SECTION 3: GENERAL CHANGER OPERATION
Housing Module
The Housing Module consists of the changer
housing and MDB harness. The backside of the
housing has three mounting holes for attaching
the Guardian
GLX
changer to the vending ma-
chine. The
changer's
cashbox coin chute is
also part of the housing.
Coin Tube Cassette
The coin cassette contains the six coin tubes
that store coins for change payout. The
center
slot
of the cassette
is
the
changer's
coin return
chute. Rejecte
d coins from the acceptor pass
through the center of the cassette assembly
and fall out the bottom of the coin changer.
Accepted coins are guided into the coin tubes.
Payout Module
The bottom of the Guardian
GLX
changer is the
Payout Module. Coins stored in the coin tubes
of the cassette are dispensed by the payout
module’s motor driven belt. The belt has two
pins attached to it, which engage a sweeper at
the bottom of each coin tube. When the
sweeper is engaged, one coin is released from
the coin tube. The acceptor module sends
information to the payout module for dispensing
coins from the cassette.
Coin Level Sensing
The Pulse-Echo coin level sensing method emits
and detects sound waves. The number of coins
is calculated by the amount of time it takes the
emitted sound wave to reflect o
f
f the coin stack
and return to be detected. (See Figure 16)
How often does the changer scan the
tubes?
The Guardian GLX will automatically scan
after any coin deposit or payout. It will also
scan after any “change in state”, e.g. when
the payout cassette is reinstalled or when
the sorting door is opened then closed.
I added one coin to a tube and the coin
level sensing did not detect it. Why?
The
Pulse-Echo coin level sensing method is
accurate to within
±
2 coins. It may not
necessarily detect a difference when a
single coin is added. This is normal and is
within the technology’s margin of error.
Does the Guardian
GLX
require tube
sensing calibration as with some other
models?
No, it does not require any calibration to
attain its level of accuracy.
