Section 3 – OPERATION
I. LOCATION AND DESCRIPTION OF CONTROLS:
a. Fan
Switch:
Located on the Global-Mod™ Control Panel, it is the topmost of three rotary switches.
This switch turns both the internal and cooling fan(s) on and off. When set to the “ON” position, it
also allows the heat and conveyor functions to activate. NOTE: Your oven has an automatic cool
down feature that will keep the fan(s) running for thirty (30) minutes after the Fan Switch has been
turned off. This is a timed feature that will activate every time the Fan Switch is turned to the “ON”
position regardless of the temperature in the oven cavity. NOTE: 3270 models will have one Fan
Switch in each of its two (2) Global-Mod™ Control Cabinets. Both switches must be switched to
the “ON” position.
b. Burner
Switch:
Located on the Global-Mod™ Control Panel, it is the middle of the three rotary
switches. When the Fan Switch has been set to the “ON” position and the fan(s) are running,
turning the Burner Switch to the “ON” position will activate the heating system in your oven. NOTE:
there is a built in safety feature in gas-fired ovens that provides a 30 second purge period to clear
any unburned gases from the oven prior to initiating the ignition sequence. Setting the Heat Switch
to the “ON” position will also activate the LED display on the Temperature Controller. NOTE: 3270
models have two burners and will have one Heat Switch in each of its two (2) Global-Mod™ Control
Cabinets. Both switches must be switched to the “ON” position to operate the two burners.
c. Conveyor
Switch:
Located on the Global-Mod™ Control Panel, it is the bottom of the three rotary
switches. When the Fan Switch has been set to the “ON” position, turning the Conveyor Switch to
the “ON” position will turn the Conveyor Drive Motor on and activate the LED display on the
Conveyor Speed Controller. NOTE: 3270 models will have one Conveyor Switch in each of its two
(2) Global-Mod™ Control Cabinets. Both switches must be switched to the “ON” position to
operate the conveyor.
d. Conveyor Speed Controller:
Located on the Global-Mod™ Control Panel, this control monitors,
displays and adjusts the belt speed. Measured in minutes and seconds, the time displayed
indicates bake time from “tip-in” to “tip-out”. NOTE: Belt speed should not be confused with “Time
of Delivery” which is the elapsed time from the product’s leading edge entering the bake chamber
(“tip-in”) until the product’s trailing edge completely clears the bake chamber (“tail-out”). Single-belt
models will have one controller. Split-belt models will have one controller for each conveyor belt,
labeled “FRONT” and “REAR”. NOTE: 3270 models will have this control in the right Global-Mod™
Control Cabinet (as viewed from the front of the oven). Both Conveyor Switches must be in the
“ON” position for the conveyor to run. Turning either Conveyor Switch off will stop the conveyor.
e. Digital Temperature Controller:
Located on the Global-Mod™ Control Panel, this control
monitors, displays, controls and adjusts oven temperature. LED displays indicate oven setpoint
and actual temperature. Keypad controls allow the operator to select the cooking temperature and
monitor oven operation.
NOTE: 3270 models will have one Temperature Control in each of its two
(2) Global-Mod™ Control Cabinets. N
OTE:
Temperature is monitored in the air plenum and
may not reflect actual temperature in the oven chamber.
