thanks panic mode for the info i will have a look at the catalogue and also see if i can speak to a representative also thanks again sp4rky

hi guys i've got a little job to do where i need to link a photo diode amp unit to a control station. The problem i have got is that the customer would like us to use Harting connectors. Although i have used them in the past i have never had to spec them !!!! I'm looking at needing a 220v Live, neutral & Earth to be linked, a 24Vdc + & - supply and an analogue 0-10v single signal wire (!!! the reason for the single analogue input is our i/o homebrew module only has a single input terminal type architecture (mainly used in digital inputs)). Would you suggest using seperate plugs cable ways? I would like to do it in one plug/socket arrangement because i am limited for space on the amplifier module enclosure!! Can the harting plugs be used with different wire/cable types ?? Ordinarily i would have used a beldon screened cable for the analogue signal, then used standard singles for 24 & 240V supplies Any ideas are welcome sp4rky

In final throws going to evaluate a couple of packages and wondered which to shortlist? Any feedback is welcome

Hi guys, again i could do with some input i am starting to translate some layout drawings that we have for our electrical panels into schematics. In the past the schematics i have had were all paper based as i never got electronic versions. How would i be best laying out schematics on ACAD Lt !! Should i do all the rungs in model space and layout 10 rungs into a viewport ?? I really am unsure. I know its going to be a pain and i could/would be better suited getting ACADE or the like but to start with my boss is unlikely to shell out nearly £4K. Which system do most peeps prefer vertical rungs (similar to ladder logic) or horizontal (similar to many german/euro schematics) thanks again for any input cheers sp4rky

Hi guys i'm after some best practice info please on screening. we manufacture equipment that uses sanyo denki stepper motor drives for x and y axis movement. The motors are supplied via a 4c and earth screened cable. Looking from previous drawings we have on our system it would appear that some drawings have the screen grounded at one end and some drawings show it grounded at both ends. I have always been used to grounding the screen at the transmitter end, so in my case at the control panel end where the drive card is located. have any of you guys got any comments or suggestions on what/how i should approach the screening issue. I just want to get a standard (if possible) way of manufacturing the equipment. I am led to believe from past history that interference was an issue but no one logical step was taken, it was always more than one countermeasure actioned and nothing documented. any help is appreciated. Cheers sp4rky

cheers fellas much appreciated what sort of costing would i be looking at for ACADE in the uk? chako: i have downloaded that already thanks and have had a look at it. what sort of size grid spacings do you use ???

thanks again for the replies are there any demos of ACADE ?? its quite expensive and i would ahve to justify spending £4000 plus on this software plus is the maintenance fee per year really needed ???

thanks for the info will have a browse thru thanks again Carl

This question has probably been asked before but what the hell. I've just been given the job of doing the electrical drawings within the company i work for. i have obviously worked from drawings in the past whilst working for major manufacturers like toyota and kvaerner to name a couple. We are currently working from what i would call layout drwaings ie panel builder works to them, they are nowhere near a schematic, and we are using ACAD LT to compile them. The equipment we manufacturer is for use in the glass industry and mostly adapted to suit needs. This means alterations are usually made to existing drawings but this is so time conuming that its unreal moving sets of wires adding, and i could go on. I have a number of questions being new to the draftsman role !!! One is there a set standard i can work to for panel layouts including wiring standards (just to give you an indication that we use RS traced cables 17 colour combinations and repeat use for different inputs outputs !!!! which worries me) I have use JIC symbols previosly but wondered if this standard included best practice so to speak for panel wirng in general Is there an all in one package i could use that will let me do a schematic then translate to a panel layout. Whats the best system for cable marking (not critchley markers though they take too long). I want to steer away from the 17 colours and introduce a system such as a Blue wire is 24vdc, Red is upto 220VAC, and subsequently identify them with a wire number Any feedback would be appreciated Cheers sp4rky
