Designation of Remote I/O Modules
When you receive a Remote I/O Module(s) in a Remote I/O Panel, it has not yet been assigned a designation (meaning it has
not yet been assigned to be Hardwired, Remote A, Remote B, etc.). The module only becomes a Remote I/O Module A (or B,
or C, etc.) or a Remote I/O Module for Hardwired Chillers after it has been commissioned into the CSM’s L
ON
W
ORKS
communications network. This assignment is accomplished at the Device Addressing screen of the CSM user interface.
To designate a Remote I/O Module(s), go to the Device Addressing tab in the CSM user interface. The Device Addressing
screen contains both a Chiller table and a Remote I/O table. To designate a Remote I/O Module, click on the Service Pin
button associated with the appropriate Remote I/O device (e.g. Remote I/O - A) in the Remote I/O table. While the Service Pin
timer is counting down, (the timer appears as a pop-up box on the screen) press down on the Service Pin button located on
Remote I/O Module. After you have assigned a module, label it for future reference. Labels are included with the Remote I/O
Panel for this purpose.
To designate a module as Hardwired, go to the Chiller table, click on the dropdown menu and change the default in the
Hardwire Selection field from MicroTech II to Hardwired. Next, click on the Service Pin button associated with that chiller.
While the Service Pin timer is counting down, (the timer appears as a pop-up box on the screen) press down on the Service Pin
button located on the Remote I/O Module. After you have assigned a module, label it for future reference. Labels are
included with the Remote I/O Panel for this purpose.
