

problem has been corrected.
Vessel 1 is drying the inlet air (Vessel 1 inlet valve “K1” should 

be open and solenoid SOL1 should be energized). Inlet valve 

K2, regeneration valves K3, K4, depressurization valve V1 AND 

re-pressurization valve V3 should all be closed.
