15.0 PROCEDURE OF TROUBLE SHOOTING.
15.1 SOLENOID
VALVES.
When checking if the Solenoid valves are receiving electric power, you do this in the following
way:
1.
Unscrew the nut that holds the solenoid.
2.
The solenoid is easy to move without electric power.
3.
Push the current function on the remote control. If the solenoid gets power, it will be
difficult to move, it "sticks". This is the best and easiest way to check if the solenoid valve
is receiving electric power. Another way is to hold a screwdriver up to the magnet. If it
"sticks", the solenoid is receiving electric power.
The power supply to the valve can also be measured with a voltmeter, but then the contact must
be connected to the solenoid, so it is using power.
To have reliable functions, the voltage should not be lower than 11,5 volts, even if the solenoid
valve usually works with a little lower voltage.
15.2
Only for solenoid valves to the main functions.
If the electric supply is in order and one of the functions fails, the reason can be dirt that tightens
or prevents the sliding shaft (spool) from moving.
Try to maneuver the function manually, by pressing the point of a screwdriver into the end of the
valve housing.
At the same time the corresponding switch on the control unit has to be
operated to get electric power to the master valve.
If the function is working again after this,
the dirt may have been pushed out in the oil system and the machine can be operated normally
again.
Take care so that the machines moving parts, do not cause damage to persons
or objects.
