Single Coin Acceptor
The Wash Select II comes standard with the model PEM-35 single coin acceptor. In this
section, you will find instruction for proper maintenance of the PEM-35.
3.4.1
Replacing the Reference Coin
For proper operation of the coin acceptor, you must have a sample of the coin to be accepted
(U.S. quarter) in the sample holder. The Slug-Buster II (model PEM-35) comes from the
factory with a U.S quarter already in the sample holder.
You may use the following steps to assist you when replacing the reference coin.
Warning:
Never loosen a nut on the Slug-buster II that is covered with BLUE or RED paint.
1.
Loosen the retainer screw or nut just enough to allow the retainer slot to slide
freely.
2.
Remove the sample coin currently in the sample holder from the side of the
retainer slot.
3.
Slide the retainer toward the sensing coil until it is firmly seated. (The sample
must be centered in the sensing coil and seated in the “V” groove to function
properly.)
4.
Once the retainer is back in place, tighten the screw or nut.
3.4.2
Adjusting the Selectivity to the Coins
There should be no reason to change the selectivity of your new unit since it was shipped
from the factory with a tested, pre-set coin already installed. However, if you find it necessary
to replace the coin samples with a different type of coin, the selectivity of the unit must be
readjusted. Before this can be done, a standard acceptance test should be performed. The
test is performed by dropping several valid coins into the Slug-Buster II, including common
slugs, and verifying that the proper coins are credited and that the slugs are rejected. If the
acceptor does not recognize all of the coins, or does not reject the invalid coins, the following
procedure should be implemented.
Note:
The coin acceptor must be powered to make a valid adjustment to the sensitivity. You
must also avoid testing the Slug-buster II with the door open in direct sunlight. If the
Slug-Buster II main mechanism is exposed to direct sunlight, it may fail to credit the
coin.
