1. HL 3002
1.1 General
Sometimes the visibility in the measurement path is poor. The reason for
this might be high dust load, smoke or strong ambient light from the
process (as in a combustion chamber). In this case a stronger light source
must be used in the first alignement step. Siemens Laser Analytics AB
can supply a suitable light source labelled HL 3000. This is a point source
using a 50 W halogen lamp and will produce a very luminous light spot -
normally easy to spot in the alignement procedure.

1.2 The alignement procedure
The sensor is aligned using the sensor alignment kit AK 3002 together
with HL 3000. The aligning procedure is as follows:
Receiver side
1. Start by aligning the transmitter side. This is done by removing the
receiver at the quick connect interface and instead mount HL 3000
which defines the optical axis of the sensor pair. While the receiver is
dismounted - check that the lens is clean on the receiver and that the
purging is working.
Receiver side
HL 3000 generates a considerable amount of heat. Protective gloves should be ised
when it is handled.

Transmitter side
2. Dismount the transmitter and check that the lens is clean on the
transmitter and that the purging is working. Then mount the trans-
mitter and twist-dismount the launcher (fiber cable connector in the
middle), twist-mount the cross hair instead. Align with the four bolts
on the flange, the light dot must be centred in the inner ring of the
cross hair.

Receiver side
4. Mount the receiver back again and twist-mount the cross hair
instead of the detector module. Align with the four bolts on the
flange, the light dot must be centred in the inner ring of the cross
hair.
Receiver side
CD 3002 is now aligned and the holder for the fibre connector and the de-
tector module should be mounted in their places.
Finally, instrument air, or which ever method is used to protect the opti-
cal surfaces, should be connected to the appropriate inlets both at the
transmitter and receiver side of the sensor.
The mechanical stability of the sensor mechanics is sufficient to allow
dismounting (the quick connection) of both the receiver and the trans-
mitter. This means that cleaning of the lenses does not require re-align-
ment of the sensor.
