Finishing the Installation
1. Connect a shielded CAT5e cable between the
Communication Port RJ45 connector on the router
(see
Figure 7 and Figure 8
) to the Communication
Port RJ45 connector on the Electronic Controller
(see
Figure 7 and Figure 8
) .
2. Connect a shielded CAT5e cable between the Power
Port RJ45 connector on the router (see
Figure 7 and
Figure 8)
to the Power Port RJ45 connector on the
Electronic Controller (see
Figure 7 and Figure 8).
3. Use nylon cable clamps (included in parts bag) to
secure RJ45 cable between the sensors and the
router, and between the router and the Electronic
Controler. Space cable clamps on 6 in. (152 mm)
centers.
4. Move the Electronic Controller’s power switch (see
Figure 9)
to the ON position.
5. Use the LCD Contrast Adjustment screw (see
Figure 9)
to adjust the LCD contrast as desired:
• Turn the screw clockwise to increase contrast.
• Turn the screw counterclockwise to decrease
contrast.
6. Use the Options Menu to configure the Electronic
Controller for your application. See
Setup and
Adjustments
for specific instructions.
7. After configuring the Electronic Controller, replace
the cover.

screen prompts to complete initial setup.
Initial setup must be completed in order to use
the Options Menu to configure the Electronic
Controller for your application. See Setup and
Adjustments for specific instructions.
5. After configuring the Electronic Controller, replace
the cover.
note: If the LCD screen displays “ERROR! CHECK
CAT5 CABLE AND RESET” please check for a loose
connection, a damaged cable, or an improperly ter-
minated cable.

CAlIBrATIon:
The EFAMS product is designed to introduce the
least amount of pressure drop and corresponding
energy penalty. The EFAMS does not sample 100%
of the air flowing into a fan, but instead, measures an
air flow that will track the air flow through the fan.
For initial setup, the fan must be run at three known
flows to complete initial installation.
Follow on screen prompts. See Balancer Field
Calibration Mode Figure 9.

Firmware Version 8.6
The electronic fan inlet air measurement station must be field calibrated by running the fan at three increasing, known air flow
values, Low, Medium and High, or using air flow measurements provided by a Test & Balance (T&B) contractor. It is recommend-
ed to record damper positions and drive speeds while T&B is on site to facilitate recalibration anytime measurement equipment
must be moved or replaced.
RESET SETTING will not delete or reset field calibration settings.
FIELD CALIBRATION OFF will delete field calibration settings and setup steps must then be repeated to restore calibrated op-
eration. DO NOT TURN OFF FIELD CALIBRATION unless setup is being reinitiated.
ZERO CUTOFF is adjusted after completion of Field Calibration. A non-zero display is normal and expected when the fan is
turned off after completion of field calibration. With the fan off and the dampers closed so that NO air is flowing through the fan,
use the up or down arrow and record the highest reading displayed on any single sensor. Enter a value that is slightly greater
than this amount as the zero cutoff value. OFFSET values when used will always be added to all subsequent readings and
should not be used in place of a zero cutoff value.
Field Calibration Overview:
When power is applied to the installed electronic fan inlet air measurement station and equipment is properly installed and con-
nected INITIAL STARTUP FIELD CALIBRATE is displayed. To complete the setup the fan must be able to run at low, medium
and high air flows. With the fan running at a known Low flow value, the UP and DOWN buttons on the transmitter box will be
used to adjust the display so that the value displayed on the transmitter box matches the actual air flow occurring at that same
time. The ENTER key is used to input that value and will automatically advance the display prompt to the next step. The fan
speed and air flow must then be increased to the medium flow value before the Middle flow values is input. And finally the fan
speed and air flow through the fan inlet must be increased to the highest expected Max flow before the Max Flow Point is en-
tered. Power will then be cycled and the calibrated air flow will be displayed while the fan is running. The ZERO CUTOFF is set
AFTER completion of the Balancer Field Calibration steps.
