Chapter 3 - 6 Installing VO2 Analog Output Boards - icemeister.net

Inspection of theInstalled VO2When a VO2 Variable Output Board is ready for operation, you should be able to observe the following,proceeding clockwise around the board from the power terminal strip:1. Power (12 VAC or 15 VDC) has been connected to the “12 VAC” terminal strip.2. The status LED should be blinking. If the status LED is off, there is no power to the board(check the fuses). If the status LED is constantly on (not blinking), the board is not communicatingwith its AKC 55. Make sure the AKC 55 has been configured for this board; ifconfigured, there will be information in at least one of the Board and Points screens; you caninvestigate, and supply configuration information, if necessary, by following the proceduresdescribed in Section IV of this manual.3. The service LED will normally blink briefly when the network is scanned, but if the serviceLED remains steadily on, the VO2 board is defective and should be replaced.4. The address switches have been set to a valid address.5. Loads are connected to one or both of the pair of output terminals.6. Connection has been made to the I/O network of an AKC 55 at the “NETWORK” terminal.7. If this board is the last node on a run, make sure that it is terminated by using one of theterminators supplied with the AKC 55.AKCESS System Manual RC.IU.B1.22 4/99.1 3-27
