Maintenance
As with any piece of equipment, periodic maintenance will help provide longer life and trouble-free operation of your new
PoppetPLUS system. Periodically inspect those electrical connections which are exposed to the elements for signs of cor-
rosion or other damage. Replace any terminals that look as if they might fail in the eld. Inspect the cable connecting the
switch to the valve. Normal operation over time can cause a cable to move to a dangerous area. If the cable is in any danger
of being crushed or cut, move it to a safer area and secure it. Check the hydraulic hoses connected to the valve. Wipe the
body of the valve o and look for leaks. Tighten or replace any ttings you suspect of leaking. Inspect the hydraulic hoses for
signs of leaking, cracking or bulging. Replace any hoses that show signs of failure.
Troubleshooting
If the valve was previously working, the trouble is most likely the result of a blown fuse, damaged wiring or a bad switch. If this
is a new installation, carefully check the hydraulic connections to make sure that the valve is installed correctly as shown in the
diagram. Also, inspect hydraulic coupler tips for proper mating. Incompatible couplers will usually not allow the ball or poppet to
unseat properly and prevent a good hydraulic connection.
Electrical Troubleshooting
A simple way to determine if a solenoid is being energized is by touching the mounting nut on the valve coil with a screwdriver.
The coil is an electromagnetic part and will attract the screwdriver when the power is on. If the screwdriver does not stick to the
top of the coil, use a voltmeter to check for voltage between the coil terminal and the mounting nut. If the voltage is at least 11
volts, the valve should be functioning. When the coil is energized a click should be audible from the valve. The sound may be
quiet or mued if the valve is under pressure. If the voltage is low, check the voltage at the source where the power wire for the
control was connected. If no voltage is found, try measuring the voltage between the coil terminal and the tractor frame. If volt-
age is indicated, the valve is not being grounded. Check the black ground wire. If no voltage is indicated between the coil power
wire and the ground, rst check the fuse and then the red wire to the switch control box.
Hydraulic Troubleshooting
If none of the circuits work and the solenoid coils are being operated with at least 11 volts (measured at the coil), check that the
supply connections from the tractor remote to the valve are correct. Check that the cylinders are connected to the valve as shown
in the diagram. If necessary, remove the valve and connect the cylinder to the remote outlet to conrm that the supply hoses and
coupler tips are in working order.
Warning
To avoid serious injury or death:
• Use extreme care to make sure all individuals are safely clear from equipment and the nearby area whenever operating
remote valve control switches.
• Operating electrical controls (even when the remote lever is in neutral or the engine is stopped) will result in the valves
operating and may result in equipment moving suddenly without warning. Stay clear of all valves, lines, cylinders and
what cylinders operate when using the controls.
