3-state Alarm
For RGH24D, X, Z, incremental channels forced open circuit for >20 ms when signal too low for reliable operation.
For RGH24W, Y, H, I, O incremental channels forced open circuit for >10 ms when signal too low or speed too
high for reliable operation.

For RGB25D, X, Z alarm asserted for signal amplitude <15%.
5
For RGB25Y, H alarm asserted when: - Signal amplitude >150% - Readhead exceeds specified maximum speed.
Also, outputs are 3-stated at signal amplitude <15%
