   * If the turbo-pumps fail: Close the big valve below the chamber-table for the big turbo pump and turn off the big turbo.   * If the turbo-pumps fail: Close the big valve below the chamber-table for the big turbo pump and turn off the big turbo.
  
-====== After power failure ====== +====== Things to do after power failure ====== 
-<note important>!!!Most probably the ACs will fail after a powe failure!!!</note>+There are two power-failure situations. One, where a fuse or the Notaus in the lab has triggered the power failure and then one, which happens for the whole IQ/UNI. The later one needs an additional treatment.

 +===== Whole IQ/UNI power failure ===== 
 +<note important>Most probably the ACs will fail after a power failure</note>
   * Turn off every device (Oscilloscopes, commercial systems etc) and all the power supplys in the "Stromschrank" to avoid uneccesary heating of the lab   * Turn off every device (Oscilloscopes, commercial systems etc) and all the power supplys in the "Stromschrank" to avoid uneccesary heating of the lab
   * Check if the AC is working again (call 4440 to tell them or wait for the next day until it's fixed).<hi #ed1c24> Indication for a not working AC</hi>: The red light next to the WC/KRb Office is flashing (but musn't)   * Check if the AC is working again (call 4440 to tell them or wait for the next day until it's fixed).<hi #ed1c24> Indication for a not working AC</hi>: The red light next to the WC/KRb Office is flashing (but musn't)
 +  * If ACs are working again, turn on every single device again.

 +===== Checklist of devices =====
 +**Vacuum**
 +  * Check if all pumps are running and all pressures are ok
 +  * If pressures and pumps are ok (especially pre-vacuum and turbos) open the pneumatic valves (Next to the Lab-Door, there is a orange interlock. Press the reset button. You will hear the valves)
 +  * Open, if it has been closed, the big valve below the table at the big turbopump
 +
 +**S-MOT Laser**
 +  * Turn on the Toptica controler (green button)
 +  * Check the temperature controler of 285
 +  * If a PID does not seem to work (e.g. Offset cant be set): Unplug it from power and replug it.
 +
 +**Triplet Laser**
 +  * Turn on the Thorlabs TECs for the Laserdiodes (they turn off on a power failure)
 +  * Turn down the current for every laser-diodes (even when the controlers are still off), turn the controlers off and set the short button to short
 +  * Reenable the powersupply for the LD (in the Stromschrank): Orange interlock (Press the reset button)
 +  * Turn on each laser controler. Then un-short the diodes. The ramp up the current
 +  * If a PID does not seem to work (e.g. Offset cant be set): Unplug it from power and replug it.
 +
 +**Wutz**
 +  * Turn on the Toptica controler (green button) - If it does turn off itself: Wait 15 minutes for the TECs to settle and try aganin.
 +  * Turn on the EOM-Synthesizer (located on bottom of Dipole-Rack) and set it to the correct frequency (written on the device - Recall, 9, Enter)
 +  * Monitor for Wutz/Clock-Laser: In the menu, go down to PIP (Picture-in-picture) and press right: It should enable the Wutz cam on that monitor again
 +
 +**Lattice Laser**
 +  * Check if the Meerstetter for the TiSa is working (green LEDs)
 +  * If a PID does not seem to work (e.g. Offset cant be set): Unplug it from power and replug it.
