Circuit Breaker/Fuse
The fuse (optional circuit breaker) mounts to the rear channel. It carries all of the controls in the machine but
does not include the motor. To reset the circuit breaker just push in the button.If you have a fuse then remove
fuse holder and fuse and replace with a 11/2 amp fast blow type fuse on most models and 2.5 amp used for
75 lb model.
Control Mounting Trough
Remove top panel to access control trough. (see Removing Top Panel) It sets on the right side of the machine
and holds the control PCB’s ,transformers,and pressure switch
Micro-controlled Printed Circuit Board
Please be sure to be grounded to machine before removal of this board from machine.PC board
mounted vertically behind front control panel. Remove hold down nuts in 4 corners and 1 at bottom
center.
Main Relay Printed Circuit Board
Please be sure to be grounded to machine before removal of this board from machine. PCB mounted
in control trough towards front of machine. Remove 4 mounting nuts
.
PCB Transformer Step-down
Small transformer mounted at front of control trough that is powered with 120 VAC primary and two second-
ary outputs of 2.3 VAC and 24-27VAC.
Main Data Communication Cable
Goes between front PCB board and Variable Frequency Drive unit mounted center rear of machine.It
has telephone type connectors at each end and is inserted at Controller PCB and the Variable Fre-
quency Drive
.
Drop Coin Acceptor
The drop style coin acceptor contains a coin switch that is actuated by each good coin that is accepted.
Removal
The coin acceptor is removed by loosening the two Torx T-10 machine screws on the right side and by
removing completely the two Torx T-10 machine screws on the left side (#T-10 Torx driver, Dexter Pt. No.
8545-051-003). There are locking nuts on the back side that will have to be held. Needle-nose pliers work
well for this. Sliding the acceptor to the left will remove it from the slots in the front panel. This gives access
to the coin switch and acceptor for adjustments.
Coin Thickness Adjustment (see diagram)
On the right side of the acceptor there is a coin thickness adjusting screw "A" with a locking nut. To allow for
different thickness coins the screw can be turned in to accept thicker coins and turned out to reject thicker
coins. Start with a quarter of a turn on this screw and be sure to retighten the lock nut after adjustment.
Coin Height Adjustment (see diagram)
On the left side of the acceptor is a coin height adjusting bar "B". This bar is adjusted by loosening the two
mounting screws and moving both ends of the bar up or down equal amounts. The bar should be raised as
high as possible while still accepting the correct coins. If it is raised up too high, the good coins will be
rejected.
Coin Switch Adjustment (see diagram)
The normally open coin switch "C" should click (close) soon after the coin hits the operator wire. However,
there must be enough travel to allow the switch to reset (open) once the coin has passed. Adjustment should be
made by bending the wire very close to its attachment point.
