IM 968-4 • MICROTECH III CHILLER UNIT CONTROLLER
Component Data
The
L
on
W
orks
communication module is a printed circuit
board with a plastic enclosure. It connects directly to the left-
hand side of the MicroTech III chiller unit controller as shown
in
Figure 3
. It may be possible that another module is also
connected to the unit controller. In this case, the
L
on
W
orks
communication module simply attaches directly to the left side
of the existing module instead of the unit controller.

Features
Service Pin
The service pin generates a service-pin message that contains
the Neuron
®
ID and the program code identification of the node.
The service pin message is used to commission the
L
on
W
orks
communication module by broadcasting it on the network
(
Figure 4
and
Figure 5
).
The service pin button is located below the enclosure just left
of the LEDs. The service pin is activated by inserting a small
tool into the button. See
Commissioning
section for details.
