Si what are those in the door.? They look like Switches.? but what are they controlling.?

[GTJim]

Si that looks very good and if i can get mine laid out as well I'd be happy.
Do you have any fans in the cabinet and are they needed?

Where did get the terminals and isolation switch?

Dean, they're just LED lamp holders. One as a 'ac power on' indicator (so I don't forget to switch it off!), the other connected across the NC terminals of the contactor to show when it's not latched on.

Thanks Jim. There are 2x 24v fans in the cabinet. One can be seen just below the BOB pulling air in, the other is at the top in the middle pulling air out. I could have got away with just a vent at the top, but as I had 2 fans and a load of filters I thought i'd use them.

The Din rail terminals are these : EK2.5 - Detailed item view - Chalon Components and these : JXB2.5 - Detailed item view - Chalon Components

The isolator switch is this one : Buy Non-Fused Switch Disconnectors 32A 3P Door Interlocked RS LBDI323P online from RS for next day delivery.

Ah ok for a mo I thought you'd put Reset button and stuff in door instead of on machine and trying to send me bonkers. . .Lol

Lol, no mate. 24v on/off switch, reset, e-stop, limit override and feedhold buttons should all be on the machine control panel.
I added a lamp on the contactor as I've been caught out a few times at work when e-stop buttons have accidently been pressed while a machine was powered off. Then i've gone round checking guards and fuses before i've realised why there was no life in the machine when I switched it on :/

Have you been using the machine then and got a feel for the kind of temperatures reached in the panel ? I was hoping to use just a vent on top myself with 2 fans sucking in via filters.

A bit like you I've been working on the control panel before the machine. I've no idea what the temps will be inside the panel during use. I didn't really have space for both fans on the bottom gland plate. I figured the one at the top should help evacuate warm air from the drivers' heatsinks, hopefully it will also prevent dust settling on top of the vent/filter during use too.

The reason I put mine on the door was because it's wall mounted and right next to the machine, I got a wireless MPG pendant that I'll be using most times.

Ah ye your probably wondering why it might send me bonkers.?. . Lol . . . I'm building the machine for Si and we are putting Switches, Reset and E-stop, feedhold etc in control panel on front of machine so when I saw what looked like switches in door I thought we'd got ( Get ready for the Pun.!!) . . Crossed wires . . Lol
