Looking for a good solution for measuring the volume of overflow from a number of good old duplex lift stations. Each station has a concrete overflow pipe, probably between 8 and 12 inches. There are a lot of ideas kicking around like using the already measured analog wet well level to know...
I am replacing a 30+ year old proprietary control board on a sewage vacuum tank system. I am installing a PLC with 24v DC inputs. The system is basically a big steel tank with 5 probes (see photo) shoved in the side and insulated from the tank. I need to have a dry contact for each of 4...
Hi: I am looking to retrofit a machine that has a hydraulic pump, providing tension and speed on some driven wheels. There is presently an old stand-alone closed loop control board controlling the pump swivel angle by positioning the spool on a proportional valve. Feedback to the card...
Looking for interpretation of the attached drawing. Power source is 2-wire, single phase. Wondering if the pump motor is 3-phase (hence the 3 wires going to the motor) using the capacitors for start and run phase shifting, or ??
Trying to calibrate temperature probes using our usual expensive Fluke calibrator. The sensors are 100ohm platinum RTD probes with S-products 82800 transmitter pucks. We have the software and cable from S-products to connect a PC to the transmitter, but when we "inject" various temperature...
I am replacing the control system on an industrial ammonia refrigeration system. The old system displayed a "superheat" value in degrees K. I don't have access to the code that calculated this superheat value. I have looked at the T/P charts, but I am still not sure what to calculate for...
I have access to the wiring from 2 different heat trace cable sets. The wires I have access to are not the actual ends of the heating cables. They are obviously spliced between the heating cable and the junction box I have access to. I read 156 ohms on one set of wires and 95 ohms on the...
I have a couple older Siemens voltage regulators model AS60-1A. I am looking for information on testing these devices. I cannot locate a manual for these. They have 14 connections and two 12 position rotary dial switches. Each dial switch has a small pot on it. The terminals are marked 1...
Looking for "direct" replacements for Siemens Voltage Regulator KS60-1A. I suspect these are obsolete, and I am hoping there is a direct replacement. I believe these are often used on generating equipment. Thanks!
I have a 115v 3/4 HP winch motor that I need to power at a remote site where there is only 575v 3 phase. I can add a transformer to that location to give me the 115v. Question is....what size (kVA) and what amps for the time delay fuses? FLA on the winch is 13.6. Thanks!
I am working on a system that has 407 MHz system that has a Dataradio and Omni antenna on each end. The sites are about .6 miles apart, with no obstructions between. Just starting to investigate communication problems. Would a Yagi be a better choice for one of the stations, or should the...
I'm a newbie with the Motorola ACE3600 and have an issue with data retention. These RTUs have a battery backup but if the AC is down long enough for the battery to discharge fully, as far as I can see...all data is lost. The CPU lithium battery maintains the program code, but none of the data...
Modiccn Compact DAU-204 Analog Output card configured for 4-20mA. Everything is configured correctly (switches and software), but the outputs are acting weird. Raw value is 0-4095 which should correspond to 4-20mA but the output signal (on at least 2 of the channels (didn't test the other 2))...
I have a WIndows 2000 system that automatically produces a report on a local (default) printer, once a day. I would like to change this to print 800 feet from the PC. I can run ethernet cable indoors for about 200 of the 800 feet but the rest of the distance is outdoors (to another building)...
Does anyone have a spec on how many operations a typical on/off-spring return damper control motor should be able to perform in it lifetime. This is assuming normal loading, and normal operating conditions. This particluar unit is a Belimo NF120. I have an application where the damper is...
I have a 60 HP air compressor with air intake and exhaust to outside. Both ducts have electrical dampers that open when the compressor runs. Problem is...the outdoor air is too cold in the winter and the filters, etc are freezing. Considering putting in a bypass duct, damper, and temperature...
It's been a number of years since I put together a radio (line-of-sight) SCADA system and I'm sure technology has made some great advances. I'm looking to install a system on a site about a mile square, with good line-of-sight possibilities for communications. There will be 6-8 remote...
Tons of experience with older PVs and Panelbuilder32 software. Now...need to program a PV400 going on a CompactLogix system. Need to know (1) how to set up comms for the download (PV doesn't show up in Linx and can't find where to assign IP address if necessary), and (2) how to import the tags...
I know I have this somewhere but can't find it. I have a .75 Eurodrive gearmotor with the "really common" brake on it. Unfortunatley I can't find any numbers on it. It is the brake that has the manual release setscrew and lever, and is adjusted by measuring the gap with the brake released...
