If the “Check PA voltages, power and temperature” check box is selected, these
parameters will automatically be read out together with the automatic system check.
The “PA gain control” can be used to manually change the overall gain of the power
amplifier by selecting the desired radio button and then pushing the “Submit” button.
This option may only be used while the system is stopped, or the PA is set into
standby mode.
With the PA Configuration radio button the correct PA version needs to be selected.
The displayed PA versions got different internal supply voltages. If this selection is
wrong, the system will send out wrong error messages claiming that one of the internal
voltages is wrong.
With the “PA Error Check” button it may be manually read out, if the PA is in self-
protection mode. If everything is OK the status message will display
the text “OK”. If
the PA is in self-protection mode or if there is no control cable to the PA connected,
the status message will display “error/unconnected”.
Note that if the supply voltages and temperature of the PA displayed in the main
window do all ma
ke sense, and the status displays “error/unconnected”, then the PA
should be in self-protection mode. If all these parameters seem to be wrong, the
control cable is not connected, or the PA is not switched on.
With the “PA Error Reset” button the self-protection circuit of the PA may be manually
reset.
This option may only be used while the system is stopped, or the PA is set into
standby mode.
By selecting the “activate standby mode” check box and then pushing the “Set” button,
the PA will be set into standby mode. To wake up the PA again, de-select the check
box and push “Set” again.
Note that it is possible to change the gain of the PA or reset the self-protection circuit
while the PA is set to standby mode.
Further note that the settings for PA gain an
d standby mode will be saved if the “save”
or “save + close” buttons are pressed. The next time the software is started, or the
FCR reboots, the PA will automatically set to these values. This setting might need
some seconds.
If you finished configuring
the software, click on “save” to save your settings or on
“save and close” to close the setup window. If you want to discard your changes, then
click on “close setup”.
