Electrical Abbreviation on P&ID, need help!!

Electrical Abbreviation on P&ID, need help!!

Electrical Abbreviation on P&ID, need help!!

(OP)
I have no idea what this abbreviation stands for:

LOR

It is on a motor starter panel with "START" and "STOP" pushbuttons.  It is on the same type of symbol as the start and stop so I am assuming it is a pb also.  Any help would be greatly appreciated.  The drawing came from a company in Bolivia so this has been all kinds of fun with the different styles of laying things out. I want to say this would be like a local jog but I am not sure.

Left Or Right ??  Change the directin of spin ??

In the power industry it stands for Lock Out Relay. Would make sense in your case as well, motor locked out and not going to start.

I have seen on site push start/stop buttons that turn to the right when you want to lock them from being pushed in to start unit. This maybe what it is for. Only really safe for local isolation.

RE: Electrical Abbreviation on P&ID, need help!!

Not sure how the symbols are drawn on your project. Perhaps it is a 3 position switch. Your guess is as good as mine.

One of the guys here is fluent in Spanish so we are going to conference call the company and try to get this figured out.  I will post what I find out.

We use LOR sometimes to abbreviate Local - Off - Remote.

Don't know if this applies here??

RE: Electrical Abbreviation on P&ID, need help!!

LOR is very popular for pump control in the Water industry for Local Off Remote

Mayo and sdb830 win the prize as this is what it turned out to be.  Sorry for my delayed response but I have been out of the office.
