TROUBLE-SHOOTING
The heavy duty trolley’s electric system
consists of several interconnected compo-
nents, all of which are important so that the
daily operation can take place safely and
properly. In the event of operational disrup-
tions, the system is programmed to prevent
further driving in most cases. This is to en-
sure a high level of safety for the user and
the context in which the trolley is used.
The motor control has a built-in simple
diagnostic system for decoding the fault.
The diagnostic system communicates by
the status lamp (A) located in the tiller head
flashing in a sequential pattern. The pat
-
tern consists of a long pause, a number of
flashes, a short pause and another number
of flashes.
The sequence is repeated until the fault
has been rectified or the heavy duty trolley
is switched off via the key switch. The two
described number of flashes in the sequen
-
ce represent the first and second digits of
the error code. For example, the following
sequence • •••• will indicate error code
1.4. To rectify the fault, contact IMMO A/S
or your dealer. When contacting the dealer
or the manufacturer you will be asked to
inform the machine number, which is stated
on the machine plate located on the under-
side of the tiller head.
In fault-free condition where the heavy duty
trolley is ready to drive or is driving, the
status light is permanently on.
