HR-41 has function s, which means that only upper level is set ( Uma) and lower level (Umin) is set in % from upper level. Therefore lower level automatically changes when changing upper level. HR-4 has function WIDOW, which means that upper level (Uma) and lower level (Umin) are set independently in % from rated monitores range. Both types have choice of function MEMORY, in case the relay gets into a faulty state it keeps output in this state until it is reset by button RESET. DIP switch o.3 can be used to choose if relays should switch individually for each level or in parallel in case level of voltage is overrun. DIP switch o.4 serves to set hysteresis which applies when going from normal state to a faulty one. Relay has protection against polarity reversing for DC voltage or incorrectly chosen AC-DC voltage (this fault is indicated by flashing of both EDs ( ED <U a ED >U). MEMORY-O (DIP) 65

ED - green indicator light ED U - red indicator light Monitoring relay series HR-3 monitors level of voltage in single - phase circuits. Monitored voltage serves also as supply voltage. It is possible to set two indipendent (all occurrences) levels of voltage, when eceeded the output is activated. HR-33 and HR-34 - in normal state the output relay is permanently switched. It switches off when there is a limit settings. This combination of linkage of the output relay is advantageous when the full failure of supply (monitored) voltage is considered to be a faulty state in the same way as a decrease of voltage within the set level. relay is in both situations always switched off. Differently HR-35 version uses indipendent relay for each level, in normal state it is switched off. If the upper level is eceeded (for eample overvoltage) 1 relay switches on, when the bottom level (e.g. undervoltage) is eceeded relay switches. It is thus possible to see the particular faulty state. To eliminate short peaks in the main the time delay, which is possible to be set in range 0-10 s, is used. It functions when changing from normal to faulty state and prevents unavailing pulsation of the output relay caused by parasitive peaks. Time delay doesn t apply when changing from faulty to normal state, but hysteresis (1-6% depends on the voltage setting) apply. Thanks to changeover contacts it is possible to get other configurations and functions according to actual requirements of the application. HR-63, 64, 67 (over/under voltage relay) HR-63, 64, 67 egend: Uma - upper adjustable level of voltage - measured voltage Umin - bottom adjustable level of voltage - switching contact of output relay ED U> - red indicator light Monitoring relay line HR-6 serves to monitor levels of voltage in single-phase or DC circuits. Monitored voltage is in the same time also supply voltage. It is possible to set two indipendent levels of voltage. When Uma is eceeded, output is activated. In case voltage level falls below Umin, output is deactivated. This combination is advantageous when full absence of supply voltage is understood as faulty state, as well as voltage drop within the set level. To eliminate short voltage peaks in the main there is time delay which can be set in a range of 0-10 sec. Such delay applies in case of going from overvoltage to undervoltage. In case of returning from undervoltage to overvoltage this delay doesn t apply. Thanks to changeover output contacts it is possible to reach various configurations and functions according to requirements or an application. 67

Type HR-43 controls voltage towards neutral wire, type HR-43 controls interphase voltage. Relay can monitor voltage in two levels (overvoltage/ undervoltage), phase assymetry, sequence and failure. Each faulty state is indicated by individual ED. By DIP switch (o.3) it is possible to define function of the other relay independent function (1 for overvoltage, 1 for undervoltage) or in parallel. Time delays t1(fied) when changing from faulty to normal state or when de-energized and t (adjustable) when changing from normal to faulty state. These delays prevent incorrect conduct and oscillation of output device during short voltage peaks in the main or during gradual voltage decline into normal. Voltage control Set upper level Uma in range V (or V for HR-43) and lower level Umin in range 35-99% Uma. In case phase passes this range, after a delay which eliminated short voltage peaks, contact opens. contact again switches after returning back into monitored voltage range and eceeding fied hysteresis (which is adjustable in two values by DIP switch). Phase sequence Monitors correctness of phase sequence. In case of unwanted change output contact breaks. In case of energization of a device with incorrect phase sequence, contact stays opened. Asymmetry Rate of assymetry between individual phases is set in a range of 5-0%. In case set asymmetry is eceeded, output relay breaks and ED indicating asymmetry shines. Delays t1, t and hysteretic are applicable when returning to normal state. 73

To prevent polarization and liquid electrolysis of liquid, and undesirable oidation of measuring probes, alternating current is used. For measuring use three measuring probes: H- upper level, D- lower level, C - common probe. In case you use a tank made of a conductive material, you can use it as probe C. In case you require monitoring of one level only, it is neccessary to connect inputs H and D and connect them to one probe - in this case sensitivity is lowered by half ( kΩ). Probe C can be connected with a protective wire of supply system (PE). To prevent undesirable switching out output contacts by various influences (sediment on probes, humidity...) it is possible to set sensitivity of the device according to conductivity of monitored liguid (corresponding to resistance of liquid) range 5 up to 100kΩ. To reduce infuences of undesirable switching of output contacts by liquid gorgle in tanks, it is possible to set delay of output reaction s. 83

In this principle, it goes on about the measurement of liquids by measuring probes. As the measuring used signal is 5V AC/ 500Hz. Using an AC signal prevents the the increasing oidation of probes and unwanted polarization and electrolysis liquid. During depending on the DIP settings configurations, switches can control two independent levels or use a combined function for one level (see diagram of functions). The relay is equipped with regulation of the sensitivity to to liquid resistance. It s also possible to eliminate some of the unwanted switching in the sensitivity settings according to specific conditions (for eample, pollution probe sediments, humidity, etc.). It s also possible for each probe to set the delay in the range of s, and using the DIP switch type delay (when you turn the relay on and off, depending on application).

Thus it is possible to use e.g. first thermostat as operational and the other as an emergency one. 5-8 operates normally, according to T. This device includes thermostats in one. Thermostat has thermo inputs, outputs and individual temperature setting. It offers two possibilities of use. Firstly it can be used as two individual thermostats (e.g. for monitoring two temperature levels of one device or as a control of individual devices), secondly it is possible to set depending function of both thermostats, when thermostat blocks thermostat o.1 Advantage of this thermostats is a wide temperature range C (in one device) with very good mechanical accuracy of setting. It is due to 10-state switch for thermo ranges and its scale by C(59 F). VIt is possible to use fine tuning by potentiometer by 0- C(3-59 F) with accuracy ±1 C/ 34 F. Device has in-built control of sensor fault ( yellow ED). It is possible to set hysteresis 0.5 or.5 C (3.9 or 37 F). It is possible to operate the thermostat only with one sensor. In that case it is necessary to connect a resistor 10 kω to the other input. This is included in the package. H H1 H H1

By temperature increase the resistance goes strongly up and by overrun the limit of 3.3 kω the contact of output relay switch off - mostly contactor controlling a motor. By temperature decrease and thereby decrease of thermistor resistance under 1.8 kω the output contact of relay again switches on. The relay has function Control of sensor fault. This controls interruption or disconnection of sensor.when switch is in position TK monitoring of faulty sensor is not functional - it is possibel to connect bimetal sensor with only states: O or OFF.

Switching of output corresponds with input, which has lower temperatures when diffference is eceeded. Differencial thermostat is used for keeping two identical temperature e.g. in heating systems (boiler and reservoir), solar systems (collector - reservoir, echanger), water heating (water heater, water distribution)etc. Typical eample of use for two-stage thermostat is e.g in boiler-room, where there are two biolers from which one is main and the other one is auiliary. The main boiler is managed according to set temperature and auiliary boiler is switched in case temperature falls under set difference. Thus it helps to the main boiler in case outside temperature dramatically falls. In the range of set difference (D) output functions as normal thermostat to input 1 (type 1).

If temperature is out of range, the contact opens. T is set as T1-D. The function is used for protection of gutters against freezing. In case of thermostat with a dead zone, it is possible to set temperature T1 and a diff erence (respectively a width of dead zone D). If temperature is higher than T1, output contact of cooling switches O; if the temperature gets bellow T1, the contact switches OFF. If the temperature gets bellow temperature T, the contact of heating switches O and it switches OFF when temperature T is eceeded. This function can be used for eample for automatic air warming and cooling in ventilation so the sit is always within the range T1 and T. 99
