fault
When starting, controller checks battery voltage if it is
within the nominal range. Check if the “BATTERY
VOLTAGE” parameter in TESTER is the same
with the value shown on the voltmeter. If they are not
the same, adjust the battery voltage through
“ADJUST BATTERY” to be the same with measured
value.
Change the battery.

EEPROM KO Damage of
programmable
memorizer
Fault in the area of memory in which the adjustment
parameters are stored; this alarm inhibits machine
operation. If the defect persists when the key is
switched OFF and ON again, replace the logic. If the
alarm disappears, remember that the parameters stored
previously have been cancelled and replace by the
default values.
