Solids Flow Detect Model FD-2000
Controls and Indicators
All user controls and indicators are visible by removing the enclosure cover. Refer to Figure 5 for
location of the controls and indicators.
Following is a list of controls and indicators available:
FLOW Indicator –
This is to assist in adjusting the sensitivity by indicating the margin between
the no-flow and flow conditions. It consists of five multi-colored LEDs, with a red one in the
center representing the trip point between flow and no-flow. Indication to the left is no-flow
and to the right is flow.
OUT Indicator –
This is a yellow LED and will indicate the Flow or No Flow output condition,
which corresponds directly with the OUT relay and 4-20mA output current. When the OUT
indicator is off, the OUT relay is de-energized and the current output is at 4mA. When the
OUT indicator is on, the OUT relay is energized and the current output is at 20mA.
FAULT Indicator –
This is a red LED and will indicate if the OUT condition is not guaranteed
to be valid; such as when the unit is operating near or outside its rated temperature range or
when the internal Doppler sensing element is faulty. This indicator corresponds directly with
