3. To set a current supply
■
of 3.6 mA, during the dwell time (10 seconds) in error mode, press the “4 mA” button
briefly (0.1 ... 2 seconds).
■
of 21.5 mA, during the dwell time (10 seconds) in error mode, press the “20 mA”
button
briefly (0.1 ... 2 seconds).
The adjustment of the measuring range is only saved when the level
transmitter automatically changes from adjustment mode to measuring mode
and the LED goes out. The adjustment is retained even if the level transmitter
is subsequently disconnected from the power supply.
4. Screw the probe head cover
back down.
If the level transmitter detects, during operation, that a correct output of the level is not
possible due to a too low supply voltage, it switches to error mode and sets the current
supply to 3.6 mA (independent of the error current settings made).
6. Safety-related characteristic values
For the connection of the level transmitter to a certified intrinsically safe circuit, the
following maximum values apply:
