SPECIFICATION

Up to 8 coins may be validated in the physical
range 16 mm to 32 mm diameter and
thickness to 3.5 mm. Coins are validated
optically for a diameter measurement and
washer detection, plus the rate of travel.
Resistivity and permeability measurements
are also taken for metal type verification.

Two tables of acceptance / rejection criteria
are included in the design (wide and narrow).
Selection is by a dip switch on the side of the
validator (accessed without tools) and in
normal operation the wide setting is used for
best acceptance of worn or damaged coins,
but in case of potential fraudulent use, the
narrow setting is easily engaged.

Another switch engages the diagnostic
reporting function where any coin not
validated will momentarily show a code on the
display, indicating the reason for the failure to
validate, plus other codes for other fault
conditions.

There are a further 6 dip switches that can be
used to invalidate the acceptance of different
coin denominations. These refer to the first 6
coins in the set up table (which usually covers
all those normally required). Switched to the
Validate positions coins will be accepted as
normal, but if any switch is in the Invalidate
position that coin will be automatically
rejected. In this way the range of coins to be
accepted can be quickly set without needing
to reprogramme the validator. Note, after
changing a switch position turn the supply for
the system off and then on, to electronically
reset the old switch positions.

Operation by 12 Volts, A.C. or D.C.

Inclusion of an inbuilt transformer to allow a
primary supply voltage of the customer’s
choice (240V 50 cycles for Australia).

As an alternate to the isolation transformer a
solid state regulator can be fitted, allowing
operation of the validator on 24V A.C. or D.C.

4 relay output (with common line), contacts
rated at 10 Amps on 240 Volts. These are
derated to 5 Amps for safety. If the contacts
are to be isolated from each other the number
of relays reduces, due to limitations on input
terminations.

4 optocoupler inputs that operate on a
nominal voltage of between 5 and 24 Volts
A.C. or D.C. (limits in the order of 2 to 30
Volts). These same optocouplers have
separate pin strip connection for a D.C.
sourcing current of approximately 3 - 30
milliAmps (LED input). On this pin strip there
are an additional 4 opto isolated inputs.

On the main plug in / screw connect terminal
block are two connections for audit require-
ments. Bridging these (external key switch,
etc...) causes the display to show the total of
coins since the system was installed, followed
by the value of coins since the audit function
was last interrogated. (Refer to data retrieval
for full instructions).

It is possible to expand the validator /
controller to give up to four additional relay
outputs on two separate commons.

validator then scroll through the coins until C8
is on the screen.
11. Turn the power off. If recalibrating an existing
coin set (no new coins or tokens calibrated)
then set the dip switches to their normal
operating position (normally all down to accept
all calibrated coins) and return power to the
validator. Check the validator is crediting the
coins correctly by inserting several coins of
each type. Calibration is now complete.
12. If a new coin or token was calibrated then it
will need to have a value assigned to it. Put all
the dip switches in the up (ON) position and
re-apply power. The screen will settle on
"Par".
13. Put all dip switches down (OFF) except
number 3 which remains up.
14. Press the NEXT button once, the screen
should say "Val"(value).
15. Press the button marked SET and the screen
should say C1, this is coin 1 and should be
the lowest value coin being used.
16. If coin 1 is the coin which you wish to assign
a value then press the button marked SET,
the screen will show 00.00 (or the coin value
it had previously been assigned) the last digit
will be flashing.
17. If this isn't the coin you wish to set then press
the NEXT button until the desired coin is
reached and then press the SET button.
18. To change the flashing digit press the NEXT
button.
19. To progress to the next digit press the SET
button. Continue steps 18 and 19 until the
correct value has been set. Once the first digit
is flashing then pressing the SET button will
return the screen to C1-C8.
20. Once all the coin values have been set turn
the power off.
21. Set the dip switches to their normal operating
position (normally all down for the coin
validator to accept all calibrated coins) and
return power to the validator. Check the
validator is crediting the coins correctly by
inserting several coins of each type.
Assigning value is now complete.
NOTE: calibration has occurred with the three parts
of the validator as a set. Mixing the parts between
different validators may put the calibration slightly
out.

Using the SET and NEXT push buttons, plus the 8
way dip switch, located on the side of the coin
validator, in conjunction with the display, it is
possible to calibrate for any coin set. This is
normally a factory operation, but it can be done
by a skilled technician.
Coins must be in the physical range 16 mm
minimum to 32 mm maximum and thickness up to
3.5 mm. Calibration can be implemented for any
number of coins from 1 to 8.
When calibrating the validator a minimum of two
coins of each type should be used. One in near
new condition with no wear on the knurling around
the coin and the second should be with the
knurling worn. These then present the extremes of
coins which will be used in the validator. NOTE:
There is a time out on later versions of nine sec-
onds where if one of the tables haven't been
accessed the validator will revert to normal mode
and accept C7 and C8 only. Therefore you have
nine seconds to get from step 3 to step 6.
1. To calibrate a C22P coin validator first
remove power from the unit.
2. Put all 8 dip switches in the up (ON) position.
3. Re-apply power, the screen will settle on
"par" (parameters).
4. Put all dip switched down (OFF) except
number 3 which remains up.
5. Press the button marked NEXT twice and the
screen should then say "cal"(calibrate).
6. Press the button marked SET the screen
should say C1, this is coin 1 and should be
the lowest value coin being used.
7. If this is not the coin you wish to recalibrate
then press the NEXT button until the desired
coin number appears on the screen. Normal
coin assignments for Australian coins is
C1=5¢, C2=10¢, C3=20¢, C4=50¢,C5=$1,
C6=$2, C7=Token 1, C8=Token 2.
8. Make sure the coin validator is held firmly and
vertically on a flat surface, or its normal
mounting position, when inserting 100
samples for the coin being calibrated; thrown
in as well as rolled in. The display will count
the samples inserted, with the coins returned
via the reject slot.
9. Once 100 samples have been inserted, press
the NEXT button to progress to the next coin;
C2 should be on the screen. Insert 100
samples of coin 2. Continue the above
procedure for each coin that requires
calibration.
10. Once you have finished calibrating the

The normal calibration procedure is all that is
ever needed and the following information is
for special circumstances only.
Sometimes there is a desire to vary the standard
calibration criteria, to invalidate a closely matched
fraudulent coin or increase the certainty of correct
validation of closely matched coins. Understanding
the calibration criteria and recording set values in
a table will allow evaluation of the equipment's
operation and from this it can be seen where
adjustments to the calibration criteria will help in
achieving a particular result. First understand that
there are three measurements being taken for
each coin, (optical detection of diameter and
"induced" electronic readings referred to as
amplitude and period. For each of these parameters
there is a reference number that is set into the coin
validator calibration tables. It is possible to write up
a table indicating these readings.
1. Follow steps 1. to 7. from the calibration
procedure and bring the desired coin on to
the screen.
2. Press the SET button this will show the first
entry of the coin table, it should be between
3000 and 7500.
3. Enter the displayed values for all coins in the
table provided, this will then help to show how
far each parameter can be adjusted before
overlapping another coin and possibly
causing miscredits. Also if any adjustments
made to parameters cause problems then
you have a record of the original values that
you can enter back into the validator.
4. To move to the next coin parameter press the
NEXT button.
5. After all parameters for that coin have been
displayed the screen will return to C1-C8.
6. To advance to the next coin press the NEXT
button.
7. To display parameters for the coin press the
SET button.
8. Repeat steps 3 to 7 until all coins have been
recorded.
9. An overlap in all 3 parameters (diameter,
period and amplitude) between 2 or more
coins will cause miscredits of coins which
fall into these parameters, but ONLY if they
occur simultaneously.
10. To change parameter press the SET button
while that parameter is on the screen. The
last digit (right side) will flash, this is the digit
that can be adjusted.
11. To advance the value of the flashing digit
press the NEXT button. The digit can then be
scrolled from 0 to 9 and back to 0.
12. To move to the next digit press the SET
button.
13. Repeat for all digits and once the first digit
(left side) is flashing then pressing the SET
button. The display will return to the coin
number, C1-C8.
14. Press the NEXT button to advance to the next
coin and repeat steps 10 - 13 to change other
coin parameters.
15. After adjusting the desired parameters make
sure the screen is showing a coin number C1-
C8. Remove power to the validator.
16. Set the dip switches to their normal operating
positions and re-apply power.
17. Test the validator to see if the adjustments
made do not cause problems with any of the
coins normally used.
NOTE: Some time a difficult fraudulent coin can be
"calibrated" so as to record its reference numbers
(Diameter Period and Amplitude). Then the
validator is recalibrated to remove the fraudulent
coin details, but the numbers taken can be used to
determine how best to adjust the Diameter Period
and Amplitude readings for the valid coin set.

TO PROGRAM COPY PRICES
1. Remove supply power to the validator.
2. Locate Dip Switches and Push Buttons and
set all Dip Switches to UP (or ELIMINATE)
3. Turn supply power back on.
4. While Display is scrolling though
“ABBERFIELD” etc. Set all Dip Switches to
DOWN (or VALIDATE) position.
5. When Display shows “PAR” press SET
button once so that display now shws “P0”.
6. P 0 is price #1.
7. To change this price push the 'SET' push
button again.
8. The display will then show the current price
for this price with the last digit flashing 00. 0
9. To change this digit push the 'SET' push
button until the desired figure is shown, 0 to 9.
10. To change another digit push the 'SET' push
button until the desired digit is flashing.
11. Then push the 'NEXT' push button to change
its value.
12. Once you have stepped through all 4 digits
then the display will read 'PO'
13. Again, to advance to the next price push the
'NEXT' push button until the desired price
position is reached.
14. PO to P5 are the price positions for prices 1
to 6.
15. To change all the prices repeat above
procedure.
16. Do not change P6 to P9 unless instructed
by the manufacturer.
17. Once all the prices you desire the validator to
work on have been set, turn the validator off
and then return the dip switches to their
normal position, (usually all down). Then turn
the power back on.
A data retrieval mode allows the unit to display the
number of operations at each price since the last
resetting of the log data.

When the display shows 'End' if the Audit log input
is shorted again more than 2 seconds then the
total revenue and the number of operations for
each price are reset to zero. The display will show
'rSt' acknowledging that the log data was reset.
The log number will be incremented to next value.
The short should be removed whilst the display
shows ‘rSt’.
NOTE: If the coin validator By-Pass inputs are
energised and the Audit Log input is shorted as for
normal data retrieval the log of the free operations
will be displayed.
OPERATING PARAMETERS
The validators have a number of other adjustments
that can be field adjusted, such as the length of
time of the output relay pulse. These adjustment
are application specific and may therefore have a
different effect on each type of unit.
In this regard even the price adjustment procedure
may vary between unit types and details should be
attached to the side of the coin validator.
For clarity on these matters please refer to
Abberfield Industries technical support.

SERVICE
MAINTENANCE
DISASSEMBLY
There are three active parts to the coin validator,
the control unit, power supply and face plate. The
control unit plugs into a display circuit board
forming part of the centre plate and power supply
on the opposite side. This assembly is held
together by two security screws, one from each
side of the unit. They form one assembly, covered
by a single serial number.
PROCEDURE
1. Using a neat fitting bladed screwdriver,
remove the right-hand plastic holding screw
located under the ledge on the right side.
2. Remove the identical left-side screw located
at the top of the left moulding.
3. The two side mouldings are now free to slide
off the middle fascia moulding. They are
removed by pulling directly backwards from
the fascia.
CLEANING OF COIN TRACK
After considerable use there may be a build up of
dirt on the coin track that impedes the flow of
coins and the validator will need opening for
cleaning. Also foreign objects placed in the
validator which do not pass through the system
will need to be cleaned out. To disassemble
remove the two security screws, one each side of
the validator. These are clearly marked with the
control board screw being at the top and the other
screw being at the bottom on the other side. The
control board mechanism can then be withdrawn
by pulling backwards. When cleaning the coin
track it is important to ensure that the two optical
sensing holes are not filled with dirt. Clean with
industrial alcohol or methylated spirits. Take care
not to leave a residue in the optical sensor holes
but do not use a pin or similar to clean into the
holes as the optical lens may be scratched.
NOTE: Care should be taken in reassembling the
validator to ensure that the pins on the front
display board make proper physical connection
into a mating socket on the control board.
ERROR MODE

As well as validating coins the device can control other machines via a number of inputs and outputs.
Special software programmes can be provided to meet specific industry or customer needs. Then the
instruction label each side of the coin validator changes to satisfy the specific application. Two typical
applications are for photocopier control and car park boom gate control and many others are possible.
