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

rejected. In this way the range of coins to be

accepted can be quickly set without needing to

reprogramme the validator. Note, after chang-

ing 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

requirements. 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.
