PLEASE CONTACT YOUR DEALER IF YOU ARE IN DOUBT ABOUT ANYTHING.
(Remember always to give your dealer the serial number and production year of your machine when contacting dealer and when ordering spare parts).
Procedure of Troubleshooting
If the machine fails to operate correctly it must be determined if the problem is Hydraulic, Mechanical or Electrical.
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 receiv-
ing 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.
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 manoeuver 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.
The Machine Does not Function
- Even if the gauge shows enough pressure and there is no reaction in the machine. The reason could be that one, (or both), of the quick-couplers does not open for the oil, in this situa-
tion you should change the quick-couplers.
- The counter pressure may be too high.
Max. allowed counter pressure is 10 bar.
Make sure that the open / closed valve is correctly positioned.
Note: Disturbances of this type, a, b or c, are most likely in the first days that the machine is in use.
The Cutter will not Hold the Film
Is the cutter closing fully, if not increase the Cutter Close Duration 2.
If the cutter is creeping open, there may be dirt in the load holding, open and close the cutter a number of times to try to clear this. . If the problem develops over time then it may be due
to seal wear in the cutter arms.
