Dear All,

The highlights of the tuesday meeting held on 08/02/05 are as follows.

1)The stability probelm of the power convertors occuring after diode tests are sorted out now. Now it is not

required the reset the power supplies either by manual reset or by software reset before launching power test.

2) The reasons for spurious Slow Power Abort is being investigated and is suspected due to the electromagnetic

non-compliance of the cable connected between the controller and power converter. Plans are being made to introduce a software debounce Filter to eliminate the spurious spikes which lead to the Slow power abort.

3)While entering the reports of probelms related to the Cryo Probelm in the E-log book, it has been requested to

elaborate the nature of probelm in detail after discusscion with the concerned Cryo operator.

4)The alarms arising due to the limits crossing for tminV and Vmin parameters in AQA is ascertained to ageing of the Charge Capacitors.

5) The probelms of powering of CD and EF leads in Cluster-D is found to be due to inter change of leads. The

corrective action is taken up on 08/02.

6) If PLCSE errors occuring due to Cryo interlock conditions like Mag300 and Mag300air occuring during the launching of IAP warm final tests, the equipment support should be called.

Have a good day.

Bye
