Rosemount 3100 Series
P073 to P075
(Relay 2 Setting-up)
P073 to P075 Description
P073 RL2 Mode
P074 RL2 PV On Point
P075 RL2 PV Off Point
On The Rosemount 3102, relay RL2 is a SPST (Single Pole, Single Throw)
type. In the default mode of “Fault”, the relay de-energizes during Lost Echo
or System Fault conditions. This relay de-energizes if the power fails.
The mode of RL2 may be changed to control mode by entering a non-zero On
and Off Point value. In control mode, RL2 ceases to be a fault relay.
All relay set-point values must be entered in the units chosen for the PV.
P081 to P088
(False Echo Data)
P081 to P088 Description
P081 False Echo D1, and P082 False Echo S1
P083 False Echo D1, and P084 False Echo S1
P085 False Echo D1, and P086 False Echo S1
P087 False Echo D1, and P088 False Echo S1
These parameters are the four false echo data records, each storing a false
echo as Distance-to-surface (e.g. 1.7 m) and Echo Size (e.g. 44%).
The transmitter will ignore these echoes from false targets.

P089
(Clear False Echoes)
P089 Description
This is to clear a specified False Echo record, or all False Echo records.
Options are False Echo 1, False Echo 2, False Echo 3,
False Echo 4, or All.
P970 (TX Material) P970 Description
This read-only parameter describes the material of the transmitter.
