V12 PPVS PUMP OVERIDE VALVE

In the on position, allows the gun return signal to pass and activate PUMP SIGNAL VALVE (V09).

Triggered by OR11
V13 SP4 TANK SUPPLY VALVE

In the on position, supplies the SP4 with pressure to start the flush sequence.

In the off position, vents SP4 to allow it to refill

Triggered by FLUSH CYCLE SIGNALS VALVE (V10).
Note: When in the off position this valve vents outside cabinet. This prevents an SP4 failure from backing solvent up into the internal air
supply.
V14 MPG GUN OVERIDE

In the on position, supplies GUN PPVS VALVE (V08)

Triggered by MPG LOW PRESSURE RELAY VALVE (S02).

This is a maintained circuit. Once the MPG starts to vent, it will release pressure on the signals to V14, V15 and the piloted regulator.
This in turn will decrease the pump output pressure via piloted regulator. Once the pressure has reached a low set point, the MPG LOW
PRESSURE RELAY VALVE (S02) will close and shut off V14 and V15 until the output pressure of the MPG has decreased to a safe
value, then the injection cycle will resume.
V15 MPG PUMP OVERIDE

In the on position, pilots MAC valve on pump power head.

Triggered by MPG LOW PRESSURE RELAY VALVE (S02).

This is a maintained circuit. Once the MPG starts to vent, it will release pressure on the signals to V14, V15 and the piloted regulator.
This in turn will decrease the pump output pressure via piloted regulator. Once the pressure has reached a low set point, the MPG LOW
PRESSURE RELAY VALVE (S02) will close and shut off V14 and V15 until the output pressure of the MPG has decreased to a safe
value, then the injection cycle will resume.
V16 IVx3 FLUSH SIGNAL

In the on position, pilots IVx3 to move into the flush position of the valve. This valve remains open upon completion of the flush cycle to
allow the plunger to remain in the down position on the valve. Once the injection cycle is started the valve is reset.

In the off position, removes the flush signal for the IVx3 valve

Triggered by FLUSH CYCLE SIGNALS VALVE (V10).
