ADDITIONAL FUNCTIONS
The conveyor belt direction and the temperature display can
be changed on the conveyor oven by a qualified 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 flashing 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 flash the error message.
