Programming relay switch-off point (the level where relay becomes de-energised)
Place the Echotel at a distance to the target corresponding to the required switch-off 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) Keep holding magnet to symbol “ B ” =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
Please note that the smallest switch-differential achievable with magnet programming is 20 mm.
“Error indication” by the current output (Check valid echo as above)
Action LED indication
1) Place magnet to the symbol “ A ” = Transmitter in programming mode
2) Place magnet to the symbol “ B ”
repeatedly
to select the required error indication mode
= Hold last value
= 3.6 mA
= 22 mA
3) Place magnet to the symbol “ A ” = Programming completed
“Damping” (Check valid echo as above)
Action LED indication
1) Place magnet to the symbol “ B ” = Transmitter in programming mode
2) Place magnet to the symbol “ A ”
repeatedly
to select the required damping
= 10 sec
= 30 sec
= 60 sec
3) Place magnet to the symbol “ B ” = Programming completed
Reset (to factory default)
Action LED indication
1) Place magnet to the symbol “ B ” = Programming mode
2) Place magnet to the symbol “ A and =
Reset in progress
3) Hold magnet to the symbol “ A ” = Reset in progress
4) Remove magnet when all LEDs are off = End of programming
Error indications during programming (by LEDs)
Action LED status = error indicated Correction
1) Attempted programming = blinking twice = No Echo Find valid echo
2) Attempted programming = blinking three times = access denied (access code
active)
With use of 375 - 0SAP -100 see Chapter 5.2
(P99)
3) Attempted programming = blinking four times = Echotel not in LEV meas. mode With use of 375 - 0SAP -100 see Chapter 5.2
(P01)
4) Programming of the relay
=
blinking alternately = switch-differential too small
Set switch-differential greater than 20 mm
