1. Mount the 1/2-in. NPT adapter in a horizontal or
vertical section of pipe. The maximum distance
from the control panel must not exceed 29.5 ft (9 m)
(see item labeled "1" in the preceding figure). Allow
at least five pipe diameters straight run of pipe
upstream of the sensor location, and three pipe
diameters straight run of pipe downstream of the
sensor location.
N N o o t t e e s s : :
•
In Agility ™ chillers, the ifm efector ® flow
detection controller and sensor is
mounted in the waterbox nozzle, as
shown in the preceding figure.
•
If the ifm efector ® flow detection
controller and sensor is mounted in an
alternate location on a horizontal pipe,
mounting the sensor in the side of the
pipe is preferred; in the case of a vertical
pipe, mounting the sensor in a place
where the water flows upwards is
preferred.

2. Insert the flow sensor probe (see item labeled "2"
in the preceding figure) through the 1/2-in. NPT
adapter so that 3 to 3.5 in. (7.6 to 8.9 cm) of the
probe's length extends into the pipe. Tighten the 1/
2-in. NPT adapter as needed to prevent leakage and
keep the probe from backing out under pressure.

N N o o t t e e : : When installed, the tip of the ifm efector ®
sensor probe must be at least 1 in. (2.54 cm)
away from any pipe wall. Do NOT insert more
than 3.5 in. (8.9 cm) of the probe length into
the pipe.
3. Install the Micro DC Cable by inserting it through
the wire openings on the back side of the control
panel (see item labeled "3" in the preceding figure).
Install the supplied Micro DC Cable (29.5 ft [9 m] in
length) to the Flow Probe and hand-tighten the
connector nut.
4. Plug the other end of the Micro DC Cable into the
Flow Control Monitor with the Combicon connector
(see item labeled "4" in the preceding figure). Refer
to the following figure for cable wiring.

5. Apply power to the chiller control panel to verify the
Flow Control Monitor has power and the Low Volt
Broken Wire Relay light is NOT lit.
6. Remove all air from the piping circuit prior to
adjusting the low water flow setpoint.
7. Reduce the water flow to the minimum allowable
flow and adjust the Flow setting on the Flow
Control Monitor (see item labeled "7" in the
following figure). Adjusting the "Flow"
potentiometer clockwise (+) reduces the flow
setting cutout and adjusting counterclockwise (-)
increases the flow setting cutout.
N N o o t t e e : : The "Temp" potentiometer on the ifm
efector ® control module has no effect in
Trane application. It is NOT necessary to
make adjustments to the "Temp"
potentiometer.
8. After the cutout setting is adjusted, the cutout
setpoint will be indicated with a yellow light on the
Flow Control Monitor LED bar graph display. When
the water flows are higher than the cutout, a green
light will indicate proper flow status. If the flows fall
below the cutout setpoint, a red light will indicate
low/no flow status.
