tons
→ press simultaneously for 5 s: Activate setting mode [S1] + [S2]
→ press in setting mode for 3 s: Set 4 mA
→ press in setting mode for 6 s: Set 0 mA
→ press in operation for 3 s: Switch on/off LED end position signalling.
→ touch in end position: Reduce current value by 0.02 mA
[S1]
→ press in setting mode for 3 s: Set 20 mA
→ press in operation for 3 s: Switch on/off LED end position signalling.
→ touch in end position: Increase current value by 0.02 mA

9.7.1. Measuring range: set
For measuring range setting, voltage must be applied at the position transmitter.
Information
●
Both measuring ranges 0/4 – 20 mA and 20 – 0/4 mA (inverse operation) can
be set.
During setting process, the measuring range (normal or inverse operation) is
assigned to the end positions by push button S1/S2 assignment.
●
Setting mode activating clears the setting in both end positions and sets the
output current to a value of 3.5 mA. After activation, both end values (0/4 mA
and 20 mA) need to be reset.
●
In case of inadvertent incorrect adjustment, the settings can always be reset
by renewed activation of the setting mode (simultaneous pressing of [S1] and
[S2]).
Activate setting mode
1. Press both push buttons [S1] and [S2] and hold down for 5 seconds:
➥ By pulsing double flashes, the LED indicates that the setting mode is correctly
activated:
➥ For any other LED flash sequence (single/triple flashing): ➔ Refer to <Faults
during commissioning>.
Set measuring range 2. Operate valve in one of the end positions (OPEN/CLOSED).
3. Set desired output current (0/4 mA or 20 mA):
→
for 4 mA: Hold down push button [S1] for approx. 3 seconds,
until LED is slowly blinking .
→
for 0 mA: Hold down push button [S1] for approx. 6 seconds,
until LED is blinking fast .
→
for 20 mA: Hold down push button [S2] for approx. 3 seconds,
until LED is illuminated .
4. Operate valve into opposite end position.
➥ The value set in end position (0/4 mA or 20 mA) does not change during travel
in setting mode.
5. Perform setting in the second end position following the same steps.
