For measuring range setting, voltage must be applied at the position transmitter.
For output current verification, connect a test device for 0
points (+/ ) (for 2-wire systems, connecting a test device is imperatively required).
Both measuring ranges 0/4
be set.
During setting process, the measuring range (normal or inverse operation) is
assigned to the end positions by push button S1/S2 assignment.
For 2-wire systems, switch off <LED end position signalling> prior to setting the
measuring range.
Setting mode activation clears the settings 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]).
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>.
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.
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.
6. Approach both end positions again to check the setting.
If the measuring range cannot be set:
Refer to <Faults during commissioning>.
If the current values (0/4/20 mA) are incorrect:
Refer to <Current values: adjust>.
If the current value fluctuates (e.g. Between 4.0
Switch off LED end position signalling.
Refer to <LED end position signalling: switch on/off>.
The current values (0/4/20 mA) set in end positions can be adjusted at any time.
Common values are e.g. 0.1 mA (instead of 0 mA) or 4.1 mA (instead 4 mA).
