Commissioning; Preparation; Coarse Alignment - Simtronics GD1 MK3 Operating Manual

3. COMMISSIONING

The commissioning of the GD1 consists of four steps:
• Section 3.1 Preparation.
• Section 3.2 Coarse alignment.
• Section 3.3 Fine tuning
• Section 3.4 Function test
3.1.

Preparation

Before commissioning check that the following points are fulfilled:
• Commissioning should be carried out in clear weather in order to allow for correct
transmission settings.
• There is a free line of sight between the transmitter (TX) and receiver (RX).
• Check that optical surfaces on the detector and reflector are clean and dry.
• There should be no H
Power up the GD1 system and let it warm up for 30 minutes before doing the final
alignment in section 3.3.
3.2.

Coarse alignment

The objective for the coarse alignment is to set an initial transmission level. This signal level
is then used as a reference for further tuning, and a minimum signal level must be present
before fine alignment can be performed.
# Description
Clean the lens on the RX and TX and remove the
1
cover from the alignment slot.
Turn on Alignment Laser and insert into the RX
2 alignment slot, and the Laser Target Plate on the
TX side.
Do not stare directly into the Alignment Laser when it is operating. It is
recommended to use the laser safety glasses. In sharp sunlight, the glasses will
also make it easier to see the laser pointer.
