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).
To cancel the audible alarm press the ✗ button. If the alarm condition still exists the display will continue to indicate there is a fault.

THE PRINTER
If fitted and “ON”, the printer is activated after each blast cycle. The printer provides hard copy historical data of cabinet performance or warning tickets to archive or act upon.
The formats available are:
Midnight Ticket (if programmed)
At midnight a ticket is automatically printed for archiving in the morning. The midnight ticket provides the following information:
❖Time and date of printout and cabinet number
❖Cabinet temperature at time of printout
❖A graph of cabinet temperature over the preceding 24 hours
Demand Ticket
A ticket may be requested from the control panel by holding the printer ‘On/Off’ button for 5 seconds. This ticket provides the same information as the midnight ticket except that up to seven days of historical data are printed.
Alarm or Warning Ticket
A ticket is automatically printed if any condition is detected by the micro controller which may need attention.
The print function may be terminated by pressing the printer ‘On/Off’ button.
Mains Power Failure Ticket
If mains power fails for more than 5 seconds a ticket is automatically printed which gives the time of power failure and the time at which power is restored.
Sensor Failure Ticket
If the controller detects that one of its sensors has failed then a warning ticket will be printed.
