  • Page 18: Mounting The Tripod Stand

    3.5 Mounting the tripod stand The tripod comes as a kit that needs to be assembled, all bolts and washers are provided. It is advised to mount the tripod while the RaZON is still in its box. While the RaZON bottom flange is facing up, it is easier to mount the tripod this way.
  • Page 19 M4x10mm flat head srews (3x) Mounting RaZON on the tripod Note From the RaZON bottom flange the E-marking and one tripod leg have to be pointed to the East! The tripod feet have 7 mm mounting holes to fix the RaZON to a firm base.

  • Page 20: Mounting The Pole Mount

    3.6 Mounting the Pole Mount The pole mount can be used to install the RaZON on a small surface like an extension tube or pole. The bottom flange of the pole mount has 4 holes for M10 bolts to secure it to the pole or tube. It is advised to mount all pole mount screws while the RaZON is still in its box.
  • Page 21 Step 4: Add the 3 levelling screws (e) to the top flange of the pole mount. There is thread in the top flange and screwing the adjustment screws in through the flange will raise the RaZON on that side. Enabling the levelling of the RaZON Only a er finishing the levelling and azimuth adjustment the RaZON can be secured fully by tightening the screws (d) from step 3.

  • Page 22: Tracker Orientation

    3.7 Tracker orientation The RaZON should be mounted in such a way that one leg of the tripod is pointing East. The pole mount should be orientated such that the E-marking on the RaZON bottom flange is pointing East. Both mounting devices allow a plus and minus 30 degree play (slit hole) to fine adjust the RaZON a er the mounting is fixed.

  • Page 23: Pyranometer Mounting

    3.8 Pyranometer mounting The PR1 is pre-mounted with 3 M4 bolts to the pyranometer mounting plate on top of the RaZON . If any other SMP pyranometer has to be mounted the standard supplied M5 x 80 bolts have to be used. M4 x 16 mm screw M4 locking ring M4 locking ring (3x)

  • Page 24: Pyrheliometer Mounting

    3.9 Pyrheliometer mounting The PH1 comes pre-fitted on the side of the RaZON . If the RaZON is ordered with a SHP1 it has to be mounted using 2 x 5 mm bolts and washers. For the SHP1 it is important to mount it with the 2 alignment target on top. The PH1 alignment target is on the (outer) side of the pyrheliometer.

  • Page 25: Shading Assembly Mounting

    3.10 Shading assembly mounting The shading assembly needs to be completed with the two sections of the long rod as indicated above. First mount the section with the 2 screws as indicated on the le . Then mount the top section with the shading disc. The standard RaZON with the PR1 is supplied with the short section and small shading disc.

  • Page 26: Levelling

    3.11 Levelling Prior to activating the RaZON , it must be levelled on its mounting surface. To help accomplish this task, the RaZON is equipped with a high accuracy bubble on top of the housing. Adjust the levelling feet on the tripod stand or the tilting bolts in the pole mount to move the bubble into the centre of the level.
