Why a new DQLPU type A?
• To improve protection of 1232 dipole magnets thanks to:
Integration of the enhanced quench heater supervision Compatibility with new fully redundant linear power supplies
• Remote commands,…

Crate supervision unit:• Supervise all
voltages. • Test presence of
the current loop. • Remote power
cycling. • 1350 boards to be
produced.
For future upgrades
Quench heater supervision unit. • DQHDS voltage
measurement.• Fast current and
voltage recording during a discharge of DQHDS through the Heaters.
• 1350 boards to be produced.
Fip connector + DQAMC• reprogramming connector and future
nanoFip board emplacement. • 1350 boards to be produced.

Why during LS1?
What are the risks and/or the impact if not done during LS1?
• More physical interventions will be necessary due to more SEUs on uFip circuits (higher energy).
• Risk of not detecting fault in quench heaters.
To take advantage of this long shutdown • To improve the reliability of this equipment. E.g. fully redundant power
supplies. • To have more diagnostic tools such as the state of the quench heaters or to
localise a interruption of the quench loop current . • To save some physical interventions by some remote commands. Remark: Old DQLPU_A is highly dependable. Might be difficult to reproduce this dependability, given the increased complexity of the new system.

Safety measures
• Personal safety:
Bd.281: standard procedure like any other laboratory space. No particular risk to test the DQLPUs, except for the Hipot test at
2.5KV, which will require H1T/H2T habilitation.Safety inspection required with EE (Mathieu) for the machine tools and
mechanics space.
• Tunnel equipment:
As usual, but access only required for uninstallation and reinstallation. All the DQLPUs must be cleared by RP before taking them out and NO
destructive operation foreseen on the reused equipment. That means no soldering work on them.

What SW tools are planned to be used? Are they ready to be used? Who will provide them?
Before installation
• Firmware DQLPU + all circuits boards: EP (internally)
• Test bench: DQLPU functional tester: EP --> LabWindows/CVI
• Functional test DYPB: BE-OP>LabVIEW
• Working progress
After installation
• QPS console (QPS expert): Java: managed by BE-OP, EN-ICE
• QPS high level supervision(PVSS): EN-ICE
• Configuration database: MS section
• Post operational checks: to be defined but probably MS section
• Analysis of Quench heater data: to be defined, but probably by MS or PE section (in Java or LabVIEW)

Questions
• Is there any benefit to further automate the process of your tasks (testing, commissioning)? YES
What would be the effort implied?
– Automatic tools for commissioning IST. E.g. interlock tests. To be defined.– Current tools already done in LabVIEW but might be better to move them to Java.– Work package for MS section (to be defined).
• What is the long term strategy regarding to maintainability of testing equipment and related software?
– Test benches will be maintained by EP section (Building 281). – Tools for system exploitation: there are still LabVIEW and Java based tools: common strategy to be defined
to have a unique platform. • Do you foresee other potential showstoppers? (Like delay for supplying components, administrative constraints..).
– Implementation of the power supplies redundancy in DQLPU type B: to be done on-site (no external resource).– In case of problems it must be understood that the DQLPU upgrade and the R2E activities are critical for the
restart of the machine (priority must be given).– Other less critical tasks may be delayed if necessary, during Christmas shutdown for instance.– FinanceTE

Tests to be performed to verify the quality of
the transmission of signals before
