IDX Xeptor Field Test Procedure

IDX Xeptor Bench Test Procedure

Click For: X-10 & X-50 V3.0 Firmware X-20 & X-60 V4.0 Firmware

Introduction
At power up reset, all Xeptors perform a series of self tests. If it passes all tests, and if rotary switch SW2 is in position 0, the indicator LED turns green and normal operation commences. If any of the self tests failed, the indicator LED repetitively flashes red/green. If the Xeptor is 'Inhibited" the LED will flash amber. All Xeptors were designed with built in field test and diagnostic capability to aid in troubleshooting problems away from the test bench. You can determine what has caused a failure by accessing rotary switch SW2 in the lower right corner of the circuit board and selecting positions 7, 8, 9, A, B, C, D, or F and observing the color of the indicator LED. The descriptions of each field test function additionally include expected oscilloscope waveforms which may be useful in a test bench environment. These waveforms and descriptions are dscribed below separately for V3.0 and V4.0 firmware. Remember that in order to return the Xeptor to normal operation, it is imperative that the SW2 be returned to position 0.

X-10 & X-50 V3.0 Firmware

Test #7
Turn SW2 to position #7. Test #7 performs a checksum of the memory, both the program ROM and the non-volatile operating parameter EEPROM. The LED will be green if the test is passed and will flash red/green if the test fails. Unless one of the chips has physically failed, the failure may likely have been caused by power interruption in the middle of writing parameters to the EEPROM after a learn cycle or during a download of parameters over the serial communication port. To clear this problem either repeat the parameter download procedure or re-learn any coin types to be accepted. This will repair the checksum and this test will them pass.

Test #8
Turn SW2 to position #8. Test #8 performs a check on the optional credit sensor optics just above and below the gate relay rake which verify that the coin passed in the proper direction with the proper timing. If there are now credit sensors installed, the LED will flash amber to warn that this function is not available. If installed and operating properly, the LED will be green. When a coin interrupts either sensor beam the LED will turn red and the ramp-down waveform extends further to the right.

Test #9, and #A: X-Mark Optics Test
Tests #9, and #A perform a check on the ability of the X-10 or X-50 to correctly read an X-Mark on a token. Test #9 checks the X-Mark reading optics on the back side while test #A checks the X-Mark reading optics on the front side. When operating properly, the LED will be green when there is no X-Mark detected and red when an X-Mark is presented and detected. There are two X-Mark detectors on each side of the coin chute and detection by either one of them will cause the LED to turn red.

Tests #B, #C, and #D: Diameter Optics Test
Tests #B, #C and #D perform beam strength tests on the three optical thru-beam sensors used to measure coin diameter. Test #B checks the bottom beams, about 1.6" from the coin chute top. Test #C checks the middle beams, about 1.3" from the coin chute top. Test #D checks the top beam, about 0.4" from the coin chute top. When operating properly, the LED will be green when the beams are not blocked and red when they are blocked or otherwise non-functional. The ramped-up waveform extends further to the right as the beam becomes blocked.

Tests #E and #F: Inductive Coil Test
Tests #F and #E perform a check on the inductive coils operated in both series aiding and series opposing modes. When operating properly, the LED will be green with no coin between the sensor coils, and red with an inductively lossy coin between the sensor coils. If no coin is present and the flat cable to the rear box is disconnected or the circuit is otherwise non-functional, the LED may flash red/green twice per second or turn red.

Test #7
Turn SW2 to position #7. Test #7 performs a checksum of the memory, both the program ROM and the non-volatile operating parameter EEPROM. The LED will be green if the test is passed and will flash red/green if the test fails. Unless one of the chips has physically failed, the failure may likely have been caused by power interruption in the middle of writing parameters to the EEPROM after a learn cycle or during a download of parameters over the serial communication port. To clear this problem either repeat the parameter download procedure or re-learn any coins to be accepted. This should repair the EEProm checksum and this test should hopefully then pass. If problems persist, call the factory for assistance.

Test #9, and #A: X-Mark Optics Test
For X-20 Series: Test #9 and #A perform no task and only causes the LED indicator to flash amber indicating there is not test function available in this position.
For X-60 Series: Tests #9, and #A perform a check on the ability of the X-60 to correctly read an X-Mark on a token. Test #9 checks the X-Mark reading optics on the back side while test #A checks the X-Mark reading optics on the front side. When operating properly, the LED will be green when there is no X-Mark detected and red when an X-Mark is presented and detected. There are two X-Mark detectors on each side of the coin chute and detection by either one of them will cause the LED to turn red.

Tests #E and #F: Inductive Coil Test
Turn SW2 to positions #E or #F. Tests #E and #F perform a check on the inductive coils operated in both series aiding and series opposing modes. When operating properly, the LED will be green with no coin between the sensor coils, and red with an inductively lossy coin between the sensor coils. If no coin is present and the flat cable to the rear box is disconnected or the circuit is otherwise non-functional, the LED may flash red/green twice per second or turn red. There are two damped sinusoids in each of the figures below. The narrower one at a higher frequency and the wider one at a lower frequency. Only the envelope of the waveform is shown below.
