TROUBLESHOOTING
The following guidelines are intended to ease the solu-
tion of potential problems that may be encountered
during the everyday operations of the machine.
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.
OPERATING ISSUE
RECOMMENDATIONS
Conveyor does not power on.
Check incoming power. The ON/OFF switch should be lit.
Check power supply line.
Check On/Off switch on the operator panel.
Conveyor powers on but
conveyor does not run.
Check the position of the Conveyor Speed Pot.
Check the fuse(s) to the DC Drive board.
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 pot setting. If
there isn’t output voltage, replace the board, 203-62.
Check the wiring to the motor. Replace the gear motor.
Conveyor powers on
belt does not heat up.
Check the position of the Conveyor Temp Pot.
Check the voltage to the Voltage Controller. The incoming voltage will vary with the speed pot
setting.
Check heat element for continuity. The 220V element has a resistance of 97 ohms. (Note that the
resistance given is a nominal value.)
Tunnel powers on but does not
heat
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 220V element has a resistance of 23 ohms. (Note that
the resistance value 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.
Tunnel conveyor not tracking
Check tension roller on assembly (belt will track to tighter side). Be careful not to over tighten.
Check for worn belt.
Check the condition of the belt guides. The belt guides should just touch both sides of the belt.
