5. SWITCH PROGRAMMING.
5.1. Tolerances.
The selector is factory programmed to recognise the coins indicated on the unit’s
label. Coin identification parameter margins can be modified individually by adding a
certain tolerance.
.
The following intervals can be set:
• Zero tolerance (factory settings).
• Minimum tolerance. (+ 10%)
• Medium tolerance. (+20%)
• Ample tolerance. (+35%)
Following is a description of the procedure to carry out such programming.
5.1.1. Programming tolerances using switches.
è The procedure is as follows:
1. Disconnect the selector (remove the connecting cable) or turn off the
machine that provides the selector with its power supply.
2. Move switches 1, 2, 3 and 4 to the ON position.
3. Apply the power supply (connect the connecting cable or turn the machine
on).
4. Move switch 1 to the OFF position.
5. Move switch 2 to the OFF position.
6. Move switch 3 to the OFF position.
7. You will now be in tolerance programming mode. Use switches 1 and 2 to
indicate the tolerance to be established for inserted and recognised coins:
SWITCHES
1 2 3 4
TOLERANCES
OFF OFF OFF ON Zero tolerance.
ON OFF OFF ON Minimum tolerance.
OFF ON OFF ON Medium tolerance
ON ON OFF ON Ample tolerance
OFF OFF OFF OFF End tolerance programming procedure
(acceptance electromagnet moves
twice).
• Example 1: Program the 1 euro coin with medium tolerance.
o Set SW.1 = OFF and SW.2 = ON.
o Insert the 1 euro coin. When it is recognised, the tolerance
will be programmed.
o If you do not wish to program tolerances in other coins, move
all switches to the OFF position, the selector will move the
acceptance electromagnet twice.
8. To exit this programming option move all switches to the OFF position. The
selector should move the coin acceptance electromagnet twice to indicate
that you have exited programming.
