The following table shows the number of diagnostic LED flashes and the corresponding errors:
No. of flashes
Description
1
Motor not at a stop upon start
2
Motor not at a stop upon start
3
Battery voltage too low
4
Battery voltage too high
5
Potentiometer not at zero setting upon start
6
Potentiometer cutout
7
Overtemperature
9
Eeprom programming error
10
Control power error
Electronic system by Energy
:
1 flash
Anomaly to traction micro-switches at the start. It signals that one of the traction
micro-switches is already active at the start
2 flashes
Battery voltage too low, not enough for a correct use of the machine
3 flashes
Inactive code
4 flashes
Open motor circuit
5 flashes
Motor control failure or earthling motor fail
6 flashes
Anomaly to the potentiometer. This alarm is not working with 2-wire
potentiometers
7 flashes
Overheated mosfets, this alarm is activated when the temperature gets to 75°C
+/- 5°C. This alarm is on until the temperature is high and reduces the maximum
motor current
8 flashes
Motor already running at machine start. Example: controller switching on when
going down from a slope
9 flashes
Software anomaly
Only for machine with Energy control card: when the direction selector is released with the
machine going backward, the scrubber goes a little bit forward in order to avoid any risk of
crushing
In order to limit the likelihood of electronic board failures, the following points should be observed:
It is strictly forbidden to disconnect the battery during running operation;
It is strictly forbidden to turn the key switch off and then back on during machine operation;
Do not operate the key switch while pushing the machine manually or going downhill;
Check that the key switch electrical contact is perfectly efficient to prevent bounces or false
contacts;
Check that the contact between connectors is steady; check that power connections are
tight and use deoxidizer spray between connectors;
It is forbidden to leave the key switch on during battery charging;
During cleaning operations, disconnect the battery; never wash the electronic board with
water and solvents, avoid pressurised jets and before restarting the machine, ensure that it
is perfectly dry.
