DCS Instructions K. Grogg, M. Weinberg, M. Grothe
Monitoring • Check that monitoring is working • Data is being recorded • Bugs in the code • Check that the system is in a good state • Top level state machine • Histograms for each RMC • Enter information in elog • What was checked and results • Details on any errors, alarms, warnings
Finite state machine • Are the FSM states of unmasked RMCs either standby or ok? • Any known errors should be masked • RMC10 might be off or in error, usually ok • If not masked, take control (click lock icon), and change check mark to X • Does the alarm/alert overview panel report any warnings and faults? • Does the alarm/alert history show any new alarm/alert entries? • Need to take control (lock icon) to see • Be sure you have released control when done!
RMC GUI • Double click on each RMC to get panel • Click “Send Unprivileged Command” • Is information about the crate sent every minute? • If not, note that there is a monitoring problem, contact an expert • Look at histograms (right click on top of histogram to see actual values) • Is the system healthy? • Are the temperatures, power supplies, etc stable? • Look for spikes or slowing rising/falling values • Make sure numbers in histograms match those in the “System Status” • Checks that values are recorded in the database
What to expect • Temperatures should be fairly stable • Look for spikes or slowly rising values • Voltages should be very stable • Supply current should be around 50 • Alarm Status should be zero • Note any changes and when they occurred • Online/Offline should be one • Note any changes and when they occured
In case of problems • Check “Detailed Alarm Status” and “Detailed System Status” • Know where alarms are coming from • Diagnose the problem • Call an expert • Check “Most Recent Fault Record” to see error info • Check time stamp • If rack power is switched off, some information may not be updated • Do not Refresh All! • Do not click POWER ON, POWER OFF, CLEAR ALARM, or Further Expert Action! • Be sure to enter everything you find in the elog
