Your challenge is one analogue I/p ... which FX do you have mind - assuming you will have 0-10vDC and would measure range 0-15vDC from the battery. What accuracy do you think you can achieve by perhaps a voltage divider. Apart from scaling this analogue, what you want to do with the measurement ?

The fundamental difficulties are - the infrequency of failure - not understanding the cause I would be inclined NOT to uprate the fuse. Despite being fast acting, at some point the 20ma loop current has been grossly exceeded for a short finite time. They are the loop‘s best protection. My...

Mindful I am not familiar with Mervis but am with Siemens..... You edit the FB by adding instruction to map the integer values into an area of unused memory. If you can't edit your FB then you call another FB which runs for the same one scan cycle and map the values in the same way. If done...

Presumably your block algorithm is close to a flow diagram / flowchart which almost makes sense. What you describe as ladder logic is total nonsense....you can’t think of a moisture sensor in Boolean terms when it is an incoming variable to your process. Does the pump move water, if so where is...

You could say Yes, but you could also say No........ Would you run 2 core for 500mtrs then tell me there is 90volts on a 24vDC digital input ? Would you run this 24vDC digital signal in a 27core cable which has other prewired cores with 240vAC digital signals. Would you use 2 core armoured or...

You might say my description above could be a small part of a Functional Description ... My conclusion is that Cyclograms and specifically ladder logic are really, not entirely compatible. There must be hundreds of examples where PLC's perform a function which isn't covered by Cyclograms...

According to my information, CSI 4500 is an Emerson product. Non of the Entek range I came across had potentiometers - parameters are all pre-programmed. Offset on Entek was non-adjustable - approx. 11.5vDC for Supply 24vDC. Sounds to me you need a Manual - I’ve never found Emerson all that...

The monitoring system is the area of focus not each sensor. I’m assuming you have a 3500 rack. Ultimately for proper calibration you need to pull in a Bently Nevada engineer or agent. Each proxy sensor needs to be mounted with a physical gap between sensor head and shaft according to...

To write PLC coding you need a little imagination which helps. Looking at the op’s 2nd diagram: The Output could be energising a water pump which fills a holding tank. Operation is manual by way of start push button (PB) and stop PB. Polarity of the stop PB is correct for a normally closed...

I believe I see the op’s problem - no experience of electrical/electronic engineering, just a bit of logic experience. To write PLC software, you need to know exactly how the PLC performs; more important you need to know exactly how each machine works that you are controlling. And as most is...

The growth of AI has, like any new area of science to be taken cautiously: https://www.bbc.co.uk/news/technology-56745730 Europe seeks to limit use of AI in society I can envisage many conflicts of interest eg. cyber security

OK when you mean fibers in the tank, you mean tank wall. Guessing it’s a failed weld or crack in the steel casing - it’s failed the pressure test ! You don’t know how these cylinder have been treated in the past. It’s not unusual to have them dropped or handled Roughly.

If you know anything about pressure vessels then you will know fibre washers are commonly used to seal (screw) joints but have a limited life so are regularly replaced.

What do you mean by ‘HV contractor’ ?

Looks like a Flip-Flop, but also a simple start/stop circuit. For beginners, for me it has always been the standard traffic light which has a simple sequence to work out. If you are University material, rather than search for solved examples, you will learn quicker by trial and error; and there...

It’s unclear what you are trying to achieve - you have provided a link to what you want but something ’for cheap’. I guess the cheapest way is to make it yourself which you have alluded to. The pump appears to me the single most expensive item, and as you are in a Control Forum, I would look...

Are you aware that ‘playing’ pressure testing is dangerous and that for formal pressure testing there are Statutory Procedures that must be followed by competent persons (in the UK but similar regulations will apply elsewhere). The 30bar pressure test is for the cylinder construction - what is...

You better tell us what you mean by triggering voltage. Industrial contactors snap close or snap open - there is no inbetween. So in a 24vDC design the contactor coil receives 24vDC or 0vDC. In a commercial vehicle 24vDC is commonly used - contactors give isolation. Looking at bus design where...

I worked on S5 over 20years ago and they were discontinued then ! The Software was STEP5 which ran on CPM and later DOS3.0. Have you got the application program to download ? The controller could be completely broken or could be flat battery (I believe there was EPROM versions where battery...
