Once a VCB (Voltage Control Box) block has been assigned in a Nexia configuration, and the VCB device (with potentiometers attached) is connected to the Nexia Remote Control Bus, the potentiometers can be calibrated for accurate tracking of levels (see Device Maintenance).
|
|
The first screen encountered in this process allows for the selection of the potentiometer Channel to be calibrated. Channel numbers correspond to the Analog potentiometer connections on the VCB itself. Only one potentiometer Channel can be calibrated at a time, and only Channels with potentiometers actually connected will be available. |
|
|
Once the Channel has been selected, this screen will prompt the user to adjust the corresponding potentiometer (on the selected Channel) to its maximum (highest) physical setting, then select "Next". |
|
|
Once the maximum potentiometer setting has been recorded, this screen will prompt the user to adjust the same potentiometer to its minimum (lowest) physical setting, then select "Next". |
|
|
When maximum and minimum potentiometer settings have both been recorded, this screen will indicate the voltage measurements and prompt the user to either accept these values or re-calibrate. "Finish" will return to the Channel selection screen. |
NOTE: The entire range of level adjustment assigned to a potentiometer will be controlled by the voltage range measured during calibration. If the potentiometer is not calibrated, or is calibrated incorrectly, accurate control of the intended range of levels may not be achieved.
