CONTROLLER LAMPS _____________________________________________________

The controller is a solid state device that monitors and
controls electrical functions. The controller receives input
signals from various switches and sensors throughout the
machine and transmits output signals to operate relays,
solenoids and warning lights. It controls and resets timers
and contains built in logic to control certain machine
functions.
Each input and output signal is displayed through lamps
located on top of the controller. A closed input switch
indicates an active circuit and will turn an input lamp on. An
open switch an inactive circuit and will turn a lamp off.
Outputs are active when their lights are on.
Lamp On - Circuit is active
Lamp Off - Circuit is inactive

It is important to note that in some cases a lamp or group of
lamps must be on or off for a condition to be true. For
example, to start the mower the Mow Switch must be OFF
(lamp 8 off) while the Neutral Start Switch (lamp 12), Brake
Switch (lamp 6) and Fuel Valve Hold Coil (lamp 27) must be
on.
NOTICE
For factory assistance with troubleshooting controller
problems, please note the controller hardware revision
and software version located on the lower right corner of

greater revision levels will be backward compatible.
