EN 50019 demands additional measuresfor operating motors with “increased safety” type ofprotection “e”. These measures provide an enhanced degreeof safety for protection against impermissible hightemperatures and against the development of sparking andarcing on the motors, which does not usually occur undernormal operating conditions. The motor protective devicesused for this are operated outside of the EEx e area and mustbe certified by an accredited certification authority.The guidelines on the application of Directive 94/9/EC(ATEX100a) on the approximation of the laws of theMember States concerning equipment and protectivesystems intended for use in potentially explosiveatmospheres will be enforced as of 30 June 2003.The thermistor overload relay EMT6 is approved by the PTBaccording the 94/9/EC (ATEX100a) Directives.h Number of the EU certificate of compliance:PTB02ATEX3162.07/03 AWB2327-1446GB EMT6 thermistor machineprotection relaySystem overviewFigure 1 :Overload protection relays EMT6, EMT6-DB andEMT6-DBKUnit description To protect the machinery from overload, direct temperaturemonitoring systems can be used in addition to current-dependent protective devices. The EMT6 overload relaysmonitor the thermistor sensors used for monitoringtemperature and switch off the power relay in the event ofoverheat in the machinery.Direct temperature monitoring using thermistorsThe motor current can also be used to monitor motorovertemperature in addition to the indirect method oftemperature monitoring. For this, the motor manufacturerimplements integral thermistors in the motor windings.Apart from the sole purpose of motor protection, thermistorsare also used to monitor the temperature of motor andmachine bearings. They are also commonly used forUnit description07/03 AWB2327-1446GBtemperature monitoring of heating systems, heating circulation fans, in the windings of various sizes of transformers, for generator protection as well as for monitoring gaseous or liquid coolants, and temperature monitoring of non-electrical mechanical equipment. Thermistors are step-action temperature sensors, also referred to as PTC resistors or positive temperaturecoefficient resistors. Their resistance changes sharply when a defined temperature is exceeded.The thermistors are monitored by the thermistor overload protection relay EMT6.Thermistor protectionFor the protection against overtemperature, up to six PTC resistor temperature sensors to DIN 44081 PTC Resistors, or up to two temperature sensors to DIN 44082 Triple PTC Resistors with a PTC resistance of R K F 250O , or nine sensors with a PTC resistance of R K F 100O can be connected to the EMT6 terminals T1-T2 (a Fig.7, Page 18).Figure 2 :Characteristic curve for monitoring temperature with athermistorThe EMT6 switches off at R =3600O g 10% and switches on again at R =1600O g 10%.

This must be ensured by circuit design.jWarning!A separate overload protection system must be installed for the electrical equipment.Unit description 07/03 AWB2327-1446GBEMT6EMT6(230V)EMT6-K EMT6-DBEMT6-DB(230V)EMT6-KDB EMT6-DBKFunctionAutomatic Reset+++++ Manual Reset––+++ Detection ofshort-circuit inthe sensor circuit–+–++Zero-voltagesafety––––+ Operator controlTest button––+++ Reset button––+++ Remote reset––+++ Selector switchMANUAL/AUTOreset––+++DisplayOperatingvoltage+++++ Tripping+++++ Fault short-circuit–+–++ VoltageMultiple voltageof 24 V to240V h/H+++++Single voltage230V h+–+––EMT6 thermistor machine protection relay07/03 AWB2327-1446GBReset after triggeringThe error message of the standard EMT6 is automatically reset after the equipment (motor winding) temperature has dropped to a sufficiently low level. The operating mode of the EMT6-DB, EMT6-KDB and EMT6-DBK variants can be set to “Automatic” or “Manual reset” using the selector switch. In automatic mode, the devices are reset automatically as described above. In manual mode, they are reset after the motor has cooled down.The EMT6-DB, EMT6-KDB and EMT6-DBK have anadditional option of connecting a button as a remote reset for manual mode.Zero-voltage protectionZero-voltage protection means that the error message is retained even after loss of the supply voltage. Zero-voltage protection can be enabled or disabled on the EMT6-DBK. If the equipment has not yet cooled down sufficiently after power is returned, the relays with disabled zero-voltage protection will also be tripped again. The message of devices with disabled zero-voltage protection will be lost only if power is returned after the equipment has cooled down during an extended period of power loss.jWarning!To ensure explosion-proof operation, it is permitted only to reset/switch on the motor manually after it has cooled down, or to switch it on automatically via a control interlock circuit for the motor or electrical machinery.A manual reset may be carried out on-site or from the control room by trained personnel.Unit description07/03 AWB2327-1446GBShort-circuit monitoring of the thermistor circuit The sensor circuits of all EMT6 units are equipped with a wire-break (open-circuit) safety sensor circuit. The sensor circuits of the EMT6-K, EMT6-KDB and EMT6-DBK have additional short-circuit monitoring in the sensor circuit which immediately switches off the relay when the resistive load of the sensor circuit drops below a minimum value.When using the EMT6 or EMT6-DB, a current monitor (a Fig.3, Page 12) must be used in the thermistor circuit to monitor short-circuits.jWarning!Particularly in EEx e applications, an automatic restart must be prevented after an interruption of the control voltage. This is prevented safely by means of the latching mechanism of the power relay (a Fig.4, Page 16).hZero-voltage safety can be disabled at the EMT6-DBK by means of a wire jumper between terminals Y1-Y4.hThe short-circuit monitoring of the EMT6-DBK can be disabled by means of a wire jumper between terminals Y1-Y3 (a Fig.7, Page 18).j Warning!Short-circuit monitoring is essential in the sensor circuit to monitor EEx e motors. Monitoring of short-circuits may not be disabled.hCaution!The maximum short-circuit current of the thermistor input is 1.9 mA.07/03 AWB2327-1446GB EMT6 thermistor machineprotection relayFigure 3 :Short-circuit monitoring of the thermistor circuitusing a current monitora Remote resetb STOPc START07/03 AWB2327-1446GB2ConfigurationMonitoring overload of motors in the EEx e area The “EEx e” type of protection for motors is achieved by means of special constructive measures. The motors are assigned to temperature classes based on the maximum permitted surface temperatures. The heating time t E and the ratio between startup current and rated current I A/I N are additionally calculated and specified on the motor.The safe locked-rotor time t E represents the time it takes for the rotor winding to heat up from its final rated operational temperature up to the limit temperature at a starting current of I A.However, EEx e motors are not intrinsically safe. Explosion safety is only achieved by selecting further appropriate installation measures and operating conditions (PTB testing regulations), e.g. by combination of the circuit with a correctly rated and set temperature monitoring system. The machine manufacturer equips the machine at its critical temperature points with integral thermistors to DIN44081, which are selected according to the appropriate rated threshold temperature. They develop a high resistance after their rated response temperature is exceeded. The thermistors must be compliant with the following limits according to standards:•i NAT –5K: R F550O•i NAT +5K: R f1330O•i NAT +15K: R F4000OThe thermistor overload relay monitors the thermistors and switches an auxiliary circuit when the critical temperature is exceeded.Configuration07/03 AWB2327-1446GBApprovalsThe EMT6 overload relay has been manufactured incompliance with the IEC/EC 60947 low-voltage switchgear and DIN VDE 0660-303A regulations, and fulfils the 94/9/EC (ATEX 100a) guideline for protection of EEx e motors.Furthermore, motors can be explosion protected in zones 21 and 22 (areas with combustible dusts) in compliance with EN 50281-1-1 and EN 50281-1-2.The EMT6, EMT6-DB and EMT6-DBK relays are approved by the UL and CSA for the USA and Canada.Further approvals exist for c 0102II(2)GDU s•Romania ML PAT•Russia07/03 AWB2327-1446GB3InstallationNotes on installation The notes in the current AWA2327-1454 installation manualwhich accompany the devices must be observed duringmechanical and electrical installation of the devices.j Warning!To ensure explosion-proof operation, it is permitted onlyto reset/switch on the motor manually after the thermistorhas cooled down, or to switch it on automatically via acontrol interlock circuit for the motor or electricalmachinery.A manual reset may be carried out on-site or from thecontrol room by trained personnel.j Warning!Particularly in EEx e applications, an automatic restartmust be prevented after an interruption of the controlvoltage.

On-resistance is matched between switches to 0.5Ωmax and is flat (0.5Ωmax) over the specified signal range. Each switch can handle Rail-to-Rail ®analog signals. The off-leakage cur-rent is only 5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the pre-ferred solution over mechanical relays in automatic test equipment or in applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays.The MAX4664 has four normally closed (NC) switches,the MAX4665 has four normally open (NO) switches, and the MAX4666 has two NC and two NO switches that guarantee break-before-make switching times.These switches operate from a single +4.5V to +36V supply or from dual ±4.5V to ±20V supplies. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using ±15V sup-plies or a single +12V supply.ApplicationsReed Relay Replacement PBX, PABX Systems Test EquipmentAudio-Signal Routing Communication SystemsAvionicsFeatureso Low On-Resistance (5Ωmax)o Guaranteed R ON Match Between Channels (0.5Ωmax)o Guaranteed R ON Flatness over Specified Signal Range (0.5Ωmax)o Guaranteed Break-Before-Make (MAX4666)o Rail-to-Rail Signal Handlingo Guaranteed ESD Protection > 2kV per Method 3015.7o +4.5V to +36V Single-Supply Operation ±4.5V to ±20V Dual-Supply Operation o TTL/CMOS-Compatible Control InputsMAX4664/MAX4665/MAX46665Ω, Quad, SPST,CMOS Analog Switches________________________________________________________________Maxim Integrated Products1Pin Configurations/Functional Diagrams/Truth Tables19-1504; Rev 0; 7/99Ordering Information continued at end of data sheet.Ordering InformationRail-to-Rail is a registered trademark of Nippon Motorola, Ltd.M A X 4664/M A X 4665/M A X 46665Ω, Quad, SPST,CMOS Analog Switches 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSNote 1:Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- are clamped by internal diodes.

Do not exceed the absolute maxi-mum ratings, because stresses beyond the listed rat-ings can cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with supply pins (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices’ low switch resistance and low leak-age characteristics. Device operation is unchanged,and the difference between V+ and V- should not exceed 44V. These protection diodes are not recom-mended when using a single supply.Off-Isolation at High FrequenciesIn 50Ωsystems, the high-frequency on-response of these parts extends from DC to above 100MHz, with a typical loss of -2dB. When the switch is turned off, how-ever, it behaves like a capacitor, and off-isolation decreases with increasing frequency. (Above 300MHz,the switch actually passes more signal turned off than turned on.) This effect is more pronounced with higher source and load impedances.Figure 1.

Switching-Time Test CircuitAbove 5MHz, circuit board layout becomes critical,and it becomes difficult to characterize the response of the switch independent of the circuit. The graphs shown in the Typical Operating Characteristics were taken using a 50Ωsource and load connected with BNC connectors to a circuit board deemed “average,”that is, designed with isolation in mind, but not using stripline or other special RF circuit techniques. For criti-cal applications above 5MHz, use the MAX440,MAX441, and MAX442, which are fully characterized up to 160MHz.Figure 3.
