1.2 Technical Data
1.2.1 The EMP 8x0.00 v5, 8x0.04 v5 and 8x0.13 v5 Coin Selector Features
The EMP 8x0.xx v5 is a 32 channel, 6-output line coin selector. Any coin may be
assigned to any parallel output channel and the length of the output pulse signal
may be set from 1 ms to 65 seconds. Only 5 output channels will be available if
one of the output lines is used for an inventory impulse.
The EMP 8x0.00 v5 coin channel can only be programmed to one parallel output
line.
Programming output pulse signals to a combination of output lines of the EMP
8x0.04 v5 is achieved through binary coding.
The EMP 8x0.13 v5 coin selector interface supports the serial multi drop bus
Protocol (mdb) and the cctalk interface. In all other respects this coin selector
functions in the same manner as the EMP 8x0.00 v5 and EMP 8x0.04 v5.
The 32 coin channels are subdivided into 16 master and 16 slave channels. The
slave channels can be freely assigned to the 16 master channels. However, each
slave channel always has the same coin value, output line and sorting value as the
assigned master channel. The slave channels are used to adjust to minting
variations or for fine adjustments in the variation of coin acceptance parameters.
The EMP 800 v5 has been designed with the ability to direct external coin sorting
flaps (Option /X). Three additional output lines can be used to sort a coin to a
maximum of 8 different sorting flaps. Each of the 16 master channels can be
assigned to one of the 8 external sorting shafts. For sorting of coins the 3-way
sorter SRT 800, SRT 810 or SRT 820 are available (see Technical Manual SRT
800). With sorter SRT 810 external sorting flaps can be controlled via coin output
lines 5 and 6.
The coin selector is equipped with safety functions including detection of “coin-on-
a-thread” (strimming) or “coin jamming”. It has also a coin tracing system as a
security provision against manipulation . Any coin jamming or drawing back of a
coin-on-a-thread would cause an alarm signal to be emitted via the serial
interfaces. The parallel interface may also be configured to signal alarms. The
alarm signal pulses are at least 200 ms long with the parallel interface so that they
can be differentiated from the coin pulse signals, normally 50 ms or 100 ms. The
coin selector monitors each coin for a proper trajectory through the coin path.
Deflections that suggest an attempt at manipulation are dealt with. An early
detection of such an occurrence will cause the coin to be rejected. Additionally, no
credit is given for a coin detected, but too late for rejection.
Enhanced safety features have been integrated into the EMP 800 product
generation, v5. Depending on the programming of the selector it is also possible to
block the coin acceptance for a maximum of 255 seconds automatically after a
manipulation has been detected.
The EMP 800 v5 series can be programmed through the serial interface. The PC
software wheasy 3 or Palm OS
®
Software whpocket 3 is available for these
procedures.
