EFINING THE NUMBER OF PULSES ASSOCIATED WITH EACH COIN
Read chapter 4 "Preface to programming" before proceeding .
Determine the number of pulses associated with each coin, based on the coin´s value, as follows:
1. Assign a value of 1 pulse to the coin of least value.
2. Define the number of pulses for each of the other coins by dividing the value of each by that of the coin of
least value.
Example 1: if 3 coins of the values €0.50, €1.00 and €2.00 are used, you will have 1, 2, 4 pulses respectively.
Example 2: if 5 coins of the values €0.10, €0.20, €0.50, €1.00 and €2.00 are used, you will have 1, 2, 5, 10, 20 pulses
respectively.
Now observe Fig 3, where it shows 8 Lists of numbers of pulses (List 1, List 2, ... List 8). Each List is selected by a
different combination of DIP-Switches.
You must find the List that contains all the numbers of pulses of the various coins defined previously.
Note that List 1 or List 2 will satisfy the majority of cases; in fact, it also contains all the numbers of pulses of the 2
examples mentioned above.
This multi-coin acceptor has 8 Memories and in each Memory the coin to be recognized can be memorized. The 8
Memories are abbreviated as follows: Mem1, Mem2, Mem3, ... and Mem8, and are shown in the left-hand column in
Fig 3.
Once you have identified the List and defined the number of pulses of each coin, the corresponding Memories where
the coins get memorized should be set. For example, if List 1 is selected and the coin is given 2 pulses, that coin
should be memorized in Memory 5 (Mem 5).
Example 1: if 3 coins of the values €0.50, €1.00 and €2.00 are used, you can select List 1 and register the coins in the
following Memories:
€0.50 = 1 pulse. Register this coin in Mem3 or Mem4
€1.00 = 2 pulses. Register this coin in Mem5 or Mem6
€2.00 = 4 pulses. Register this coin in Mem7 or Mem8
Example 2: if 5 coins of the values €0.10, €0.20, €0.50, €1.00 and €2.00 are used, you can select List 2 and insert the
coins in the following Memories:
€0.10 = 1 pulse. Register this coin in Mem1
€0.20 = 2 pulses. Register this coin in Mem2
€0.50 = 5 pulses. Register this coin in Mem3 or Mem4
€1.00 = 10 pulses. Register this coin in Mem5 or Mem6
€2.00 = 20 pulses. Register this coin in Mem7 or Mem8
Please note that 1/2 pulse corresponds to Mem3 List 7; therefore, 2 coins must be inserted in order for a pulse to
occur.
A single coin will not cause any time to be loaded to the Timer.
If in List 1 you do not find the desired proportion between the values of the coins and the number of pulses, you can
select a different List from the 8 ones available.
Please note that in some Lists there are two Memories to which the same number of pulses correspond; these
Memories are useful for programming 2 different coins of the same value.
At the end of this chapter the following information will be presented:
1. The List you want to use. Setting the DIP-Switches for selecting the List of choice can be carried out at the end
of chapter 6, after programming the coins.
2. Into which Memories you should insert coins.

ROGRAMMING THE COINS TO BE ACCEPTED
Once you have defined to which Memories the various coins should be assigned (see chapter 5), follow the 5 steps
below:
1. Deactivate the device.
2. Set the DIP-Switches located on the multi-coin acceptor (see Fig 2) to select the Memory in which you wish the
