Browse the most current issue of Design World and back issues in an easy to use high quality format. Now, lets take a look at the wiring diagram. Single-Phase Systems vs. Three-Phase Systems, 22. A simple rearrangement of contacts can provide a tank-fill function as well. Looking at Figure 3 and the two points below, the same installation can have different functions depending on wiring. In short, a float switch is a mechanical switch that floats on top of a liquid surface. You can also transmit the Quality for this channel. Apparent Energyis accumulated by adding apparent power once a second. 0000001388 00000 n You can toggle the sliders to see more data, and there is a lot to see! These operate from a zero bar pressure choose the For the best experience on our site, be sure to turn on Javascript in your browser. USA: +1.518.770.0180Int.

In my example, I dont need the Max and Min voltage sent over MQTT or REST, but you can turn them on if you need to see this retained data. You consent to our cookies if you continue to use this website. The Quality indication can be turned on and off for each channel. The fun starts with understanding that most loads are not pure heating elements (a red hot glowing resistor). Which connection is better for Capacitor Bank Star or Delta? %PDF-1.3 % Using two pilot devices to control the motor allows for more efficient operation of the motor. 1-800-429-0800 | Mon-Fri: 8:00 AM to 5:00 PM EST. And all information provided in this blog is for general knowledge only. So in normal conditions, the motor will on, and when the water got filled in the tank the motor will be turned off. But if you have one, do install it (Wye configuration). If you are connected to voltages above 600 VAC for example, you can use a potential transformer (PT) to drop the voltage down, and then configure its ratio. A contact that under normal conditions does not have continuity through it. In the above image, you can clearly see how the spring clamps on either side of pin 3 are removed. Properly installing and wiring of the float switch ensures itll work as intended. They include resistors, inductors and capacitors, and all these change the shape of the current flowing through the load, and thus it is no longer both sinusoidal or in phase with the voltage. Complete the questions to find suitable valves directly: Indirect operated solenoid valves need a pressure differential over the inlet and outlet port for SJE-Rhombus 1066533, 3221W401H6A17G19B, Duplex Alternating Control Panel with 3 Float Switches, 208/240/480 Volts, 3 Phase, 6-10 Amps, Indoor/Outdoor 4X Enclosure, Skip to the beginning of the images gallery, 548363_1_SJE Rhombus Model 322 Control Panel Installation Manual.pdf, 548363_2_SJE Rhombus Model 322 Control Panel Specifications.pdf, NEMA 4X (ultraviolet stabilized thermoplastic with removable mounting feet for outdoor or indoor use), IEC motor contactors control pumps by switching electrical lines, Multi-tap transformer (208/240/480 VAC primary) provides 120V control/alarm voltage, Motor protective switches provide adjustable overload, branch circuit protection and pump disconnect, Alternating circuit board provides pump control and alternation (U.S. Patent # 5,909,532), Green pump run indicator lights (mounted on circuit board), Alarm/control fuse (mounted on circuit board), Float status indicator lights (mounted on circuit board), Float switch terminal block (mounted on circuit board), HOA Switches for manual pump control (mounted on circuit board), Control ON/OFF Switch (mounted on circuit board), Includes three SJE SignalMaster Normally Open (pump down) control switches, Red alarm beacon provides 360 visual check of alarm condition, Alarm horn provides audio warning of alarm condition (83 to 85 decibel rating), Exterior alarm test/normal/silence switch allows horn and light to be tested and horn to be silenced in an alarm condition, Alarm automatically resets once alarm condition is cleared, Horn silence relay (mounted on circuit board), Entire control system (panel and switches) is UL Listed to meet and/or exceed industry safety standards, Dual safety certification for the United States and Canada, Complete with step-by-step installation instructions. For a single function float switch, the ground wire needs to always be properly grounded. proper We dont pad print the terminal numbers on any unused pins. Where things could get a little more interesting is when we get to the power and energy points. Uses energy as long as electrically energized. Pilot devices include automatic switches such as float and pressure switches, as well as indicating lights. The alternating action equalizes pump wear. This is useful for testing the condition of the motor and verifying the direction of rotation.

When the switch is moved to the HAND position, the magnetic starter is energized. With those three main settings (Delta or Wye, CT type, CT size), click Save, and you should see some meaningful data straight away. Some very fine energy data there. If this channel goes over or under range for example, you will get a bad quality value. Important Note: Different float switch brands and types classify NO and NC differently. Each phasesNet Energyis the 1 second sum of the True Power. Once you have things wired up and the module installed, lets get to configuring the module. Note that you dont have to name and configure all 64 channels, but instead, just the ones that you require for your application. Speaking of data channels, lets take a look at some of them. Net Reactive Energyis accumulated by adding the reactive power once a second. JavaScript seems to be disabled in your browser. The black color wire is common, the Blue color wire is NC(Normally Closed) and the Red Colour wire is NO(Normally Open). Here, I have turned on the Public Access switch for this channel, which will report every change in value, and thus use some data bandwidth. We also share information about your use of our site with our social media, advertising and analytics partners who may combine it with other information that youve provided to them or that theyve collected from your use of their services. We recommend using 0.333 VAC current transformers (CTs) as they are smaller, cheaper, lighter, more accurate and safer than their 5 amp counterparts. So before executing or doing any electrical related work please verify and gather authorization. If the water level is low, both float switches are normally open and the motor does not run. If an alarm condition occurs, the alarm switch activates the audio/visual alarm system. When the contact changes its state it permits the flow of current by closing its contacts. This module will allow you to measure live power and energy consumption of any three, twin or single phase load in Delta or Wye configuration up to 600 volts. Clip, share and download with the leading design engineering magazine today. After the type of load is set, the next two important configurations are the CT Signal Output type (voltage or current) and Rated Current value. Scaling is generally left as default, and the filtering can be useful to dampen noisy values. only An auxilary device that provides indication or control of a process to an operator. Lastly, toggle on Writable if you want to be able to reset the Max and Min values via the REST or MQTT interface. The rest of the main configuration page is optional.

By selecting 'Other', This circuit shows the arrangement for a tank-drain function. If toggled on, the blue LED on the module will turn yellow if any channel goes out of its range. When you look at the top of the module, you can see some differences there as well. Low-Voltage Release vs. Low-Voltage Protection, 4. 0000000824 00000 n The power module energy calculations are the same power values but are the summed values over time. It can either be fixed to a bracket on top of the water tank, or along the side/pipe running down inside the tank. Why Semiconductor does not obey Ohm's Law? Indirect operated: from 0.5 bar pressure diff. The store will not work correctly in the case when cookies are disabled. Total Net Energyis the sum of the true power for all three phases. Once complete, be sure and click Save in the top right corner. The type of medium determines the choice of material for the seals. Since our price for this product is lower than MAP, the manufacturer does not allow us to display our lowest price until you place the product in the shopping cart. guideline for sizing: Solenoid valves are supplied with a coil of choice for alternating current (AC) or direct current Like anygroovI/O module, you will find it in the I/O menu. The function means if they are normally open (NO) or normally closed (NC).

Hb```f``-b`c```d@ AV(>6q00lq19:Nn^}!&AD#+| The interesting thing about this is that we store the energy totals to non-volatile memory on the module every 30 seconds. With only a single pilot device the motor would only drain a small portion of the tank and would be subjected to multiple starts and stops. If you want to set minimum current or voltage thresholds (for example, you dont want to measure a low overnight current or voltage as part of your energy calculation) you can set them up in the appropriate section here. as a choose the material for the valve body and seals. 47 0 obj << /Linearized 1 /O 49 /H [ 1394 384 ] /L 84797 /E 68636 /N 4 /T 83739 >> endobj xref 47 48 0000000016 00000 n 0000001307 00000 n 0000001778 00000 n 0000002000 00000 n 0000002208 00000 n 0000002936 00000 n 0000003426 00000 n 0000003896 00000 n 0000004279 00000 n 0000011161 00000 n 0000011182 00000 n 0000012026 00000 n 0000012047 00000 n 0000012853 00000 n 0000012874 00000 n 0000013654 00000 n 0000013675 00000 n 0000014453 00000 n 0000014474 00000 n 0000015368 00000 n 0000021480 00000 n 0000021928 00000 n 0000022256 00000 n 0000022963 00000 n 0000023413 00000 n 0000023859 00000 n 0000024560 00000 n 0000024893 00000 n 0000025351 00000 n 0000037586 00000 n 0000037607 00000 n 0000038479 00000 n 0000038500 00000 n 0000039301 00000 n 0000039322 00000 n 0000040147 00000 n 0000040285 00000 n 0000040424 00000 n 0000040478 00000 n 0000040530 00000 n 0000067361 00000 n 0000067509 00000 n 0000067627 00000 n 0000067918 00000 n 0000068233 00000 n 0000068351 00000 n 0000001394 00000 n 0000001757 00000 n trailer << /Size 95 /Info 46 0 R /Root 48 0 R /Prev 83729 /ID[<860a0f502235c6431d2ad80a9c8db00d><860a0f502235c6431d2ad80a9c8db00d>] >> startxref 0 %%EOF 48 0 obj << /Type /Catalog /Pages 35 0 R /JT 45 0 R /PageLabels 34 0 R >> endobj 93 0 obj << /S 148 /T 279 /L 326 /Filter /FlateDecode /Length 94 0 R >> stream Therefore, it is capable of sending a signal to: trigger a motor to fill the tank, a valve to open to empty the tank, high water level alarm, or both depending on the media level within the tank. 29 0 obj << /Linearized 1 /O 31 /H [ 619 226 ] /L 174157 /E 52850 /N 4 /T 173459 >> endobj xref 29 9 0000000016 00000 n So if apparent power is the source, and the load uses different parts of it as shown by the true and reactive power, how can we quickly see what the ratio of used versus rejected power is? Public Access is also required for getting your data via the REST interface. (semi-)direct operated solenoid valves can be used. diagram shows the flow when the coil is powered. This is because you might have some applications with up to 600 VAC connected to pin 3, and we need the physical clearance of all other terminals around it to provide the safety isolation. Once the water got filled, the motor will be turned off automatically. Single function float switches are either NC or NO and then they have a common and ground wire. The electrical wire needs to be fixed in a position that isnt going to change the depth of the float switch, as seen in Figure 2. Negative Energyis accumulated by adding the true power only when it is negative. Of course, you could also configure the module from PAC Control or CODESYS, if youre using either of those control engine runtimes.
