. Extra conductors can act as antennas, picking
up electrical noise. Failure to observe this caution could result in improper sensor operation.
A and B
channel input
signal wiring
Wiring to these inputs should be shielded cable, with the shield tied to TB2−5
common only. TB2−7 is the single-channel A input signal, and TB2−8 is the channel
B input signal. TB2−8 is Quadrature only. See Figure 7.
