You are on site, and you do Ex detailed inspection.
There are:
- a motor - Ex de - cat2 solution - T4
- a pump - Ex c - cat3 solution - TX
- Pt100 temp sensor - Ex ib - cat2 solution - T6
Only doc available: DoC of motor.
HAC: Zone 2 IIA T3
Questions:
- is it enough to comply with Ex requirements? No.
- is it assembly or individually sourced items mounted here locally? No one dataplate, so probably option 2.
- Ex c might mean nr of requirements, E.g TX, and what about dry running, pressure values, transported materials, …
- as of extra motor is with VFD, so temp monitoring shall be an issue.
Even here the min shall be per item:
- proof of Ex compliance, here: ATEX
- IOM
- dataplate
- design variables
Keep up good work!
Actual result: failed.
Ps: show must go on.
