12. TROUBLE SHOOTING
12.1 General information.
In case of a problem the unit will produce an error code. Intermittent error codes can be recovered by
means of the service software, which gives an overview of the last 10 error codes.
If the error code is generated during the self test, and the cause of the problem is difficult to detect,
there is a possibility to deactivate the control of the safety relay and skip the self test.
In order to deactivate the control of the safety relay, both the jumpers of CON 3 on the main PCB
must be put from position ‘OPERATE’ to position ‘SERVICE’. Putting the jumpers into ‘SERVICE’
position will avoid that the safety relay can be switched off.
Since the functioning of the safety relay is tested during the selftest, it will generate an error code
when the unit is in ‘SERVICE’ mode.
Therefore the selftest must be bypassed. This can be done by putting a jumper on CON 9 (factory
mode).
After both the ‘SERVICE’ jumper and the factory jumper are changed, the unit can be powered up
without performing a selftest and without the possibility to deactivate the safety relay.
/ It is very important that after repairing the unit, the unit will be reset to ‘OPERATE’ and the
factory jumper is removed before the unit will be used to treat a patient. Not following this
instruction can bring the safety of the patient and the therapist is jeopardy.
In case the service engineer cannot solve the problem, it is recommended to communicate the
problem with the GymnaUniphy nv. service department.
In order to communicate the problem the most efficient way, a special error registration document
must be used.
Fill out the service form as complete as possible. Our service department will evaluate the call and
propose further steps in order to solve the problem.
