ENGINE MALFUNCTIONS
The electronic unit overseeing management and control of all
operation of the engine is capable of recognising any malfunctions that
may occur, and of adopting strategies that will allow you to proceed
in full safety.
The event, signalled by light-up of the EDC MALFUNCTION indicator
on the on-board control panels, results in programmed limitation of
power within certain thresholds, set according to the severity of the
case.
In the case of temporary malfunctions the reduction in performance
will remain in force until the engine is stopped.
BEHAVIOUR IN CASE OF FAILURE
Accelerator electronic circuit malfunction
When certain problems in the accelerator electric circuit are
recognised, the Electronic Unit controlling the engine adopts a strategy
known as “accelerated minimum speed running”, that will enable
running/work to continue in emergency mode.
The possible operating modes are as follows:
A. The accelerator lever does not “respond”: the running speed
stabilises at 750 rpm. to allow the machine to proceed slowly and
be manouevered simply by turning the inverter on and off,
without accelerating.
B. The accelerator lever “responds partially”: the minimum running
speed is set to 750 rpm. When the accelerator lever is moved to
approximately half way, the speed gradually increases up to 2000
rpm.; when the lever is returned to minimum the speed rapidly
decreases to 750 rpm.
Malfunction in the recharging system
The Electronic engine control units are programmed to increase the
minimum running speed if the voltage in the electrical system reaches
values considered to be at the limits of efficiency. In this case, check
the efficiency of the battery/ies and if necessary perform a check-up on
the system components.
CAUTION!
The engine electronic control unit can adopt safety
strategies at any time during use of the machine or
vehicle, should conditions arise that are considered to put
the engine at risk.
When conditions of this kind occur, proceed only if
necessary and with the greatest possible care and
attention.
CAUTION!
Do not leave vehicles or machines with the engine running
without first putting the parking lock or brake on.
