Safety
The MillipaK controller contains a triple fail-safe system to give a high level of safety. If the
diagnostic LED is not illuminated or flashes, the safety circuit may have tripped and the truck
may not drive.
The controller must be used with a line contactor as indicated in the wiring diagrams.
As blow-out magnets are fitted to contactors (except 24V) ensure that no magnetic particles can
accumulate in the contact gaps and cause malfunction. Ensure that contactors are wired with the
correct polarity to their power terminals as indicated by the + sign on the top molding.
The MillipaK controller may be used with suitable onboard chargers, as supplied by Sevcon.
There are several software features which are intended to prevent inadvertent or unexpected
vehicle movement – SRO, Accelerator power up fault and sequence checking. Some of these
features cannot be disabled and the appropriate signals must be supplied to the controller before
drive will be allowed.
