Thankyou Ai for your contribution but I think your search engine is not running on all cylinders.

What is the make and model of the light? It may have an inrush current that is too large for the switch.

The check valve is a parallel path inside the inline flow control, zoom in on image in previous post, schematic on side.

When you actuate in the opposite direction you are not causing pressure loss, you are pressurising the side of the cylinder that will be exhausted when you actuate in the correct direction, the pressure is needed as you are currently controlling flow from your exhaust ports. When the valve is in...

When the valve is in the centre are the A and B valve ports blocked or connected to exhaust? If they are connected to exhaust that would be the cause of pressure loss inside the cylinder. If they are blocked any small leak in the lines, cylinder or valve would be the cause of pressure loss...

The air cylinder actuates at a very fast rate because there is no pressure in the cylinder side that is being exhausted, so there is nothing to regulate on the exhaust ports. Post a pneumatic schematic of your system if you need more help, extra components or different piping arrangement could help.

Buying off-the-shelf automation components is the simplest way to implement a Profibus network. The PLC is the master and IO, drives, etc are the slaves. The PLC programming software is used to setup the whole network within the hardware configuration, this is then downloaded to the PLC.

How are you trying to remote control the speed? Analog input? Fieldbus?

If you just want on/off format for the screw then you just need a suitably sized contactor. C-more HMIs seem to be made to go with the Click PLCs so that would allow you to enter the weight

The more expensive the motor the more layers of protection you should have. While you can risk it and run without the RTD, you really should plan to have it repaired during planned maintenance. Hopefully the cost of repairing the RTD is cheaper than replacing the whole motor.

If I was alternating pumps with a PLC program, I would have lead/lag code. Before the first pump is started it selects the pump with the lowest run hours as the lead.

Good to see you are making progress. I am not sure why you have the jockey pump off, I thought it would be useful to make up pressure with low or no flow, a larger pump would not be required to start. One step at a time is good but at some stage there will need to be a big step to replace the...

The secondary voltage of the VT should be low enough to be within the input limits of the energy meter, sometimes VTs are not required if the mains voltage is low enough. You also need to specify the accuracy class which all depends on what you are using the energy meter for, tariff, reference...

It is just a ratio to multiply the secondary voltage of the VT so the the energy meter can calculate the primary voltage of the VT. Keep it simple, 440:110 or 4:1

Regarding the sentence that is underlined in red, this may be about some PID controllers where actual effect of Ki and Kd are multiplied by Kp

Does the "invert control logic" option need to be changed so the PID controller is reverse acting?

As a second pump is being called, it seems like the pressure switch is not switching off either due to pressure switch fault or not enough pressure from pumps. Are there any indicators on the relays to tell you they are energised? LED or mechanical indicator. You could video these while problem...

Yes High System Pressure Tripped and Low Suction Pressure tripped will stop the system and trigger the alarm. The Low System Pressure Tripped will start the pumps, the same as the Call pressure switch. I presume it should never get this low under normal operating conditions. When pump 1 is...

The ladder diagram is not too complex, I have provided some information below, if you get stuck I can provide more. If you want to develop your knowledge you will need to gain an understanding of a relay holding circuit, delay on timers and minimum run timers. One of the sheets you posted lists...

Please provide details and dimensions of what you are cutting with the bandsaw. AOPD and muting might be a solution but need more details. The cost of safety is a lot cheaper than the cost of an operator being injured. Signage is an administrative control, this should only be used if the risk...
