Energized To Close

The NXT Stager control can operate an optional 24 VAC

solenoid to control when a tank is off line. This solenoid is

electrically connected to the "lower drive" connection on the

circuit board, and control pressure is run through the solenoid

to the service outlet diaphragm valve.

The solenoid installed at the factory is a universal type. It is

plumbed in an energize to close configuration when service

outlet valve is normally open.

When a tank enters Regeneration or Standby the solenoid is

energized. Pressure from solenoid port 1 passes to port 2.

The diaphragm valve #2 will close.

When a tank enters In Service the solenoid is de-energized.

The inlet pressure to solenoid port 2 is stopped. The

diaphragm valve is vented through solenoid port 2 to port 3

(drain). The valve #2 opens.

Inverted Stagers Only - Energize to Open

If the service outlet vavle is normally closed, connect constant

pressure source to solenoid port 3. Connect solenoid port 2 to

service outlet valve. Solenoid port 1 is drain.
