Set Lo Limit Flow Switch Point
Enter Setup Mode (see page 3). Press ON
repeatedly until the display shows “gpm” or “lpm”
in the upper right corner and “LO L” in the center.
See Figure 8. Press

to set the flow rate at
which the Normally Open switch contact will
close. Press ON when desired value is displayed.
To turn off this set point, press and hold
∇
until the
display shows “OFF”.
Setup Mode will continue unless you exit.
Set Hi Limit Flow Switch Point
Enter Setup Mode (see page 3). Press ON
repeatedly until the display shows “gpm” or “lpm”
in the upper right corner and “HI L” in the center.
See Figure 9. Press

Switch Set Points
All switch set points are turned off when shipped from the factory.
The switch actuates when sensed value(s) fall below
low level set point(s) and/or sensed values rise above high level set point(s). The switch returns to normal state when the
process fluid reaches programmed flow and/or temperature conditions. There is a 2 second delay to prevent switch chatter.
Any or all of the switches may be disabled or enabled at any time. An internal programming check prevents conflicting low
and high switch values.
Always set the flow switching points using the same units as normal operating units.
