Please conform to all safety precautions before making changes to the unit. Please note that all setting / programming of our electronic coin selectors may be carried out at the factory or by any authorised "wh Münzprüfer Service Centre.

wh Münzprüfer Dietmar Trenner GmbH, Germany 2.2 Technical Manual EMP 8x0.00/04/13 v5 Programming of Coins There are a variety of ways in which the coin acceptance of the EMP 800 v5 may be programmed. The coin selector can “learn” new coin parameters, including individual tolerance requirements, with the help of the Calibration Function. Calibration is carried out either using the PC based wheasy 3 software or directly in the vending machine using the Teach mode Function (see On site programming).
Technical Manual EMP 8x0.00/04/13 v5 wh Münzprüfer Dietmar Trenner GmbH, Germany 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.
wh Münzprüfer Dietmar Trenner GmbH, Germany Technical Manual EMP 8x0.00/04/13 v5 Channels 7 and 8 cannot be calibrated with the teach mode because the DIP switches 7 and 8 are used to set the acceptance tolerance and to activate teach mode respectively. ! Only 15 blocking switches are available on those coin selectors that have been factory set with the teach mode. The coin selector will not accept any coins while it is in the teach mode.
Technical Manual EMP 8x0.00/04/13 v5 wh Münzprüfer Dietmar Trenner GmbH, Germany successful when using „broad“ tolerances (blocking switch no. 7 OFF), teaching could be still possible using the narrow tolerances. 10. The teach mode is deactivated via blocking switch no. 8 (OFF). When the teach mode is deactivated, all blocking switches may then be used for individual coin blocking with the exception of blocking switch no. 8. 2.2.

The actual cloning process takes about 15 seconds after the OK button has been pressed. 2.3 Coin Selector Output Signals There are 6 open collector parallel outputs (current sink) on the EMP 800 v5 10-pin connector. They can be freely assigned in any combination to the 16 master channels.
Technical Manual EMP 8x0.00/04/13 v5 wh Münzprüfer Dietmar Trenner GmbH, Germany The signal is, however, of a very short duration relative to the normal acceptance output signal (credit pulse). This preceding coin output signal pulses before the coin selector magnet is activated. The signal has a maximum width of 10 ms if the coin selector is blocked (from accepting coins) via the general blocking input.
wh Münzprüfer Dietmar Trenner GmbH, Germany Technical Manual EMP 8x0.00/04/13 v5 Figure 8 shows the acceptance of the coin after it has been identified. The sequence of events is as follows: 2.3.4.1 - The preceding signal starts on the assigned output line after the coin has been identified. - The machine controller removes the general blocking signal after 3 ms. Almost immediately, the coin selector ends the preceding signal and energizes the acceptance magnet.
Technical Manual EMP 8x0.00/04/13 v5 2.3.6 wh Münzprüfer Dietmar Trenner GmbH, Germany Parallel Output Connector (ST EMP) The parallel output connector is a 10-pin, dual row .1-inch center jack as specified by DIN 41651. The connector has the following pin out: Pin No. 1 2 3 4 5 6 7 8 9 10 2.
wh Münzprüfer Dietmar Trenner GmbH, Germany Technical Manual EMP 8x0.00/04/13 v5 In certain circumstances, the general blocking signal can also be used to block individual coins (chapter 2.3.4 preceding coin output signal – Option /S). 2.4.2 Individual Coin Blocking via DIP switches The coin selector has 16 DIP switches for individual coin blocking. Blocking is not active, that is, the coin will be accepted when the switch is in the “OFF” position. A coin will be rejected when the switch is “ON”.
Technical Manual EMP 8x0.00/04/13 v5 Figure 10 wh Münzprüfer Dietmar Trenner GmbH, Germany Window for “Coin Values” The individual fields are defined as follows: • S.Value (Calculated Coin value) The calculated coin value is stored in the coin selector. This value uses the machine controller for the determination of credit and the selector for calculating the number of inventory pulses. • Value (Actual coin value) This “value” is not stored in the coin selector.
wh Münzprüfer Dietmar Trenner GmbH, Germany Technical Manual EMP 8x0.00/04/13 v5 There are some special fields at the bottom of the window, below the heading of “Scaling.” These adjustable parameters have the following meaning: 2.6 • Scaling Factor This value is used in vending machines that communicate with the coin selector over the serial MDB protocol. The vending machine may read these values during a status request.

The coin selector can also be used in combination with many other sorter available on the market. 2.7.1 Option /X The EMP 800 v5 incorporating option /X provides a control for external coin sorting flaps. The control signals of the microprocessor are transmitted via 3 additional output lines.

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.
Technical Manual EMP 8x0.00/04/13 v5 2.10 2.10.1 wh Münzprüfer Dietmar Trenner GmbH, Germany Safety Features Coin on a String (Strimming) The EMP 800 v5 is equipped with multiple safety functions to prevent almost every coin-on-a-string manipulation. As an additional security the coin selector can signal attempts of manipulation to the machine controller. It is also possible to block coin acceptance for a programmed time in order to make further attempts of manipulation more difficult.
wh Münzprüfer Dietmar Trenner GmbH, Germany Technical Manual EMP 8x0.00/04/13 v5 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. 2.10.3 Additional External Strimming Detection (Option /Z) For certain applications an additional strimming detector to avoid manipulation is recommended, especially when working with an escrow.
