dor - How the 'Door Open' alarm works
When a cooler door is open for longer than normal, the SCS Controller can trigger and display an alarm to alert the site manager or staff.
In most situations, simply closing the door again will normally clear the Door Open (dor) alarm and return the cooler to normal operation. If the door is loose or 'sagging' it may require further physical adjustment by a refrigeration technician.
SCS Controllers with FW versions prior to 1574 used fault code "1" rather than "dor" for this alarm type.
