Section 3 Troubleshooting Electronic Control (Models EA2820*, EA2821*, EA2920* and EA2921*) 26. AUDIT SWITCH FUNCTION ANALYSIS TE: For instructions on performing tests, refer to programming manual. Incorrect audit counts: Coin drop. Service door. Coin vault. Cycle. TE: Usually review two consecutive audit reports before sending service personnel to investigate. Remember, the audit system may be detecting tampering of the EC unit. In audit report analysis, the EC computer operator will have to determine, from the audit reports, what the servicer should examine on the EC units. If the servicer cannot find a particular problem, consult the appropriate audit reports for further analysis. Coin drop diagnostic test "Coin Drop Input Test" does the drop pass the test? Service door diagnostic test "Service Door Opening Test" does the door pass the test? Coin vault diagnostic test "Coin Vault Opening Test" does the vault pass the test? Cycle test Run a complete wash cycle and review the manual audit or Micro-wand "Display Counts" does the cycle counter advance? Check wiring and connections. Replace coin drop. Exit diagnostic test The audit coin count will not advance in the diagnostic cycle. Micro-wand or manual EC control audit will have to be accessed to determine whether audit counters are advancing. Is the audit coin counter advancing? Check wiring and connections. Replace service door switch. Investigate Tampering. Service door and mach cycle var reports. Investigate Tampering. Coin vault and service door opening reports. Machine/cycle var reports. Check wiring and connections. Replace coin vault switch. Investigate Tampering. Coin vault and collection reports. Replace electronic control board. Investigate Tampering. Service door and mach cycle var reports. TE: In the cycle audit test, the cycle count will not advance on a "rapid advance" cycle. The manual control audit or Micro-wand "show counts" will have to be accessed to determine whether audit counters are advancing. Also, the cycle count does not activate until the end of the cycle. Check for proper wiring and connections. After wiring has been confirmed correct, replace electronic control board. D216S 30 Copyright, Alliance Laundry Systems LLC DO T COPY or TRANSMIT 36007
