Phase 6 OPL System Diagnostics ___
IMPORTANT: You must disconnect and lockout the electric supply and the gas supply or the steam supply before any covers or guards are removed from the machine to allow access for cleaning, adjusting, installation, or testing of any equipment per OSHA standards.
All major circuits, including door, microprocessor temperature sensor, heat and motor circuits are monitored. The Phase 6 OPL microprocessor controller (computer) will inform the user, via the L.E.D. display of certain failure codes, along with indicators both in L.E.D. display and at the output of each relay (and door switch circuit) to easily identify failures.
Diagnostic (L.E.D. Display) Failure Codes
SAIL SWITCH FAIL – This routine will prevent start up on the machine unless the sail switch is in the correct position. If the sail switch is closed prior to start up the display will read “SAIL SWITCH FAIL” along with an audio indication.
No AIRFLOW – If the sail switch opens during cycle operation the display will read “No AIRFLOW” along with an audio indication. The machine will continue to run with no heat for 3 minutes or until the temperature drops below 100º F (38º C). Upon failure the machine will shut down and display “No AIRFLOW” with an audio indication.
bURNER SAFETY FAIL – Routine monitors the temperature above the burner. If the burner
dRUM SAFETY FAIL – This routine monitors the tumbler temperature if the tumbler
No HEAT – This routine monitors the burner ignition. If the burner misignites (does not light) the ignition module will check to see of the microprocessor program has any retries left. The standard retry count is 2. If the module notices that there are retries left it will purge for 1 minute then try to ignite the burner again. The ignition module will try this for a total of 3 times or until there are no retries left. If the burner does not ignite after 3 attempts the L.E.D. display will display the error code “no heat” with an audio indication. When this occurs the machine will run with no heat for 3 minutes or until the temperature drops below 100º F (38º C).
IMPORTANT: For other countries, such as Australia, the retry count may not apply due to local approvals.
