alarm delay (Ad)
The table below details the alarm delay (
Ad
) parameter.
display
description
Defines the maximum time the cooler door can be open before sounding the alarm buzzer.
considerations
If disabled, the door switch is also disabled.
The ems controller does not detect door openings, therefore, the ems controller does not:
l
update the self-learning matrix for door activity.
l
manage the evaporator fan management for door activity.
l
sound door alarms if the door is left open.
