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.
