Dear Friends,
I am new to this thread so please excuse anything i may get wrong. We are trying to assist a client with a very old schindler relay based elevator. we are looking for similar electrical type drawing and perhaps a lift of symbols and their meanings. we are not familiar with schindler relay systems . i have attached a picture of the controller and a name tag (can anyone explain what this name tag means). The equipment has wooden swing doors so we are keen on understand the lcok circuit .
thanks,
shaun

it kinda looks like it has a Flux Capicitor on it...Good Luck!

Those are prolly Patent Numbers
