5. Commissioning steps (1/2)
In general Commissioning is a Verification of functionality (hardware + software debugging phase)
Installation of PLC, WebMas and PVSS software
Test Profibus and CANbus lines from PLC to field nodes
Cable check from control racks to gas racks
With control interface we take output objects into manual mode and operate them (valves, pumps, MFCs, LEDs,…)
For input devices we:
Take off the device-connector in the rack and observe the state change on the control interface
Provoke a reading with a change of pressure or flow in an other part of the system.

6. Commissioning steps (2/2)
Activate first set of parameters
Verify new functionality (where applicable)
Eg MDT mixer with liquid injection,- or RPC humidifier
Verify chamber pressure interlocks
Verify leak tightness of inter-area piping
Run gas through chambers
1) computers
2)+3) cable IO check
4) 1st parameters
5) New functionality
6) interlocks
7) Leak tightness
8) Gas to chamber

10. Most commonly found mistakes
Cable + pneumatic lines
Swapped
Wrong labeled
Come to wrong rack in UX
Cut
BUT: - “Whatever can be fixed within one day is not considered a mistake !”
- MDT has 304 pneumatic lines of which only ~ 15 were wrong !!!

Conclusions
Commissioning procedures are very well tuned by now.
The teams ( ours + IT/CO) work extremely efficiently
ALICE and ATLAS systems will be ready to deliver gas to chambers by end Jan 2007 (installed racks only)
By about July 07 all gas systems (but TOTEM) will/should be commissioned
No “show stoppers” in sight so far (let’s keep fingers crossed…)
