Apply signal to activate the Start, Stop, and E-power functions as dened in the
programming settings. Verify that the 4-character display shows “St”, “SP”, and “EP” as
expected. If not, check programming settings (see Programming section). Set parameter
“L” to 1 and if the display is ashing “St”, “SP”, or “EP”, then there has been a fault in that
circuit. Check the manual circuit breakers and reset if necessary by pressing the yellow tab
on the circuit breaker.
Apply signal to activate the Throttle functions as dened in the programming settings.
Verify that the Throttle Relay Indicators D3 and D4 are activated. If not, check
programming settings (see Programming section).

Table 6. Fault Display
Problem Possible solution
Nothing is displayed on 4-character display. Check board power available at TB1 pin 3. If power is applied
and board is unresponsive, try resetting processor by removing
system power for at least three seconds. Then reapply power.
Relay Indicators D5, D6, D7 off with Ignition on. Check Ignition Splice. Check manual circuit breakers. Check
position of Aux Relay circuit breaker. With separate E-power
battery, circuit breaker should be between J5 and J6. Otherwise
it should be between J6 and J7.
No HOUR METER is displayed on 4-character display. Check board power and SST-4 Master input at J1 Pin 3.
HOUR METER is not counting (decimal not ashing) Check SST-4 Master input at J1 Pin 3. Check Programming
Parameter “o” for Hour Meter Input mode (Master or Spare).
Start/Stop or Throttle inputs do not activate D2 indicator. Check signal path for trigger signals Start/Stop (J1 Pin 5) and
Throttle (J1 Pin 4).
Displayed state of “St”, “SP” or “EP” are not as expected Check Programming Parameters C and D and timer durations.
Throttle Relay not triggering and Relay Indicators D3
and D4 are not illuminated.
Check signal path for Throttle signals into T1 and T2. Check
Programming Parameters A, B, and E.
