Test Probe Terminals
The test probe terminals are provided on the EC Motor Control Card to measure the
motor RPM or check for a PWM signal using a multimeter.
Manual or Analog Control Modes:
To measure RPM, set the Address DIP Switches at a value greater than 1. The test
probe jacks will output 0-2000 mVDC to represent motor RPM.
Example: 500 mVDC = 500 RPM
To measure demand signal, change the Address DIP Switches to the value of 0.
NOTE: Changing the address will not interrupt power to the Control Card.
Network Control Mode:
In the MODBUS® network control mode, the test probe terminals will always output
0-2000 mVDC to represent motor RPM.
