REPLACING THE CONTROL UNIT

TRANSFER OF PROGRAMMING OPERATIONS

MEMORY

Press and

wait for

completion of the

transfer.

Check that the

memory

is inserted

correctly.

WARNING

THE TYPE AND REVISION

OF THE TWO CONTROL

UNITS MUST BE THE

SAME.

Before replacing the control unit, we advise transferring all the programming settings to the new control

unit; if this operation is not carried out, the new control unit will operate with the factory programming

settings. In this case, it is necessary to carry out programming of the current transformer.

PROCEDURE

TO BE CARRIED OUT WITH ENGINE STOPPED

AND CONTROL UNIT NOT POWERED

NEW CONTROL UNIT CONTROL UNIT TO BE REPLACED

Remove the

memory and

eliminate it

MEMORY

Supply power to the control unit

The following is read on the display

Repeat the procedure

It is possible to transfer the programming operations of a standard control unit onto several memories.

We advise you not to exceed fty transfers.

Example:

CONTROL UNIT A

(STANDARD) CONTROL UNITS B - C - D TO BE UPDATED

Remove the

memory

and insert it

in the new control

unit

If, during normal

operation, the

fault is activated

the memory is no

longer used.

PREVENTIVE MAINTENANCE

CHANGE RESETTING OPERATIONS

The control unit manages three xed time notications and a cyclic notication. Notications 1, 2 and 3 are for a xed

time and trigger only once, when the hour meter reaches the programmed value. Notication number 4 is cyclic and triggers after

the programmed hours and whole multiples of them. The request for maintenance is indicated: by the ashing of the hour meter,

the intermittent switching on of the yellow warning light and the message on the display.

Example 1: Notication 4 is programmed to 100. The notication triggers after 100, 200, 300, 400 ... hours.

Example 2: Notication 1 is programmed to 100. The notication triggers at 100 hours, and never triggers again.

The factory value for all the notications is zero. The maintenance operations are programmed by the G.S. manufacturer during

testing. The maximum value is 59999 hours.
