3. Install the new motor. See “MECHANICAL INSTALLATION” for mounting information, if needed.

4. Using the diagram below (see Step 4), identify each wire color from the failed motor harness with its terminal designation on the HVAC Circuit Board. Write the corresponding wire color in the diagram below to be used as a worksheet for connection to the new motor.

5. Install the provided terminals on the wires according to the diagram below (see Step 5). The terminals are provided in bags identified by their size (3/16” and 1/4”).

6. Connect the wires to the Evergreen EM motor according to the diagram below (see Step 6).

START-UP AND COMMISSIONING

Rotation Sensing

• The first time the Evergreen® EM motor is powered up and receives a low voltage signal on one of the speed taps, it will perform the rotation sensing process. With this feature, the motor will automatically determine the proper operating direction of the blower wheel. NOTE: Do not bench-test this motor. The first time it is energized it should be mounted in the blower housing. Do not disconnect the power from the HVAC unit until the motor continues to run in one direction for more than a minute.
• During the rotation sensing process, the motor will run in both directions, up to four times if necessary, to determine the proper direction of rotation. If the proper direction cannot be determined after the fourth sequence, the motor will operate in the default direction of Counter Clockwise (CCW) as viewed from the lead end.
• When the motor continues to run in one direction for more than one minute, the rotation sensing process is complete and the feature is locked out. The motor will also noticeably increase speed (up to the speed input that is powered). The motor will now operate in this direction without performing rotation sensing even if the line voltage power is disconnected. If the motor direction of rotation needs to be reversed after the rotation sensing process is complete, see “CHANGING ROTATION”.

Speed Tap Selections
The speed tap VALUES (LOW-HIGH speed) of this motor may not exactly match the speed taps of the original motor. It is highly recommended to operate the HVAC system in all modes of operation. Measure airflow and adjust the speeds to match the system performance guidelines in the HVAC system’s manual or unit rating plate.

NOTE:
Install the system ID label, which is included with the motor kit, on the HVAC system near the existing wiring diagram.

ELECTRICAL CONNECTIONS AND OPERATION OVERVIEW

This motor is designed to be operated with continuous line voltage power. This voltage powers the electronic controls and the mechanical motor. However, the motor takes its ON/OFF commands from the low-voltage inputs listed below.

NOTE:
If the original ECM motor is rated 3/4 or 1 horsepower (HP) and is installed in a 120 VAC application, there should be a power factor correction (PFC) choke wired in series with the line voltage to the motor. This device should be left in the system as connected by the HVAC OEM.

This motor is capable of operating from three different input types.

• There are no ON or OFF delays with any of these input methods.

• The speed taps are built with a hierarchy. If using the 24 VAC or 18 VDC input method, you can energize multiple speed taps at the same time. The motor will always operate at the highest tap number (1 5) as labeled here and on the motor plug. See chart.

• Using a PWM control (sold separately), this motor can be energized and operated from 10%-100% output based on the PWM signal. It can also be controlled from a 0-10 VDC control using our 0-10 VDC harness kit. For more information about these accessories please go to EvergreenEM-motors.com and open the “Genteq® Evergreen Multiproduct Brochure” PDF.

  • PWM specification: The PWM signal must be a DC pulse signal with an amplitude range of 15 to 23 VDC and a
    frequency range of 67 to 93Hz or 127 to 199Hz to be recognized as an acceptable input by the control, 10% guaranteed on and 5% guaranteed off duty cycle.

  • Connect the PWM input to the Evergreen EM motor on terminals (C) and 1.

DIAGNOSTICS

If the motor does not operate:
The Evergreen® EM motor will only operate if it is receiving line voltage AND a low voltage input to one of the speed taps (see diagram above).

1. Measure the voltage between terminals (L) & (N). If proper voltage is not present, solve the issue with the HVAC system controls. If proper voltage is present (voltage matching the rating on the motor), go to the next step.
2. Measure the voltage between terminal (C) and the speed tap that is currently energized. See chart above.
   • If the correct voltage is not present, solve the issue with the HVAC system controls.
   • If the correct voltage is present and the motor does not operate, the motor has failed. Before replacing the motor please call our tech support if possible to confirm your diagnosis.

If the airflow needs to be adjusted:
Change the speed tap selection up or down for more or less airflow. If the highest speed is selected and there are still airflow issues:

• Measure the Total External Static Pressure (TESP). If it is higher than the HVAC unit manufacturer’s guidelines, correct the airside issue.
• If the motor is operating in the wrong direction, there will be low airflow on all speed taps and very low amperage. See below for instructions to change the rotation.
• If these issues have been corrected or ruled out and there is still insufficient airflow, please call our tech support.

CHANGING ROTATION

If the motor has been operating in one direction for more than one minute and is not operating in the correct direction continue below. If the motor has not been operating for more than a minute, energize the motor and wait for it to complete the rotation sensing process described. If the motor is operating in the wrong direction of rotation after the rotation sensing process is complete continue below.

Change rotation with the reversing harness
The Evergreen rotation reversing harness is available wherever Evergreen products are sold, catalog # 5K016. The installation instructions are included with the part.

Change rotation with the onboard feature.

1. Disconnect the line voltage power to the HVAC system. WARNING! Using a voltmeter, confirm the power is disconnected.
2. Remove the 24VAC inputs from speed taps numbered 1-5.
3. Create a jumper wire harness that connects speed taps 1, 3, and 5 only to a continuous 24VAC power supply. Example: the thermostat R terminal.
4. NOTE: Do not disconnect the wires from terminals C, L, G, and N. See diagram below.
5. Restore the line voltage power to the HVAC system.
6. Line voltage power must remain on for a minimum of 5 minutes but not over 6 minutes. Use a watch to confirm time.
7. NOTE: The motor may or may not operate during this timeframe.
8. Disconnect the line voltage power to the HVAC system. WARNING! Using a voltmeter, confirm the power is disconnected.
   • The line voltage power must remain disconnected for a minimum of 1 minute. Use a watch to confirm time. During this time remove the jumper from terminals 1, 3, and 5 and reinstall the OEM speed tap connections.
9. Restore the line voltage power to the HVAC system. Provide any demand call to confirm that the motor has now changed direction.

If this process fails to reverse the motor’s direction, repeat the above process. If this process fails to change the direction of rotation, contact Tech Support at 866-503-8566.

MECHANICAL INSTALLATION

The Evergreen® EM motor is built with a NEMA®* 48 (5.6” diameter) frame for installation in a belly band mount. If the failed motor is the same frame size and the motor mount is a belly band mount, it can be reused to mount the Evergreen EM motor.

• If the existing motor mount has 4 welded legs, the Evergreen belly band motor mount stock # 5K002 will likely match the bolt-hole confiduration.
• The belly band should be located on the motor between the motor vents and the dimples that identify the end of the stator stack. Do not block the vents or allow the motor mount to come in contact with the electrical connection block. The 1 HP motor is built with vents on both ends of the stator stack. The motor mount should be located between the vents on the 1 HP model.
• Orient the motor in the mount so that the electrical connections are facing down or at least between the 4 and 8 o’clock position when installed in the HVAC system. When the wires are connected to the motor try to form a drip loop near the motor. This will help prevent moisture from running into the electrical connections.
• NOTE: Center the blower wheel in the blower housing before tightening the hub locking bolt. Tighten the hub locking bolt on the flat the area of the motor shaft.
  • NEMA is believed to be the trademark and/or trade name of the National Electrical Manufacturers Association and is not owned or controlled by Regal Beloit Corporation.
