PBG7 Configuration
First, depending on the configuration the processor checks that it can communicate with the
PBG5 four channel trigger module and the PBG7 HV power supply module.
Then each of a total of up to 86 stacks is powered up in turn. Its voltage is measured and
checked to be within acceptable limits. This takes a few seconds, during this period all keys are
ignored.
Finally a summary of the test is displayed
<PBG7 system tested
PBG5 comms pass
PBG7 comms fail
3 stacks faulty
The first line displays the configuration selected. The second and third lines display the status of
the necessary system control links for this confguration to each of the PBG5 four channel
trigger module (PBG5) and PBG7 HV power supply module (PBG7). If a comms fail is
indicated it is necessary to investigate and rectify. Note that modules that are not powered up
should be disconnected from the control link.
