When the device is turned on
, this control system carries out a complete self-test cycle over the hardware and
the software (all the Led and displays light up, and the loudspeaker is activated). If everything works properly, this
phase ends by a short acoustic signal.
If the system detects any problem, the faults are indicated as described above, and the operator must either try to
eliminate all the possible causes, or switch the equipment off and ask for a technical assistance.
When the device is running
, this control system checks the functioning of the unit, included the output powers
(2000 times per second), by repeating the complete test on the functioning every 20 minutes (in an activation
interval).
Even in this case, the problems are indicated as described above
(“
When the device is turned on
”).
Control of the Error Codes
The unit stores the last 32 Error Codes that have been detected, in order to help the operators in finding a
solution for the problems/faults. The procedure to follow for this control is detailed into the Service Manual.
Inside the E

PROM hexadecimal value corresponding to one of error codes reported on “Error code” column in the
above table are stored.

Codes for Wrong Use or Activation Circuits Fault
For all the “

problems, the operators can act by eliminating the cause of the intervention of the self-diagnosis system.
In all the other cases, ask for the technical assistance, after having checked the signal by switching off and on the unit
