Troubleshooting
The safety advice in this document must be followed before attempting to troubleshoot.
If charging does not start when commanded please follow the steps below:
1. If the Green AC Present LED is not lit
–
Check that input cable is securely inserted.
–
Check that the input voltage is within the WPU's operating range (85 V
disabled its output. Please check the following:
2. Charger system output.
–
–
Check the battery is connected to the WSU with the correct polarity.
–
Measure the battery voltage and check that it is within the acceptable range for the WSU
variant. See section 4.3.1 for the acceptable voltage ranges.
–
Check that the signal cables are connected securely to the vehicle controller.
–
–
Check that "Sleep Mode" is not active. Refer to section 6.3
3. Air gap and misalignment.
–
Check that the pad gap and alignment is within the acceptable range. Refer to section 4.5
4. CAN bus mode.
–
Check that the baud rate is correct. The default baud rate of the WSU is 1 Mbps. Refer to the
–
The WSU must receive charging commands regularly via message 0x19x otherwise, the CAN
bus watchdog will register Fault_WD_Comms as mentioned in 6.1.4. It is recommended that
these messages are sent to the WSU every 100 ms. Sending the message more frequently
runs the risk of overloading the bus, and sending less frequently could mean that one or two
dropped messages trigger a fault when there was no real danger.
–
If the voltage setpoint sent to the WSU is lower than the battery voltage then no current will
be delivered.

Useful debug information is sent on the following messages:
–
Comprehensive status and fault information are displayed in the Delta GUI, as shown in area
[3] of the Monitor tab as shown section 7.5.
–
Most faults can be cleared by sending a Demand_ClearFaults message 0x19x. However
