The following guidelines are intended to ease the
solution of potential problems that may be encountered
during the everyday operations of the machine.
OPERATING ISSUE
Conveyor does not power
on.
Conveyor powers on but
conveyor does not run.
Conveyor powers on but
belt does not heat up.
Tunnel powers on but does
not heat.
Tunnel conveyor not
tracking.

TROUBLESHOOTING
Check incoming power. Confirm ON/OFF switch is flipped to the "on" position.
Check power supply line.
Check the position of the conveyor speed control knob.
Check the voltage to the DC drive board. The incoming voltage should be equal to
the line voltage.
Check the voltage from DC drive board. The voltage is DC and will vary with the
speed setting. If there is no output voltage, replace the board, 203-62.
Check the wiring to the motor. Replace the gear motor.
Check the position of the conveyor temperature control knob.
Check the voltage to the voltage controller. The incoming voltage will vary with
the speed setting.
Check heat element for continuity. The 120V element has a resistance of 97 ohms.
NOTE: The resistance given is a nominal value.
Check incoming power. 20-amp service is required.
With power removed check if the thermostat is turning on by checking continuity
across wires #1 and #3.
Check the resistance of the heating element. The 120V element has a resistance of
23 ohms.
NOTE: The resistance given is a nominal value.
Ensure the voltage matches the element voltage.
Check the operation of the blower motor.
Check for air leaks around the blower housing and manifolds.
Check tension roller on assembly (belt will track to tighter side). Be careful not to
overtighten.
Check for worn belt.
Check the condition of the belt guides. The belt guides should just touch both sides
of the belt.

The cause/solution statements are generally arranged
in order of most probable, easiest solution first on up to
more involved, difficult solutions. If all possible solutions
have been tried, the distributor or factory should be
consulted.
