Setting Contact On/Off Alarms and Delay
The on/off contact sensing is set up in the sub-menu. See page 13 for more info on
setting those. However, the delay time before sending an alarm is set on this page.
Many delays are used on switch and contact functions.
Temperature:
delay alarm to ignore defrost cycle. Typically 30-45 minutes.
Door Position:
delay alarm to allow door to be open for a period. Typically 5 minutes.
Refrigeration Leak:
delay to assure that genuine leak is present. Typically 15 minutes.
Set delays carefully. A short delay causes false alarms, a long delay may mask prob-
lems.
