| Reseting an BLEPS Trip (worstation interface) |
| |
| Steps: |
- Bring up main beamline MEDM screen.
- Look at BLEPS MEDM screen for station which is in fault condition and determine which component
caused the fault.
- Reset fault.
- If fault was a vacuum fault, open vacuum gate valves after resetting it in step above.
|
| 1. Main beamline status MEDM screen: |
| A trip of the BLEPS system can be reset from same computer
that you are using for data aquistion. To do this, either bring up the main beamline status shown below
or go to the workspace labeled "EPS/PSS" on the center screen. An BLEPS fault would show up
as a red indicator on any of the BLEPS status lights on the bottom of the screen. If the BLEPS horn
is sounding you can press the "Silence Horn" button to turn this off. You can attempt to reset
the BLEPS system at this point by pressing the "Reset EPS" button. If the red indicator does
not go green like in the picture below, you need to determine the cause of the fault. You can do this
by bringing up the BLEPS screen for the station which indicates a fault.
|
| 2. Station fault indicator screen |
|   An BLEPS interface screen for an idividual station is shown below.
Which ever component is in fault would have a blue (water), yellow (temperature), or green (vacuum) indicator
above the component. If the fault is a water or temperature fault and does not reset by pressing the button
above, contact a beamline staff person. If it a vacuum fault and you still can not take beam after clearing
it you, need to open gate valves. These valves are closed to prevent the propogation of bad vacuum in
case of a true leak. Most frequently, however, these are just temporary vacuum spikes and you can simply
open the gate valves . You can access the valve interface using the "Valves" button on the top
of this screen.
|
| 3. Valve interface screen |
  The interface screen for opening /closing the vacuum gate
valves is shown below. This screen is showing two closed valves that need to be opened. Simply press
the "open" button on both of these valves. If the fault has not been cleared by hitting the
reset button a yellow box will appear indicating that the permission to open this valve has not been
granted. If permission to open the valve is not granted after pressing "Reset EPS" then the
vacuum is out of the programed range and you will need to call one of the beam line staff to determine
the problem.
