I'm trying to retrofit an existing fire sprinkler system in a storage warehouse that will be storing mostly motor, transmission and hydraulic oil in 5 gallon plastic containers. The maximum storage height is 16'-6' and the ceiling height is 20'-6". I'm following NFPA 30 for the design criteria...
Hi,
I'm working on a project where I will need to switch a 24 volt coil voltage relay with a 1.5-2.0V signal. I've read on some threads that you can use a transistor to do this.
Does anyone know the details of this?
Any help will be appreciated. Thanks,
Hi,
I have a Amura-Seiki vertical machining center that the spindle stalls unexpectedly but the feed does not stop. This happens while the spindle/cutter is approaching the part to cut. It does not happen for every cycle. it happens intermitently. The machine can run for hours without this...

We are currently using a bubbler type DP system to measure the level. This transmitters sends a signal to the computer which in turns controls a feed valve to add acid as required. Due to all the vapor created, the pressure on the upper portion of hte tank keeps changing constantly...
Hi,
I'm looking for some help in finding a better way of measuring the level of an acid recovery tank. the tank is used to separate impurities from Hydrochloric Acid. The "contaminated" acid is heated to 235 F and the surface starts foaming and releasing vapors which affect the use of...
We have a Viper vertical mill with a fanuc 18-M control. one of our maintenance guys replaced the memory back up battery from the axis drives and all home parameters were lost. We need to re-set these parameters but we do not know how.
Any instructions on how to do this will be appreciated...
I'm monitoring power consumption on an electrically heated furnace. I'm logging the kW with a data logger. The kW readings/samples are each second. How do I estimate the kW usage per hour based on the readings of kW I get per second? Do I add up all the kW in one hour period?
Thanks,
MJCronin,
Are you referring to a stand pipe to avoid turbulence? We've tried a stand pipe but the acid produces so many vapors that need to be released from the pipe and most of the meters either don't resist the acid and the ultrasonic transmitters don't work well with the vapor. may be a...
Hi,
I'm struggling to control the level on a hydrochloric acid tank that is part of an acid recovery system. The problem is controlling the level of the acid. The contaminated acid is heated to 236 F and is boiling. This creates turbulence, foaming and vapors. We are currently using a...
Thank you all for your help. I already got a quote from Prosoft for a Modbus communication module since I already have a Modbus module on the Yokowaga side.
Hi,
I'm trying to share data from an AB SLC 5/05 PLC to a Yokowaga Centum CS3000 DCS system and I'm not sure what would be the best way of doing this. what are all the possible ways that an AB SLC 500 can communicate? Is Ethernet IP the only one that it supports?.
Any suggestions would be...
MikeHalloran,
We're actually evacuating hot gas from a cvd reactor. I'm looking into reducing the amount of oil waste generated. I want to compare the rate of degradation of both oils and ultimately increase the oil change intervals in order to generate less waste. I need to determine if by...
What are the advantages of using a synthetic oil on oil sealed vacuum pump applications vs using a regular solvent-based refined oils. Does it last longer? What are the disadvantages? Is it only the price.
Please help.
NWBeaver,
Thank you for your reply, It is a stand alone system. This press is for use on our R&D department. This is why we don't want to spend too much money on this project. How difficult is it to program PanelView to be able to access this PID loop instructions?

These 2 loops are part of a recipe. The temperature loop and pressure loops should be started simultaneously. This should be done on a single "cycle start" switch. I'm trying to prevent the operator from forgetting to start either one of the loops. This is why I'm trying to use an HMI...
Hi everyone,
I was given the task of automating an oil heated press operation. The hot press needs two PID loops one to control the temperature and one to control the pressure. I have programmed the SLC 5/03 PLC before but only to control discrete outputs to open/close valves, alarms etc...
Does any one know what RGMS stands for? I see it called out on a couple of drawings as the required material for a shaft but I can't find any data on it.
Any help will be appreciated
