STEP SEVEN: Operation Screen
Vessel 2 is drying the inlet air (Vessel 2 inlet valve “K2” should
be open).
Vessel 1 inlet is preparing for regeneration.
Control system energizes SOL1 which closes Vessel 1 inlet valve
“K1.”
The regeneration valves K3 and K4 along with depressurization
valves V1 and V2 should be in the closed position.

on the screen once the Step is complete. If everything has been
verified in the step, press the “Proceed” button to proceed to

not fall below 8 PSI within 240 seconds, an alarm will pop up
and the system will halt until the problem has been corrected.
The regeneration valves K3 and K4 along with Depressurization
valve V2 and inlet valve K1 should be closed.
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.
