ALARM CODES
7-Segment Display
The left hand window shows the cabinet wall temperature.
The right hand displays show the probe temperatures during a blast cycle, and are normally blank during store. If a probe fails it will indicate pf (probe failure) during a blast.
Cab temp window also acts as a count up timer in probe blast.
If there is an alarm condition, the top probe display will show an alarm number a0 to a7 during store (see table below), but will still show the probe temperature during blast.
| Alarm Condition | |

a0 | AIR ON SENSOR FAILURE | |

a1 | WALL SENSOR FAILURE | |

a2 | FIN SENSOR FAILURE | |

* (Top Display On Front Panel Used For 3 Probe Systems)
Note: for each probe only one audible alarm and alarm printout is allowed to be issued each day. This is to prevent excessive paper use and noise nuisance in the event of an intermittent probe failure. However, repeated probe failures are displayed on the probe display window, (top window in the case of 3 probe panels)
