Fault Finding
The MillipaK controller includes a number of features designed to help the user track down
operational faults, wiring faults or internal controller faults.
The Diagnostic LED mounted next to the calibrator connectors on the front of the controller
serves as a simple diagnostic tool as explained below:
ON No fault, normal condition
OFF Internal controller fault
1 flash Personality out of range
2 flashes Illegal start condition (Traction)
3 flashes MOSFET Short Circuit
4 flashes Contactor fault or Motor Open Circuit
5 flashes Not used
6 flashes Accelerator wire off fault
7 flashes Low or High battery voltage or BDI cutout operating
8 flashes Over temperature or timed cutback
10 flashes Power Up Autozero has not yet been completed
Table 10: Flash Fault Descriptions
In addition to the LED indication a more detailed description of any faults detected may be found
by using the calibrator. Menu item number 13.01 gives a code which corresponds to the following
detected faults:
