Problem

• Check LED for power-on indication.
• Check LED for Inhibit condition.
• Check LED for component fail condition.
• Verify rotary switch SW2 under cover is in position 0 = RUN.
• Press pushbutton SW1 under cover to verify gate relay actuates.
• Verify with HyperTerminal or the Xaminer that the coin you are using is programmed into one of the coin memories, or try to manually program the unit for your specific coin again (note: secured units may require an X-Key or Coin Selector to enable manual programming of coins).

• Verify that power wires are not holding coin chute partly open.
• Verify that gate relay wires are not holding coin chute partly open.
• Verify that the coin chute is reasonably clean.
• Verify that thickness and diameter settings are correct.
• If specific coins are always accepted and other specific coins are always rejected you may actually have two different sets of coins that look alike. This is not uncommon with multiple deliveries of tokens, and is (for example) a real problem with Canadian currency. Program each coin variant into a separate coin memory.
• Verify that the gate relay rake is not bent and clears coin chute when retracted. Use a small screwdriver to hold the rake arm to magnet coil. Check end position of the rake in the coin chute.

• It may be programmed for those other coins. Erase all of Coin Memory and reprogram the desired coins, or use HyperTerminal or the Xaminer to determine which Coin Memories to erase.
• If the bad coin is very similar to your desired coin, program the bad coin as an Unwanted Coin.

External Credit Optics: The Xeptor sends the Sense Pulse to the machine's credit optics to enable them for a short period of time to detect accepted coins. Assuming the Xeptor really did accept the coin, a Sense Pulse will have been generated. There are three possible causes for the Xeptor not generating a Sense pulse and the machine stealing the coin. 1) If a wire is broken of the transistor driver is dead, there may be no Sense Pulse for the external Credit Optics to receive and the machine may ignore the coin rather than produce a coin-in-error, thus steeling the coin. If this is the case, it will happen a lot, or always, depending on if the problem is intermittent or permanent. 2) It is possible on an X-10 or X-22 that if the coin is a fairly large coin and the gate relay spring is not tight enough, a coin that should be rejected could smack the closed gate in such a way as to bounce it open just long enough to slip past it. You can test for this possibility by turning off the power to the Xeptor and seeing if any coins still go down the accept path. If this is the case, the spring tension is probably too low. Factory calibration of the spring tension may have been changed by inadvertent bending by rough handling of the Xeptor. This problem can usually be fixed by bending the tab holding the spring so as to further stretch the spring. 3) There could be a problem with the machine's credit optics causing them to not give proper credit. You can determine using HyperTerminal or the Xaminer if the Xeptor has intended to accept the coin or reject the coin, and if it was intentionally accepted but the machine did not give credit, the machine's credit optics should be checked.

Fast Fed Coin Stolen: If coins fall through the Xeptor with a gap smaller than .25" between them at the gate relay (note: at 10 coins per second there is generally 1.5" between coins, but non-uniformity in fast coin feeding and coin bouncing can cause them to be closer) it is possible that if the trailing coin is to be rejected, it will be impossible to get the angled gate relay rake between them, and thus the bad coin will flow through without having generated a Sense Pulse for the external Credit Optics. This situation will generate a Tilt output for the Xeptor if it has built-in Credit Optics and assuming the machine is responsive to this signal.
 

LED Color

Red Or Orange

Normal color at the start of, or during, the Coin Learn Procedure.
For X-20, X-22, and X-60 with V4.0 firmware:
·         Red indicates there is no prior coin in the selected Coin Memory location.
·         Orange indicates there is a prior coin signature in the selected Coin Memory.

This indicates that the Xeptor has been "Secured" from manual coin programming unless an "Enabled" X-Key or Coin Selector is connected to the serial port. In SW2 position 0 (Run) you should also see a short red flash in the otherwise green LED because it is Secured.

This normally occurs as you drop each of the 6 sample coins during the learn procedure after initiating it by pressing SW1 one or more times.

Red / Green
Alternating

This normally occurs for about two seconds at the end of dropping the 6th sample coin to indicate that all sample coins have been registered and the data saved.

Proper Alignment Is Critical
Failure to have proper mechanical alignment may lead to either coin jams or sporadic machine tilt/error signals. IDX Xeptors always position coins in the center of the coin chute (as opposed to edge referenced methods used in simple comparators) in order to achieve precision diameter measurement and separately measure edge and center metal alloys on bimetal coins. This difference in coin positioning requirements can sometimes be the source of an alignment problem when converting from a simple comparator to an IDX Xeptor. One way to ensure proper alignment is to order the machines form the OEM with IDX Xeptors already installed. For retrofits, one may sometimes correct small alignment by repositioning or bending the existing bracket. In most cases, the machine OEMs actually have more than one bracket style and coin-head style in order accommodate all of the minor mechanical variations in coin acceptors available in the market. Some of them are listed below for your reference.

Verify Alignment With Power Off
One of the best ways to verify proper alignment is to deposit coins into the machine with no power to the coin acceptor so you can observe how the coins flow through the entry and exit of the coin acceptor. You must make sure that the coin may easily enter and exit the coin acceptor with no possibility of catching a coin edge due to front/back alignment problems, and with no significant right/left jog at entry or exit. To verify there is not problem in the accept path, you can use a wad of paper to hold the accept gate open.  

The Right Bracket And Coin-Head May Help
Older retrofit machines sometimes have coin acceptor brackets and coin-heads that do not have the proper precision of alignment required for newer precision coin acceptors. Our expert field sales staff can help you with identification of bracket part numbers available from slot machine manufacturers for update retrofits that eliminate mechanical alignment problems.
