Technical Explanation for Timers and Time Switches CSM_Timer_Timeswitch_TG_E_7_3 Introduction Sensors What Is a Timer? A Timer is a control device that outputs a signal at a preset time after an input signal is received. Timer Mechanisms Switches (3) Timing Section Output Section (4) Output Section Power Supply Section Operating Modes of Timers Example for the H3CR-A (1) (5) (1) Time setting knob (2) Time unit selector (3) Time range selector (4) Operating mode selector (2) The following four basic operating modes are the most commonly used. ON-delay Operation (Mode A) OFF-delay Operation (Mode D) Operation Modes Power Supplies / In Addition Flicker Operation (Mode B) Interval Operation (Mode E) Others Indications The pointers on the Timer do not move along with time like the hands of a clock do. You cannot see the progression of time. Therefore, two operation indicators are provided on the upper left of the Timer to identify the timer status. (5) Run/Power Indicator (Green) Run indicator: Indicates whether the time is being measured or the time has reached. Power indicator: Indicates whether power is being supplied to the Timer. Fundamentally, the indicators will be lit when the power is being supplied. However, they will flash when the time is being measured. (6) Output Indicator (Orange) Used to see the status of the output. Lit when a signal is output. The operating mode determines the output method that is used when the set time has reached. Energy Conservation Support / Environment Measure Equipment A variety of time ranges can be set with the H3CR-A using Note the time unit selector and time range selector. Motion / Drives (3) (4) Automation Systems The operating mode selector is in the upper-right corner on the H3CR-A. Settings (6) Outputs signals to output devices. Control Components Settings and Indications of Timers Relays (1) Power Supply Section Supplies the applied voltage to the internal components. Timing Section Receives signals from input devices and outputs the signals to the timing section. Input Section (2) Input Section Safety Components Measures the time and outputs a signal to the output section at specified time. Common 1 Technical Explanation for Timers and Time Switches Flicker Operation ON-delay Operation Sensors Input Input Time counted out Output t After t seconds t t t t t t t t Output Switches With flicker operation, an output repeatedly turns ON and OFF at the set time after an input is received. Application: Automatic Control of Fountains Safety Components With ON-delay operation, the Timer receives an input and then an output signal is output by switching the Timer contacts after a set time delay. This name is used because there is a delay between when the input signal is received (i.e., turns ON) and when the output signal is output. ON-delay operation is the operating mode most often used for automated machines. Relays The water is repeatedly released and stopped at intervals of two minutes. Application: Pushbutton Signals When the pedestrian pushbutton is pressed for a traffic signal, the signal light changes from red to green after a delay. Control Components Interval Operation Input Automation Systems OFF-delay Operation t Output Input Time counted out t seconds Application: Amusement Park Rides Motion / Drives Output With interval operation, the output turns ON at the same time as the input and the output turns OFF after a set time. The ride operates for five minutes when 100 yen is inserted. Power Supplies / In Addition Application: Car Ceiling Lights When you get in your car, the ceiling light turns ON when the door is opened. The light remains lit for several seconds after you get into the car and close the door. Energy Conservation Support / Environment Measure Equipment With OFF-delay operation, the output turns ON at the same time as the input and then the output turns OFF when the Timer contacts switch after the set time has expired. The set time is calculated from when the input turns OFF. This name is used because there is a delay between when the input turns OFF and when the output turns OFF. Others Common 2 Technical Explanation for Timers and Time Switches Timer Starting Methods Sensors There are two starting methods for the operating modes. Power ON-delay Safety Components Signal ON-delay Switches Example: ON-delay Operation Signal ON-delay operation: Measuring time starts when the input section receives an input while voltage is being applied to the Timer power supply section. Power ON-delay operation: Measuring time starts when voltage is applied to the Timer power supply section. Power supply Power supply Input Output t Output t Relays Control Components Differences between Signal ON-delay Operation and Power ON-delay Operation (1) Accuracy* Operation will not be stable unless a brief period elapses after the power supply is turned ON to the timing section of the Timer. Power supply start:Operation is unstable because measuring time starts at the same time that the power supply turns ON. Therefore, deviation will occur in the operation time immediately after starting the Timer. Signal start: Stable time accuracy is ensured because a voltage is already applied to the Timer before starting the Timer. The accuracy of the signal start is generally considered better. For some models, however, such as the H3CR, there is no change in accuracy. Automation Systems Motion / Drives *Accuracy is the correctness of the time. Power supply start (H3CR-A8) Power Supplies / In Addition Gate input Reset input Start input Signal start (H3CR-A) Energy Conservation Support / Environment Measure Equipment (2) Terminal Arrangement Power supply Power supply Others • Models with a signal start require three external inputs, so they have many terminals. • Models with a power supply start (H3CR-A8) are the H3CR Timers most often used for automated machinery. Common 3 Technical Explanation for Timers and Time Switches What Is a Time Switch? Sensors A Time Switch is a control device that turns a load ON and OFF at the set times. Time Switch Mechanisms Switches (3) Timing Section Output Section Input Section Receives signals from input devices. Safety Components (2) Input Section Timing Section Measures the time and outputs a signal to the output section at specified time. (4) Output Section Outputs signals to output devices. Power Supply Section Relays (1) Power Supply Section Supplies the applied voltage to the internal components. Control Components However, most models of Time Switches do not have an input section. If there is an input section, it is not used to output signals to the timing section, rather, it is used to control some of the functions of the Time Switch, such as adjusting the time.

Power Supplies / In Addition Pulse-output Operation Pulse width Others ON time With pulse-output operation, the Time Switch outputs a pulse of a specified time width at the set ON time. Common 5 Technical Explanation for Timers and Time Switches Override and Automatic Return Operation With a Time Switch, the progression of time starts when a voltage is applied to the power supply section. * When the power supply section is OFF, time progresses and the settings are retained, but no operations are performed to turn the output ON or OFF. Terminal Arrangement Example for the H5F-A/B Switches Regular program Time Switch Starting Methods Sensors Forced ON/OFF Operation Forced ON/OFF Operation is used to force the output ON or OFF by using the output ON/OFF switch regardless of the control output setting. Power supply: 100 to 240 VAC Output operation Safety Components Start of override and automatic return operation With override and automatic return operation, the output ON/ OFF switch and the Write Key are used to hold the control output ON until the next OFF time. Partial Operation on Specified Day Load Load power supply Relays Program 1 Program 2 (special) Regular program Control Components Operation on operation day Operation on specified day You can select days on which to execute only part of the set operations. Automation Systems Holiday Setting Operation on Operation on operation day holiday Regular program Motion / Drives Operation in present week Operation from next week Energy Conservation Support / Environment Measure Equipment It is possible to set an operation day in the present week as a holiday (i.e., a non-operation day: output will be OFF regardless of the settings). When that day has passed, operation will continue according to the regular program, and operation will be executed as normal on that day from the following week. Power Supplies / In Addition Others Common 6 Technical Explanation for Timers and Time Switches Explanation of Terms Accuracy of Operating Time The period of time during which the specified voltage is applied to the operating circuit. The difference in operating times measured when the Timer repeats operation under the same conditions with a specified set time. OFF Time Operating Time Holding Time The period of time from the completion of the time-limit operation to the start of the reset operation. where, T max.: Maximum value of operating times measured at the same set time T min.: Minimum value of operating times measured at the same set time TMs: Maximum scale time (TMs is a set value in the case of a Digital Timer.) Safety Components The period of time from the application of the specified voltage to the operation circuit until the completion of the time-limit contact operation. Formula for calculation (with operating time measured more than 5 times): Accuracy of operating time=± 1 × Tmax−Tmin ×100 (%) 2 TMs Switches The period of time between the moment that resetting begins and the moment that the operating voltage is applied to the operating circuit again. The OFF time is longer than the resetting time. Sensors ON Time The difference in the operating times appears as a shift from the central value of operation, so the maximum or minimum values divided by 2 and expressed as plus (+) and minus (-) indication. Resetting Time Tmax OFF time Operating circuit (= power supply) Time-limit SPST-NO contacts SPST-NC Tmin If the settings of an Analog Timer is changed while it is performing time-limit operation, the following operation will result. T3−T1 T=T1+T2× T3 Internal mechanism Internal circuit Operating time Holding Resetting time time Setting Error The difference between the actual operating time and scale time. Formula for calculation (measurement position can be any scale position as long as it is set to 1/3 min. of the maximum scale time): TM−Ts Setting error= ×100 (%) TMs For a Time Switch, the setting error is applied for the pulseoutput operating time. A single time rating that combines the setting error, accuracy of operating time, influence of temperature, and influence of voltage. This rating applies to all measurement results for measurements made under the setting error, influence of temperature, and influence of voltage conditions. Power Supplies / In Addition Total Error (Time Switch) To Automatically reset the Timer by interrupting the voltage that is supplied to the operating circuit. To reset the Timer by applying the required voltage to the reset circuit. Energy Conservation Support / Environment Measure Equipment TM: Average value of five or more measured operating times Ts: Set time TMs: Maximum scale time (TMs is a set value in the case of a Digital Timer.) Self-reset Electrical Reset Motion / Drives The resetting time of the Timer is the period of time during which all the internal components including the contacts, pointer, and the circuit components, such as the capacitor, of the Timer are reset. If the Timer is operated with an insufficient OFF time (i.e., the OFF time is less than the rated resetting time), the normal operation of the Timer cannot be expected. In such cases, the Timer may operate with an insufficient operating time, operate instantaneously, or not operate at all. Be sure that the OFF time of the Timer is the same as or more than the rated resetting time. Final time-up time Time elapsed New setting Previous setting Automation Systems T: T1 : T2 : T3 : Control Components ON time Relays The period of time from the interruption of the voltage supplied to the operating circuit during or after the time-limit operation until the return of the Timer to its initial state. Central value (T) Cyclic Error (Error per Month) (Time Switches) Others The error time in the internal clock per month at an ambient temperature of 25°C. Common 7 Technical Explanation for Timers and Time Switches Vibration Resistance (Malfunction) The change in the operating time when the voltage of the control power source changes within the allowable voltage range. Formula for calculation: Variation due to voltage change TMx1−TM1 =± ×100 (%) TMs The range of vibration during operation in which contacts that are closed will not open by vibration for at least the specified time (1 ms). OFF Time Characteristics Insulation Resistance The resistance provided by an electrically insulating material between charged metal parts and uncharged metal parts, between control outputs and operating circuits, etc. Dielectric Strength The voltage level that will not cause insulation breakdown when applied for 1 minute to the same location as in the insulation resistance measurement. Impulse Withstand Voltage (AC) A voltage imposed between the operating power supply terminals or between a charged terminal and non-charged metal part to test the resistance to surge voltages. The impulse withstand voltage 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 ±1.2 × 50-μs standard waveform. Noise Immunity The malfunction and destruction resistance of the Timer against external noise. The noise immunity of the Timer is checked with a noise simulator, an inductive load, an oscillating relay, and static electric noise. Energy Conservation Support / Environment Measure Equipment Mechanical Life Expectancy The life expectancy of a Timer when the control output of the Timer is operated under a no-load condition. Power Supplies / In Addition The OFF time characteristics are determined by the charging and discharging of a capacitor and resistor used in combination as an Electronic Timer. The characteristics vary from ±1.5% to ±5%. The accuracy of operating time, setting error, influence of voltage, influence of temperature, and OFF time characteristic are used to express the precision of the Timer. Any of these items may be ignored depending on the particular specifications of the model. The Motor Timer and Electric Timer indicate these items by percentage values. The Count Timer indicates these items by differential time values because the differential range of the Timer's operating time is essentially constant due to operating principles of the Timer. Furthermore, the total error can be indicated to express all these items in the case of the Count Timer. The range of shock in which there is no damage to parts during transport or use, and the operating characteristics are still satisfied. Motion / Drives TM3: Average value of operating times measured with a 1-second OFF time. TMx3: Average value of operating times measured with an OFF time that causes the maximum deviation from TM3 within the specified OFF-time range of one hour from the specified resetting time. TMs: Maximum scale time (TMs is a set value in the case of a Digital Timer.) Shock Resistance (Destruction) Automation Systems The change between the operating time for a given OFF time and the operating time when the OFF time is changed. Formula for calculation: OFF time characteristic TMx3−TM3 =± ×100 (%) TMs The range of shock during operation in which contacts that are closed will not open by shock for at least the specified time (1 ms). Control Components where, TM2: Average value of operating times measured at 20°C. TMx2: Average value of operating times measured at the temperature that causes the largest deviation from TM2 within the ambient operating temperature range. TMs: Maximum scale time (TMs is a set value in the case of a Digital Timer.) Shock Resistance (Malfunction) Relays The change in the operating time when the ambient temperature changes within the ambient operating temperature range. Formula for calculation: Variation due to temperature change TMx2−TM2 =± ×100 (%) TMs The range of vibration in which there is no damage to parts during transport or use, and the operating characteristics are still satisfied. Safety Components Influence of Temperature Vibration Resistance (Destruction) Switches where, TM1: Average value of operating times measured at rated power supply voltage TMx1: Average value of operating times measured at the voltage that causes the largest deviation from TM1 within the allowable voltage range. TMs: Maximum scale time (TMs is a set value in the case of a Digital Timer.) Sensors Influence of Voltage Electrical Life Expectancy Others The life expectancy of a Timer when the control output of the Timer is operated to switch the specified voltage/current load connected to the control output. The electrical or mechanical life of the Timer is generally indicated by the operating times of the control output. The electrical life is indicated by the operating times of the control output connected to a load and the mechanical life is indicated by the operating times 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 Timer, use the Timer to switch heavy loads via relays instead of directly switching them with the control output.

Troubleshooting Problem The inrush current when the power supply voltage was applied may have damaged the sensor output. The top part of the display on a Timer with a memory backup is missing. If the power supply is not connected and power is interrupted for 10 minutes or longer, the measured value or display will not be dependable and unnecessary outputs may appear. Always connect a battery when you use a Timer with a memory backup. If the battery voltage is 3 V, you can use various type of batteries. The memory backup time will depend on the capacity of the battery. Timers Switches Solution Use an MY or other relay to turn the power supply to the Timer ON/OFF. (Use a suitable contact capacity.) Sensors Probable cause A sensor was used to turn the power supply to the Timer ON and OFF, but the sensor output was damaged.
