LOW COIN SENSOR ELECTRICAL CHECK
Perform the following procedure to ensure that the Low Coin Sensor is functioning properly.
1. Turn the Bill Changer power to OFF.
2. Remove the hopper and empty it of all coins.
WARNING:
Make sure that the power is OFF before performing the following step.
3. Locate connector P3 on the Changer Control Computer (CCC). Connect a DC
voltmeter to P3-5 (GND) and P3-4 (+).
4. Replace the empty hopper and turn Bill Changer power to ON. The voltmeter
should read less than +.5 volts DC.
5. Tape 2 x 2 inch piece of aluminum foil around the end of a non-metallic object
such as a long plastic ruler or wood stick. Figure 6-3, the Hopper Cleaning Brush
is good for this purpose.
6. Place the foil end of the test object
inside
the hopper as close as possible to the
location of the sensor
(Figure 6-2, Hopper Sensor Area)
. The voltmeter should
now have a reading of no less than 4.3 volts and a maximum of 5.5 volts.
