Simulation Mode
This function enables the user to test the settings of the outputs. The Echotel can simulate a static or continuos change of
level, according to the preset simulation parameters.
Set the required simulation by programming P84, P85, P86 and P87.
P84: - - - x Simulation Mode
X
Simulation type
0
No simulation
(FACTORY DEFAULT)
1
The level changes continuously up and down between the level
values set in
P86
and
P87
with a cycle time set in
P85
2
Static level simulation: the level will be the value set in
P86
P87
P86
P85
LEV [m]
t [sec]
The simulation levels must be within the programmed measuring range:
P04
and
P05
.
P85: (sec)
Cycle time for simulation
P86: (m)
Simulated low level value
P87: (m)
Simulated high level value
To start the simulation mode, return to the measurement mode. While the Echotel is in simulation mode the DIST, LEV or
VOL symbol will be blinking.
To quit the simulation mode, set:
P84= 0
.

Access Lock
P99: dcba
Access Lock by Secret Code
The purpose of this feature is to provide protection against accidental (or intentional) re-programming of parameters.
The Secret Code can be a numeric value other than
0000
. Setting a Secret Code will automatically be activated when the
Echotel is returned to the Measurement Mode. If the Secret Code is activated, the parameters can only be viewed, this is
indicated by the a flashing colon “:” between the parameter address and the parameter value.
In order to program the device locked by a secret code, first enter the Secret Code in
P99
. The Secret Code is re-activated
each time the Echotel is returned to Measurement Mode.
To delete the Secret Code, enter the Secret Code in
P99
. After confirming it with
[E]
re-enter the parameter
P99
and enter
0000
.

Error description
Causes and actions to be done
1
Memory error
Contact local agent
No Echo
or
2
Echo loss
No echo received (no reflection)
3
Hardware error
Contact local agent
4
Overflow
Check settings
5
Code referring to sensor error or improper
installation/mounting, level in the dead band
Verify sensor for correct operation and check
for correct mounting according to Users Manual
6
The measurement is at the reliability threshold
(only for free flowing solids level measurement)
Re-aim the sensor or try to find a better location
7
No signal received within the measuring range
specified in P04 and P05.
Review programming, also look for installation
mistake
12
Linearisation table error: L(1) and L(2) are both
zero (no valid data-pairs)
See the Section ”Linearisation”
13
Linearisation table error: there are two same L(i)
data in the table
See the Section “Linearisation”
14
Linearisation table error: the r(i) values are not
monotone increasing
See the Section “Linearisation”
15
Linearisation table error: measured Level is higher
than the last Volume or Flow data-pair
See the Section “Linearisation”
