Message Additional Status
(1)
(1) Location of the Alert in the HART command 48 Additional Status field.
Description
Supply Voltage Low Byte 8::Bit 4 The supply voltage is low and may affect
Device Operation.
Electronics Temperature Out of Limits Byte 1::Bit 2 The temperature of the electronics board has
exceeded the transmitter’s operating range.
Level Measurement Lost Byte 3::Bit 1 No valid Level reading. Reasons may be
multiple:
• No valid surface echo peak in the measuring
range.
• Incorrect transmitter configuration.
Simulation Active Byte 8::Bit 0 The device is in simulation mode and is not
reporting actual information.
Low Signal Quality Byte 5::Bit 0 The Signal Quality is below the defined alert
limit.
Interface Measurement Lost Byte 3::Bit 0 No valid Interface reading. Reasons may be
multiple:
• No valid surface echo peak in the measuring
range.
• Incorrect transmitter configuration.
Capacity Denied Byte 12::Bit 0 The device has failed to require all of the
necessary wireless bandwidth to broadcast at
the configured rate(s).
Message Additional Status

(1) Location of the Alert in the HART command 48 Additional Status field.
Description
Database Memory Warning Byte 0::Bit 2 The device has failed to write to the database
memory at some time in the past. Any data
written during this time may have been lost.
Non-Critical User Data Warning Byte 2::Bit 1 A user written parameter does not match
expected value.
Volume Range Warning Byte 4::Bit 7 The level measurement is outside the
configured volume range.
Button Stuck Byte 1::Bit 5 The button on the Electronics Board is
detected as stuck in the active position.
HiHi Level Alert Byte 5::Bit 4 The level is above the defined limit.
Hi Level Alert Byte 5::Bit 5 The level is above the defined limit.
Lo Level Alert Byte 5::Bit 6 The level is below the defined limit.
LoLo Level Alert Byte 5::Bit 7 The level is below the defined limit.
User Defined Alert Byte 5::Bit 3 The variable has surpassed the user defined
limit.
