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 make 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 and 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”.
