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 Seat Fault
3 flashes MOSFET Short Circuit
4 flashes Not used
5 flashes Not used
6 flashes Not used
7 flashes Low battery voltage
8 flashes Over temperature or timed cutback
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:
ID Fault Description Flash Fault
0 System OK On
1 Thermal Cutback Maximum power available to the motor has
been reduced due to excessive Heatsink
temperature.
8
2 Timed Current Limit Cutback Maximum power available to the motor has
been reduced by the Timed Current Limit
Cutback function.
8
3 Low Battery Fault Battery voltage is too low. 7
9 Seat Fault Seat Switch Fault has occurred 2
4 Configuration Range Fault A personality is out of range. 1
5 Configuration CRC Fault The personality CRC is incorrect 1
6 MOSFET On MOSFETs pulsed during power on failsafe
checks (failsafe circuit disabled).
0
7 MOSFET Short Circuit Short circuit MOSFETs detected. 3
8 MOSFET Short Circuit during
Power Up
Short circuit MOSFETs detected during
power on failsafe checks.
3
10 Drive 1 On Contactor 1 pulsed during power on failsafe
checks (failsafe circuit disabled).
0
11 Drive 1 Off Contactor 1 did not pulse during power on
failsafe checks (failsafe circuit enabled).
0
12 Drive 2 On Contactor 2 pulsed during power on failsafe
checks (failsafe circuit disabled)
0
13 Drive 2 Off Contactor 2 did not pulse during power on
failsafe checks (failsafe circuit enabled).
