Tubewell Irrigation Stop Timer (TIST) is "Trade Mark" of Multi Electroni-Cal Systems Co. for Microcontroller based Motor Controller with in-built Stop Timer. The device works as Agriculture Irrigation Stop Timer. The Tubewell Motor is run for set duration. After the passage of set duration, Motor is automatically stopped. There are so many brands of Single Phase Preventor (SPP) in the Indian Market and don't have Stop Timer. Our product has Single Phase Preventor with in-built Stop Timer. TIST based SPP has provision to set the RUN duration using external 9 Volt battery also. The battery must be removed after setting the RUN duration. The device automatically saves the RUN duration internally. Similarly, during RUN, if there is power failure, the pending duration is internally saved automatically. On resumption of Power supply, the saved/ pending duration is automatically completed by the TIST. Need Of Single Phase Preventer: In agriculture sector, most of the motors are three Phase Induction type. Either Monoblock or Star-Delta type Motor is used by the farmers. The MonoBlock Motor has Three Terminals to apply directly three phases. The start -Delta type Motor has 6 wires. The connection of these wires in initially according to Star Topology. After few seconds, the connection topology is changed to Delta. According to the type of motor, the mechanical starters also are different for these two types of motors. Direct-On-Line (DOL) type starter is used with Monoblock Starter. The Star-Delta type starter is used with Motor having 6 wires. The DOL starter has only Two buttons namely Start and Stop. Star-Delta type has Three buttons, Start, Run, Stop. The user have to press the appropriate buttons manually. If the power Supply is properly balanced, only then Motor should be operated otherwise motor may get overheated. Every human can not measure the Electric voltage and hence monitoring Three phase by humans is dangerous and life threatening. So, Electronic Systems have been developed to check the Power Supply within the safe limits and then RUN motor automatically. This product protects the Motor Run in case of Power fault. Mostly occurring faults is Voltage unbalance. This situation is called as single phasing. The product to detect Single Phasing Situation and then protect the Motor, is called as Single Phase Preventor (SPP). The Single Phase Preventor (SPP) is quiet useful to ensure safe operating of Motor even in absence of farmer. Irrigation Stop Timer Need: Usually available SPPs are designed with objective to automatically run Motor if Power is proper. There is no provision to stop motor automatically or remotely in those SPPs. Any human have to visit the Motor location to stop it. If meanwhile the farmer need to go elsewhere, can not go because there is risk of overrun of the water in the field. TIST has been designed to fulfill this requirement of farmers. The farmer can set the estimated run duration of irrigation in the TIST based product. The Motor will RUN for the set duration and farmer can do some other activity anywhere without any risk of overrun.
This product is Single Phasing preventor (SPP) with Programmable Stop Timer using Buttons. This product is an Agriculture Irrigation Stop Timer and the farmer can easily set the RUN duration. If there occurs power failure, then on power resumption, the pending duration is autmatically recovered to complete the total set duration. This product has been termed as Tubewell Irrigation Stop Timer (TIST) by the company. It is useful for the farmer to manage other activities along with irrigation. TIST is registered brand name of company in India for the Timer based Irrigation systems. TIST has the feature to set the RUN duration using external 9 Volt battery. After setting the duration, the Battery must be removed. The TIST device saves the duration internally automatically. When fails during run, the pending duration is also saved internally automatically. When, power supply resumes, the saved/ pending duration is used automatically by the TIST. It has feature to Stop the Motor if there is any unbalance in the power supply. In fault situation, the Timer is stopped automatically. Why to use TIST based products : In the market, there are so many brands of Single Phase Preventor and Drip Irrigation Timers. The Drip Irrigation Timers available in the marketare too costly and as well complex to operate by the common man. In India, most of the farmers are very less educated, so it becomes difficult for them to learn the operation of technically complex gadgets. TIST based products have been designed keeping the operational algorithm vary simple. The simplicity reduces the cost as well makes it user friendly. TIST based present products have only three/four buttons with single function of each button. The display used in TIST based products is Seven Segment type. Seven Segment type display can tolerate tuff environmental conditions usually found in the open agriculture region, like Wet/ dirty/ Greasy hands of user, Too Hot or Cold atmosphere, too fast air flow (Storm) etc. In such situation, LCD or other types of displays can not work properly and longer and need careful installation and handling. As well cost and size of other displays is more than normal Seven Segment type. Further, to keep display size minimum possible, company had designed TIST products to display multiple information parameters in sequential manner. All these methods of Hardware simplicity, operation simplicity with feature rich Software algorithm, the unique performance has been realized in TIST based products.
This card has been designed for industrial applications where the speed & direction of Stepper Motor is to be controlled by user. This card has provision to select microstepping. The direction, enable & pulse are the signals available to fed into Stepper Driver.
This product has been designed to record the performance of Invertor - Battery. The charging-discharging, load & charging current etc all parameters are stored in the internal memory. The stored data can be seen on LCD or be transmitted to computer through serial Port in Excel Sheet Format.
This product has been designed for rural market of India. Long electric supply failure is a big problem in rural area, so single battery is not sufficient to provide back up for longer duration in summer season. Most people use two batteries in series or parallel with inverter. Both these configurations have own disadvantages. The present product has been designed to handle the battery problems. This automatically manages the battery for the longest possible back-up & fast charging.
We have designed control card to make Summer Cooler Digitally controlled Smart Device.
We have designed a low cost irrigation stop timer, which is easy to operate. This product has been registered with TIST brand name in India. TIST stands for Tubewell Irrigation Stop Timer. This product can be interfaced with existing Single Phase Preventor (SPP). Already installed Single Phase Preventor (SPP) can be converted to Irrigation Stop Timer after making electrical connections with TIST. TIST can be detached from Single Phase Preventer (SPP) when continuous day-night irrigation is required. The farmer can get parallel working by doing some other work as long irrigation duration is completed without being present at irrigation site. After, the passage of set irrigation, the farmer may set the duration of next irrigation. Which Type of Motor can be Controlled: This product has been designed to control the Single Phase Preventor (SPP). The SPP must be already installed. The three wires of TIST based TIMER (TMR1 model ) need to be connected inside the SPP by some Electronic Mechanic. As the SPP is designed either for DOL or Star-Delta type motor starter, any type of Motor can be controlled using SPP and TIST based TMR1 pair. This features makes TIST based TMR1 universally useful for irrigation motor run duration control. Industrial Use : TIST based TMR1 timer can be used to control any product which needs some Low and High Impedance type input signals for Run and Pause of the process. During normal operation, TIST based TMR1 sends High Impedance Logic and when time has been completed, it sends out Low signal.
