Modular Service Tool Alarm Search
NOTE:
When
you
press
the
button on the Modu-
lar Service Tool, it will search only the unit ID that
you have entered; therefore, you must search each unit
individually to access all alarms for that controller.
To search for alarms, press
< ALARMS>
while on any screen but the
Main Screen
. The Unit Selection Screen will be displayed.
Enter Unit Address
Then Press Enter
Selected Unit #_1
Press Down
Enter the Unit ID of the controller the Service Tool is connected to
and press
. 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.
One of the following screens will appear:
VCC-X V.XXX
NO ALARMS
VCC-X V.XXX
ALARMS PRESENT
SCROLL DOWN TO VIEW
Press
<
>
to scroll through all the alarms for the controller that the
Modular Service Tool is connected to.
To clear any alarms that are found, you must fi x the problem indicated
in the alarm. Once the problem is fi xed, the alarm will clear from
the screen the next time the unit is polled.
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.
Enter Unit Address
Then Press Enter
Selected Unit #160
Press Down
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:
VCC-X V.XXX
NO OVERRIDES
VCC-X 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. Enter the Unit ID of the MLPD of that loop.
