LOGIC
FAILURE #1
This fault is displayed w hen the
controller detects an undervoltage
condition at the KEY input.
Undervoltage threshold depends
on the nominal voltage of the
controller
1-Fault can be caused by a key input
signal characterized by pulses below
the undervoltage threshold, possibly
due to external loads like DC/DC
converters starting-up, relays or
contactors during switching periods,
solenoids energizing or
de-energizing. Consider to remove
such loads.
2-If no voltage transient is detected
on the supply line and the alarm is
present every time the key switches
on, the failure probably lies in the
controller hardware. Replace the logic
board.
3-If the alarm occurs during motor
acceleration or when there is a
hydraulic-related request, check the
battery charge, the battery health and
power-cable connections.
