  1. BCS Top-Off Interlock Automated Testing Plan SSRL BCS Top-Off Review February 15th, 2008

  2. Automated Testing Plan(Overview) • The SPEAR control system has access to a large number of “test points” and status information of the BCS Top-Off Interlock. • All outputs of the summary chassis • Output status of all threshold detectors • The SPEAR control system controls all power supplies and monitors the SPEAR beam current. SSRL BCS Top-Off Review February 15th, 2008

  3. Automated Testing Plan(Power Supply Verification) • The control system • Gets updated readbacks somewhat faster than every second • Ramps the individual supplies with a slope that allows measurement of voltage and current within the required precision • Verifies the measured trip currents and voltages against correct trip values • Verifies the status changes on the summary chassis for the individual power supply thresholds • Maintains the correct trip levels in a database SSRL BCS Top-Off Review February 15th, 2008

  4. Automated Testing Plan(Power Supply Verification) current/voltage upper thresholds nominal value lower thresholds chain A (V): F T F chain B (V): F T F chain A (I): F T F T F chain B (I): F T F T F 0 0 time SSRL BCS Top-Off Review February 15th, 2008

  5. Automated Testing Plan(TOSCI Verification) • The control system • Monitors the beam current during every fill from zero • Verifies the TOSCI chassis by comparing the measured DCCT beam current at the TOSCI state change times with the correct current value • maintains the correct trip levels in a database SSRL BCS Top-Off Review February 15th, 2008

  6. Automated Testing Plan(TOSCI Verification) DCCT beam current threshold chain A (DCCT): F T chain B (BPM): F T 0 0 time SSRL BCS Top-Off Review February 15th, 2008

  7. Automated Testing Plan(Reporting and Actions) • The control system will generate a printed report for each verification (e-mails can also be sent) • In case of detected anomalies (non-functioning signal chains or threshold deviations), the control system will apply a fault to the summary chassis and will NOT allow a summary chassis reset.

  8. Non BCS Interlock(Control System Components) BTS Stoppers and Chopper Power Supply Power Supply Controller (EtherPSC) BCS High Speed Fan In Server 1 (Interlock) Server 2 (Watchdog) IOC Software Interlock Database Interlock Limits (password protected) Modification Log SSRL BCS Top-Off Review February 15th, 2008

  9. Non BCS Interlock(Management) • The limits can be modified by authenticated and authorized personal via a web interface. • Any limit modification will be logged in the database (name, timestamp, value). • The log is accessible via a web interface. SSRL BCS Top-Off Review February 15th, 2008
