6.33 Relay (1- 8) Output Menu – Alarm Type
This page is used to set the alarm relay set points, etc.
You may also change the Relay Control Mode here. If you do, you will have to reselect the Input
Assignment as well.
This section assumes that the Relay Control Mode is set to Alarm. Other control mode types are
described in other sections of the manual.
Alarm Condition
In the left hand column, a list of all possible alarm conditions will be displayed. Only the alarm
conditions that are possible given how your controller is configured will appear. To the right of
each type of alarm condition there will be a column labeled Critical Alarm with a choice of "Yes"
or "No". Click on the "No" radio button if you do not want that type of alarm to activate this relay.
Status
This menu is for information only, and tells you if the alarm relay is currently on or off, and if it is
on, for how much time. Possible status messages are Off, Off/Manual, On/Time counting up
(indicating how long the alarm relay has been active) and On/Time counting down/Hand (for
manual output activation).
Custom Name
This menu allows you to call the output another name if desired. Type the new name in the text
box.
On-Delay Time
In order to avoid being notified of an alarm condition that quickly corrects itself, you set a delay
time for the alarm action. If the alarm condition still exists at the end of the delay time, then the
alarm relay will activate. If the alarm condition no longer exists at the end of the delay time, no
notification will occur. Any value between 1 and 1440 minutes is acceptable.
Power-up Alarm Delay Time
In order to avoid being notified of an alarm condition that is only present because the system is
just powering up, you set a delay time for the alarm action. If the alarm condition still exists at the
end of the delay time, then the alarm relay will activate. If the alarm condition no longer exists at
the end of the delay time, no notification will occur. Any value between 0 and 1440 minutes is
acceptable.
