System Manager NM & MM Mode Loop Search
When the System Manager is configured for Network Mode a loop search
must initially be performed for the System Manager to recognize alarms
or overrides. Also, when you have a system that has multiple System
Managers and you have one of the System Managers set to (63) Net-
work Mode for alarm and override indication, you must also perform a
loop search for that System Manager. This allows the System Manager
to be aware of all alarms and overrides for all local loops on the entire
system. .
Note: The Loop Search function is only required when using
the System Manager(s), not the Modular Service Tool.
To access the Loop Search screen, do the following. From the main
menu screen press enter to display the following screen.

The System Manager will now proceed to search all loops to find the

will display the current loop being searched and the number of loops
currently found.
Once the search is completed the following screen will be displayed.

The screen will display the number of loops found on your system. The
information will be saved into the System Manager’s memory. No fur-
ther loop searches will be required unless an additional MiniLink Poll-
ing Device is added to the Network System.
System Manager Alarm Search
The System Manager can be used to search for all active alarms on the
system. The MiniLink PD must be configured to allow for “Alarm Poll-
ing” for each controller that alarming is desired on for this function to
work. See the MiniLink PD programming section of this manual for
setting information. Press the “Alarm” key. The Unit Selection screen
below will be displayed. Enter the Unit ID of any unit on the system and
press “Enter”. This is the unit ID of where the alarm search begins. The
entire system is searched from this point.

The following screen will appear. The System Manager will search for
any active alarms on the entire system.

After the System Manager completes it’s search, it will list the first unit
on the system that currently has an active alarm. Press “Enter” to scroll

tween units with alarms.
