36Service Manual – SC6000 04 - Control System
System Menu
The system menu displays the rmware revision number and
the serial number of the control board. It also provides access for
updating the rmware, and checking the impact log.
Impact Log
If an impact event occurs and the machine has been set up for the
“lock out” option, a pad lock symbol is shown to the operator and
scrubbing functions are inhibited. The machine can still be driven., but the machine must be powered on
using a supervisor key to “reset” the lock out and restore scrubbing functions.
The impact log will display a list of impact events with an impact value of acceleration in 1/1000 G’s
(Gravity). If an individual impact event is viewed, all three axis of acceleration are displayed.
Troubleshooting Guide
Any error codes initiated by any module will be sent to the main controller via the CAN Bus, and shown
on the display and recorded to the log. Each of these codes for the main controller and power module are
listed in the tables below, along with some basic troubleshooting steps to help isolate the cause. The Drive
Controller (E4) Error Codes are listed in the Wheel System, Traction chapter on page 50.
Main Controller (E2) Error Codes
Code Description Comments
1-001 K1 Coil Open The controller has detected an open circuit to the KSI relay coil. The most
likely cause is a loose wire.
1-002 K1 Coil Short The controller has detected a short circuit to the KSI relay coil. Inspect the
wires between the controller and the relay (also located in the steering
column) for shorts. Otherwise, replace the relay.
1-003 K1 Contact Weld The controller has detected that the KSI relay output power is active after
the controller has de-energized the relay coil.
• Disconnect the relay output wires. If the condition persists, then it is
known to be a short in the wires.
• If the condition clears after disconnecting the output wires, then it is
known that the contacts have fused and the relay must be replaced.
1-010 CAN Bus 0 Fault with the main controller’s CAN-0 bus (TrackClean)
1-011 CAN Bus 1 Fault with the main controller’s CAN-1 bus (power module and drive
controller)
1-101 L1 Short The controller has detected a short at the Solution Solenoid.
• The most likely cause is a damaged solenoid with an internal short.
• Check the coil resistance of the solenoid. If it is signicantly below the
normal coil resistance of 108 Ω, then replace the solenoid.
1-102 L2 Short The controller has detected a short at the optional Dust Guard Solenoid.
• The most likely cause is a damaged solenoid with an internal short.
• Check the coil resistance of the solenoid. If it is signicantly below the
normal coil resistance of 126 Ω, then replace the solenoid.
