In case that even if the light beam between the emitter and the receiver of the
ST4-A□ is interrupted and the beam interruption indicator (red) on the
emitter/receiver on the ST4-A□ does not light up, or the control output indicator
(green) on the controller does not turn off, see (see "Troubleshooting" on page 79)
and report the symptoms to the maintenance staff in charge.
NOTE
If the indicators show reception of the light beam even though the beam is
interrupted by hand, check whether there is a reflective object or extraneous
light source near the sensor.
