*There are three (3) RS485 Protocols:
S-Protocol is a RS485 communication based on HART
®
command set.
L-Protocol is a RS485 communication compatible with legacy Unit
®
and Celerity
®
devices.
A-Protocol is a RS485 communication compatible with Aera
®
mass flow devices.
**The Alarm Output is an open collector or "contact type" that is CLOSED (on) whenever an alarm is active. The Alarm Output may be set to indicate any one of various alarm
conditions.
*** The Valve Override Signal (VOR) is implemented as an analog input which measures the voltage at the input and controls the valve based upon the measured reading as shown in
this section.
