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.
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
Lamp On - Circuit is active
Lamp Off - Circuit is inactive
