5: Possible Cause: Defective wiring or wiring connections.
5: Possible Solution: Using the schematic on in the back of the manual test the electrical circuit from the control
board to the vend motor. This may be tested by using an ohmmeter with power removed or using a voltmeter
if power is left on.
B. SYMPTOM: A SELECTION MOTOR RUNS SLOWLY
1: Possible Cause: The selection helix assembly is dragging and will not run at a normal speed.
1 : Possible Solution: Check to see if the product that is loaded in the helix is free from obstructions on both
sides. Check to see if also the product is not too tight for the helix size being used. This may be done by lifting
the product up out of the helix by hand. If the helix is also lifted off the tray, then that product is too tight for
that helix size. Move the product to larger size helix so it may vend freely.
2: Possible Cause: The power from the transformer is low causing the power supplied to the motors from
the control board to be low.
Possible Solution: Using a voltmeter test the output from the transformer at the junction box the third plug
from the left. The output may be tested from the yellow to the red wires. With a voltmeter test to see what
the voltage is at the motor. It should be 24 VDC. CAUTION: WHEN TESTING ELECTRICAL VOLTAGES,
USE EXTREME CARE NOT TO GET ELECTRICALLY INJURED.
3: Possible Cause: Defective vend motor.
3: Possible Solution: To test to see if a vend motor is working, unplug the tray with the defective motor and
plug the tray into a known good location. Now service vend the tray assembly with the bad motor. If the motors
run in the new tray location, then we know that the motor is good. To service vend a single selection or a
complete tray assembly, see section on test vending. If the motor is defective, replace the defective motor
and service vend the new motor twice to insure proper operation
4: Possible Cause: Defective control board.
4: Possible Solution: Replace control board.
NOTE: When you replace the control board ALWAYS DISCONNECT POWER TO THE EQUIPMENT. After
the control board is installed, apply power, go into the service mode and press selection button then press
selection button You have now aligned the control board with the motors. It will also be necessary to set
your prices.
5: Possible Cause: Defective wiring or wiring connections,
5: Possible Solution: Using the schematic in the back of the manual test the electrical circuit from the control
board to the vend motor. This may be tested using an ohmmeter with power removed or using a voltmeter
if power is left on. See Note 3.
