1 r Glossary Term Definitions ON The period of during which a required is being applied to the operating circuit. OFF The period of between the moment that begins and the moment that the operating is applied to the operating circuit. Therefore, the OFF of the r is larger than the. Operating The period of from the application of a required to the operating circuit until the completion of the -limit contact operation. Holding The period of from the completion of the -limit operation to the start of the reset operation. Resetting The period of from the interruption of the supplied to the operating circuit during or after the -limit operation until the return of the r to its initial state. The of the r is the period of during which all the internal components including the, pointer, and the circuit components, such as the capacitor, of the r are reset. If the r is in operation with an insufficient OFF (i.e., the OFF is less than the rated ), the normal operation of the r cannot be expected. In such cases, the r may operate with insufficient operating, operate instantaneously, or not operate at all. e sure that the OFF of the r is the same as or more than the rated. Self-reset Operating circuit (= Power source) -limit SPST-NO contact SPST-NC Internal mechanism Internal circuit To automatically reset the r by interrupting the being supplied to the operating circuit. Electrical Reset To reset r by applying a required to the reset circuit. Manual Reset ON Operating OFF Holding Resetting To mechanically reset the r by manual operation. Synchronous Motor ( Switch) motor that operates in synchronization with the power frequency (50/60 Hz). ecause of the simplicity of a structure using this type of motor, it is reasonably priced. The motor stops when there is a power interruption, so the must be reset after the power is restored. Quartz Motor ( Switch) The motor is operated by quartz oscillation. The quartz motor is equipped with a corrective function for power interruptions, so it can be used immediately after the power is restored. ccuracy of Operating Differences of operating s measured when the r repeats operation under the same condition with a given setting. Formula for calculation (with operating measured more than 5s): ccuracy of operating 1 T max. T min. = ± 100 (%) 2 T max.:maximum value of operating s measured at the same set T min.: Minimum value of operating s measured at the same set : Maximum scale ( is a set value in the case of a Digital r) Differences in the operating appear as a shift from the central value of the operation, so the maximum or minimum value is divided by 2 and expressed as a plus (+) or minus ( ) indication. If there are setting changes in the H3C or other types of nalog r while they are in -limit operation, the following operation will result. T = T 1 + T 2 T 3 T 1 T 3 T: Final -up T 1 : elapsed T 2 : New setting T 3 : Previous setting Setting Error difference between the actual operating and scale. Formula for calculation (measurement position can be any scale position as long as it is set to 1/3 min. of the maximum scale ): Setting error = 100 (%) TM Ts T min. T max.

2 Influence of change in operating when the of the control power source changes within the permissible fluctuation range. Variation due to change TMx 1 TM 1 TM 1 : verage value of operating s measured at rated TMx 2 : verage value of operating s measured at a which causes the maximum deviation from TM 1 within the permissible fluctuation range. : Maximum scale ( is a set value in the case of the Digital r.) Influence of Temperature change in operating when the ambient temperature changes within a permissible range. Variation due to temperature change TMx 2 TM 2 TM 2 : verage value of operating s measured at 20 C. TMx 2 : verage value of operating s measured at a temperature which causes the maximum deviation from TM 2 within the specified ambient temperature range. : Maximum scale ( is a set value in the case of the Digital r.) OFF Characteristics change in operating when the operating in a given OFF and the OFF are changed. OFF characteristic TMX3 TM 3 TM 3 : verage value of operating s measured with a 1-second OFF. TMx 3 : verage value of operating s measured with an OFF that causes the maximum deviation from TMx 3 within the specified OFF- range of one hour from the specified. : Maximum scale ( is a set value in the case of the Digital r.) OFF- characteristics are determined by the charging and discharging of a capacitor and resistor used in combination as an Electronic r. The characteristics vary by ±1.5% to ±5%. Operating accuracy, setting error, influence of, influence of temperature, and OFF- characteristics are items used to express the precision of the r. ny of these items may be ignored depending on the particular specifications of the model. The Motor r and Electronic r indicate these items by percentage values. The Count r indicates these items by differential values because the differential range of the r s operating is almost definite due to the operating principle of the r. Furthermore, the Count r total setting error can be indicated to express all these items in the case of the Count r. Vibration Resistance (Malfunction) The range of vibration during operation in which that are closed will not open by vibration for a period exceeding the specified (1 ms). Vibration Resistance (Destruction) The range of vibration in which there is no damage to parts during transport or use, and the operating characteristics are still satisfied. Shock Resistance (Malfunction) The range of shock during operation in which that are closed will not open by shock for a period exceeding the specified (1 ms). Shock Resistance (Destruction) The range of shock in which there is no damage to parts during transport or use, and the operating characteristics are still satisfied. Insulation Resistance The resistance offered by an insulating material to the flow of resulting from an impressed DC. Dielectric Strength The level that will not cause insulation breakdown when applied for 1 minute to the same location as in the insulation resistance measurement. Impulse Withstand (C) imposed between the operating power supply terminals or between a charged terminal and non-charged metal part to check the withstand surge of the r. The impulse withstand imposed between the operating power supply terminals is 3 kv and that imposed between a charged terminal and non-charged metal part is 4.5 kv with both using a ± μs standard waveform. Noise Immunity The mechanical and physical resistance of the r against external noise. The noise resistance of the r is checked with a noise simulator, a coil load, an oscillating relay, and static electric noise. Mechanical Life Expectancy The life expectancy of a r when the control output of the r is operated under no load condition. Electrical Life Expectancy The life expectancy of a r when the control output of the r is operated to switch the specified / load connected to the control output. The electrical or mechanical life of the r is generally indicated by the operating s of control output. The electrical life is indicated by the operating of the control output connected to a load and the mechanical life is indicated by the operating of the control output with no load. The electrical life is shorter than the mechanical life. The lighter the load is, the longer the electrical life will be. Therefore, to prolong the electrical life of the r, use the r to switch heavy loads via relays instead of directly switching them with the control output. 5
