Programmable Logic Controller (PLC)
LED Indications
The PLC operating system is designed to enhance the functionality of the unit and the safety of the cooking
environment.
The system relies on input from a set of thermostats to control the fan and shuto power to the stove when the
temperature reaches preset points.
As the temperature rises, the PLC monitors the environment with the 3 thermostats. The board is programmed
to respond to 2 temperature thresholds: the rst at 150 deg F and the second at 190 deg F.
At the rst temperature threshold the ventilation fan will turn on, REGARDLESS OF THE FRONT PANEL SWITCH
SETTING.
At the second temperature threshold, several events happen:
1) The power disconnect to the stove (valve or contactor) is de-energized, shutting o power to the stove;
2) The “local” alarm output is tripped, indicating a trouble condition with the unit. This output is from
contacts C0 and Y0 on the PLC.
3) The on-board audible alarm sounds (high pitched tone).
