Preparation for operation

Operation check

Preparation

Perform the following check or work before turning ON the power.

Releasing optical unit lock screw

The optical unit in the detector is fixed by optical unit lock screws, to avoid possible vibration
or shock during transportation or mounting work.
When the detector mounting and wiring work are completed, remove the optical unit lock
screws (3 pcs), and replace them with the truss head screws with O-rings (3 pcs) supplied as
accessory. (Refer to Fig. 20.) 

Note

If the instrument is in operation with the lock screws fixed after the detector mounting, a correct
detection may not be possible. Further continuous use in this condition may damage the inside of
detector.
Before removing the detector, first confirm that the power is turned OFF, and replace the truss head
screws (three locations) with the lock screws retained. If transported with the truss head screws, it
may damage the detector due to shock during transportation.

Fig. 20  Release of optical unit lock screw

1.

Remove three optical unit lock screws.

2.

Replace the truss head screws with O-rings (M5).

Preparation

Attached round tray (for test)

Sample oil (olive oil, diesel fuel, kerosene, and others)

Tap water

Truss head screws with O-rings (M5)

Optical unit lock screws
