Battery Voltage Out-of-Range
If the battery voltage is out-of-range, the instrument revision and the current software/firmware
version appears on the front panel display for about five seconds (refer to Figure 1, page 4),
followed by the appropriate error message, rather than advancing to the default
Pressure and
Position
display screen (refer to Figure 2, page 4).
If the battery voltage is below 11 V, the screen displays:
***Battery is low***
Press key to continue
Figure 3: Battery Voltage Low Message
If the battery voltage is above 15.5 V, the screen displays:
***Battery is high***
Press key to continue
Figure 4: Battery Voltage High Message
The system allows for continued operation when the battery voltage is out-of-range, since your
process may not require that the battery voltage level be addressed immediately. To continue
operation, press any key to advance to the default
Pressure and Position
display screen.
Note
It is important to note that in addition to supporting the controller’s valve
position, the battery back-up feature powers the controller, and any
pressure transducer or valve connected to it.
