Troubleshooting EST Controllers (PWM) - continued
EVO/ECM Series Control Test Procedure
Variable Speed Test The motor should be running to perform this test.
Set the multimeter to read 24Vdc.
1. Touch the black lead to the common (Green) wire on
the 4 pin motor connector.
2. Touch the red lead to the Speed (Red) wire on the 4
pin motor connector.
3. Set the EVO/ECM series controller to full speed.
4. The Dc voltage should be equal to the voltage on the white wire (~22Vdc). The motor
should run at full speed.
5. If the motor does not run at full speed, the cable may be defective.
6. Go to the control connector on the motor.
7. Insert the black meter lead into the connector shell hole
containing the single green wire.
8. Insert the red meter lead into the connector shell hole
containing the Red wire. The DC voltage should equal to the
voltage on the white wire (~22Vdc). If it is not, the control cable
is defective. If the voltage is ~22Vdc and the motor does not
run at full speed, contact the equipment manufacturer for further
instructions.
