POSSIBLE CAUSE
This is just a warning when a lifting/low-
ering request is active at key-on.
When the key is turned ON, the control-
ler checks the battery voltage and veri-
fies it is within a window around the
nominal value.
This alarm occurs when the procedure
for the maximum current set-up is in
progress.
This is just a warning to perform pro-
grammed maintenance.
FAULT CLEARANCE
The possible reasons for this alarm are
(use the readings in the TESTER to
facilitate the troubleshooting):
• When MDI-PRC is absent: at least on
between LIFTING SWITCH (CNB#9)
or DESCENT SWITCH
active at key on.
• When vehicle TYPE is Level=1: at
lease one between: LIFTING SWITCH
(CNB#9) or DESCENT
(CNB#8), DIGITAL
(CNA#14) or DIGITAL
(CNA#15) active at key on.
• When vehicle TYPE is Level=2: at
lease one between: LIFTING SWITCH
(CNB#9) or DESCENT
(CNB#8) active at key on.
• When vehicle TYPE is Level=3: at
least one between LIFTING SWITCH
(CNB#9) or DECENT
(CNB#8) active at key-on.
A failure in the logic is possible too.
When all of the above conditions were
checked and nothing was found, replace
the controller.
Replace the battery.
The maximum current set-up is factory
adjusted and so this alarm should
never happen. So ask for the assis-
tance of a Big Lift LLC Service Repre-
sentative when this alarm occurs.
It is just enough to turn the CHECK UP
DONE option to level ON after the
maintenance is executed.
