ALIGNEMENT / TESTS |
|
1 |
Switch on the barrier and verify that the LED4 (green) counts 3 times the right number of the connected optical heads (both for TX and RX) |
|
2 |
Put in on the dip 5 on the IMN240TX and verify that the L1 (red) blinks quickly. Switch on the dips 4-5 on the IMN240RX and verify that L1 (red) blinks slowly. |
|
3 |
Select the optic that must be aligned on TX and RX, selecting correctly the first 3 dipswitches on IMN240 Logics |
|
4 |
Move horizontally the optical heads (suggested before TX and then RX) trying to find the maxium value in D.C on the multimeter (it must be inserted ONLY in the IMN240RX test points). |
|
5 |
Move vertically the optical heads trying to find the maxium value in D.C on the multimeter . |
|
6 |
Obtained the maximum value, apply the filters on the RX optic and restart from point 4. |
|
7 |
Obtained the maximum Volts value with the filters (suggested to apply at least until fhe filter number 3) change the optical head and restart from point number 3. |
|
8 |
When ended with the alignments made all needed crossing tests and regulate the time of disqualify intervention and of the beam intervention with the related trimmers on the IMN240RX. After every change store the datas switching on for some secords dip number 6 on the IMN240RX |
|
1 |
Insert the MES051D module in the related IMN230RX connector |
|
2 |
Connect the multimeters probe (Set as Volts D.C) to clamps 1 (-) and 7 (+) of module MES051D |
|
3 |
Put in ON dip7 on the IMN230RX, and verify that there is signal reception. If not put in off again the dip7, otherwise align the microwave with the dip7 switched on. N.B : At the end of the alignment put dip7 in OFF |
|
4 |
Move horizontally the TX and RX parabolas, trying to reach the maximum value possible on the multimeter (max 3.3V) . |
|
5 |
Move vertically the TX and RX parabolas, trying to reach the maximum value possible on the multimeter (max 3.3V) . |
|
6 |
If the value on the multimeter reach 3 ore more Volts, rotate clockwise the AGC trimmer to reduce this value (the trimmer is not linear). Then restart from the point number 4. |
|
7 |
Reached the maximun possible alignment, set through the AGC trimmer the alignment value in a range from 2.5V and 2.7V |
|
8 |
Made the crossing tests and set the values of sensitivity and detection time rotating the trimmers under the MES051D connector, according to the value tables on pdf manuals. Put the dip5 in on for some seconds to store datas on the microwave |
