    keyword=tech/ Left Dipole

    Called in for no responce on lt dipole. Users atempted to fix by reboot IOC but did not fix.

    Found no faults and no responce to controls no current showing on PS or computer.

    We have seen this before so I power cycled allen bradley. There was a clunk at the dynapower but no fault lights. At the computer there was a fast dump indication though no current showed prior to AB power cycle.Still no responce at computer and fast dump will not clear.

    Power cycled Allen Bradley again with no change at PS or computer

    Power cycled Allen Bradley again with no change at PS or computer

    Power cycled Dynapower at PS and disconnect with wait of 30 sec. PS showed ZFCT fault and PS fault but computer showed nothing. Hit reset button on GUI and attempted to start power supply without reseting AB or PS localy.

    All faults cleared on PS and magnet operated normaly.

    Even I get lucky sometimes
