CONTROL PANEL OVERVIEW
5.1 Power Switch: The main power switch on the control panel (green lighted
I/O) controls all power to the oven. It must be in the I/On position before
any systems are operational. The green pilot light in the switch will be
lighted when the switch is in the ON position.
5.2 Timer Switch: The black I/O power switch marked TIMER is located to the
right of the main power switch. It controls the power to the time circuit. In
the O/Off position the oven heat is controlled with no timed duration. In the
I/On position heat is controlled for a timed interval and then the heat shuts
off.
5.3 Overtemperature Safety Thermostat: This control is marked HIGH LIMIT
and is equipped with an adjustment knob and a graduated dial from 0 - 10.
It is independent of the Main Controller and guards against any failure
which would allow temperature to rise past the Main Controllers set point.
This allows continued operation of the oven until the problem can be
corrected or service can be arranged. It is not recommended that the unit
be operated for extended periods of time using only the Overtemperature
Safety as the temperature controller as temperature uniformity will suffer.
5.4 OTP Light: This pilot lamp is directly above the Overtemperature Safety
Thermostat. The light will come on when the Safety Thermostat has been
activated and taken control of the oven. Under normal operating conditions
the pilot lamp should never be on.
5.5 Timer Control: This control is marked SET/TIMER and consists of a digital
display, UP/DOWN arrow pads, a RESET "PUSH" pad, a START/STOP
"PUSH" pad and a TIMER ACTIVATED light. This control provides the
ability to set a timed heat interval, activate the start-up of the timed heat
cycle and shut down the timed heat cycle automatically.
5.6 Main Temperature Controller: This control is marked
SET/TEMPERATURE and consists of the digital display and UP/DOWN
arrow pads for inputting set point temperatures and calibration.
5.7 Temperature Activated Light: This pilot lamp will be lit whenever the
elements are receiving power.
