If you are present at a power-failure, prepare the Emergency-Power-System (in D320 Mg-Lab next to the electronics/chemistry cabinet) and get gazoline (Super Benzin)
At (severe/long) power failure
Set up the emergency power system (EPS) on the balcony room - (Parameters to turn it on: Choke: Turn off, Gas: Turn on)
Disconnect the marked power-cord (next to “Notaus”) from the power-plug and put it into the EPS. Now, the turbo-pumps and IGP should be save
If the turbo-pumps fail: Close the big valve below the chamber-table for the big turbo pump and turn off the big turbo.
Things to do after power failure
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
Most probably the ACs will fail after a power failure
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)
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
