If you use an external +24V the following arrangements are possible:
Figure 5. Positive logic with external +24V when CMA is isolated from GND using onboard jumper. The
input is active when the switch is closed
Figure 6. Negative logic with external +24V when CMA is isolated with onboard jumper. The input is active
when the switch is closed (0V is the active signal)
You can make the positive and negative logic arrangements also with the internal +24V. Place the
jumper block in the 'CMA isolated from GND' position (as above) and wire the CMA terminal to the
GND terminal of the AC drive.
