ECMSC Speed Controller

VDC Equations



Example: 24”x48”, FC Wheel, 115V @ 450cfm

VDC = (CFM + 201)/250

VDC = (450+201)/250

VDC = 2.60V

The potentiometer (POT/DIAL) would need to be turned up until the voltage measured 2.60 at the Measurement Tabs

NOTE: The calculated VDC value is intended as a starting point; actual VDC value may differ slightly depending on field variables.

NOTE: ECM Speed Controllers have 2 modes: manual adjust and BAS (Building Automation System). Standard manual control outputs are shown below:

Measurement Tab Voltage Motor Control

0 - 1 VDC Off

1 - 4.5 VDC 0-100%

4.5 - 5 VDC 100%

The speed controller will automatically ignore the potentiometer (POT/DIAL)/DIAL when a BAS signal is detected (BAS Input Signal >1). VDC equations are for potentiometer (POT/DIAL) manual adjustment only (0-1 BAS input signal). The VDC equations are based on a 1-5 Volt scale. The BAS input voltage is a 2-10 VDC scale, and therefore VDC calculated for a given CFM using the equation must be doubled to achieve that CFM using the BAS input.

BAS Voltage Response Notes

0 - 1 VDC Local control mode using push buttons Local setpoint can be adjusted from 0 - 100% using push buttons

1 - 2 VDC Motor Off Recommended sending a 1.5 VDC signal to command motor off

2 - 9 VDC Modulating Control 2 - 9 VDC modulates motor from 0 - 100%

9 - 10 VDC Maximum Speed Motor is running at maximum speed (100%)

STEP 14B: If using potentiometer/manual adjustment, rotate the potentiometer (POT/DIAL) dial on the outside of the box with a screwdriver until the test point voltage is achieved.

EXAMPLE: If using a BAS signal, to calculate appropriate starting voltage, first calculate the VDC (as shown in above example)

VDC = 2.60 V

Then double this value

BAS Input Voltage = VDC*2

BAS Input Voltage = 2.60*2

BAS Input Voltage = 5.20



STEP 15B: Wait a few seconds for the ECM motor to adjust its speed and then verify fan airflow with measurements at the unit face using a flow hood. Adjust the POT/DIAL, or BAS input signal to reach desired airflow as required.

NOTE: If unit is ducted, please refer to Technical Note: Balancing Ducted Units on page 44 of this manual.

STEP 16C: If manually adjusting at the speed controller ensure controller is in Local Setpoint mode (L.SEt). To change modes, press the up and down arrows simultaneously until you reach L.SEt.

STEP 17C: Enter the Local Setpoint value (L. Set) you have found from the chart by using the up/down buttons.

NOTE: The L.Set calculated above is a starting point; actual value may differ slightly depending on field variables.

NOTE: The BAS signal will override the local setpoint using a remote 0 – 10 VDC signal. If the BAS signal drops below 1 VDC local control (via the up/down buttons) is restored.

The ECMDX speed controller can be controlled using multiple strategies; these are outlined in the chart below.

BAS Voltage Response Notes

0 - 1 VDC Local control mode using push buttons Local setpoint can be adjusted from 0 - 100% using push buttons

1 - 2 VDC Motor Off Recommended sending a 1.5 VDC signal to command motor off

2 - 9 VDC Modulating Control 2 - 9 VDC modulates motor from 0 - 100%

9 - 10 VDC Maximum Speed Motor is running at maximum speed (100%)

The VDC equations are based on a 1-5 Volt scale. The BAS input voltage is a 2-10 VDC scale, and therefore VDC calculated for a given CFM using the equations (refer to ECM speed controller on page 10) must be doubled to achieve that CFM using the BAS input.

STEP 18C: Wait a few seconds for the ECM motor to adjust its speed and then verify fan airflow with measurements at the supply outlets using a flow hood. Adjust voltage to reach desired airflow as required.

Technical Note: Design with VAV/Constant Flow Boxes and Ducted ApplicationsIn applications where the fan filter unit will be ducted with upstream VAV, constant flow boxes, valves, or other airflow devices that may have varying airflows, or modes, caution must be taken with balancing and proper selection of fan filter unit.

A constant flow program is not recommended for this type of application. In systems where two controllers are trying to compensate to adjust to a constant airflow, the system will be unable to stabilize. This results in constant adjustment of both controllers until the FFU-HE motor shuts off. The ECM with constant torque motor program or PSC motor is suggested for this type of application.

The FFU-HE is designed to overcome the pressure drop of the filter only. The motor is not intended to pull air down supply ductwork, nor to experience a positive static pressure at the inlet forcing air through the fan. These scenarios will cause starving, or overfeeding of the fan which can damage the fan motor. Fan filter units should be installed in a system where the inlet static will be 0.0” w.g., or slightly negative.

In ducted applications, it is critical that primary air be balanced prior to installing the FFU-HE. The primary air controls should be locked in position post balancing, and the FFU-HE is installed and running. Similarly, the FFU-HE should be bench-set by using a flow hood and adjusting the speed controller, as required, to the same balanced, primary airflow rate before the FFU-HE is mated with the duct. Alternatively, the Balancing Ducted Units Technical Note can also be followed on page 44 of this manual.

To prevent a high static pressure build up at the FFU-HE during start up, the FFU-HE’s should be energized prior to the system. This helps to prevent the possibility of backwards rotations of the blower wheel, which will eventually lead to the motor shutting off.

Excessive negative static air pressure at the inlet is also not an intended use for fan filter units. Negative static at the inlet will cause the motor to be overworked and will lead to decreased motor life. Additionally, inconsistent motor running modes may result, depending on the magnitude of the negative pressure. Positive static inlet pressure will eventually lead to ECM motors shutting off entirely, and PSC motors running inconsistently. The discharge static pressure of the VAV, constant flow boxes, valves, other airflow devices, or balancing damper feeding the FFU-HE should be as close to 0.0” w.g. as possible.

For any additional information, or troubleshooting assistance on systems and design with fan filter units used in sequence with a variable upstream air source, contact Price Industries Fan Filter help at [email protected], or dial (204) 654-5613 option 5.



Technical Note: Balancing Ducted UnitsSTEP 1: Set FFU on benchtop and balance to desired flow using appropriate speed controller set up (Pages X-X).

STEP 2: Confirm airflow using flow hood and adjust speed controller as required.

STEP 3: Lock primary air control

STEP 4: Install FFU into ceiling grid

STEP 5: Turn FFU’s on – ensuring all FFUs on the same system are turned on at the same time.

STEP 5: Unlock primary air control

STEP 6: Measure discharge static pressure at VAV discharge or FFU inlet.

STEP 7: If measured pressure is greater than 0.0” w.g., turn up the FFU in small increments while monitoring the measured pressure. Increment until pressure approaches 0.0” w.g. Similarly, if measured pressure is negative, turn down the FFU in small increments, monitoring the measured pressure until it approaches 0.0” w.g.

NOTE: A slightly negative static pressure is also acceptable.

NOTE: Not recommended for FFU-HE units with ECM units with constant airflow program.

If removing the FFU-HE from the duct is not possible, follow the below instructions for balancing:

STEP 1: Install an air pressure measurement device (i.e. Pitot tube) in the inlet of the FFU-HE.

STEP 2: Power up FFU-HE and set the speed controller to approximately 75% of maximum set point.

STEP 3: Power upstream airflow control device, and set airflow to the FFU-HE to 25% less than design flow.

STEP 4: Read the inlet pressure.

STEP 5: Measure airflow using flow hood

STEP 6: Using the table below, adjust FFU-HE controller, or upstream airflow device as required

FFU Airflow FFU Inlet Static Action

Above Set point Above 0'' W.G. Lower airflow on airflow control device

Above Set point Below 0'' W.G. Lower FFU control setting

Above Set point 0'' W.G. Lower Both FFU and airflow control device

Below Set point 0'' W.G. Raise Both FFU and airflow control device

Below Set point Below 0'' W.G. Raise airflow on airflow control device

Below Set point Above 0'' W.G. Raise FFU control setting

STEP 7: Repeat steps 4-6 unit design airflow is achieved and inlet pressure is neutral (0.0” w.g.).



Troubleshooting Tips:• If FFU is turned to 75% and it shut offs after a short time, follow the below steps:

1. Power cycle the FFU-HE.

2. Measure inlet static while the FFU-HE is running.

3. If the inlet static is positive, reduce your airflow device airflow an additional 25%.

4. Return to Step 4, above and finish balancing unit.

• If the unit shuts off still at this 50% setpoint, follow the below steps:

1. Power cycle the FFU-HE

2. Measure inlet static while the FFU-HE is running

3. If the inlet static is positive, reduce your airflow device airflow 25% more.

4. Return to Step 4, above and finish balancing unit.
