4.6 Split range setting
To change the range from full range to split range remove the
split range jumper.
This way the positioner can be controlled either by a 4 to 12mA
signal or a 12 to 20mA signal.
The start point can be set at 4 or 12mA with the "ZERO"-
trimmer. The end point (range) can be set at 12 or 20mA with
the "SPAN"-trimmer.
Note:
1. These two adjustments are interrelated, so the zero may
have to be reset after changing the range and vice
versa.
2. To increase the signal turn the trimmer screws clock-
wise (CW). To decrease the signal turn the trimmer
screws counter clockwise (CCW).
