Setting Span:
Set the cable to the desired SPAN limit then depress and hold the
button until the STATUS LED begins to ash RED. Release the but-
ton (when the LED is ashing RED, not GREEN) and the ashing will
slow down to about two-second intervals which indicates the SPAN
value is being set into memory. When completed, the STATUS LED
will display solid GREEN.
Setting Zero:
Set the cable to the desired ZERO limit and then depress and hold
the button until the STATUS LED begins to ash GREEN. Release the
button (when the LED is ashing GREEN, not RED) and the ashing
will slow down to about two-second intervals which indicates the
ZERO value is being set into memory. When completed, the STATUS
LED will display solid GREEN. Remove power for 2 seconds then
reconnect.

Reprogramming ZERO and SPAN:
Though ZERO and SPAN points have been preset at the factory,
they can easily be changed to match any desired stroke within
the full stroke limits of the sensor. To reprogram the SR1V to your
own settings, remove the rear cover to gain access to the internal
controller board. Locate the push-button on the circuit board and
follow the instructions below.
Please note that ZERO and SPAN points can be set independently. You can set one without setting the other. This operation must
be performed with the sensor under power. Important: when you are finished, disconnect power for a couple of seconds to permanently set
your new settings.

The SR1V leaves the factory set with a 0...10 VDC full scale
output signal. The signal can be reversed or changed
to either 0...5, -5...+5 or -10...+10 VDC (see illustration) by
simply changing a dipswitch located on the controller
board.
If you wish to simply reverse the output signal or change
it to a dierent voltage range, you may do so without
resetting the “zero” and “span” points.
Remove the rear cover to gain access to the board.
