I couldn't find it either after getting the messages, and just assumed it was this forum 'New to RE'.

Re: Introduction Forums
Hi. I am new to the site so I may take the advice to remain silent and be thought of an idiot, rather than let my key board remove all doubt !
However, I do need some help from someone please ...
I found an old posting regarding Screw Compressor rotation. Can anyone help me find a formal reference to an ISO standard for power supply direction of rotation in relation to the power supply rotation direction ?
In my business we rewind Screw compressor motors for a living and I need to establish a clear technique for eastablishing a standard direction of rotation for a production rewound compressor, plus how this can be properly verified by a client's service engineer with relatively low knowledge level on how to check this, preferably without actually switching the machine on - the suction gauge falling check on start up to be used as a final verification only, rather than the primary check.
Can anyone help me ?

Re: Introduction Forums
Nice to see you here, Chris.
We discourage direct promotion on this site, also, one post is sufficient in any case.
We hope that you continue to post on this site and join in the discussions.

It is possible to obtain an instrument with signal lamps to check rotation regarding phases but that can be done at site.
Check this link and see about some solution from Bitzer,

Look for INT389R and read it

The direction of rotation can be different for screw compressors. Some are male rotor driven, others are female rotor driven. This needs to be verified with the manufacturer.
For the open drive compressors with motor couplings, the center member is removed from the coupling hubs for a "bump test" to check rotation.
For semi-hermetic screws you can't do this check. You can do this is the field before start-up. As Josip suggested you need a phase rotation meter to verify the direction of rotation. This must be done before the compressor is energized!
...how this can be properly verified by a client's service engineer with relatively low knowledge level on how to check this...?
Either you provide a statement that the motor rotation should be checked before start-up or the owner has to call a professional.

I'm not sure but I think everyone can add a signature in his private profile. Isn't it?

What is the signature for?
After you have registered, you may set your signature. This is a piece of text that you would like to be inserted at the end of all your posts, a little like having headed note paper.
If the administrator has enabled signatures, then you will have the option to include your signature on any posts you make. If you have specified a signature, then the forum will automatically append your signature to any messages you post. You can disable signatures on a per-post basis by un-ticking the 'Show Signature' checkbox when you compose your message.
You may turn the signature on and off on posts you have already made by editing the post and altering the state of the 'Show Signature' option.
You can set your signature by editing your profile.
