The following steps are a quick means to get the PT-Link II LON-3
®
operational for many simple installations. This quick start depends on
the ability of the front end to accurately and successfully obtain the
required information directly over the LON
®
connection. If the front
end cannot successfully do this, it will be necessary to manually obtain
an XIF file from the PT-Link as described on
page 7
in the
PT-Link
II LON-3 Technical Guide
and then to manually commission the PT-
Link II LON-3
®
device.
1. Familiarize yourself with the PT-Link II components
(
Figure 1
).
NOTE:
The DIP Switches should be left in their
default positon which is all OFF. They are not used in this
application.
2. Connect your PT-Link II LON-3
®
to the Unit Controller on
your system (only one) and connect your PT-Link II to the
LON Network (
Figure 2, page 3
).
3. Power up the PT-Link II LON-3
®
with an appropriately sized
isolated 24 VAC power. (Note that the Unit Controller
should already be powered up and running). Do not use the
same power for both the PT-Link and the Unit Controller,
improper wiring of these two devices on the same power
source will cause damage to both the PT-Link and the
Unit Controller as they do not have isolated communications.
4. Allow at least 3 minutes for the PT-Link II LON-3
®
to learn
internally all its information and prepare the data tables; after
this point, use the learning capabilities of your front end to
discover the PT-Link device on the LON network and
subsequently to discover the points provided by the PT-Link
gateway.
