13. Adjustable Coin Security
The security of an individual coin/token can be adjusted using the 6 way DIL switches.
Switch 1
Allows sensor windows to be increased or decreased. (ON = increase
windows / decrease security, OFF = decrease windows / increase
security)
Switches 2, 3, 4
Determines the number of counts to be added or removed from the
sensor windows (SW2 = MSB, SW4 = LSB). See
below.
Switch 5
Not used for adjusting coin security settings = OFF.
Switch 6
Enables coin security mode = ON.
For Example:
To increase the sensor windows / decrease the security on a £1 coin
4
by 2 counts
5,6
the
following procedure should be followed:
Switch off the power to the SR3.
Set the 6 way DIL switches to:- (widen, 2 counts, security)
SW1
SW2
SW3
SW4
SW5
SW6
ON
OFF
ON
OFF
OFF
ON
Switch on the power to the SR3.
Press the reject lever within 20 seconds and check the LED turns RED.
Insert a £1 coin.
The LED now flashes GREEN.
Press the reject lever again.
The LED will now turn RED then GREEN.
The security has now been changed.
Set ALL the switches to the OFF position.
Notes:
4
The coin channel must be ENABLED for changes to be programmed.
5
+n counts will add n counts to the upper limits of the sensor windows and subtract n
counts from the lower limits of the sensor windows for the coin channel selected. i.e.
+2 counts will actually make the sensor windows a total of 4 counts wider on the coin
channel selected.
-n counts will subtract n counts from the upper limits of the sensor windows and add
n counts to the bottom limits of the sensor windows for the coin channel selected.
i.e. +3 counts will actually make the sensor windows a total of 6 counts narrower on
the coin channel selected.
6
If 2 counts were not enough and 3 counts were actually required, the procedure has
to be repeated for +3 counts (NOT an extra +1 count).
