Swap mech between stations to identify a faulty
mech
Coin comparators come standard on a Trolls game that is not specifically ordered for use with a card
swipe system. These mechs are specifically designed to work with any size coin or token.
Coin mechs can be swapped between stations to identify a faulty mech.
3 items to check on the coin mech:
1.) Slide back the
housing and replace
the yellow plastic
chip with the coin or
token you are using.
The mech will com-
pare the coin insert-
ed to this coin.
2.) Ensure this switch is
up - to the N.C. position.
(For normally closed
operation)
3.) This is the pulse
speed position. Set to the
middle position for 50 ms
