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 18).
•
The Valve Inputs are listed in F
•
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
(Yellow Tube 1/4 in.OD)]. Connect each Quick Dis-
connect (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)
