| + | ====== Shutter ====== | ||
| + | The dome shutter must be opened prior to observing and should be closed to protect the telescope during the day or during inclement weather. Remote observers may open the shutter no earlier than one hour after sunset and should close the shutter one hour before sunrise. Fully opening or closing the shutter takes about 10 min. When operating the shutter, please watch both the antenna status display and the [[http://cso.caltech.edu/webcams.html|webcambs]]. | ||

| + | ==== UIP commands ===== | ||
| + | |||
| + | Under normal circumstances, the shutter is operated from the UIP. | ||
| + | |||
| + | * Open the shutter with: \\ ''__UIP__> shutter /open //NN//'' \\ where //NN// is the (optional) opening percentage. If //NN// is not specified, the shutter will open completely (95% open). | ||
| + | |||
| + | * Close the shutter with: \\ ''__UIP__> shutter /close'' | ||
| + | |||
| + | |||
| + | ==== Troubleshooting ==== | ||
| + | |||
| + | Please inform the staff if any of these procedures are necessary. | ||
| + | |||
| + | === Controller reset === | ||
| + | |||
| + | On occasion, the shutter controller gets confused so the shutter does not operate. If this occurs: | ||
| + | - Reset the controller. \\ ''__UIP__> shutter /reset'' | ||
| + | - Wait a decent interval (several minutes) and attempt operation again. | ||
| + | - It may be necessary to restart the antenna computer. \\ ''__UIP__> antenna /restart'' | ||
| + | |||
| + | === Manual operation === | ||
| + | |||
| + | If resetting the controller does not help, the shutter may be closed manually. | ||
| + | |||
| + | == Control room == | ||
| + | |||
| + | On the control panel in the control room, push the black //Close// button, indicated in orange in the photo. This button is just right of the red //Stop// button. The value on the numerical LED display should decrease. The shutter drive will stop when the shutter is fully closed. | ||
