V03 CATAYLST OVERPRESSURE VALVE

In the on position, supplies the catalyst overpressure circuit.
 In the off position, pilots INJECTION SEQUENCE START VALVE (V02) and FLUSH INTERLOCK VALVE (V05), stopping the
injection or flush sequence.
 Triggered by CATAYLST OVER PRESSURE VALVE (S04).
V04 NOT USED
V05 RECIRCULATION/FLUSH INTERLOCK VALVE
 In the on position, enables FLUSH PUSHBUTTON (PB08), supplies RECIRCULATION PUSHBUTTON (PB09) and signals AN01,
allowing the injection button to be used.
 In the off position, disables FLUSH PUSHBUTTON (PB08), and RECIRCULATION PUSHBUTTON (PB09).

Triggered by REMOTE STOP PUSHBUTTON (PB03) or STOP PUSHBUTTON (PB06) or CE NORM GUARD INTERLOCK (S03) or
CATAYLST OVERPRESSURE VALVE (V03) or E STOP (PB07)
V06 INJECTION GUN VALVE

In the on position opens injection gun (Pro and RAV) and also enables the MOLD PRESSURE GUARD PUMP VALVE (V15). MOLD
PRESSURE GURARD GUN VALVE (V14) and GUN PPVS VAVLE (V08) signals must be present for this circuit to complete.

In the off position closes injection gun (Pro) and supplies MOLD PRESSURE GUARD PUMP VALVE (V15).

Triggered by the GUN PPVS VALVE (V08) or (PB05)
V07 RECIRCULATION GUN VALVE
 In the on position opens recirculation gun (Pro) and also pilots the PUMP SIGNAL VALVE (V09).

In the off position closes recirculation gun (Pro).
 Triggered by RECIRCULATION PUSH BUTTON (PB09)
V08 GUN PPVS VALVE
 In the on position pilots INJECTION GUN VALVE (V06)

Trigged by PPVS sensor (external).
V09 PUMP SIGNAL VALVE
 In the on position supplies MOLD PRESSURE GUARD PUMP VALVE (V15). MOLD PRESSURE GUARD PUMP VALVE (V15)
must have a signal to start the pump
 Triggered by INJECTION GUN VALVE (V06) or PPVS PUMP OVERIDE VALVE.
V10 FLUSH CYCLE SIGNALS VALVE

In the on position pilots SP4 TANK SUPPLY VALVE (V13), Ix3 FLUSH SIGNAL (V16), SP4 QUICK EXHAUST AND GUN HEAD
FLUSH BUTTON.

In the off position pilots FLUSH TIMER CIRCUIT VALVE (V11), fills the FLUSH TIMER RESIVOIR and supplies a signal to AN1

Triggered by FLUSH PUSHBUTTON (PB08).
V11 FLUSH TIMER CIRCUIT VALVE

This is a latching valve. Once FLUSH PUSHBUTTON (PB08) is pushed, the signal will slowly vent from the FLUSH TIMER
RESIVOIR and reset the valve. FC05 in this circuit is used to adjust the dwell of the flush cycle.
