How it Works:
The remote wand operates on a 12-volt DC circuit. When the engine is
started, hydraulic pressure from the manifold (A) is sent to the valve-actuating cylinder (B)
through lower hose (C). The cylinder will extend fully and
CLOSES
the sealing hose valve to
stop material flow to the hose.
When the trigger switch handle (D) is depressed, 12-volts is sent to the manifold cartridge (E).
The cartridge opens and sends oil to hose (F) and at the same time, allows oil in the other line
to return to tank. This retracts the cylinder and
OPENS
the sealing hose valve so material can
flow to the hose. As soon as the switch is released, the 12-volt current is removed and the
cylinder extends and closes the sealing hose valve.
12-volt power runs from the remote sealing wand switch (G) to the switch located under handle
(D). The wire then runs back to the manifold cartridge (E). When the switch is activated, the
two wires connect and send 12-volts to the cartridge.
There is a 10-amp fuse inside the control box to protect this circuit.
Troubleshooting:
If the hydraulic cylinder does not respond when the trigger is activated, one
of the following items may be the cause.
1) Bad trigger switch
2) Unresponsive solenoid at the hydraulic manifold
3) Clogged hydraulic line
4) Broken or disconnected wire in the electric hose or at the switch
5) Blown fuse or a bad switch in the control box
6) Defective cylinder –bad seals or bent rod
7) Binding or frozen sealing hose valve or linkage
8) Bad ground connection on the cartridge
The best place to start looking for the problem is the power source. Check the 10-amp fuse
(orange wire, see decal inside temp control). If it is good, use a power tester to see if you have
voltage to and from switch (G). If you do, check to see if you have voltage at one of the termi-
nals at the trigger switch. If you don’t, there is a broken or loose wire between the control panel
switch and the trigger switch on the wand.
If you have 12-volts to the trigger switch, depress the trigger and you should send 12-volts to
the cartridge (E) at the hydraulic manifold, which in turn will activate the cylinder (B). An easy
way to check to see if the solenoid is getting current is to put your hand on the solenoid and
see if you can feel it click each time you depress the trigger switch. If it does not click and you
are sure you have power, it may be defective. You may also “hot wire” the cartridge by running
a jumper wire from any 12-volt source directly to the wire coming from the cartridge to see if it
is working properly.
