Installing the XM-220 Dual Speed Module 35
Sensor Placement for Reverse Rotation
The XM-220 module uses two input signals for reverse rotation detection.
Connect the first sensor to Channel 1. Connect the second sensor to Channel
2. Refer to Connecting a Non-Contact Sensor on page 30 for wiring details.
Position the sensors so that:
• The keyway passes Channel 1 sensor before it passes Channel 2 sensor
as the machine rotates in the forward direction, as illustrated in
Figure 2.25.
Figure 2.25 Position of the Sensor
• The sensors are more than 10 degrees apart and less than 170 degrees
apart in the direction of forward rotation; 90 degrees is optimum. See
Figure 2.26.
