ELECTRIC C301 - DIAGNOSTICS & TROUBLESHOOTING
The machine controller detects a wide variety of faults or errors.
Diagnosc informaon can be obtained on the 3100R fuel gauge display where an error code in the format ''Err ##''.
The troubleshoong chart below describes the Error code faults and their possible causes.
Whenever a fault is encountered the rst acon should be to turn o the ignion and push in the E stop buon. Then pull out the E stop buon and turn the ignion back
on to see if the fault clears. This is the RESET procedure:.
If the Error code does not clear aer the machine RESET, turn o the ignion switch and remove the 35-pin connector. Check the connector for correcon or damage,
clean it if necessary, and reinsert it.
If the Error is sll seen then the wiring and connecons on the machine should be checked for breakages or loose connecons.
The table below should be used as a reference once the above checks have been carried out.

HW
Fail-safe
Motor fault voltage (hardware failure)
1. Motor voltage does not correspond to throle
request.
2. Short in motor or In motor wiring.

Main brake driver over
current
Short circuit or overloaded controller driver, Early
controllers were re-programmed
15
Main
Current dropped
Main contractor failed open. 1. Clean the contactor switch TB10001
17
Main
Contactor Welded
Main contractor on fault 1. Main contactor failed closed, replace contactor.

Supervisor DIR Check
Fault
If fault is on an external signal, check that
signal rst. If no problem with the external
signal, likely indicates an internal controller
fault.
Early controllers were re-programmed
34 External Supply Fault Under voltage
1. Check control wiring circuit, potenometer wiring in
parcular.
TB10010
36
EM-Brake Driver
Open Drain
Hold voltage is set at 90%
1. Check bullet connectors to brake, check connuity or
2. The motor brake has failed.
54 Pre-charged Failed Pre-charge fault
1. Low baery voltage - 25V (11/12V) is good
condion, 22V (9/10V) or lower is bad baeries
condion.
2. Short circuit on tracon motor outputs.

HPD
Sequencing
HPD fault present > 10 seconds
1. Misadjusted throle
2. Broken throle potenometer or throle
mechanism.
TB10004
92 Motor Open Tracon motor not connected.
Controller can not see the motor.
Could be a short circuit in the motor.
1. Check the resistance across the motor leads.
99 Under-voltage Cutback Baery voltage too low
Baery voltage < undervoltage threshold.
1. Bad connecon at baery or controller.
2. Check no corrosion on the baery terminals.
Quick checks if no reading on fuel gauge and machine does not operate:
1. Check 10A fuse in the control panel. Fuse holder is located to the right hand side of the main control panel, turn CCW to release the fuse holder.
2. Check main fuse located behind the rear motor housing cover & 100A fuse. Open the rear cover which is xed in posion with 2 x M6 screws, ensure the cover is
supported during this process. Main fuse is located on the le hand side of the baery housing.
When changing the 100 amp fuse, ensure that the posive baery lead is fully dis-connected. Electrical maintenance should be carried out by a qualied person.
To maximize the life of your AGM baery, it is important that it is
properly charged. As with all lead-acid baeries, both over- and under-
charging an AGM baery will result in shortened service life.
The C301 mini dumpers are ed with an on-board SMART charger
which maintains the baery full charge condion without resulng in
over charging.
The AGM baeries are sealed for life units and do not require any uid
top up.
Please read the following instrucons:
Charging system Inspecon
The charger’s AC (mains) cord should be free of breaks or cuts and the
wall plug socket should be clean and free from debris.
The cable connectors from the on-board charger should be clean and
properly mate with the baery terminals to ensure a sound connecon.
Baery Inspecon
• Check baery cables are not damaged.
• Connectors should be free of corrosion.
• DC Cable post or eyelet connectors are ght to avoid arcing.
Charging Guidelines
• Fully charge baeries aer baeries have been dis-charged to ¼ full on baery
gauge. The on-board charger mains cord should be plugged into the mains AC
supply. Leave baeries to complete full charge and do not disconnect unl fully
charged. Once fully charged the on-board SMART baery charger will maintain
the baery fully charged status.
• Do not opportunity charge baeries i.e. if the baeries have only dis-charged
to ¾ full on the baery gauge, there is no need to connect the charger to the
AC supply. It is recommended to use the C301 unl the baeries have dis-
charged to ¼ full on the baery gauge, then place the C301 onto a full charge
cycle.
• Charge in a venlated area as gasses may be released through the pressure
relief valve if the baeries are excessively over-charged.
• Never charge a frozen baery.
• Ideal charging temperatures: (0°C to 40°C) 32°F to 104°F
