9.6.1. Measuring range: set
For measuring range setting, voltage must be applied at the position transmitter.
For output current verification, connect a test device for 0 – 20 mA to measurement
points (+/–) (for 2-wire systems, connecting a test device is required).
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 as-
signed to the end positions by push button S1/S2 assignment.
●
For 2-wire systems, switch off <LED end position signaling> prior to setting the
measuring range.
●
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 acti-
vated:
➥
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 blinking slowly .
→
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 .
Information: For 2-wire systems read current values at test device.
