* Call the Main Control Room (x3721) at the start and at the end of shift. This is required, and pleasant.
6 69 Jason St. John
* If the beam goes away for more than a few spills, look for Accelerator Alarms in ACNET (a default window). If the problem persists a few minutes, and you see nothing about it in the MCR elog, (or you just really want to find out more), call the MCR.  They're friendly, though they may be super-busy.

h2. *Trouble getting started*
54 152 Jason St. John
55 205 Luke Batten
* If you cannot ssh to FTBFLX machines: Get a kerberos ticket for yourself: @kinit <yourKerberosPrincipal>@, then ssh ftbf_user@ftbflx18 (or ssh ftbf_user@ftbflx15 or ssh ftbf_user@ftbf-cr-03).
56 216 Luke Batten
* If your Kerberos username and password are good, but you can't log on to FTBFLX[NN] machines:  Have someone who CAN log into those machines check that your kerberos principal appears in @~ftbf_user/.k5login@ in the LArIAT section (email the Run Co-ordinator at stjohn@fnal.gov). 
57 216 Luke Batten
* The same ssh errors may also apply to computers at ROC West. Troubleshoot using the above methods.

h3. Common failures:
64 187 Jason St. John
65 187 Jason St. John
* DAQ fails with @ERROR: ReadRegisgter ACQUISITION_STATUS CAEN_DGTZ_CommError BoardId 0@  wait 2 minutes, then try to start again.
66 187 Jason St. John
** Try issuing the command @lariatReset 0 1@ waiting more then 5 seconds, and trying again.
67 187 Jason St. John
This command is appropriate when one sees any type of "CAEN_DGTZ" error.  This command will NOT help the persistent ports error.
68 187 Jason St. John
* DAQ fails with @Found persistent communication port still open@
69 187 Jason St. John
** Wait 8 minutes for the ports to clear, then try again.

h3. Other failures:

73 1 William Badgett
* If the DAQ is having trouble talking to the crates, try issuing the command @lariatReset 0 1@ waiting more then 5 seconds, and trying again.
74 187 Jason St. John
This command is appropriate when one sees any type of "CAEN_DGTZ" error.  This command will NOT help the persistent ports error.

h2. *Wire Chambers*
78 152 Jason St. John
79 162 Jason St. John
* If the wire chambers are acting strangely: "remote power cycling instructions":https://redmine.fnal.gov/redmine/projects/lariat-online/wiki/Communicating_with_the_wire_chambers including mini-DAQ and telnet interface.
80 135 Jason St. John
* If the wire chamber system is skipping spill numbers, it may be a high trigger rate (> 30 k per spill).  The wire chamber controller may still be reading out the hits from the last spill.

h2. Power Cycle the ASICs (TPC Wire Noise)
83 168 William Badgett
84 168 William Badgett
* Anecdotal evidence has shown that analog noise on the TPC wire readout channels can be 
85 169 William Badgett
alleviated by power cycling the TPC electronics: ASICs and Warm Receiver/Drivers
86 203 Will Foreman
* You can remotely power cycle the TPC electronics.  Log onto lariat-gateway00.fnal.gov with X-forwarding enabled, type "firefox", and go to http://lariat-pdu02.fnal.gov.  Usename "ftbf" (password posted on whiteboard in MC7).  Choose the *CYCLE* option, which will automatically give a 60 
87 173 William Badgett
second powerless interlude.
88 173 William Badgett
* Further important informations can be found on the white board in MC-CR.
89 168 William Badgett
* This mechanism is controlled by a smart power distribution unit (PDU) located under the 
90 168 William Badgett
TPC electronics power supply near the cryostat in the enclosure.   Due to electrical safety 
91 170 William Badgett
rules you must *NOT* use any of the other outlets on this PDU.  Do *NOT* remove the protective 
92 168 William Badgett
outlet covers at any time.

* The readback voltage doesn't make any sense, is of the wrong polarity and/or is way above the nominal value, but just for a fraction of time
113 219 Flor de maria Blaszczyk
This is most likely just a glitch in the readout, please ignore if it happens once or twice. If it happens too frequently, power down the power supply (set voltage to 0), turn off the power supply and report it.

* Something went wrong during a ramp, I need to turn off the supply!
117 219 Flor de maria Blaszczyk
There is an interlock that prevents you from using the normal fast controls on the power supply when a ramp is on-going. First, *stop the ramp by clicking on the STOP button*. This will stop the ramp and clear the interlock. If you need to go back to 0 quickly, use the fast controls to set the voltage to 0 *and don't forget to turn off the supply!*
118 219 Flor de maria Blaszczyk
119 219 Flor de maria Blaszczyk
*Even if the controls appear not to respond, set the voltage to 0 and turn the supply off*. Contact Charlie Briegel first and describe the problem in detail. If you can and if it's safe, disconnect the SHV cable from the power supply. I
