Hoppers (cont.)
Hopper Adjustments
Adjust Hopper Wiper: The wiper knocks off coins stuck
together, which allows only one coin to pass. To adjust
the wiper, follow these steps:
1. Turn the pin wheel to position a coin under the wiper.
2. Loosen both mounting screws and move the wiper
edge up to the coin.
3. Tighten both screws just enough to allow the wiper to
be moved in and out.
4. Slide a coin under the wiper edge and release it. The
coin should fall down onto the shelf wheel. The wiper
edge should be close to the coin, but not holding it.
5. Tighten the back screw, then the front screw, con-
stantly checking the wiper position to the coin. Con-
tinue to tighten the back screw then the front until the
wiper cannot be moved in or out. Do not overtighten
the screws as the head of the screw will break off.
Adjust Hopper Knife Position: The forward edge of the
hopper knife presses against the pin wheel and touches
the edge of the shelf wheel. This allows no coin to wedge
itself between the blade and the pin.
Removing the Mix Cylinder: The mix cylinder is used to
agitate coins in the hopper to prevent coin jams. It can
be removed for hopper maintenance or replacement if
necessary.
1. Remove the gear cover.
2. There are three bolts used to secure the drive motor
to the adaptor hopper. Remove the two bolts that are
in the recessed openings, and pull the motor up and
to the side.
3. Unscrew and remove the baffle.
4. Lift out the mix cylinder.
Hopper Probe Circuit: The hopper probe circuit consists
of two hopper probes. The first probe is a stationary pin
located at the bottom of the bowl. The stationary probe
and the moveable probe are electrically connected when
the coins in the bowl are touching both probes. When
the coins in the hopper are grounding to the stationary
probe, and are also touching the moveable probe, a sig-
nal is sent to the MPU board indicating the hopper is full.
The signal triggers the diverter coil on the door so that
coins will be diverted to the drop.
Setting the hopper probe circuit coin level
1. Fill the hopper with the desired number of coins. The
coins should be either level with, or slightly above,
one of the holes drilled into the side of the hopper
coin bowl.
2. Activate the forward switch for approximately five
seconds. This will agitate, and then settle, the coins
in the bowl.
3. Insert the top probe into the hole that is level with (or
just above) the amount of the coins in the bowl. This
sets the coin level for the chosen probe location.
