4.6 Supply Voltage
The supply voltage may be mapped as an internal analogue input. The 16 bit value
corresponds to 0-30V. There is no analogue sensitivity for this measurrment - it is only
transmitted based on the configured update time. The measurement is taken every time the
505K transmitter operates.
The supply voltage also has user-configurable setpoints to determine the Supply Low Volts
alarm. These setpoints can be set from the SetPoint option. The 905K module will shut-
down when the supply voltage reaches 90% of the “low volts” value. We recommend the
following setpoint values:
