DEFAULTS
Select the Learn False Echo menu option. Options are to quit to the
previous menu, or start the learning process.
The transmitter can learn that the present distance measurement is
calculated from an echo off a false target, and the false echo can be ignored.
If there is an echo from yet another false target, repeat the learning process
again. A maximum of four false echoes can be learned.
•
To clear all learned false echoes, see P089 on page F-21.
•
To edit new or existing false echo data, see P081 to P088 on page F-21.
•
For automatic learning, use the Auto Tank Map feature (see below).
Select the Auto Tank Map menu option to view the parameter screen.
Options are to quit to the previous menu, or start the mapping process
The transmitter can be instructed to map up to four echoes from false targets
within an empty tank. The tank needs to be empty so that echoes from all
false targets are exposed.
•
To clear the learned false echoes after using auto tank mapping, see
P089 on page F-21.
•
To edit false echo data, see parameters P081 to P088 on page F-21.
•
For non-automatic learning, use the Learn False Echo menu option.
Select the Simulation menu option to view the parameter screen. Options
are to quit to the previous menu, or select a simulation.
The transmitter simulations automatically cycle the output Primary Value (PV)
between the bottom of the tank and the nearest measurable distance.
Simulation options are:
•
Run up – cycles up, and then down, repeatedly until stopped.
•
Run down – cycles down, and then up, repeatedly until stopped.
•
Run from Zero – as "Run up" except output PV initially starts from 0.
The direction of the cycle is given by the name of the simulation chosen.
A single cycle takes 100 seconds to complete. The Current Output, and relays
(where fitted) respond according to the output PV.
The cycling may be paused by with the pause option, and then re-started by
selecting a simulation.
To stop the cycling, select the normal option.
By selecting this Restart Device menu option, the transmitter re-loads the
user default parameter values, and then performs a restart. The resulting
restart is identical to the normal power-up sequence when first taken out of
the box.
It may, occasionally, be necessary to re-set the transmitter parameters to
factory default values, particularly if the data already changed and held in the
transmitter is in question.
NOTE:
Re-loading factory defaults will overwrite all parameters and all site entered
data will be lost.
