2.1.2 The control unit

The control unit is contained in a weatherproof enclosure. It contains power supplies, control circuits for the radiometer
temperature stabilization, interfaces to the radiometer and communication circuitry for a computer to operate the instrument.

2.1.3 Connection cables

Three cables are supplied with the PGS-100.

One is for connection between the radiometer and the control unit.
The second is for the supply of mains AC power to the control unit.
The third is for communication between the control unit and the operating computer.

.

2.1.4 CD-ROM

The CD-ROM disk contains the operating software for the PGS-100 and necessary setup files.

2.1.5 Mounting rings

The radiometer is normally supplied with two mounting rings that are used for fitting it to a Prede sun tracker. These are not
required for fitting to a Kipp & Zonen sun tracker, with the PGS-100 Mounting Kit, and can be discarded.

Note

A computer is not part of the PGS-100 delivery.

2.2 Tools required

The tools required to fit the PGS-100 radiometer to a Kipp & Zonen sun tracker are supplied with the PGS-100 Mounting Kit.

2.3 Location and support base

The location requirements are the same as for any instrument designed to be mounted on an automatic sun tracker for the
measurement of direct solar radiation. The radiometer should have an unobstructed view of the sun throughout the complete
solar arc at all times of the year.

The base support for the sun tracker must be rigid and stable and the alignment must be unaffected by weather and environmental
effects. If this is not possible, the sun tracker must be fitted with an active tracking sun sensor to compensate for movements of
the base support.

The field of view and slope angle of the PGS-100 radiometer input optics require that it must be aligned on the axis of the sun
with a pointing accuracy of 0.2 ° or better.

The ambient operating temperature range of the PGS-100 is from -10 °C to +45 °C. For operation over the range from -30 °C to
+45 °C the Low Temperature Option is required. For operation over the range from -10 °C to +60 °C the High Temperature Option
is required. Please note that both options cannot be fitted at the same time.

2.4 Mounting

It is assumed that the PGS-100 radiometer is to be fitted to a Kipp & Zonen automatic sun tracker using the optional PGS-100
Mounting Kit.

2.4.1 Mounting rings

The radiometer is normally supplied with two mounting rings (shown in 2.1.5) that are used for fitting it to a Prede sun tracker.
These are not required for fitting to a Kipp & Zonen sun tracker, with the PGS-100 Mounting Kit, and can be discarded.

2.4.2 PGS-100 mounting kit

The mounting kit comprises two brackets, clamps, and fixings; to be fitted to a side mounting plate of a Kipp & Zonen sun tracker.
Depending upon the sun tracker configuration, a side mounting plate may also be required.

9. Browse the CD again and copy the folder ‘wavelength file’ into the installation directory.
The default location is c:\Program Files\PGS100_verxxxxxx
10. In Windows™ XP the folder should now look as below:

11. In Windows™ 7 the folder should now look as below:

.

12. Open the ‘wavelength file’ folder and check the name of the wavelength file. It should be a text file with no capital letters,
for example ‘10542a.txt’

Note

It is also recommended to copy the ‘PGS-100 calibration constant’ folder from the CD-ROM to this installation

directory for future reference.

13. Remove the CD-ROM from the drive.
It is recommended to turn off the computer and then turn it on again to ensure that the software installation is complete.
14. Store the software CD-ROM in a safe place in case it is needed to reinstall the software, or use it on another computer, in the future.

4.2 Configuring the software

The operating software executable with the ‘sun’ symbol will now appear in the Start Menu in ‘Programs’. This is
‘PGS100_ver317ENG in the example of 4.1 step 9. For ease of use it is recommended to make a shortcut to this application and
place it on the desktop.
1. Double click on the executable and the program will start.
A message will pop up saying ‘A wavelength file does not exist’ - this is normal because the software is not configured yet.
2. Press’OK’. The screen shown below will appear.
3.

Press the ‘STOP’ button before the count down reaches 0 seconds.

Pressing the ‘START’ button or waiting for the countdown to time out will start measurement according to the configuration
settings (not done yet). Pressing ‘EXIT’ will close the program.
A message will pop up saying ‘Serial port COM1. It cannot open’ - this is normal because the software is not configured yet.

4. Press’OK’. Now the main screen will appear.
