Configuration
Different applications may have different probe positions that indicate a “normal”
condition (vertical vs. tilted). There are two jumpers on the circuit board to control
the behavior of the alarm lights and contacts in regard to probe position. Use the
following Function Mode tables to determine the correct jumper settings for your
application.
