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.
