5.1 Touch-Magnet Programming
The following can be programmed: with the supplied
magnetic calibration tool – screwdriver PN°013-6165-
001:
•Assignment of the 4 mA analogue output to a required
e.g. min. level / max. distance
•Assignment of the 20 mA analogue output to a required
e.g. max. level / min. distance
•Error indication by the current output (Hold, 3.6 mA,
22 mA) see Chapter 6.2.(P12)
•Relay switching different
•Damping (10, 30 and 60 sec)
•Reset to the factory default
Note: Current output can also be assigned in inverted
mode:
4 mA= 100% (Full), 20 mA= 0% (Empty)
Programming is only possible if the Echotel receives
valid echo i.e.“ECHO” LED is lit !
and transmitter is in LEV measuring mode (factory
default).
The accuracy of the setting with this programming method
is limited to ±20 mm. Thus the relay switching difference
between “On” and “OFF” must be greater than 20 mm.
Place magnet to at 0% level:
LED O O O
Hold magnet in place while setting:
LED O O O
Remove magnet when ready:
LED O O O
Place magnet to at 100% level:
LED O O O
Hold magnet in place while setting:
LED O O O
Remove magnet when ready:
LED O O O

For programming: put magnetic screwdriver in accordance with the drawing to place A or B and check the LEDs for their status:
= LED is on, = LED is blinking, = LED is off, = LEDs are blinking alternatively
Make sure that after programming completed all other magnetic influences will be avoided.
Minimum level, 0%, empty tank (assignment to 4 mA,)
Place the Echotel at a distance to the target corresponding to the required maximum distance/minimum level.
Action LED indication
1) Check valid echo = Valid echo received, transmitter
programmable
2) Place magnet to the symbol “A” and = Transmitter in programming mode
3) Hold magnet in place = Distance assigned to 4 mA
4) Remove magnet when all LEDs are
off
= Programming completed
Use level in tank or a fix target e.g. the wall
Maximum level 100%, full tank (assignment to 20 mA)
Place the Echotel in a distance to the target corresponding to the required minimum distance/ maximum level.
Action LED indication
1) Check valid echo = Valid echo received, transmitter
programmable
2) Place magnet to the symbol “B” and = Transmitter in programming mode
3) Hold magnet in place = Distance assigned to 20 mA
4) Remove magnet when all LEDs are
off
= Programming completed
Use level in tank or a fix target e.g. the wall
Programming relay switch-on point (the level where relay becomes energised)
Place the Echotel at a distance to the target corresponding to the required switch-on point. (Do not forget to check valid Echo!)
Action LED indication
1) Place magnet to symbol “A”” =Programming mode
2) Place magnet to symbol “B” and =Programming in progress
3) Hold magnet to symbol “B”=Programming in Progress
4) Place magnet to symbol “A”=Programming in Progress
5) Remove magnet when all LEDs are off =End of Programming
Use level in tank or a fix target, i.e. the wall
