Figure. 4 Calibration window for EMP 500 v4 coin selector
The calibration mode “fix” is intended for use with coins and coin channels for
which preset tolerance parameters are available. These parameter sets can be
seen by selecting the menu selection “Coin Overview”. Please refer to the
w
heasy
2 programming manual for more information, but as a general rule, “fix” provides
the best results when such information is already available.
The coin tolerances are automatically adjusted to the test coin set when “narrow”,
“average” or “broad” are chosen. This makes them particularly appropriate for the
calibration of new coins or tokens in the absence of coin data sets.
Each of the calibration ranges approximates coin acceptance as follows:
narrow
approx. 95%,
average
approx. 98%,
broad
approx. 99%.
Obviously, the actual acceptance rate in a vending application may vary from the
figures above. The level of variation relates directly to just how the coin set used
for calibration is typical of the coins currently in circulation.
The number of inserted coins as well as the overall number of coins required is
shown in the calibration window. The total number of required coins is determined
by the data file. Calibration automatically ends once the required number of coins
have been inserted and the procedure may now be finished or another coin
channel selected for calibration.
2.2.1.2.
Calibration Using the Teach Mode Function (Option /T)
The coin selector can be delivered with an optional teach mode function (on site
programming). The teach mode can be set up for a maximum of 14 channels at
the factory. No PC is required for the teach mode, since the necessary software is
built into the coin selector.
The teach mode is activated by setting the number 8 switch (left DIP switch block)
to “ON”. The number 7 switch of the same DIP switch block is used to set the
acceptance tolerance to “broad” or “narrow”. The “ON” setting selects a narrow
tolerance.
To start the calibration it is necessary to select a channel to be calibrated by
setting one channel switch to “ON”. The left DIP switch of the left DIP switch block
corresponds to channel 1 and right DIP switch of the right DIP switch block
corresponds to channel 16.
