Using Delays

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.
The two dry contacts frequently monitor
freezer and refrigerator doors and alarm if
the door is left open for a certain time. If
▼
the value is set to zero, there is no delay.
A submenu function enables the contacts
operation.
The value is minutes until an alarm is
activated. These devices frequently monitor
refrigerator doors and alarm if the door is left
open for a long time. If set to zero, there is
no delay. A submenu function enables the
contacts operation.
