xxxx
– level value assigned to the 4 mA current output
Manual:
set the level value manually (by using the
/
/
keys) and save it (with
) counted from the maximum
measuring distance (H), which is to be assigned to the 4 mA output current
Automatic
*
:
use the “GET LEVEL” function (
+
) when the medium in the tank is at the level to be assigned to the
4 mA value (“GET LEVEL” function only works if the ECHO LED is on) and save the displayed value as described above (with
).
Default value:
0 m (0%, empty tank)
xxxx
– level value assigned to the 20 mA current output
Manual:
set the level value manually (by using the
/
/
keys) and save it (with
) counted from the maximum
measuring distance (H), which is to be assigned to the 20 mA output current
Automatic
*
:
use the “GET LEVEL” function (
+
) when the medium in the tank is at the level to be assigned to the
20 mA value (“GET LEVEL” function only works if the ECHO LED is on) and save the displayed value as described above
(with
).
Default value:
measuring range = X
M
– X
m
(max. measuring distance – max. measuring distance (dead band))
Error indication by the current output
by using
/
there are three options. According to the selected option, the current output "HOLD” (holds the last
value)“3.6” – gives 3.6 mA value; “22” – gives 22 mA value (for example in case of echo loss).
Default value:
HOLD
Damping time
– select the required damping time (with the
/
key) and save the value as described above.
Default value:
300 s
Relay energized xxxx: level
of the relay's energized state
If the value exceeds this programmed value, the relay will be energized
The step of programming are the same as that of the current output assignment
Relay de-energized xxxx: level
of the relay's de-energized state
If the value drops below this programmed value, the relay will be de-energized
The steps of programming are the same as that of the current output assignment
Note: – the current output can also be programmed for inverted operation: 4 mA= 100% (Full), 20 mA= 0% (Empty)
– sources of possible errors are listed in 5.4.11 - "Error Codes"
For the
Automatic
function, the EchoTREK must be set to (LEV) level measurement mode and the ECHO LED must be on.
GET LEVEL will result in a correct value if the H = xxxx – ‘maximum distance to be measured’ is already set!
