FILLING THE HOPPER
When the hopper has less than 40 - 50 coins left in it the red
“Empty” LED will light on the front of the changer. If you
have disconnected your LED, make sure the orange wire is
going to the terminal on the LED that has the red positive
mark next to it. Whenever the “Empty” LED is “ON” the
validator is disabled and it will no longer accept bills.
1. Turn OFF the power on the main logic board.
2. Slide the hopper out from the cabinet and insert the coins
through the opening on the top. There must be at least
enough coins to cover the two copper plates at the
bottom of the hopper. (Somewhere between 40 and
1000 coins minimum to maximum.)
3. Slide the hopper back into the hopper plate. Do not use
excessive force!
4. Turn “ON” the power switch. The “Empty” LED is now
off and the bill validator is ready to accept bills.
USING THE DUMP MODE TO EMPTY THE HOPPER
1. Open the cabinet door.
2. Turn OFF the POWER switch.
3. Place a suitable container in front of the hopper to catch
the coins.
4. Press and hold the “DUMP” button on the upper left
corner of the Main Logic Board. Turn ON the Power
switch. The red LED on the main logic board will come
on then go off. Once the red LED goes off, release the
“DUMP” button. If it is not released within two seconds,
the “DUMP” mode is canceled as a security feature. The
hopper will dispense coins until the POWER switch is
turned OFF. If the Red LED on the Main Logic Board is
not flashing 3-5 times per second the dump mode was not
accessed. Please try again.
FUSES
High voltage fuse:
This is the primary transformer AC fuse
for the main logic board and the validator. Any direct short of
the Transformer or validator will cause this fuse to blow.
Replace this fuse with a 2-½ amp AS fuse only.
REPLACING THIS FUSE WITH ANYTHING OTHER
THAN A 2 ½ AMP “AS” MAY RESULT IN A FIRE
OR AN
UNSAFE WORKING CONDITION
!! (See fig. 1 for
location of this fuse.)
Low voltage fuse:
This is the secondary transformer fuse for
the 5 - 28 vdc sections of the main logic board and hopper. It
is located to the left of the transformer. (See fig. 1) Replace
this fuse with a 2-½ amp AS fuse only. REPLACING THIS
FUSE WITH ANYTHING OTHER THAN A 2 ½ AMP
“AS” MAY RESULT IN A FIRE
OR AN UNSAFE
WORKING CONDITION
!!
Functional Description of the Series AC400/500 Changer
To follow along with this walk-through of your changer, fill
the hopper with coins and turn the changer on.
1. When power is applied the validator will cycle twice.
The out-of-service LED flashes then goes out. The green
LED on the main logic board comes on steady, and the
red LED on the main logic board will light then go off
then flicker on once per second in the standby mode.
2. During the power-up mode the main logic board relay
clicks twice enabling power (120vac) to the validator.
When this relay is not enabled it routes 12vdc ground to
the out-of-service LED. Without power to the validator
the changer cannot accept bills. Since we are not in the
error mode, the red LED on the validator logic board is
on steady.
