Communicating with a remote device
After Bell 202 communications have been set up (both wiring and configuration), you can connect to
the Series 3000 device using the parameters described in Table 13-5.

Description
Fault setting
None
The method used to indicate a fault alarm via digital communication. This
setting also applies to digital communication from the core processor.
Options are as follows:
setting also applies to digital communication from the core processor.
Options are as follows:
• Upscale – Process variables indicate the value is greater than the upper
sensor limit. Totalizers stop.
• Downscale – Process variables indicate the value is less than the lower
sensor limit. Totalizers stop.
• Zero – Flow rates, density, and temperature go to their internal zero
value.
• NAN (Not A Number) – Process variables report IEEE NAN. Totalizers
stop.
• Zero flow – Flow rates go to their internal zero value; other process
variables are not affected. Totalizers do not stop.
• None – Process variables reported as measured. Totalizers do not stop.
For all options, Modbus scaled integers report
Max Int + 1
