10. Install CommLink and power-up. At this point you are ready to begin commissioning
the system. It is preferred, though not necessary, to use a PC with Prism software to
assist in the commissioning process.
11. Start with the first controller on the communication loop or in multiple loop systems;
start with the MiniLink or with the System Manager. Plug in the Communication
terminal then plug in the Power terminal.
12. Observe the LED indicator for the blink codes as outlined in the troubleshooting
section of the manual. The blink code will first verify the address, then the operation.
If the address is incorrect, reset the dipswitch, then reapply power to the controller.
13. 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 com-
municate, verify wiring, voltages, etc. in accordance with the troubleshooting section
in the system manual. Do not proceed to the next device until you are properly com-
municating with the current device.
Continue this process until all controllers are connected and properly communicating.
By following the above steps and procedures, your installation will be much faster and
trouble free. 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.
