Coin Jam
If the measuring system identifies a coin, but measuring is concluded via “timeout”
instead of the correct measuring procedure (coin leaves coin selector passing the
receipt light barrier or the return), this will be interpreted as “coin jamming”.
Via the parallel interface, the coin selector can give a signal for coin jamming to
the machine. The customer can choose any of the coin output channels or a
combination of channels through which coin jamming will be signalled. This can be
programmed by the factory. The information is emitted by a minimum impulse
width of 200 ms. The machine is able to distinguish between coin jamming and a
normal receipt signal, as it can recognise the different width and (or) identify a
combination of simultaneously arranged coin output lines.
The following coin jam signals are possible:
-
Coin jam 1 (in the measurement system)
-
Coin jam 2 (not used on EMP 500 v4)
-
Coin jam 3 (between the measurement system and the acceptance light
barrier)
-
Coin jam 4 (in the acceptance light barrier)
-
Coin jam 5 (not possible with the EMP 500 v4)
-
Coin jam 6 (not used on EMP 500 v4)
If a coin is still identified in the light barrier after 200 ms have passed, the
message will be repeated. During this time, coin acceptance is blocked.

The Label
The label of the coin selector has all the necessary information required by the
machine controller such as the output lines and blocking switch configurations.
The following section explains and clarifies the format and legend on the label.
