Procedures (Continued)
10) With no power connected, wire controller according to wiring diagrams and
in accordance with local codes. Never apply power until you have completed
these procedures in accordance to all system instructions.
11) After completing all wiring connections, unplug the terminals for power and
communications. Always unplug the communications loop first and then the
power. When reconnecting the wiring, connect the power first and then the
communication loop.
12) Repeat Steps 8 through 11 until all devices have been wired and the power
and communication terminals have been unplugged.
13) Install the CommLink and power it up. At this point, you are ready to begin
commissioning of the system. It is preferred, though not necessary, to use a
PC with Prism™ software installed to assist in the commissioning process.
If you are not using a PC, the System Manager is required to be connected
and powered up in order to communicate with the system.
14) For the CV system, start with the first CV controller on the communication
loop. Plug in the Communication terminal and then plug in the Power
terminal. With the CV-EX multiple loop system, start with the MiniLink.
Plug in the Communication terminal and then plug in the Power terminal.
With the CV-EX system, confirm correct addressing of the MiniLink by
verifying its blink code. Then connect the first CV controller on that local
loop and proceed to the next step.
15) Check the CV Controllers for correct communications and addressing by
observing the LED indicator for the blink codes as outlined in the trouble
shooting section of the manual. The blink code will first verify the address
and then the operation. If the address is incorrect, reset the address switch,
and then reapply power to the controller.
16) After each controller is connected and completes its initialization sequence,
use the PC or System Manager to verify communication to that device. If you
cannot communicate, verify wiring, voltages, etc. in accordance with the
trouble-shooting section in the system manual. Do not proceed to the next
device until you are properly communicating with the current device.
17) Continue this process for each CV Controller on the loop and repeat the
process on each loop for the CV-EX system until all controllers are
connected and properly communicating.
Remember that each controller only contains one puff of smoke. Making sure that all
wiring terminations and voltages are correct prior to applying power to a controller will
ensure that you don’t use that one puff up.
