Maintenance

Chapter 4 Maintenance

If an error is found, refer to “

Chapter 5 Troubleshooting

” and contact a professional engineer for the details.

Copy inspection sheets, fill the check columns and file them.

4-1 Daily Inspection

Check the following items before start-up and confirm that there is no error. If this

device is operated in a failed condition without inspection, there may be a risk of

death or severe injury.

Inspection items (Daily inspection)

Check

column

Inspection items

□

There shall be no scratch, bend or breaking of wires.

□

Connectors shall be securely connected.

□

When the test input terminal T1-T2 is open, make sure that control outputs 1 / 2 (OSSD 1 / 2)

are OFF. At this time, effect of external noise can be inspected. If there is effect of external noise,

eliminate the cause and perform re-inspection.

4-2 Periodic Inspection (Every Six Months)

Check the following items every 6 months and confirm that there is no error. If this

device is operated in a failed condition without inspection, there may be a risk of

death or severe injury.

Periodic Inspection (Every Six Months)

Check

column

Inspection items

□

The machine shall be designed not to prevent safety mechanism such as stop or emergency stop.

□

Modification or change of the machine control system that disturbs the safety mechanism shall not

be performed.

□

Output from this device shall be correctly detected.

□

Wiring from this device shall be correctly performed.

□

The number of operation cycle (time) for a part that has a service life (relay, etc) shall be less than

the rated operation cycles (time).

□

Screws and connectors related to this device shall not be loose.

□

There shall be no additional object that generates disturbing light or reflecting light near the sensor.

4-3 Inspection after Maintenance

For the following cases, perform inspection for all items of “

4-1 Daily Inspection

” and

“

4-2 Periodic Inspection (Every Six Months)

.”

1) When this device or sensor part is replaced

2) When an error is felt on operating condition of this device or sensor

3) When the location or installation environment of this device is changed

4) When wires or routing method of wires are changed

5) When FSD (Final Switching Device) parts are changed

6) When FSD (Final Switching Device) settings are change
