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.

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.
