To enter programming mode: hold step A for 2 s
To quit programming mode: hold step B
Once in Programming mode, the red LED will start blinking, and the yellow
and green LED s go off.
While in programming mode (with the red LED blinking) every step A will
move the device to the next Menu item. The six different Menu items are
indicated by a combination of the states of the yellow and green LEDs.
About 5 seconds after selecting a Menu item and if there is no step A or B,
then the unit will automatically start to execute the menu item. In this case, the
red LED goes on continuously. In the first four Menu Points learning should be
initiated by step A. Blinking of the green LED indicates measurement during
learning. On getting a valid echo the yellow LED will light up and the relevant
numeric value of the measured distance appears on the output (for instance
with measured distance of 0.4 m the output will be 0.4 mA or 0.4 V!) With
repeated step A a new distance can be learnt and the old one will be
overwritten. Step B will finalise learning and result in return to the Menu item
selection. Another Step B will make the device quit Programming Mode.
Parameters a and k can be programmed using Steps A and B in Menu item
4 and 5
Touch-Magnet programming can be enabled or disabled in Menu item 6 using
step A. Disabling of the Touch-Magnet Programming by the use of the magnet
will be completed after quitting Programming Mode.
During Touch-Magnet Programming the Wire-Contact Programming is
disabled and vice versa.
If the unit is left in Programming Mode for more than 10 seconds, it will quit
automatically. After programming is done connect the PRG wire to the GND.
