ERROR ERROR TEXT POSSIBLE CAUSE FAULT CLEARANCE
91 LIFT LOW ACTIVE This is just a warning when a lifting/low-
ering request is active at key-on.
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 (CNB#8)
active at key on.
• When vehicle TYPE is Level=1: at
lease one between: LIFTING SWITCH
(CNB#9) or DESCENT SWICH
(CNB#8),
DIGITAL INPUT#1
(CNA#14) or DIGITAL INPUT#2
(CNA#15) active at key on.
• When vehicle TYPE is Level=2: at
lease one between: LIFTING SWITCH
(CNB#9) or DESCENT SWICH
(CNB#8) active at key on.
• When vehicle TYPE is Level=3: at
least one between LIFTING SWITCH
(CNB#9)
or DECENT SWITCH
(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.
93 WRONG SET BAT. 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.
Replace the battery.
94 CURRENT SENS KO This alarm occurs when the procedure
for the maximum current set-up is in
progress.
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.
99 CHECK UP NEEDED This is just a warning to perform pro-
grammed maintenance.
It is just enough to turn the CHECK UP
DONE option to level ON after the
maintenance is executed.
