DISPLAY INFORMATION
When operating the oven, there are three levels of access:
1. Store Level - General employees would know these functions and how to change them.
While the oven is running, enter this mode by holding the DOWN and UP arrows (
)
simultaneously for four seconds. The TIME display goes blank and the TEMP setpoint is
displayed. Adjust with the DOWN or UP arrows. The ENTER button (
) toggles between
TIME and TEMP. The parameter that can be adjusted is displayed, the other is blank.
When TIME and TEMP are adjusted as needed, wait
fi
ve seconds and SAVE is displayed.
The values are accepted and the controller begins controlling to these new values. The
conveyor continues to operate at the same speed until a new value is accepted. The
temperature control output should be OFF during changes.
2. Manager Level - This is a lock so that TIME and TEMP cannot be changed even at the Store
Level. While the oven is running, enter this mode by holding the DOWN and UP arrows
simultaneously for 4 seconds. The TIME display goes blank and the TEMP setpoint is
displayed. Release the UP arrow and continue to hold the DOWN arrow for an additional
4 seconds. The TEMP display shows LOC as the TIME display shows nO, which indicates
that the TIME/TEMP parameters can be changed after reaching the STORE level. yES
indicates that the parameters cannot be changed even after entering the STORE level.
The LOC setting can be toggled using the ENTER button (
).
ADDITIONAL FUNCTIONS
The conveyor belt direction and the temperature display can be changed on the conveyor
oven by a quali
fi
ed technician. To change the belt direction, the technician must reverse the
motor direction and rotate the conveyor belt for proper oven function. A technician can also
change the temperature display from Fahrenheit to Celsius. These changes can be made by
the technician during the start-up/check-out or at a later date.
ERROR CODES
Error codes will display as
fl
ashing text messages for diagnostic purposes. Any temperature
or thermocouple error should turn the temperature output OFF and leave the conveyor running
at the same speed. The belt error should turn the temperature output OFF. The speed error
should display when the motor is unable to settle at the chosen speed. This might occur if a
fast speed is chosen that the motor is unable to spin fast enough to achieve. The speed signal
output will remain the same but the display will
fl
ash the error message.
