Optional Cycle Detection Sensors
332089B 7
Optional Cycle Detection
Sensors
The sensors are magnetic reed switches and must be
connected to an electrical control package. The sensors
wires are #24 awg and have 9 foot (2.7 meters) flying
leads. An LED on the sensor illuminates to indicate a
change in state.
Suggested Sequence of Operation (See
page 16).
• The Valve Inputs are listed in FIG. 9, page 22.
• The Valve Outputs (supplied by others) consisting of
two power valves or one dual power valve [Sole-
noid-Close Spool Valve/RETract (Green Tube 1/4 in.
OD) and Solenoid-Open Spool Valve/EXTend (Yel-
low Tube 1/4 in.OD)]. Connect each Quick Discon-
nect (5/16-24 fitting) to respective power valve port.
• Other needed Input would include some type of
Start device (Foot Switch or Control Box) (supplied
by others)
1. Home (Reload) Position
a. Solenoid-Close Spool Valve/RETract is acti-
vated.
b. Solenoid-Open Spool Valve/EXTend is deacti-
vated.
c. PX-EXT and PX-CSV signal have been made.
d. PX-RET and PX-OSV signal is not made.
e. Metering Rod is Retracted.
2. Shot Procedure
a. Start device signal is made.
b. Solenoid-Close Spool Valve/RETract is deacti-
vated.
c. Solenoid-Open Spool Valve/EXTend is acti-
vated.
d. PX-EXT and PX-CSV signal drops off.
e. Spool shifts from the Reload Position to the Dis-
pense Position.
f. PX-OSV signal is made.
g. Metering Rod Extends downward (Dispensing
Material).
h. PX-RET signal is made and Metering Rod is
down (Dispense Material Complete).
i. Solenoid-Open Spool Valve/EXTend is deacti-
vated.
j. Solenoid-Close Spool Valve/RETract is acti-
vated.
k. PX-OSV signal drops Spool shifts from the Dis-
pense Position to the Reload Position and
Metering Rod Retracts upward (Reloading
Material).
l. PX-CSV signal is made.
m. PX-EXT signal is made.
n. Dispense Valve is ready for next Start device
signal.
