Modular Service Tool Override Search
When a space sensor with override option is used with any VAV/Zone
or Unit Controller, the Modular Service Tool can determine and report
any controllers that are currently operating in an override condition on
a specifi c Loop by entering a Loop ID number and then doing a search.
NOTE:
When you press the button on the
Modular Service Tool, it will search only the Loop
number that you enter; therefore, you must search each
loop individually to access all overrides.
To access the Overrides Screen, press from the
Modular Service Tool’s keypad. A screen will appear asking you to
enter the unit ID.
Unit Selection*00*
Enter Unit ID#
Selected ID#: 160
Enter the Unit ID for the MiniLink PD (MLPD) of the loop you wish
to search. and press
. The MLPD is always address 60 on
each loop. So the unit ID of any particular MLPD would be the loop
number followed by 60. In the example above, Loop 1, address 60 has
been entered. Once communication is established, the *00* message
will go away. Then
press
<  >
.
NOTE:
If the *00* remains, it indicates a communication failure
to the controller.
If communications are successful, one of the following screens will
appear:
VAV/CAV/MUA V.XXX
NO OVERRIDES
VAV/CAV/MUA V.XXX
OVERRIDES PRESENT
SCROLL DOWN TO VIEW
After the Service Tool completes its search, it will post a message to
tell you if there are overrides present. If there are overrides, press
<

>
and all units on the loop will be listed showing ‘Override: Yes or No.’
Press
again to access overrides on a different loop.
