Zero flow
Activates switch closure output when flow goes to 0 ft/s or below low flow cutoff.
Empty pipe
Activates switch closure output when an empty pipe condition is detected.
Transmitter faults
Activates switch closure output when a transmitter fault is detected.
Flow limit 1, Flow limit 2
Activates switch closure output when the transmitter measures a flow rate that meets the
conditions established for this alert. There are two independent flow limit alerts that can be
configured as discrete outputs.
Totalizer limit
Activates switch closure output when the transmitter measures a total flow that meets the
conditions established for this alert.
Diagnostic status
Activates switch closure output when the transmitter detects a condition that meets the
configured criteria of this output.
Optional discrete input function (AX option)
Externally powered at 5 - 28VDC, 1.4 - 20mA to activate switch closure to indicate either:
Net total reset
Resets the net totalizer value to zero.
Positive zero return (PZR)
Forces outputs of the transmitter to zero flow.
Security lockout
Security lockout switch on the electronics board can be set to deactivate all LOI and HART-based
communicator functions to protect configuration variables from unwanted or accidental
change.
LOI lockout
The display can be manually locked to prevent unintentional configuration changes. The display
lock can be activated through a HART
®
communication device, or by holding the UP arrow for 3
seconds and then following the on-screen instructions. When the display lock is activated, a lock
