8. Faults; causes and corrections
Breakdowns can only be corrected by a qualified person! Before each
reparation, lower the cabin and unload if possible!
Turn off the main switch and unplug the machine before any intervention to the
electrical system of the elevator. Immediately cease operation in case of
breakdowns putting at risk the safety of platform operation!
In case of breakdowns or defects, check the following points:
•
Is the main power supply connected? Check all power boxes.
•
Is the main switch of the ground box (
GC1
) switched on?
•
Is the key switch on the main control panel (
CC1
) switched on?
•
Fuse/selector of the ground box.
•
Extension cable in working order?
•
Are emergency stop buttons?
•
Are the tailgates (loading, unloading installation) well closed?
•
Emergency travel end triggered?
•
Cabin moved too high or too low along the mast?
•
Are the travel end switches HIGH and DOWN working correctly?
•
Is the emergency centrifugal brake triggered?
•
Check the automatic disconnect switch in the ground box (
GC1
).
•
Is the selector key switch on the platform control system positioned for the desired operation
mode?
•
Is the red indicator light of the cabin control box turned on? (Cabin overload) (
optional load
cell
)
If the engine does not give full power:
•
Decrease voltage by more than 10% of the nominal voltage.
•
Change the power cable by a cable of greater diameter.
•
(
Optional load cell
) In case of overload, the integrated thermal switch turns off the current
control. A rapidly blinking light indicator on the cabin control box warns against the
overheating of the cabin engines. Work may be resumed after a cooling period (it is strongly
suggested to reduce the load.)
WARNING!
Repeated overheatings/overloads must be avoided, otherwise the lifespans of the engine and
engine brake are considerably reduced.
