Calibrating a Fisher™ 3582 Positioner - Zero and Span

[@xnavyro]

A point to note, on a 657 actuator saturation is necessary to ensure the plug has sufficient force to keep the plug seated against design dP which on a direct acting actuator, is the difference between the upper bench set & the regulator pressure. Conversely, on a reverse acting actuator, a 667, it’s important to ensure the actuator is fully vented at 0% of input for the same reason…

Hi I'm Jim Jones with Emerson 3582 in this video I’m going to show you how to calibrate this Fisher 3582 pneumatic positioner, as you can see it’s already properly mounted under this Fisher 657 size 40 I direct-acting actuator and the beam alignment has been double-checked so now we're ready to set zero and span, the zero adjustment is done with the nozzle, and the span is adjustment by moving the flapper assembly along the summing beam, we of course have our air Air Supply Plumbed to the positioner and can see on the supply gauge the regulator is set to in this case 20 psi, to get started we’ll move the flapper assembly to the mid-range of it's travel on the direct side of the summing beam or about to the number 6 on the scale, understand that the direct and reverse labels on this summing beam only tell us how the position or will react to the input signal and have nothing to do with what kind of actuator the positioner is on, don't be confused by that, second will increase our input signal to the bottom of the input range in this case three PSI, third will adjust the nozzle in or out to make the needle on the output gauge sit Softly on the zero pin of the output pressure gauge, step four is to slowly increase the input pressure but we'll watch the output pressure gauge as soon as the output gauge needle moves I stopped the input and look at the input gauge ideally it should be somewhere between 3 and 3 and a half PSI, this technique makes certain that when the input is at 3 the position output is saturated to 0 psi and the control valve is at one end of its travel in this case all the way open, now let’s set in step 5 of increase the input pressure but again I'm watching the output pressure gauge what I'm looking for here is saturation on the other end of the stroke, Saturation is identified when the output pressure rapidly changes and goes all the way to supply pressure, there it is, that means the valve has hit a stop and the positioner is applying full Supply to in this case provide maximum seat load, our goal is to make the position or saturate just inside the upper limit of our input signal that is in this case 15 psi, so when it's saturates ideally it should be between 14 and 1/2 and 15 psi, if we increase the input pressure in the output saturates just before or after our Target, which is just under 15 PSI we must move the flapper assembly to correct span and move the saturation point, this is step 6, if it saturates too soon or before 14.5 move the flapper assembly to smaller number, if it saturates too late or above 15 move the flapper to a large number every time you move the flapper assembly though you must go back and reset the zero adjustment and then check the span again when the 3582 positioner is properly calibrated we can be sure that when the input signal is at the limits in this case three and fifteen PSI we know that the valve is either wide open or in the seat with full actuator force, once the zero and span is set correctly don’t forget to tighten up all the lock nuts, so we can calibrate the 3582 positioner in just six steps, Step one, move the flapper to the midrange of its travel Step two, Apply a signal equal to the bottom of the input range Step Three, Adjust the nozzle to make the needle on the output gauge sit softly on the zero pin. Step four, Increase the input to find the low saturation point Step five, Increase the input and watch for the high saturation point Step six, Adjust the flapper assembly to adjust span and to move the upper saturation point.

Hola, soy Jim Jones con Emerson 3582 en este video. Les mostraré cómo calibrar este posicionador neumático Fisher 3582, como puede ver, ya está correctamente montado debajo de este actuador de acción directa Fisher 657 tamaño 40 I y la viga. la alineación se ha verificado dos veces, por lo que ahora estamos listos para establecer el cero y el intervalo, el ajuste del cero se realiza con la boquilla y el intervalo se ajusta moviendo el ensamblaje de la aleta a lo largo de la viga de suma, por supuesto, tenemos nuestro suministro de aire de aire Conectado al posicionador y puede ver en el indicador de suministro que el regulador está configurado en este caso 20 psi, para comenzar, moveremos el ensamblaje de la aleta a la mitad de su recorrido en el lado directo de la viga sumadora o aproximadamente al número 6 en la escala, comprenda que las etiquetas directa e inversa en este haz de suma solo nos dicen cómo reaccionará la posición o la reacción a la señal de entrada y no tienen nada que ver con el tipo de actuador en el que se encuentra el posicionador, no Confundido por eso, segundo aumentará nuestra señal de entrada a la parte inferior del rango de entrada en este caso tres PSI, el tercero ajustará la entrada o la salida de la boquilla para que la aguja del medidor de salida se apoye suavemente en el pin cero del medidor de presión de salida; el paso cuatro es aumentar lentamente la presión de entrada, pero veremos el indicador de presión de salida tan pronto como la aguja del medidor de salida se mueve. Paré la entrada y miro el medidor de entrada idealmente, debería estar en algún lugar entre 3 y 3 y medio PSI, esta técnica asegura que cuando la entrada esté en 3, la salida de posición esté saturada a 0 psi y el control la válvula está en un extremo de su recorrido en este caso completamente abierta, ahora configurémosla en el paso 5 para aumentar la presión de entrada pero nuevamente estoy viendo el manómetro de presión de salida. Lo que estoy buscando aquí es la saturación en el otro extremo de la carrera, la saturación se identifica cuando la presión de salida cambia rápidamente y llega hasta el punto de suministrar la presión. Ahí está, eso significa que la válvula ha alcanzado un tope y el posicionador está aplicando un suministro completo para, en este caso, proporcionar la carga máxima del asiento. nuestro objetivo es hacer la posición o saturación justo dentro del límite superior de nuestra señal de entrada que en este caso es de 15 psi, por lo que cuando se satura idealmente debería estar entre 14 y 1/2 y 15 psi, si aumentamos la presión de entrada en la salida, simplemente saturamos antes o después de nuestro objetivo, que está justo por debajo de 15 PSI, debemos mover el ensamblaje del colgajo para corregir el intervalo y mover el punto de saturación, este es el paso 6, si se satura demasiado pronto o antes de 14.5, mueva el ensamblaje del colgajo a un número menor, si se satura demasiado tarde o por encima de 15 mueva la trampilla a un número grande cada vez que mueva el ensamblaje de la trampilla, aunque debe retroceder y restablecer el ajuste de cero y luego revisar el intervalo de nuevo cuando el posicionador 3582 esté calibrado correctamente, podemos estar seguros de que cuando la señal de entrada está en los límites; en este caso, tres y quince PSI sabemos que la válvula está bien abierta o en el asiento con una fuerza total del actuador, una vez que el cero y el intervalo se ajustan correctamente, no olvide apretar todas las tuercas de seguridad , por lo que podemos c calibrar el posicionador 3582 en solo seis pasos,

VERY NICE VIDEO...😍 wished i had this back in 1970 when the learning class was going on with just a book... thanks...👏

[@Bataviaish]

Do you have video about calibration Control Valve with pneumatic controler, I want see it...thank's

[@ducbinhhdu]

Please make a video about Calibrating a Fisher C1 Positioner, thanks!

[@AashishBharat]

Do we lock the two screws on the flapper assembly? The calibration goes out when I do

[@kevin3818]

I have a fisher Valve/Positioner, having issues. Note all was operating properly and now the valve isn't following commands. It is a chilled water valve/actuator/positioner. Supply air is 25psi, the control air is 8-14psi full close to full open. At this point, with supply air the valve is full open regardless of control air *nc 8psi*. It is a 1/3 2/3 valve set up. Both fisher valves actuator positioners.

[@yourebreathingmanuallynow3944]

Was the issue resolved? I am curious about what was the problem. If it is not moving at all I am guessing shaft arm is disconnected or if it has wrong movement despite calibration maybe it is the beam alignment.

[@VictorThomas26]

Thanks for the video, but I have a normally closed valve, should the positioner be calibrated the same way?

[@FisherControlValve]

The video shows an air to Close control valve or you would say a normally Open valve. The calibration procedure is the same. At 0% input, the 3582 output is also zero, thus valve stays Closed. This adjustment is done by the nozzle. Slowly increase the Input, and watch when the output increases. The input signal should be about 3.5 psi or lower. Follow the video procedure to the 100% input signal and adj the span. Repeat the zero and span adj to ensure it is correctly adjusted.

[@dhaivatbuch5704]

Make a video on strock calibration

[@jeremykapofi846]

how do i calibrate that same valve if all 3 gauges are not working?

[@londonboy9422]

Can you not just replace the gauges?

[@cijj84]

replace the gauges or use your calibrated gauge to set it up and remove when your done. No way to calibrate with out knowing the pressure

[@intellectracoon]

thanks a lot this is very informative.

[@alisubahan2370]

Suwun yoo mbah :D

[@alimahamud9314]

thanks boss how much air we use

[@irfanahmad-ey7yi]

20psi

[@MM-vi9kh]

Is 3-15 standard for all valves or it depends on valve size?

[@codypendency9482]

Depends on the size different valves have different bench sets it will say on the valves information plate

[@Ali_SRC279]

There is 6-30 psi it depends on the size of actuater

[@cijj84]

usually in a 1-5 ratio unless its some really odd setup. Just like your 4-20mA single is a 1-5 ratio used on your I/P to make your 3-15psi single air
