When troubleshooting a faulty electric motor, time (or in this case downtime) is money. This notion was drilled into my head in my early years and has proven itself over and over again. Isolating the problem in the shortest amount of time saves costly downtime (and maybe even your job). The other point that has been permanently burned into my consciousness involves a different type of self-preservation: always control the electrical circuit you are troubleshooting by following proper lock-out/tag-out procedures. Observing safe maintenance procedures must always be given proper attention. For these reasons, it is imperative that the maintenance electrician, technician or engineer uses a troubleshooting methodology that enables them to isolate the problem in the shortest amount of time. Still, the logical process of elimination used to identify the root cause of an ac motor's malfunctioning can differ.

Troubleshooting Manual For Motor Rewinding Machine

At times it is more effective to start at the motor and work back to the starter; in other instances it's better to begin at the starter and move towards the motor. My general preference is to begin at the excitation source and work towards the motor. For the purpose of this article, I'm addressing typical starting problems only. Running problems can be numerous and varied, and in many cases can be traced all the way back to improper motor specification for a particular application. Starting problems with three-phase ac inductive motors can be grouped into three primary categories: voltage source problems; motor excitation problems, which include the motor starter and ac drive; and application or mechanical problems.

Troubleshooting voltage source problems Use a process of elimination to isolate and diagnose voltage source problems. Refer to 'Voltage source problems flowchart' on page 66, which illustrates the steps of the following troubleshooting procedure:. Check the incoming power to the motor starter. Using a digital multimeter (DMM) set to voltage mode, verify that all three phases of electrical potential are present. If one or more of the phases is missing, disconnect the primary voltage source (incoming power disconnect switch) and replace the incoming power fuses or reset the motor-control circuit breaker. Prior to restoring the primary voltage source, set the DMM to continuity mode (ohms) and verify at the motor starter line contactors that there is not a phase-to-phase short or a phase-to-ground short. If there is a short or ground on the line side of the starter, replace the starter contactor and verify that the short or ground is now clear.

Next, verify that the load side of the circuit does not have a phase-to-phase short or a phase-to-ground short. This final continuity check will also verify that the motor line does not have an open phase. If the motor starter line circuits are clear, the problem is on the load side of the starter. Follow the circuit to the load side of the starter. Try to reset each of the motor thermal overloads on the motor starter. If any one of the overloads have tripped you will be able to feel when the overload resets while pressing the reset pushbutton.

If you completed the continuity check of the load side of the motor contactor described in Step 2 and the circuits are clear, restore the incoming power and start the motor. If the continuity check on the load side of the contactor is shorted phase-to-phase, phase-to-ground or open phase-to-phase, then follow the power circuit to the motor. Disconnect the incoming motor leads at the ac motor electrical conduit box. Check the motor starter leads for a phase-to-phase or a phase-to-ground short. If either of these two problems exists, check the motor lead wiring. If the motor starter leads are clear, move on to the motor.

With the motor still disconnected, check the motor leads for a phase-to-phase or a phase-to-ground short. There is a high probability that if there were no problems found previously in the circuit, the motor has a phase-to-phase short or a short-to-ground fault. If you have verified a phase-to-phase or phase-to-ground fault in the motor, replace the motor and start the system. If there appears to be no problem with the ac motor or its power circuit, then test the motor insulation with an insulation tester. The insulation test determines if the motor windings are 'breaking down' during running conditions. If the insulation test results are negative, a mechanical problem is probably causing the motor overload. Uncouple the motor from the mechanical load and start the motor.

For

If the motor runs, the problem is in the mechanical drive train. If the motor does not run and the motor overloads trip again, the problem is in the motor bearings. Troubleshooting control circuit problems. You can also use a process of elimination to isolate and diagnose control circuit problems. Refer to 'Control circuit problems flowchart' on page 68, which illustrates the steps of the following troubleshooting procedure:. If all three phases of electrical voltage were present when you performed Step 1 of 'Troubleshooting voltage source problems,' then the motor starter overload and control circuits should be checked.

Determine if all or any of the motor starter overloads are tripped by pressing the motor overload reset pushbutton. If the motor overload(s) were tripped, try to restart the motor. If the problem was isolated to the motor overload(s), the motor should run. If the motor overload(s) trips again, return to Step 5 of 'Troubleshooting voltage source problems' to determine if the problem is a motor problem or load problem. If the motor overloads are not tripped, verify that the starter control circuit has the proper secondary voltage using a DMM set to voltage mode and the appropriate range.

If the proper voltage is not present, disconnect the motor starter's incoming power supply. Using the DMM in continuity mode (Ohms), verify the integrity of the control voltage transformer fuse. Replace the fuse if blown, and. identify the motor starter control circuit problem.

If the starter control transformer fuse is good, proceed to Step 8 of this troubleshooting procedure. Disconnect the motor starter contactor coil and check for a short, ground or open circuit. If a short or ground is found, replace the motor starter contactor coil and start the motor. If the motor start contactor coil is good, with the coil still disconnected, check the control circuit wiring to the contactor coil.

Small Electric Motor Rewinding Services

If a short or ground is detected, disconnect the field wiring circuit to the motor starter to determine if the problem is internal to the motor contactor overload circuit(s) or in the field control wiring. If an electrical ground is located in the motor starter overloads circuit, replace the motor overload(s). Once the failed motor overloads have been replaced verify circuit continuity, reconnect the starter coil and control field wiring, restore incoming power and start the motor. If an electrical ground is not located in the motor starter overload circuit, the problem has been isolated to the control circuit field wiring.

Clear the ground in the field wiring circuit. Then reconnect the motor starter coil, overload circuit and field wiring, restore incoming power and start the motor. If you determine that the starter control voltage is intact and present, suspect a potential open circuit in the motor overloads or control circuit. To check for an open circuit, first disconnect the incoming power supply, and using the DMM in continuity mode (Ohms), verify the circuit integrity of the motor overloads control circuit (secondary contacts). If the motor overloads control circuit is good (all NC contacts have continuity), then the field control circuit to the motor starter is the problem. To troubleshoot the field control circuit to the motor starter, check continuity across the device that supplies the start signal to the motor starter, which could be a PLC contact closure, relay contact closure or start/stop pushbutton circuit. After the control circuit problem has been located and corrected, restore the incoming power and start the motor.

AC drive excitation — drive faults. When a drive fault occurs in an ac drive and motor application, determine if the fault is a motor, drive or application problem. The diagnostic technology offered in modern ac drives can help you troubleshoot many drive problems. Manufacturers often include internal diagnostic capabilities in the drive's microprocessor control. By using these drive fault diagnostics, you can easily determine and remedy the fault.

Some of the most common problems related to integrating an ac drive with an ac motor are listed in the table 'Typical ac drive faults.' However, there are may other possible drive faults associated with motor/drive tuning, application requirements, communication errors, external device errors and initial programming errors.

If you are still unable to locate the source of the trouble after ruling out the causes listed in the table, contact the equipment manufacturer or your local distributor for further diagnostic assistance. The majority of ac motor and drive problems can be solved by using the drive manufacturer's manual. Each drive fault that is monitored and annunciated by the drive's microprocessor is listed in the troubleshooting section of the manual. If you cannot locate your manual, contact your local manufacturer's representative or refer to the manufacturer's website to download a copy. AC motor and drive technology The application of ac motor and ac drive technology is becoming much more prevalent in applications that were previously done with dc technology (variable speed applications) or across-the-line starters (historically constant speed applications used on fans and pumps). With the development of different ac drive technologies, such as soft start, V/Hz, open loop vector and closed loop vector drives, this trend will likely continue — and if anything, increase. The ability to apply the right ac motor technology in the right application ensures that the motor/excitation technology used will provide trouble-free operation for many years.

The ability to develop and execute a logical troubleshooting methodology when equipment failure does occur will assure that your process achieves the maximum amount of uptime.

You can buy them very cheaply at most computer shops, then you don't have to use the stickers if your keyboard only has the 'western' Keytops. RDN Edit: For sure a Thai keyboard is easy to get and install, but I think you meant to post this on the original thread?

Anyway, I too have a USB Thai keyboard - 'Genius brand, model KU-0138'. But I also have an external hard drive connected to my lap-top's only USB port, and it doesn't work too well sharing the port with another device. Hence, in the other topic, I talked about the 'On-Screen Keyboard'. For short periods, it's OK - you just see a normal keyboard until you switch language using the Language Bar. Then the keys change to the Kedmanee keyboard and - using the mouse - you can type in Thai.

But if I want to do a lot of typing, I will plug in the USB keyboard. I will add information later about keyboards to the pinned first post above.

I usually click in an 'edit' box in this forum web or in 'Notepad' before attempting to change the input language. Have you read the topic about the 'Microsoft Visual Keyboard'. You can get it from here: I use it now in preference to the 'on-screen keyboard' that comes with XP as it can be made large and so is much easier to read - especially the Thai fonts on the keys. This program was actually written for operating systems other than XP because they did not have an 'on-screen keyboard'. But the guys who wrote this program obviously learned about some of the failings of the 'on-screen keyboard' and made it better! I can produce ๆไไำพะััีรรนรย., as though some one were just tapping keys from left to right along the second row and producing an arbitrary string of Thai characters. The problem seems to be that your browser thinks it is reasonable to send the text you entered in the encoding of the page, so it sends 8-bit codes.

At the receiving end, the server is probably expecting Latin-1, so that is how they are interpreted. Mishap - your message can then only be read if the Thaivisa page is switched to a Thai encoding. With IE or Firefox on Windows XP, I just leave the encoding unchanged and type with the keyboard set to Thai or English as I desire, and it works fine. Cutting and pasting to here from other web pages in a Thai encoding also work fine. The same goes for Windows 2000 and IE, except I don't have the facility to type in Thai on that Windows 2000 system - I have to type the Thai in a special program and then cut and paste.

As you type the message into the editing box, it should be stored as 16-bit Unicode codes. I recommend that you try to type in Thai without changing the encoding of the web page - leave it as Latin-1/Western European.

When i opened a word document and typed i just got a series of blank squares for every character typed. Is there something i have done wrong? If you are using Word X, it is obsolete and can't do Unicode scripts like Thai. Aside from AppleWorks, any other word processor should work ok. If you are using Word 2004 and higher, make sure you have it set to a font that includes Thai, like Lucida Grande, Thonburi, Ayuthaya, Silom, Krungthep.

Epanet Software For Mac

US EPA EPANET Introduction EPANET is a Windows 95/98/NT program that performs extended period simulation of hydraulic and water-quality behavior within pressurized pipe networks. A network can consist of pipes, nodes (pipe junctions), pumps, valves and storage tanks or reservoirs. EPANET tracks the flow of water in each pipe, the pressure at each node, the height of water in each tank, and the concentration of a chemical species throughout the network during a simulation period comprised of multiple time steps. In addition to chemical species, water age and source tracing can also be simulated.

EPANET was developed by the Water Supply and Water Resources Division (formerly the Drinking Water Research Division) of the U.S. Environmental Protection Agency's National Risk Management Research Laboratory. It is public domain software that may be freely copied and distributed. EPANET provides a fully-equipped, extended period hydraulic analysis package which can:. handle systems of any size. compute friction head loss using the Hazen-Williams, Darcy-Weisbach, or Chezy-Manning formulas. include minor head losses for bends, fittings, etc.

EPA SWMM 5 for Mac OS X. The EPA SWMM (Storm Water Management Model) is an app that can be used to design and analyse sewage networks. EPA provides a Windows version of the program as well as the source code.

allow storage tanks to have any shape (i.e., diameter can vary with height). consider multiple demand categories at nodes, each with its own pattern of time variation. model pressure-dependent flow issuing from emitters (sprinkler heads).

base system operation on simple tank level or timer controls as well as on complex rule-based controls. EPANET was specifically developed to help water utilities maintain and improve the quality of water delivered to consumers through their distribution systems.

It can be used to design sampling programs, study disinfectant loss and by-product formation, and conduct consumer exposure assessments. It can assist in evaluating alternative strategies for improving water quality such as altering source utilization within multi-source systems, modifying pumping and tank filling/emptying schedules to reduce water age, utilizing booster disinfection stations at key locations to maintain target residuals, and planning a cost-effective program of targeted pipe cleaning and replacement. EPANET can also be used to plan and improve a system's hydraulic performance. Pipe, pump and valve placement and sizing, energy minimization, fire flow analysis, vulnerability studies, and operator training are just some of the activities that EPANET can assist with.

The HWS provides various features including internet absentee bidding, internet-only auctions, and webcast auctions. The HWS is able to changes its appearance to coincide with the website that it is powering. Accordingly, the HWS powers the www.hibid.com website as well as numerous Auction Flex customer websites. This ability to change appearance is a feature of the HWS.

Much like internet merchant account providers can host a secure web page for a vendor to easily process payments, the HWS hosts certain portions of the auctioneer's website to easily enable advanced features such as internet bidding. INTERNET ABSENTEE BIDDING Internet absentee bidding allows you to place a bid for an item in advance of an auction. This allows you to place bids on lots without actually attending the auction. INTERNET-ONLY AUCTIONS Internet only bidding allows you to place a bid for an item prior to the auction lot closing online. In an internet-only auction there is no live auction. WEBCAST AUCTIONS Webcast auctions allow you to bid in real-time against other bidders or place pre-bids prior to a lot going 'live'. Lots are sold in accordance with the Auctioneer's terms and conditions which are accessible from each lot's page.

It is your responsibility to read and accept the Auctioneer's terms and conditions prior to placing your bid. When you place a bid you are agreeing to be bound by the Auctioneer's & Sebae's terms and conditions. By placing a bid you are entering into a legally binding and enforceable contract.

Sebae may, in its entire discretion, refuse or remove bids where it suspects that bids contravene this prohibition. By placing a bid, you are making a binding and irrevocable offer to purchase the Item at any price up to the maximum bid amount you submit. If you win, you must complete the transaction, subject to any contractual right or other right at law to rescind the contract in certain circumstances. Failure to complete transaction without lawful reason is not only a breach of your contract with the Seller but also a breach of this User Agreement. The amount bid can be increased but cannot be decreased.

The auctioneer may, at their discretion, allow you to withdraw and resubmit a bid in the case of bids containing an obvious typographical error. You may forward a request to withdraw a bid and resubmit a correct bid by immediately sending an email to the auctioneer, however, there is no guarantee that any bid will be withdrawn.

NOTICE OF END OF SALE, PAYMENT & SHIPPING After the sale has ended, the auctioneer will notify the winning bidder via phone, fax or mail that they have won.

The Cell The cell is possibly the most important concept in biology since it is the basic unit of life. Every living organism is made up of cells (or just one in the case of bacteria). Your body is composed of microsopic cells that are only visible if viewed under a microsocope. All the animals, trees and plants are made up of cells that share many similar characteristics. They all have s separating them from the outside environment, DNA to store information, RNA to pass this information to the ribosome- and ultimately protein that is translated from the RNA. The, or plasma membrane separates the cell from exterior environment and is composed of a phospholipid bilayer. It is composed of phospholipids which each have a polar (hydrophillic) head and a polar (hydrophobic tail).

The polarity of the phospholipids helps them self assemble into a structure where the hydrophobic tails all face inward away from the aqueous interior and exterior of the cell. Cell membrane' title='The Phospholipids of the Cell Membrane' The is embeded with proteins. Transmembrane proteins pass all the way through the membrane, while peripheral proteins only pass through one side of the bilayer. Transmembrane proteins are often are involved in the transport of compounds and nutritents across the lipid bilayer since only small hydrophobic molecules, water and gas can diffuse freely through the hydrophobic interior.

Organelles of the Cell Eukaryotic cells (all organisms except bacteria and archaea (prokaryotes)) have complex organelles which are surrouned by their own membrane (similar to the ). Nucleus - the nucleus is where DNA is stored and where RNA transcription occurs. Each cell has one nucleus. Within the nucleus is a structure called the nucleolus which is the site of ribosome assembly. The image below is an image of a cell with the nucleus stained blue and the multiple mitochondria stained red Mitochondria - often refered to as the 'powerhouse' of the cell, this is the organelle that generates ATP (the energy currency of the cell).

Mitochondria have a highly folded inner membrane that provides surface area for the enzymatic reactions that produce ATP. The interior of the two membranes is called the matrix, the space in between the two membranes is called the intermembrane space and the folds created by the inner membrane are called cristae. Mitochondria also contain their own DNA which encodes some of the enzymes that are used inside the mitochondria. Endoplasmic reticulum - the system of membranes used for the folding and transport of proteins.

Rough ER (endoplasmic reticulum) is covered by ribosomes while Smooth ER is not. Ribosomes are structures made of protein and rRNA (ribosomal RNA) where proteins are made (translated). Golgi apparatus - used for modifying and packaging of proteins Chloroplast - in plants this organelle is responsible for the reactions of photosynthesis Cell Parts There are other important components of the cell that are not considered organelles since they are not surrounded by their own lipid bilayer. Ribosomes - the ribosome is a large complex made of RNA and protein that translates mRNA into protein. Lysosomes - where the breakdown of nutrients can occur using enzymes Cell Membrane - this is the structure composed of a lipid bilayer that separates the cell from the outside environment Cell Wall - found only in plant and bacteria this structure is found outside the and serves as a more rigid protective barrier Differences Between Eukaryotes and Prokaryotes Bacteria (and archaea which are seldomly mentioned) are prokaryotes. The term prokaryotes is derived from pro (before) and karya (nucleus): before-nucleus = pro-karya = prokaryote. This is because it is thought that bacteria are still very similar to their primitive ancestors which did not have a nucleus.

So- bacteria (prokaryotes) do not have a nucleus, while all eukaryotic cells do have a nucleus (this is a popular question for exams- and a common mistake). Bacteria also lack all other membrane bound organelles. Bacteria do not have: organelles nucleus mitochondria endoplasmic reticulum golgi appartus chloroplast lysosomes Bacteria do have: ribosomes cell wall (which eukaryotes don't have) Its also important to remember that while bacteria don't have a nucleus they definitely still have DNA organized in a chromosome that is transcribed to mRNA and then translated to protein on a ribosome.
