1. Current situation – Motivations for change:

Schneider NANO PLC completely obsolete. EL control of CV equipment.EL control of GS/ASE equipment (fire/gas).Use of PLC requires pro-active management.Current system overly complex.

Time for a new, simpler, solution…

2. Requirements definition

From IS5:AUL Purpose:AUL - specific features: cut off power sources situated inside or serving a geographically circumscribed position or installation.Areas to be equipped:AULs must be installed in restricted premises or areas that are clearly demarcated such as workshops, laboratories, barracks and similar areas and/or other types of plants with risks greater than those of ordinary domestic appliances or office equipment.

19/05/15 Nano PLC Replacement 6

2. Requirements definition

From IS5:All AUL actuators at a given point, or those of an AUG in a building or hall must have the same effect.

2. Requirements definition

Major event 2012 – ALPHA experiment power cut due to Nano.

Additional user requirements, defined by EN/MEF with HSE, GS/ASE, EN/EL and EN-DSO for Secondary Beam Areas (SBA’s):• Covers each system, AUL, AUG, ODH,

Gas, Fire and Temperature.• Ability to cut electrical power to a

defined zone or zones upon the activation of either a manual switch or automatic interlock with another system, notably ATEX gas detection.

• Maximum granularity and flexibility for the selection of zones in which emergency electrical power cuts may be affected.

• A highly reliable system, fail safe and suitable for life safety applications.

19/05/15 Nano PLC Replacement 8

2. Requirements definition

EN/EL requirements:

• Compatibility with new philosophy using contactors as a replacement for MN coils to reduce the call out requirements for the EN/EL piquet service.

• A cost effective system which can be maintained without major intervention, replacement or upgrade for a significant period of at least 25 years.

• Enhanced indication of the location of AUL chain trip events (manual or interlock) to facilitate interventions.

19/05/15 Nano PLC Replacement 9

2. Requirements definition

Summary:

• A simple, reliable and modular system.• Suitable for various topologies of experiments and

physics barracks.• External input from Gas Detection only.• Indication of activation for faster Piquet intervention.• Can be reset by deliberate user action.
