or serious injury if inspection is neglected or the device is operated with an abnormal condition.
Checklist (daily inspection)
Check column
Inspection item
□
Dangerous parts of the machine cannot be reached without passing through the sensing area of the device.
□
Some part of the operator’s body remains in the sensing area when working with dangerous parts of the machine.
□
The device is installed at a distance that is equal to or greater than the calculated safety distance.
□
No safety guard or protective structure damage.
□
No damaged, defective, or bent wires.
□
All connectors are firmly connected.
□
No dirt or scratches on the light emitting surface.
□
Test rods are not deformed or defective.
□
When no objects are present in the sensing area, the operation indicator (green) of the emitter and the
OSSD indicator (green) of the receiver are lit. The control output (OSSD 1 / 2) is ON. You can check for
effects of external noise in this state. If external noise affects operation, remove the cause and reinspect.
□
When moved at a speed of 1,600mm/sec. or less, it should be possible to detect the test rod
(ø14mm for
SF4D-F
□, ø25mm for
SF4D-H
□, ø45mm for
SF4D-A
□) directly in front of the emitter
(A), midway between the emitter and the receiver (B), and directly in front of the receiver (C) (3
positions). When the test rod is in the sensing area (A) to (C), the OSSD indicator (red) of the re
-
ceiver and the operation indicator (red) of the emitter remain lit.

□
When the machine is in the operating state, dangerous parts operate normally (do not stop) when
no objects are present in the sensing area.
□
When the machine is in the operating state, dangerous parts stop immediately when the test rod
is inserted directly in front of the emitter (A), midway between the emitter and the receiver (B), and
directly in front of the receiver (C) (3 positions).
□
Dangerous parts remain stopped as long as the test rod is present in the sensing area.
□
Dangerous parts stop immediately when the power of the device is turned OFF.
□
Be sure to test operation before using the muting function. Check the condition of the muting indi-
cator (dirt, brightness, etc.).
