LED
A Status LED located on top of the controller flashes a fault identification code
if a fault is detected by the controller. The fault codes are listed in Table 1. The
code will continue to flash until the fault condition has been cleared during
active fault detection. This will typically happen after cycling KSI for power-up
fault conditions, and cycling the brake for faults detected during operation.
MOSFET
A MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a type of
transistor characterized by its fast switching speeds and very low losses.
MultiMode™
The MultiMode™ feature of these controllers allows the vehicle to be operated
with two distinct sets of characteristics. The two modes can be programmed
to be suitable for operation under different conditions, such as slow precise
maneuvering in Mode 2 and faster, long distance travel in Mode 1. The fol-
lowing parameters can be set independently in the two modes:
— main current limit
— plug current limit
— ramp start current limit
— acceleration rate
— maximum speed
The operating mode is selected by means of the mode selection switch. If
Mode 1 is not selected, the controller operates by default in Mode 2. When
the controller returns to Mode 2 from Mode 1, it automatically changes the
main current limit, the plug current limit, the ramp start current limit, the
acceleration rate, and the maximum speed to their Mode 2 values.
If the anti-tiedown feature is active, Mode 1 must be re-selected each time
the brake is released.
Neutral brake
The optional neutral brake feature provides automatic plug braking in neutral.
If this option is not selected, the vehicle is free to coast in neutral. The neutral
brake plug current limit is programmable.
Overtemperature
At overtemperature (from 85°C to 95°C), the drive current limit is linearly
decreased from full set current down to zero. (Plug current, however, is not
reduced—in order to provide full vehicle braking under all thermal conditions.)
