Figure 4 Calibration window for EMP 800 v5 coin selector

The calibration mode “fix” is intended for use with coins and coin channels for

which preset tolerance parameters are available and calibration mode “fix” is also

preset. 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 on the bottom row of

DIP switches 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 in the bottom row

corresponds to channel 1 and right DIP switch in the upper row corresponds to

channel 16.

The coin channel must be chosen after

activation of the teach mode switch 8. The

advantage is that it is not necessary to set all DIP switches to “OFF” first before

programming a particular channel.
