coin exits the coin selector. The coin selector will not accept any additional coins
during this hold time unless they are of the same type as those then being sorted.
Optionally, the hold time can be shortened by programming at the factory. The hold
time will be cancelled by briefly activating the general blocking line. If the external
sorting mechanism can track the coin trajectory, the machine controller can signal
the coin selector to accept another coin sooner once it has been determined that a
coin has cleared the sorting mechanism.
2.7.4 Main Cash Box
The EMP 8x0.13 v5 can be set up to direct coins to a main cash box when
connected to the vending machine through the MDB or cctalk protocol. The main
cash box is then specified for all accepted coins.
The programming of the main cash box is discussed in the wheasy 3 manual in the
“Edit” chapter, under the sub-heading “Sorting Shafts.”
2.8 Coin Return
The coin selector EMP 800 v5 has a feature which will identify and give credit for a
coin, and then return it. This feature can be used, for example with test tokens. It
can also be used where certain persons, for example employees, are to receive
benefits without cost (e.g. car parking).
The setting of this function is also discussed in the wheasy 3 manual in the “Edit”
chapter, under the sub-heading “Sorting Shafts.”
2.9 Battery Operation
2.9.1 Option /B
Battery operated selectors with option /B use a piezo-electric element for the wake
up function. A coin selector with the battery operation option will not use any
current (< 5 µA) while in the stand by mode. The coin selector only turns itself on
when a coin is inserted. The coin selector turns itself back off after the coin has
been measured, passed the acceptance light barrier and an output impulse has
been released. The coin selector is on for a maximum of 800 ms while it attempts
to recognize a coin.
The activation of battery operation can be set with wheasy 3 with the
“Configuration” pull down menu. Select “B-values” and then “Mode” .
! Do not enable battery operation unless the coin selector has been
manufactured with this necessary hardware. The coin selector label
will specify the /B option if this is the case.
The EMP 8x0.13 v5 has some additional special requirements for battery
operation. These are discussed in chapter 3.3.4.
2.9.2 Option /C
An inductive switch is used for the wake up function for battery operated units with
option /C. During standby the current consumption is less than 10 µA. This option
should be considered if there might be vibrations that could wake up the coin
selector (for example table footballs). All other functions are identical to the coin
selector with option /B.
