If you look in the manual for the temperature device, you will find that it has a range of 0-5000 counts = 0-100 C or a range that is in the same ratio. This gives a reasonable resolution to the temperature measurement but means that the HMI, PLC or DCS reading this value needs to apply a...

A Google search finds that Hamworthy Combustion is now part of John Zink. https://www.johnzinkhamworthy.com/products-applications/burners/ So try them for replacement parts. Your burners are Hamsworthy but are your flame scanners? We had B&W boilers and burners for our Utility Boilers...

Provide your email address and I will send you a link to a dropbox folder where you can upload the wiring diagram. >I have a wiring diagram for the existing sensor I can email >to anyone if they can help.

What is the part number or info on any label on the pressure transducer? Can you determine the transducer output electrical range from the digital indicator? Any info or part number? If the Tx has 4 wires and a 5 VDC supply then the output could be 1-5 VDC, 0-5 VDC, 0-20 mA or 4-20 mA...

If the process impacts, the safety impacts, equipment damage and the production loss impacts from a false trip or a failure to trip are low enough then it's OK. If impacts are high as determined by a HAZOP then using a 2oo3 transmitter arrangement is recommended. 3 transmitters with...

Looks like you need software from the manufacturer: SAGE ADDRESSER SOFTWARE "Addresser is a convenient software kit that includes Addresser software, as well as an optically isolated ULINX RS485 to USB converter. The Addresser is a READ/WRITE Program with drop-down menus for convenient user...

Do you have working oil reservoir heaters in your control oil system? What is the operating temperature and what is the heater temperature switch set to? There is a minimum operating oil temperature so that cold weather should not be a factor and water in oil is minimized by eliminating...

I think you are double dipping on your historian data. The Experion servers already get alarms, events and history. So instead of loading down the C300 with Expersion server requests and your historian requests, have your historian get the data from the Experian server. This is what our OSI...

The control action has nothing to do with the action of the control valve. If the process variable (PV) is below SP and increasing, or not, you still want to increase temperature, so with a negative error you require reverse control action. So not about increasing or decreasing PV, but about...

There are 2 direction parameters for a control loop: 1- Control Action - Direct or Reverse 2- Output Action - Direct or Reverse Since when PV is above SP, positive error, you want the loop to reduce fuel flow, the control action is reverse. Since the control valve will open with...

You have choosen a 4-20mA transmitter that outputs 4-20mA over a range of DAC counts from 670 to 3460. What you need is their 4-20mA receiver that will take a 4-20mA input and provide a DAC count...

Just the Experion part of Knowledge Builder would not be that large. But... You can Google search for the Experion version and info you want, it may be online for download. Or sign up for a free user account with Honeywell Automation, they have all the manuals online available for download...

I think that a Y fitting will tend to create a suction at the scanner end of the fitting, doing a better job keeping the scanner clean than a tee. Do you have 2 scanner air blowers? Does switching between them make a difference? Is one of them weak? What happens when you run both? good luck

Short answer no. Pnuematic field transmitters and controllers used to be the standard. They are now obsolete, uncommon and if still available very expensive. Electronic smart transmitters either 4-20mA HART or fieldbus are now the standard. Pneumatic air power for valves is still the...

Do that mean there are other spare TCP ports on the CCM321 comm card? I would add an Ethernet switch to expand that Ethernet connection and use a Modbus 485 to Ethernet converter to add the gas controller to the network. good luck

The 3503E 24VDC/VAC input module has self testing. Are these real logic transitions that affect logic and cause trips? What do the card diagnostics and events show? In Tristation control panel, check your actual system scan time and what the free or spare system scan time is. I have seen...

2C for each DI and DO. I do not know your working voltages (I/O or MOV), cable lengths, cable gauge or circuit loads, but if the MOV has some internal commons you may be able to reduce wire count to 3C for 2 DI and 3C for 2 DO. You will have to consider I/O voltage vs MOV control voltage...

Since both the DI and DO are control signals they can be in the same cable if the voltages are the same. So you could use 8C cable from the marshaling to the field or a larger home run cable from marshaling to a local JB then a 8C cable to the MOV. good luck

It depends what you are trying to do, and what the functionality and logic required is. There are atleast 2 ways to do it. 1-via SCADA tags, you setup a controller, channel and points in SCADA to access the PLC. SCADA is good for indication, alarms, operator commands and feedback. 2-If...
