Alignment though two mirrors
9.
Follow instruction 1-4
10. A second person must adjust the
position of the first mirror to the left
and to the right until the entire length
of the second mirror is reflected in the
first mirror. If difficulties are
experienced in seeing the reflection
on the second mirror in the first mirror
then use a piece of white paper cut to
size and position in front of the second
mirror.
11. If the reflection of the white paper is difficult to see in the first mirror then employ a third
person to hold a flashlight in front of the second mirror with the light beam pointing directly
in line with its mirror housing towards the first mirror. Secure the first mirror.
12. Again follow instructions 1 to 4.
13. The second person must adjust the position of the second mirror to the left and to the right
until the entire length of the transmitter unit is reflected through both the first mirror and the
second mirror. If difficulties are experienced in seeing the reflection of the transmitter unit
through both the first then the second mirrors then use a piece of white paper cut to size
and position in front of the transmitter unit.
14. If the reflection of the white paper is still difficult to see through the first and second mirrors
then employ a third person to hold a flashlight in front of the transmitter unit with the light
beam pointing directly towards the second mirror. Secure the second mirror.
15. Ensure the mirrors are directly aligned thus enabling the infra red beams of the transmitter
to reach the receiver. Alternatively, fabricate mirror mountings to include some form of
adjustment to enable movement both left and right and also forwards and backwards from
the central axis of each mirror.
16. Now turn on the power to the light curtain and check that the green LED beam indicator,
mounted on the receiver unit is ‘on’. If not, it may be necessary to finely adjust each mirror
