Changer Operation / Maintenance
Tuning
TRC coin changers are factory preset to maximize valid
coin acceptance. However, periodic adjustments may be
required to correct differences that can occur when the
Acceptor/Gate Assembly and/or the Control
Board/Backplate Assembly are replaced. (
No special
test equipment is required for tuning adjustments.
)
In the Tuning Mode:
The coin changer is taught to recognize a set of coins.
As the coins are inserted through the Coin Cup, they are
placed into eight different tuning locations - two
locations per denomination [(nickel, dime, quarter, dollar,
Canadian and U.S.) Tokens on TRC-651x].
Two coins of
the same coinage may be used for acceptance.
The TRC-60x0 or TRC-6800 may also be taught to accept
a token in lieu of a coin.
Note: Dimensions and metal content will affect the
degree of success in using a token.
Depressing the Coin Return Lever during the tuning
procedure clears that tuning location.
After tuning, the changer switches to a calibration mode.
This mode serves as a fine-tuning function. Acceptance
will improve with the number of coins inserted.
Preparation - (In Vending Machine or Tester)
If tuning is required, perform these steps first:
1) Set one vend price to the highest programmable
price and activate the door switch for machine.
2) Turn the machine OFF.
3) Lower the Acceptor/Gate Assembly.
Manual Dispensing
of Coins
Operating the manual dispense switches /
buttons reduces the level of coins in the
coin tubes by operating the proper
dispenser solenoid. Coins are dispensed
at a rate of two per second. The VMC of
the vending machine is responsible for
sending the dispense signal to the
TRC60X0 or TRC-651X coin changers.
Refer to the vending machine manual for
operation procedure for dispensing of
coins from changer.
Solenoid Operation
When a solenoid energizes, the upward
motion of its plunger compresses a spring
and draws the solenoid lever, which in turn
pushes a payout slide forward (Figure 11).
This loads a coin for payout. When the
solenoid de-energizes, the spring force
returns the plunger to its de-energized
state, which returns the solenoid lever,
returning the payout slide, paying out a
coin.
