Incorrect operation of machine. Otherwise check the mechanical condition of the throttle mechanism. Otherwise
check for wiring short circuits on the 20 way connector on the Trio, the 16 way connector on the LCD (if used)
and the wiring to the front panel switches & controls and those switches & controls themselves.

Check for wiring short circuits on the 20 way connector on the Trio, the 16 way connector on the LCD (if used)
and the wiring to the front panel switches & controls and those switches & controls themselves.
Check for wiring short circuits or broken wires on the 20 way connector on the Trio, the 5 way connector on the
LCD (if used) and the wiring to the front panel speed / throttle control and the speed / throttle control itself.
Central Command II V. 2 Fault Codes
All 150x codes - Check brake & wiring for open
or short circuit
Check the Traction motor connection on the Trio and check the wiring from this connector down to the Traction
motor and checking connections all the way. Otherwise possible fault in electro brake on traction motor or
possible Controller fault.
All 310x codes - Probable short circuit of output
device or wiring - can sometimes cause
permanent Controller fault.
Check the Traction, Brush and Vac motor connections on the Trio and check the wiring from these connectors
down to the Traction, Brush and Vac motors checking connections all the way and also checking for short
circuits. Check for wiring short circuits or broken wires on the 14 way connector on the Trio and the wiring
elsewhere on the machine. Otherwise replace Controller.
Inhibit inputs - Exact usage dependent on
programming
Remove or correct what is causing the inhibit. Otherwise check for wiring short circuits or broken wires on the
20 way connector on the Trio and the wiring elsewhere on the machine. Otherwise incorrect programming or
operation of machine.
