Auto-Zone CV & CV-EX
Section 4
Start-Up and Troubleshooting 4-15
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) Continue step 8 until all devices have been wired and the power and commu-
nication 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.
The System Manager is required to be connected and powered up if you are
not using a PC, 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 then plug in the Power terminal
With the CV-EX multiple loop systems; start with the MiniLink. Plug in the
Communication terminal then plug in the Power terminal. With the CV-EX
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 ob-
serving the LED indicator for the blink codes as outlined in the troubleshoot-
ing section of the manual. The blink code will first verify the address, then the
operation. If the address is incorrect, reset the address switch, 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 trou-
ble-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 con-
nected 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
insure that you don’t use that one puff up.
