51-638 Echotel Model 338 Two-Wire Ultrasonic Transmitter
NOTE:
P81
is not used by the Model 338 transmitter. Default value is 00.
1.6.10 Simulation Mode
The Simulation Mode enables the user to test the settings
of the outputs. Once configured, the Model 338 is able to
simulate a continuous change of level.
P84
Simulation type
Factory default value for P84 is: 0
P84 is used to select the simulation as described below:
Enter values in P85 – P87 as described below to complete
the simulation mode configuration. Note that the simula-
tion levels must be within the programmed values for
measuring range (P04) and deadzone (P05).
To start the simulation mode, return to the measurement
mode. While in simulation mode the DIST, LEV or VOL
symbol will be blinking. To quit the simulation mode,
reset P84 back to zero.
