However,\nrelationship between fuel valve actuator and damper opening does not remain linear due to complex nature of\ncombustion process. Hence, control signal received from controller has to be modified for optimum results of\ncombustion. For this purpose, complete range is split in number of steps and each step can be multiplied by\nfactor which is expected to give optimum combustion results. Multiplying factor can be set at any value\nbetween 0.5 – 1.5 independently for each step. Output signal is clamped to either minimum or maximum\nvalues whenever it tries to go beyond these values in any step. Diligent RATIOCON 4-20I 16 is one such\ncontroller designed by M/s Diligent Micro Controls to accept 4 – 20 mA dc signal from either pressure /\ntemperature controller and provide modified signal which is also lying in 4 – 20 mA range.\nThis controller is housed in standard 96 x 96 mm plastic enclosure and it works on 230 V +/-10%, 50 hz, 1 ph\nac supply.\n1. Description:\n‘Diligent Ratiocon 4-20 I 16’ accepts 4-20 mA signal at the input terminals on the rear panel of the\nbox. This range is split in 16 steps and 16 presets are provided to modify each step independently\nwith multiplier between 0.5 to1.5. 16 LEDs are also provided and LED lights when the input signal\ncrosses the step value. Modified output of 4-20 mA, is provided at the out put terminals on the rear\npanel of the box. When ever out put tries either to go below 4 mA or to go above 20 mA as a result of\nmultiplying factor setting, internal circuit clamps output to 4 mA in the first case and 20 mA in the\nsecond case. Clamped status of <4 mA and > 20 mA is indicated by respective LED on the front\npanel. Rear panel has two terminals which have to be shorted together during Calibration Mode.\nPower supply Phase, Neutral & Earth are connected at the respective terminals on the rear panel. This\ncould either be 230 V or 110 V +/-10%, 50 hz, 1 phase AC. RATIOCON has 3 digit display which\nnormally indicates the out put current signal and when the switch on left top corner is pressed it\nindicates the input current; either actual or calibration.\n\n2. Operation:\nDiligent RATIOCON becomes operational as soon as the a.c. power supply is connected to it.\nRATIOCON has two modes of operation; namely Calibration Mode and Normal Mode.\nMICRO CONTROLS\n\nRATIOCON operates in Calibration mode when corresponding terminals on the rear panel are looped\ntogether. In this mode internal variable current source is connected to the input stage of RATIOCON\nand its out put can be varied by the knob located on right top corner. The value of this current can be\nread on the digital display by pressing the push button. Calibration procedure is as follows –\na. Turn Calibration Adjustment knob fully anticlockwise till the current value drops below 4 mA.\n‘<4 MA’ LED will light as soon as out put current drops below 4 mA and out put current will be\nclamped to 4 mA.\nb. Turn the Cal. Adj. slowly in clockwise direction till the first step LED (marked ‘4’ on the panel)\nlights.\nc. Adjust preset below this LED to read the desired out put value on the digital display.\nd. Repeat ‘b’ & ‘c’ above for all the remaining steps.\ne. Continue to increase the calibration current beyond 20 mA. ‘>20 mA’ LED will light as soon as\nthe out put current tries to go beyond 20 mA. Out put current will be clamped beyond this at 20\nmA.\nf. This completes the calibration and the loop wired between two terminals on the rear panel can\nnow be removed.\nRATIOCON enters NORMAL Mode as soon as the loop wired for calibration, is removed. In this\ncase input stage of RATIOCON now receives input signal directly and will generate out put signal\naccording to the preset program.\n3. The connections details are given on the rear panel and are self explanatory.\n4. This instrument is not site maintainable.\n5.

Discription:\nStabmon is customized protection unit for 3-phase ac stabiliser. It is housed in strong & sleek m.s.\nenclosure. It operates on 230 V, 1 phase ac supply. Status & Fault LED display is provided on the\nunit and is very useful during commissioning and fault finding. Over load adjustment over 95% to\n105% of rated current, is provided on the unit. Local Reset Switch is provided to reset Stabmon after\nit trips on fault. A toggle switch is provided to enable and disable ‘Single Phasing Protection’ and\nits status is indicated by the two-color LED.\n2. Operation:\nStabmon require 230 V, 1 phase ac supply for its operation. 3-phase supply enters the unit at\nterminals Rs, Ys & Bs and leaves from terminals Rl, Yl & Bl for connection to load. Phase current\nof each phase is monitored continuously. So long the current is present in all the three phases and is\nbelow the set limit, control relay inside is in energised state. Mains, Load and Fault LEDs are\nlighted. Status of ‘Single Phasing Protection’ is indicated by last LED. When the switch on the rear\npanel is pressed, this LED becomes red and when that switch is released, color changes to green.\n3. Time-delayed Overload Protection :\nWhen any of the phase current exceeds preset limit for more than the permitted preset time (5sec.)\ncontinuously, Stabmon switches off internal control relay and latches it in this state. ‘Overload’ LED\nlights. ‘T.DLY’ LED lights as soon as overload takes place and stays on till it last or till the elapse of\nthe preset time, whichever is earlier. Overload adjustment is provided to adjust trip level from 95%\nto 105% of the rated current.\n4. Single Phasing Protection :\nEach phase carries current under normal condition and Stabmon continuously monitors it. Internal\nrelay remains energised so long all the three-phase carry current. However, when either one or two\nphases become open, internal relay switches off and is latched in this state. ‘Single Phasing\nProtection’ feature is different from the one understood conventionally. This is so because AC\nstabiliser is required to feed different loads from its phases and, therefore, currents in the phases\ncould be different. In extreme case, it may be required to operate with current in its one or two phase\nbeing zero or below the minimum sense level set for the circuit. In such case, Stabmon will not\npermit its operation. Loads may be switched on/off randomly and this can cause load current to dip\nMICRO CONTROLS\n\n2\nbelow the minimum sense level momentarily. A short time delay of 2-3 sec. is provided to allow\noperation with such short lasting dips in phase current.\n\n5. Reverse Phase Sequence Protection :\nPhase sequence of the 3-phase supply is continuously monitored. If the sequence is normal, Stabmon\nrelay stays in on state. However, whenever this sequence becomes reverse, relay switches off and\nstays off until sequence is corrected by interchanging any of the two phases. LED designated as\n‘REV. PH. SEQ.’ on the display, indicates this fault.\n6. Local Reset :\nOnce Stabmon switches off internal relay and latches it in that state due to overload or single phasing\nfault, ‘Fault’ LED starts flashing and stabiliser is switched off. This state prevails until local reset\npush button on the front panel, is pressed by operator.\n7. Calibration :\nStabmon upto 10 Amps rating are directly calibrated and offered in our standard enclosures. For any\nother higher current ratings, standard 5Amp Stabmon is calibrated with customer-specified auxiliary\ncurrent transformer.\n8. Status & Fault Display :\n\nStatus & Fault display, is described below-\nTitle Description\n\nMains Lights when 230 V,1ph., ac supply is connected.\nLoad Lights when one or more phases carry current.\nS. ing Lights when one or two phases are lost and current through them\nbecomes zero.

Diligent Protector for AC applications\nDiligent AC relays are available for Over Load (OL), Single Phasing (SP), Phase Reversal\n(PR), etc. The overload relays are available in 1ph and 3ph types. 1ph-relays are useful on\nsingle phase load and can also used as economical solution for 3 ph applications whenever\nload is balanced. These are classified depending on the response to the overload condition and\nthe classification is as follows -\na. INStantaneous (INS) type. In this relay changes the state as soon as overload occurs.\nb. Time-Delayed (DLY) type. In this the relay changes the state only after elapse of present\nperiod from the time overload occurred & stayed.\nc. Jam (JAM) type. In this, the control relay does not respond to the overload condition for\na preset time from switching on the load but after elapse of this time, the relay responds\nimmediately to any overload.\n\nMICRO CONTROLS\n\n2\nInstantaneous type is primarily made for AC loads other then motor such as: transformer,\nheater etc. However, it has been also used along with other logic to control motor.\nTime-Delayed overload relay find wide use. The tie delay provided in the relay avoids\nnuisance tripping in response to transient overloads but switches off the load if overload\npersists beyond the specified time. Most of the loads in actual practice increase temporarily\nand the drive is usually designed to handle this type of overloads.\nJam type overload relay is quite unique and has made possible very reliable protection of\nloads such as Blower, Fans, Stirrer motors which was rather difficult to achieve with\nconventional thermal relay. Jam relay not only saves the motor, but restricts the possible\ndamage to the equipment & loss of production by advance intimation before catastrophic\nfailure takes place. Such situation, for example, can arise when ‘oil-starved bearings’ starts\nslowly seizing and if not attended in time can get heated and tear out the housing. Repair not\nonly costs in term of money but looses precious time. Similarly, jamming of conveyor can be\neffectively responded by the Jam relay and catastrophic failure there of can be averted.\nSingle Phasing (SP) protection in Diligent Protector relay is either Current Operated Single\nPhasing (COSP) or Voltage Operated Single Phasing (VOSP). COSP is realised by sensing\neach of the phase current continuously. As soon as current in any one phase is lost, control\nrelay changes the state. This greatly limits the heavy thermal stresses due to large current\nflowing in the connected phase-windings of motor. VOSP protection monitors all three supply\nphases and acts when one of the phases of 3 phase supply is missing. However, Should phase\nbe lost while 3 phase motor has already running, VOSP may not trip the motor because of the\ninduced voltage in the motor winding. However, COSP is effective even when the phase is\nlost while the motor is in operation.\n\n2. Diligent Protectors for DC Applications\nDiligent Micro Controls has also developed protection relays for DC loads such as DC motor,\nDC generator, Rectifier sets, DC electromagnet etc. These relays are available in three types:\nnamely INStantaneous, Time-Delayed and Jam type similar to the AC relays. DC relay\noperates from “75 mV standard DC shunt” and requires auxiliary supply for its operation.\nOptionally the relay can be made suitable to work with User-specified shunt.\n3. Diligent Protectors for AC or DC Under-/ Over-Voltage\nDiligent Protector for AC or DC Under-/Over-Voltage fault is designed to monitor the voltage\nlevel continuously and whenever it exceeds set limits for more than the set time, the relay\ninside picks up. This relay can be made auto reset type or manual reset type.\n4. Diligent Protector for Neutral-Earth Voltage\nDiligent Protector for Neutral-Earth voltage monitors this voltage continuously and whenever\nit exceeds set limits for more than the set time, the relay inside picks up. This relay can be\nmade auto reset type or manual reset type.\n5. Diligent Protector for Conveyor Jamming\nDiligent Protector for jamming of conveyor is unique. It allows conveyor motor to start\nnormally and monitors continuously current drawn by it during operation. It trips the motor\nimmediately when current exceeds the set JAM limit. This averts catastrophic failure and\nconsequential loss of production. This relay can be made auto reset type or manual reset type.\n\n6. Diligent Protector Shear Pin Replacement\nDiligent Protector for shear pin replacement is unique. Shear pin disengages the motor from\nthe load by breaking itself when load increases beyond the permissible level. However,\nreplacement of shear pin is associated with inherent uncertainties of material quality. This\nrenders shear pin protection less reliable. Diligent Protector Replacement for shear pin is\nunique. Not only it provides precise and repeatable protection but it also has provision to\nadjust the protection level which enables to match the protection to the load. This relay can be\nmade auto reset type or manual reset type.\n7. Diligent Protector for Lifting Electromagnet\nDiligent Protector for Lifting Electromagnet allows electromagnet to be switched on under\nnormal condition but when its current drops below the set level for more than prescribed\nperiod, Diligent Protector alarms the operator.\n8. Diligent Protector for Grinder Under-/Over-load\nThis is very special type of protection. Whenever grinders are working with full charge, it\ndraws large current initially and drops as grinding completes. Any prolonged operation after\ncompleting grinding, the material can burn due to over heating as well as energy will be\nconsumed without any useful work. Diligent Protector for ‘Grinder Under load’ will trip the\nmotor as soon as current drops below the set limit.\n9. Diligent Unique Protector for Blower / Fan\nConventional Overload protection is not at all suitable for Blower / Fans due to their starting\ncharacteristic. Diligent Unique Protector for Blower / Fan is really unique. It allows normal\nblower start up successfully; however, if blower motor draws more current than set limit, it\nimmediately trips the motor. This is very useful as blower/fan is most ignored equipment in\nmost of the industries and they suffer consequential catastrophic failure due to this negligence.\nDiligent Protector will trip the blower even at the onset of faults such as starving for\nlubrication, impeller unbalance, excessive vibration, interference due to broken parts, etc.\n10. Diligent Monitor for Solenoid Coil\nSolenoid valves are very critical in the process control and their healthiness is of utmost\nimportance. Diligent Monitor for Solenoid Valve, monitors the healthiness of solenoid coil\nduring operation. Should coil become open during operation, a potential-free contact closes to\ntransfer this information to centralized SKADA system or sound an alarm.\n11. Diligent Monitor for Heater\nIn some applications like sterilizing system in pharmaceutical industries, numbers of electric\nheater elements are used in banks to achieve acceptable sterilizing temperature. However,\nfailure of some elements does not become known until when finished goods start getting\nrejected during quality control. Loss is large at this stage. Diligent Heater Monitor gives alarm\nwhen number of available heater drop below the acceptable number.\n12. Auxiliary Supply:\nStandard auxiliary supply 230V, 110V, 24V AC or 24V DC can be specified. Relays can be made to\noperate on any other user-specified supply.\n\n4\n\n13. Output Contact:\nOne Change-over contact rated at 4 Amps (resistive) at 230V ac, is provided. This contact stays in\nactuated state as long as long fault does not exist.\n14. Status & Fault Display:\nRelay carried unique display which indicates various status and also the fault on which the load has\nbeen switched off. It also has LED which glows steady under normal condition but starts flashing\nwhen relay trips. This is very useful feature where the tripped relay has to be spotted among the cluster\nof relays & contactors. This along with the type of fault indication immensely simplifies fault\ndiagnosis by identifying the defaulted zone. This results in considerable reduction in MTTR (Mean\nTime to Repair) and improving system availability.\n15. Post Fault Reset:\nRelay tripped in response to the fault, has to be restored for normal use again. Depending in the nature\nof fault and requirement of particular application, this restoring can be effected either automatically\n(AUTO) or manually (MAN) or combination of auto-manual (A/M). The faults which are not serious\nare cleared by known corrective action and the relay in such case is made to reset by itself or clearing\nthe fault. Operator does not have to go to control panel to reset the relay and he can switch on the load.\nSuch faults are, for example, phase reversal, normal overload etc. However, serious faults, such as,\nsingle phasing, mechanical jamming, bearing seizure, short circuit etc. required to be properly\ninvestigated before switching on the load again. Hence in such cases, relay is designed to disallow\nrestart unless relay is manually reset by an operator-in-charge. The 3rd type of ‘fault reset’ is very\ninteresting since Diligent Relays combine multiple protection in single unit. Some protection feature\ncould be serious while other may not. It is possible to built user-specified combination of reset logic in\nour relay. Thus, the relay is made very user-friendly.\n16.

One of the basic and common ways to obtain heat is by\nburning combustible fuels. However, such combustion must be controlled and safe. Safety of combustion is\nensured by monitoring flame. Flame is characterized by emission of wide spectrum of electromagnetic\nradiation starting from infra red, visible light to ultra-violet radiations. Flame is also known to generate ions\nin its envelope. Type of fuel and that of burner decides which one of these radiations predominate. For\nexample; flame of coal or oil is usually very bright and yellow in color, flame of light oil like kerosene or that\nof hydrocarbon gas is light blue and flames of some gases may be even dull reddish. In addition to this,\nintensity of flame could differ widely depending on the type and size of flame. Hence different techniques\nhave evolved and new are being developed to detect and monitor flames. DILIGENT MICRO CONTROLS\nhas developed wide range of flame monitors “Diligent Flameye”. In addition to the basic flame monitor we\nhave developed intelligent versions which provide\nBuilt in delay for flame ON or OFF status change,\nMultiple contacts out puts,\nDual flame monitor,\nDual flame monitor with AND logic,\nDual flame monitors with OR logic,\nDual flame monitor with mixed sensor types,\nInverse Mode of operation of control relay,\nWeatherproof enclosure flame monitor.\nAC power supply of 230V +/- 10 %, 50 Hz, 1ph ac is required for operation of all Standard Flameye models.\nHowever, versions suitable to work with other standard AC or DC supplies can be provided on request. One\nchange-over potential free relay contact rated at 4 amps (resistive) at 230 V ac, is provided in all standard\nunits. Multiple potential free contacts can be provided as optional.\n\nDiligent Flameye are classified based upon sensing technique used and these are as described below-\nDiligent Flameye PR\n\nFlame produced while burning diesel, furnace oil, HSD, LHSH, etc., is bright and yellow. PhotoResistor type\nphotocell have excellent response to the visible light spectrum and, therefore, is the most reliable and cost\neffective choice to detect such flame. Diligent Flameye PR provides appropriate bias to the basic PR sensor\nwhich generates change in its resistance commensurate with the amount of visible light radiations received by\nit. This change is received by Flameye which conditions and amplifies it before comparing with preset\nreference. When signal level crosses the reference, internal relay picks up. This relay goes back to off state as\nsoon as the radiations falling on PR sensors cease. Basic signal from PR sensor is very small and should be\ntransmitted over screened cable to Diligent Flameye and his cable should be preferably laid away from power\ncable.\n\nMICRO CONTROLS\n\n2\n\nDiligent Flameye PV\nPhotoVoltaic photocell is another basic sensor which has excellent response over visible portion of\nelectromagnetic radiations. It produces electric dc voltage in mV range in response to the intensity of light\nfalling on it. This small signal from PV sensor is conditioned & amplified by Diligent Flameye PV and then\ncompared with preset reference. When signal level crosses the reference, internal relay picks up. This relay\ngoes back to off state as soon as the radiations falling on PV sensors cease. Basic signal from PV sensor is\nvery small and should be transmitted over screened cable to Diligent Flameye and his cable should be\npreferably laid away from power cable.\nDiligent Flameye UV\nPR and PV sensors are excellent choice when the flame is bright yellow. However these sensor hardly\nrespond to a flame which is blue, light blue or nearly invisible like the one that exist while burning of light\noil, LPG gas, Natural gas, propane, butane, methane, etc. Such flame is sensed by sensing the radiations in\nultra-violet range which are associated with all combustion processes. Gas filled UV photocell or\nsemiconductor type UV photocell is used to receive these radiations from flame. These cells require correct\nbiasing voltage which is provided by Diligent Flameye UV. Tiny signal in micro ampere is generated by UV\nsensor and is then transmitted over screened cable to Diligent Flameye UV. This cable must be of very good\nquality having low capacitance and high grade insulation. This small signal from PV sensor is conditioned &\namplified by Diligent Flameye UV and then compared with preset reference. When signal level crosses the\nreference, internal relay picks up. This relay goes back to off state as soon as the radiations falling on PV\nsensors cease.\nDiligent Flameye ION\nIons are produced in the envelope of all types of flames due high temperature in side. This technique picks up\nthese ions under the influence of appropriate bias voltage and generate tiny signal which is then transmitted\nover screened cable to Diligent Flameye ION. This cable must be of very good quality having low\ncapacitance and high grade insulation. This small signal from ION sensor is conditioned & amplified by\nDiligent Flameye ION and then compared with preset reference. When signal level crosses the reference,\ninternal relay picks up. This relay goes back to off state as soon as flame extinguishes. This technique relies\non collecting of ions in the flame and hence the sensor electrode must always be in good contact with the\nflame and flame must also be in continuous contact with electrically earthed body. Any violation of this will\nmake the flame signal disappear.\nFlame Sensors\nAll the flame sensor except ION sensor are electronic sensors and hence their operating environment\ntemperature must not exceed 55 deg C. Higher temperature, though may not lead to malfunctions, can\nseverely affect the useful life of the sensor. All of the sensors, therefore, carry any testing warranty and none\nof these carry conventional warranty. ION sensor is electrode with high grade insulator and high temperature\ncollecting rod. Care is necessary to ensure that the scaling on rod is periodically removed, contamination that\ncould reduce insulation level of rod, should be avoided and cleaned if noticed.\nWarranty\nDiligent*FLAMEYE carry a warranty for period of 12 months from the date of delivery.
