Kipp&Zonen 2AP Sun Tracker - Manual (Page 66)

INSTALLATION AND SETUP
65
If the 2AP does not work properly due to corrupt configuration values in the 2AP you can reload the
2AP’s default configuration (e.g. by means of the backup .cfg file) by performing a Cold Start.
Before the .cfg file can be used the .cfg extension needs to be changed to .ini manually. A Cold
Start deletes the configuration file from the 2AP. If the command to recover is given by Win2AP, the
parameters saved in the *.ini file you selected are sent from the PC to the 2AP. After the Cold Start
the 2AP time will need to be reset.
The Cold Start Procedure is as follows:
•
Connect the PC to the 2AP, select “Troubleshooting” in the Win2AP Main Menu.
• Go to page 3.
• Turn off the 2AP power supply.
• Remove the set screw in the Azimuth shaft of the 2AP with the hex key (2.5 mm), see figure
4.42.
• To erase the current 2AP configuration values, push the Cold Start microswitch in the screw
hole for 30 seconds (with the same hex key).
• Replace the set screw.
• Re-power the 2AP again.
• Press the “Recover” button to reload the 2AP configuration. Choose the *.ini file to load the
configuration from. If you suspect that the 2AP configuration was invalid, choose the latest
back up of the *.cfg file.
• After a Cold Start the 2AP time needs to be reset, go to either the Run Suntracker or Run
Positioner monitor window and select “Set Time” in the 2AP pull down menu.
• Press the “Get 2AP Time” button. The difference in time between the PC and 2AP is shown
in the textbox.
• Press the “Set 2AP Time” button to set the 2AP clock to match the PC time.
