MAINTENANCE
<Reference>
If you notice an abnormal condition, refer “
our web site:
https://panasonic.net/id/pidsx/global
”.
If you are unsure what action to take, contact our office.
Make a copy of the checklist, enter a checkmark after checking each item, and retain the list.
●
Daily inspection
WARNING
Before starting work, inspect the items below and verify that there are no abnormalities. Risk of death
or serious injury if inspection is neglected or the device is operated with an abnormal condition.
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
□(
-01
), ø25mm for
SF4D-H
□(
-01
),, ø45mm for
SF4D-A
□(
-01
),] directly in front of the emit-
ter, midway between the emitter and the receiver, and directly in front of the receiver (3 positions).
When the test rod is in the sensing area, the OSSD indicator (red) of the receiver and the operation in-
dicator (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, midway between the emitter and the receiver, and directly in front of the receiver (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 indicator
(dirt, brightness, etc.).
●
Periodic inspection (every six months)
WARNING
Be sure to inspect the following items every six months and verify that there are no abnormalities. Risk
of death or serious injury if inspection is neglected or the device is operated with an abnormal condition.
Check column
Inspection item
□
The structure of the machine does not obstruct any safety mechanisms for stopping operation.
□
No modification has been made in the machine control system that obstructs the safety mechanisms.
□
Output from the device is correctly detected.
□
Wiring from the device is correct.
□
The response time of the overall system is equal to or less than the calculated value.
□
The current number of operation cycles (time) of parts with a limited service life is less than the num-
ber of service life cycles (time).
□
No screws or connectors related to the device are loose.
□
No objects that scatter or reflect light have been added near the device.
●
Inspection after maintenance
1.
When any parts of the device are replaced.
2.
When an abnormal condition is noticed during operation.
3.
After aligning the beam axes of the emitter and receiver.
4.
When the installation site or environment of the device is changed.
5.
When the wiring method or wiring layout is changed.
6.
When a safety relay unit or external device (forcible guide relay or magnetic con-
tactor) part has been replaced.
7.
When safety controller or safety PLC settings are changed.
When using as a safety device for a press machine in Japan
(Applicable model: SF4D-□-01)
When using as a safety device for a press machine in Japan, press machine work
supervisors and personnel in charge of the matters described in No. 1, No. 2, and
No. 4 of Article 134 of the Occupational Safety and Health Act are required to per-
form inspection prior to the start of work and perform periodic inspection.
Press machine work supervisors, etc. must inspect the items below prior to the
start of work and record/retain the results.

Notes: 1) Because the control output (OSSD 1 / 2) must be OFF for at least 80ms, the ON response will be delayed
more than 50ms when the light blocked time is less than 30ms.
2) When optical synchronization is selected, if the beam axes of both the top end and bottom end are blocked,
the ON response speed decreases by as much as 1 sec.
