Step 4 During Step 3 above, check that the control output (OSSD 1 / 2) is in OFF state, and
both the OSSD indicator (red) of the receiver and the operation indicator (red) of the
emitter light up as long as the test rod is present within the sensing area.
If the behavior of the control output (OSSD 1 / 2) and the turning ON / OFF of the emit-
ter / receiver indicators do not correspond to the movement of the test rod, refer to
“
Chapter 5 Troubleshooting
,” and report the symptoms to the maintenance in charge.
<Reference>
If the indicators show reception of the light even though the test rod blocks the light, check wheth-
er there is any reflective object or extraneous light source near this device or not.
