 **POWER INTERRUPTION RECOVERY**
-This process will guide the operator through the steps to recover from a brief ( less than 1 minute ) power interruption.  The goal is to quickly restore critical support systems before they reach an inoperable state.  This process should take less than 3 minutes.

+The source vacuum controls and cooling water pump switches are kept in an "on" configuration by a UPS located on the sputter source vacuum cabinet.  The UPS should keep these controls running for 30-40 minutes.  The pumps themselves will thus restart automatically when the power comes back on, as long as the UPS is still working.
 If a power blink is observed, or the phase alarm activates, immediately follow these steps as soon as the power comes back on:
-)	Re-activate the cooling water loop pumps.  The controls are located at the entry to the source area. (Ground the high voltage cage). Push each start button.  The source cooling water must also be re-activated.  This control is on the side of the cabinet that is against the wall by the sputter source.  You may need to hold the “on” switch for several seconds before the pump will remain on.
+)	Check the cooling water loop pumps.  The controls are located at the entry to the source area. (Ground the high voltage cage). All but the top panel should be showing a green light.  The source cooling water must  be re-activated.  This control is on the side of the cabinet that is against the wall by the sputter source.  You may need to hold the “on” switch for several seconds before the pump will remain on.
