3.3 ADJUSTING THE TRIP POINT
Adjust the flow switch trip point as follows (see Figure 2, page 12, for trip potentiometer location):
1.
Establish a flow rate at the desired trip level. (This should be done with flow in the line, not
at zero flow. Select a flow rate below your normal usage. One example would be to use 50%
of your lowest normal flow rate as the set point.)
2.
If the LED is green, adjust "Trip" potentiometer clockwise until the relay de-energizes (LED
turns red). This is the alarm condition.
3.
If LED is red, adjust "Trip" potentiometer slowly counterclockwise just until the relay
energizes (LED turns green).
4.
If the relay cannot be made to drop out over the full range of the "Trip" potentiometer, see
TABLE I.
3.4 USE AS A LEVEL SWITCH (Insertion Probes Only)
The probe switch design can be used to provide one point level switch indication. When the probe tips
are submerged in liquid, the relay is energized and the LED is green. When the liquid level drops below
the probes and they are surrounded by air or vapor, the relay de-energizes and the LED turns red.
