Auma actuator, valve didn't run in remote mode, what is the problem?

The valve is running in local mode, but in remote mode it didn't run. Attached the wiring related. I measured 24 v between terminal (4 and 7) for close feedback. But the valve didn't close or open.

Need help please.

kehili,

When did this problem start? After some kind of work was done on the valve and/or actuator (the AUMA device)?

I don't really see any signal to tell the AUMA actuator and valve it's in AUTO (local??) or REMOTE. Everything above the dashed line at the "top" of the drawing appears to be external to the AUMA actuator/valve assembly. There is 3-phase power, some 24 VDC, the OPEN, CLOSE and STOP signals to the AUMA actuator (at terminals 4, 5, 6, & 7), some kind of external "safety" interlock (which may or may not be used on your application), and everything else (terminals 14-23) is an output, either analog (4-20 mA) or discrete (open/closed contacts). So, it would seem there is some kind of external switch (above the dashed line) which is used to differentiate between a local OPEN/CLOSE switch or a remote OPEN/CLOSE signal, such as from a DCS (Distributed Control System) or a BOP (Balance of Plant) controller, or something like that (maybe). Because if the valve moves when the external AUTO/REMOTE switch is in AUTO, then it should also move when it's in REMOTE (presuming what ever is providing the contact closures to the inputs is also working, and the wiring is all correct).

It's possible that the external switch isn't working correctly (to select between AUTO and REMOTE) or the equipment that is to be sending the remote OPEN/CLOSE signals isn't working correctly, or the wiring between the external switch and either the remote system OR the external switch and the valve mechanism is bad.

But, usually when things like this happen (something which was working suddenly stops working) there is a reason.... Such as the valve and/or actuator was removed for some kind of maintenance or repair, and was not re-installed/replaced properly.

Thanks for providing the AUMA drawing, but what we really need is the "external" control wiring drawing--the circuitry above the dashed line at the top of the AUMA drawing. THEN, we might be able to be of more help. But, if you can identify what was done around the time the problem started, you might be able to help yourself solve the problem.

BUT, since you wrote here asking for help, please write back to let us know what you find and how you resolve the problem. If you need further assistance, please answer the questions below and provide the external control wiring drawing.

1) When did the problem start?
2) Is there an external switch to select AUTO (local) or REMOTE, and OPEN CLOSE buttons for the AUTO (local) mode?
3) Is the REMOTE control(ler) working properly (is it in the proper mode of operation to send signals to the AUMA actuator, and is the external AUTO/REMOTE switch working correctly?
4) Have you verified all the wiring per the external control drawing to be correct and properly terminated (no loose connections; wires at the proper terminals; etc.)?

(It is important to note that I am presuming--because you didn't tell us--that AUTO means "local" and REMOTE means from a remote control system. If you write back for more assistance and AUTO means something different, please let us know; or if REMOTE means something different, please let us know.)

Best of luck--and we are expecting to hear back from you on how you fare in resolving the problem, or providing the requested information if you require more help.
 
Thank you for your reply.

In fact, Local means to run the valve manually (using valve buttons), the selector is in Local position. And Remote means giving command from PLC (Open or Close), the selector is in Remote position.
Please find attached the loop diagram for your reference.
The valve didn't open or close when giving command from PLC, be known that 24V is measured in the terminal (4,7) and (5,7) for close and open command.
Also, I tried to run in remote mode from the valve with making jumper between (1 and 4) and (2 and 7) because the valve can provide 24v, but the same problem.
Be informed that it's new installation, it didn't run before.
I think there is a configuration that I have to do in the valve but I don't know which.

Need help please.

Hello

Here some notes from OE manual,...

I strongly suggest you to get it and read it carrefully as everything needed for operation & maintenance of the device is well described &explained...

Operation mode Remote
Selector switch is in position Remote control (REMOTE).
Characteristics The indication in the top row of the display shows the set source of the operation
commands:
● Remote (parallel interface)
● Remote II (parallel interface, push button station)
Depending on the control, a distinction is made between:
● OPEN - CLOSE control (operation mode Remote OPEN - CLOSE):
Control is made via binary operation commands OPEN, STOP, CLOSE.
(or for activated Multiport Valve function via operation commands CW, CCW)
● Setpoint control (operation mode Remote SETPOINT):
Control via analogue operation commands, e.g. 4 – 20 mA.
Information ● Binary signals (e. g. +24 V DC) via digital inputs are only recognised as valid
operation commands if the signal is present for at least 10 ms.
● If a positioner or process controller is available, change-over between OPEN -
CLOSE control (operation mode Remote OPEN - CLOSE) and setpoint control
(operation mode Remote SETPOINT) is possible. Refer to chapter <Changeover
between OPEN - CLOSE control and setpoint control>.

kehili,

My suggestion would be to disconnect the "remote" wiring from the AUMA actuator and use a wire jumper (it doesn't have to be very long, with a small bit of insulation stripped off one end and the normal amount of insulation stripped off the other end to fit under the terminal board screws). Put the end with the longer bare wire under Terminal 7 and tighten it--being careful NOT to earth or short the other end of the wire to any other terminal in the junction box. Then touch the end of the wire with the small bare tip to Terminal 5--that should make the valve start OPENing. (I'm presuming it's closed.) Then lift the wire from Terminal 7 and touch it to Terminal 4, to make the valve STOP moving (if it hasn't already STOPped). Then touch the wire to Terminal 6 to make the valve begin to CLOSE. And, possibly just continue holding the wire on Terminal 6 to let the valve move to the fully CLOSEd position.

If this works--then there's a problem with the wiring between the PLC and the AUMA actuator. I already see that someone has made a field modification to the wiring, and I don't understand why it was made (and I'm not going to try to understand it). The purpose of this suggestion is to verify that the valve moves when the signals to the valve are correct--that's it. If the valve moves as expected with the jumper, remove the jumper and start working out what the intent of the PLC is, why someone believes it is NOT necessary to use the STOP command from the PLC to the AUMA actuator, and why the wiring isn't working correctly.

[I suspect that someone is trying to DOUT4 as a way of STOPping the valve when opening at some particular point, that is, not fully open.?.?.? If that's the case, has the DOUT4 switch been adjusted properly for that position? AUMA actuators are pretty slick and well-engineered devices--but they have to be configured (set up) correctly--and we don't know how it is to be configured or if it has been configured correctly. AGAIN, that's the purpose of using a jumper to simulate contact closures to make the valve move as if the PLC was controlling it. If it moves correctly, then that suggests the wiring between the PLC and the AUMA actuator is NOT correct, and it may also suggest that the DOUT4 contact is not adjusted properly if my suspicion is correct.]

Having said all of that, ControlsGuy25 is going to take over this thread (he has taken it over, actually) from this point. Please direct any correspondence to ControlsGuy25 as he has all the answers. (RTFM (Reading The Fine Manual) is a really good place to start for any problem like this. I apologize for confusing AUTO and local, but I think we got more information that was useful.)

The USUAL suspect for problems like this during start-up/commissioning is improper wiring. If you use the jumper as suggested and the valve opens and closes as if it was under the control of the remote PLC, then you have proven the problem is, indeed, the wiring. If you're not comfortable using the jumper to test the valve/actuator operation, then you need to find another job because this is a large part of start-up/commissioning and even plant maintenance and troubleshooting--using jumpers to prove or test operation. It's only 24 VDC and as long as you're careful and don't earth the wire to metal or allow it to touch other terminals in the junction box and don't grab the wire with one hand while gripping a hand-rail or pipe with the other you will be fine.

Best of luck! ControlsGuy25 is taking over from here. Please do write back to let us know how you fare in resolving this problem.

My Guess is if correct configuration has been done on site, as we are not prent there to check correct troubleshooting..

After have read the OEM manual, It appears that Remote selection ( switch ) & Remote operation mode are different things ...
I dont see that on the presented wiring diagram/drawing..
Are you sure about your configuration ( wiring , command signals. feedback signals..)

I am pretty sure that the device itself is not correctly commissionned /configured ..

Again I suggest you to have a carrefully read on the OEM manual..


Thanks CSA for your comments, but it would be great if we can sort it out all togegther , any help would be appreciated..

Looking to hear back from you soon,
ControlsGuy25.
