Location Identifier
Unit Identification Tag
The unit identification tag is factory
mounted and provided for easy identifi-
cation of an installed unit. It contains
model number, tagging, and location
information.
The unit identification tag remains per-
manently affixed to the unit for identifi-
cation purposes. The bottom portion of
the tag provides pertinent information
that can be written to in building plans
or in the
“Appendix—Location
Identifier” on page 48. This provides
identification history about the unit’s
location for quick reference.
These tags provide information about:
• unit serial number (A)
• NID (neuron identification number)—
The NID is similar to the serial number
of the unit but is specific to the identifi-
cation of the Tracer ZN524 unit con-
troller circuit board
(B)
• unit location—The location identifica-
tion is a customer defined, clear
English description, of the unit’s physi-
cal location. This is a 27 character
description, including spaces, of the
location. For example, if the location
identification for a unit is “Conference
Room 101”, the ZN524, Rover (the Trane
Loop Controller service tool), and Tracer
Summit, will recognize this clear
English description.
(C)
If location identification is not defined,
it will default to the unit serial number.
This unit identification tag provides
some information so the user has mul-
tiple references to the unit. The blank
location is provided for field modifica-
tion in case the unit is moved from the
initial location.
Winking
Winking a device causes the green sta-
tus LED on the device selected to blink
at a rate of twice per second for
approximately 10 seconds. This feature
is useful when a discrepancy in device
location exists. As part of the trou-
bleshooting process, one person can
wink the device while another can
observe the blinking and verify the
device’s physical location.
Important! If the status LED on the
ZN524 does not blink, the device
may not be communicating or it
may not be the device you selected
according to the stored address.
A Tracer ZN524 unit controller may be
set to wink by pressing zone sensor On
button for 5 seconds and using Rover,
Trane’s communication service tool or
the Tracer Loop Controller.
