Question 1

How do I connect / wire a contactor and overload to create a Direct On Line (DOL) Starter?

Accepted Answer

Attached is a .pdf file with pictorial diagrams (1) of how you would connect the four most common variants of a DOL starter.They show diagrams for 240 and 415 VAC control. The most common for small Direct On-Line Starters (DOLs) is 415VAC, as this requires no neutral to be fed to the starter.Options are also given for using either a remote stop switch or for using the stop button which is integral with the overload. In the latter case the stop button is not a switch, it is a plunger type device fitted into the lid/door of the enclosure, which will physically press the overload stop. This is the method that is used in the Schneider Electric TeSys enclosed motor starters, such as the TeSys LE range.Remote and Emergency stops(2) are shown fitted between terminals A2 and 96, though they can also be fitted between 14 and 95, or even both if multiple stops are involved.WarningParticular care must be taken to accurately fit the stop button when using the plunger type stop without any additional remote stop, as if for any reason the plunger does not activate the stop button on the overload, there will be no way of stopping the motor without disconnecting the supply.NOTES:(1) These drawings are functional schematics. It remains the responsibility of the installer to ensure that the requirements of local directives and legislation are met and that appropriate circuit protection is provided.(2) Inclusion of E stops in these circuits is purely for illustrative purposes and may be acceptable in simple relatively low risk safety systems. However, depending on the risk assessment carried out on the plant it may not be appropriate, other Emergency Stop facilities may be necessary, particularly in high risk applications. Consult you safety consultant.NOTE regarding Terminal NumberingThe circuits are based upon TeSys D range contactors and overloads. Terminal numbering is to a common standard so most other contactors can be wired similarly. However, be aware that there are contactors that use different numbering systems.NOTE if using TeSys KThe TeSys LR2K overloads (LR2K****) for use with TeSys K range contactors (LC1K****) have additional pins on their overloads to make direct connection to terminals 14 on contactor to 95 on overload and A2 on contactor to 96 on overload. The diagrams provided in the attached PDF file do not relate to such TeSys K systems unless the 2 right hand pins are first removed. These pins are specially weakened for this purpose and may easily be snapped off by bending backwards with a pair of pliers as shown for one pin on the diagram belowHowever, doing this is just making extra work. It is better to wire in accordance with the K Series diagram.

Question 2

What are the separate parts required to build up star delta starters for motors 7.5kW through to 132kW suitable for mounting on DIN rail?

Accepted Answer

The table below indicates the selection of the power switching components necessary to build up a star delta starters, with mechanical interlocks between star and delta contactors, suitable for mounting on DIN rail in a suitable control panel.Notes: In some cases, the starter can be supplied assembled (prefix LC3) with the overload relay supplied separately. These should be checked on a case-by-case basis, as some are obsolete.Overload selection is based on the motor full load current (FLC) x 0.58 due to the mounting position in the 'delta loop'.In the case of 110 and 132 kW there is a requirement for a separate control relay and timer to ensure sufficient delay in the changeover time from star to delta contactor.

Question 3

What are the causes SCF1 Short circuit fault on an Altivar ATV320 variable speed drive?

Accepted Answer

Issue:Getting SCF1 fault on an ATV320.Product Line:Altivar 320Environment:AllCause:Motor short circuitResolution:SCF1 is a short-circuit event.Except for a real short circuit event at the Alivar drive output (motor, motor cables) , the SCF1 can have another reason:- high magnetizing current (motor saturated),- low motor inductance (real vs measured),- lack of symmetry in the motor circuit,- motor cabling issue, or- the motor itself.The best way is to record scope (fast scope) with variables LCR (motor current, filtered), SLCR (motor current, non-filtered), RFR (motor speed) to see the moment when SCF1 occurs. Auto-tuning data can affect the occurrence of SCF1.Try to lower LFA parameter a little and record the same Somove scope again (fast scope, sampling time 10 ms or faster if it reveals any anomalies) . Compare the results at different LFA. It is recommended to apply the same load cycle to find relevant comparisons.Also, Check if the magnetizing current IDA measured by the Altivar corresponds to a reasonable value. (In * sqrt (1-(cos phi)^2)Try different motor control laws.Change switching frequency, sometimes it helps when increasing SFR, sometimes when decreasing.Think about adding a motor choke as this choke can reduce ripples in motor current and so higher probability that SCF1 threshold will not be exceeded.For those that cannot find IDA, LFA parameters, or do not have manuals, a picture from Somove in the attachment

Question 4

How to give an address to variables that are part of an structure in EcoStruxure Machine Expert?

Accepted Answer

Issue: This FAQ provides an alternative for assigning addresses to variables that are part of a structure in EcoStruxure Machine Expert, as this process is not intuitive. Additionally, this FAQ includes an example illustrating the relationship between different memory types (e.g., %MLx, %MBx, %MWx, %MDx, %MXx). This information is useful when using the Modbus TCP protocol to read tags from an M241, M251, or M262 controller and share them with another device (e.g., SCADA, HMI, PLC). Product: EcoStruxure Machine Expert (previously SoMachine) Environment: PLC Configuration Software in Windows Resolution: When using Modbus TCP, you must assign an address to the variables. If you are working with structures, follow the steps below: a. Create a structure and calculate its size in bytes. b. In Machine Expert, use %MLx to address structures. This memory type occupies 8 bytes. Depending on the structure size, you must leave enough space between instances to avoid overlap (unfortunately, this must be done manually). In this example: %ML0 starts at %MB0 (Memory Byte).%ML3 starts at %MB24. This spacing ensures all tags fit properly. c. Create a tag for each element of the structure instance and assign an address using %MWx (INT/WORD), %MXx (BOOL/Bit), or %MDx (REAL), depending on the data type. d. Validation. In this example: a. Structure GateOC is create that consist of 17 bytes. Note: 6 INT (2 bytes each) + 2 BOOL (1 bit each, so 1 byte is required) + 1 REAL (4 bytes) = 17 bytes b. Create each structure instance and assign it a %MLx address, leaving enough space to prevent overlapping. c. Create a set of tags for each instance, in the picture below a set of tags was created for instance CokRecLg1TpGt. Note: Not all tags use %MWx, but the comments show the relationship between %MXx and %MDx with the %MWx memory type. d. Validation. Each color represents a different case, and in the end, everything aligns. Yellow is consistent across all three representations, as are sky blue and purple. For the REAL tag: WORD 1 = 33,554 (lower 16 bits) WORD 2 = 16,288 (upper 16 bits) REAL ≈ 1.254 Unfortunately, this is the only way to assign addresses to tags inside a structure in Machine Expert. It is a manual process, and you must maintain proper order to ensure tags do not overlap

Question 6

What is Eddy Current and its influence in PrismaSeT I Switchboard

Accepted Answer

!!!Confidential Content What is Eddy current? Eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor, due to Faraday's law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. They can be induced within nearby stationary conductors by a time-varying magnetic field created by an AC electromagnet or transformer, for example, or by relative motion between a magnet and a nearby conductor. The magnitude of the current in a given loop is proportional to the strength of the magnetic field, the area of the loop, and the rate of change of flux, and inversely proportional to the resistivity of the material. By Lenz's law, an eddy current creates a magnetic field that opposes the magnetic field that created it, and thus eddy currents react back on the source of the magnetic field. For example, a nearby conductive surface will exert a drag force on a moving magnet that opposes its motion, due to eddy currents induced in the surface by the moving magnetic field. This effect is employed in eddy current brakes which are used to stop rotating power tools quickly when they are turned off. The current flowing through the resistance of the conductor also dissipates energy as heat in the material. Thus eddy currents are a cause of energy loss in alternating current (AC) inductors, transformers, electric motors and generators, and other AC machinery, requiring special construction such as laminated magnetic cores or ferrite cores to minimize them. When does Eddy current become significant?Eddy current is not significant below 630 A. The IEC 61439-1 says that for more than 630 A Eddy current will be present and design has to ensure that additional thermal effects relating to the eddy currents and current displacement are considered in design (IEC 61439-1 : 2011, Sec. 10.10.2.2.3-b). How is the effect of Eddy current managed in PrismaSeT I?Induced Eddy current also depends on the design as explained below Fig 1 shows a single phase electrical conductor which is passing through a metallic plate. This will induce a magnetic field in the plate as shown in the figure and it will cause eddy current.Fig 2 shows the 3 phase electrical conductors which are passing through a common cut out in a metallic plate. In this case, there will not be any magnetic field induced in the metallic plate as vector summation of the magnetic fields induced by each phase will become zero.Fig 3 shows PrismaSeT International busbar architecture which is similar to the configuration of Fig 2. Hence, ideally there can not be any Eddy current induced in the supports.Fig 4 shows cutouts in PrismaSeT International form partitions when rated current is more than 630 A which is similar to Fig 2. Hence, ideally there can not be any Eddy current induced. There are no defined limits by the standards for Eddy Current. But, by design there cannot be any high eddy current in PrismaSeT I. The entire PrismaSeT I offer is type tested for temperature rise as per IEC 61439-1. Hence, it is not required to be worried unless and until there is an excessive temperature rise. Induced Magnetic Fields Arrangement in PrismaSeT IHow does aluminum help to reduce Eddy current in PrismaSeT I for Gland Plate and Busbar Support instead of steel ? Normally for steel, two types of magnetic losses occur, Eddy Current Loss and Hysteresis loss. As aluminum is a nonmagnetic material, Hysteresis loss does not occur and the induced eddy current is normally less compared to steel. Hence, when the rated current is more than 630 A and it is not possible to implement design as Fig. 2, aluminum sheet can be used in PrismaSeT I to minimize Eddy current effect (For example, cable gland plate).
