Controller
DANGER
DANGER
The controller is located on the streetside right interior of
the enclosure, behind the vent and front covers. It
monitors and regulates motor and battery voltage,
temperature, current and charge level during operation to
maintain system performance. It produces the required 3
phase AC current that powers the motor and pump
assembly. Also communicates with the display module to
present this data to the operator. The controller has a
operating temperature range of -40°F to 104°F (-40°C to
40°C).
The controller has a red fault light located on the top left
of the front face. It will flash in a timed sequential pattern
to display Master and Supervisor Microcontroller single-
and double-digit fault codes.
Master Single-Digit Fault Code will blink 0-9 times, delay
for 2 seconds, then repeats code (5 blinks, 2 second
delay, 5 blinks = fault code #5).
Master Double-Digit Fault Code will blink the first digit 1-9
times, delay for 1 second, blink the second digit 1-9
times, delay for 2 seconds, then repeats code (5 blinks, 1
second delay, 2 blinks, 2 seconds delay, 5 blinks, 1 sec-
ond delay, 2 blinks = fault code #52).
Supervisor Fault Code is the same as a Master except,
starts with a 2 second steady on light,

1. SHOCK HAZARD - Batteries are in a parallel
circuit, this increases the system’s amps,
capacity and energy. Use proper insulated
tools and procedures when working with
batteries.
2. SHOCK HAZARD - DO NOT touch terminals,
Use proper insulated tools and procedures
when working with batteries.
