Push button operation:
Select range:
Push the
RANGE
button several times shortly until the LED displays the
desired input range.
Select filter:
Push the
FILTER
button once - the LEDs will flash for approx. 3 seconds and
display the current filter setting. Push the
FILTER
button within the three seconds
several times until the flashing LED displays the desired filter range.
Power On Default function
You can store the actual settings of the module in the internal EE-Prom memory. Once the module restarts,
it comes up automatically with these setting. This is important for stand alone applications and for fail save
reasons. If the function is deactivated the module automatically remembers the last pushbutton selected
range and filter.
