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...
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,
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...
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...
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.
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
