Universal I/O Status Menu
The Universal I/O Status Menu provides diagnostic information to qualified service personnel.
The items listed in this menu will provide current status information of the Universal inputs &
outputs. If the universal I/O is configured for resistance, the value will be displayed in 1/10th
ohm scale. If I/O is configured for voltage, the value is displayed in 1/1000th volt scale.
Example: MCB-X7 (OA Damper analog output) shows a value of 3000, which translates into
3 VDC.
