Format of Warning Indications** Indicates a potentially hazardous situation **CAUTION** which, if not avoided, may result in minor or moderate injury or in property damage. **Precautions for** Indicates supplementary comments on what to do or avoid doing, to use the **Safe Use** product safety. Includes operating precautions to ensure **Precautions for** that the product will operate properly and **Correct Use** that performance and functions will not be adversely affected. ## **Meaning of Graphic Symbols for Ensuring Product Safety** ## **Precautions for Safe Use** - Rapid changes in temperature or high humidity may cause condensation in Timer circuits, possibly resulting in malfunction or damage to components. Check the application environment. - Use the Timer within the ambient operating temperature and ambient operating humidity ranges given for the Timer model you are using. - Do not use or store a Timer in the following locations. - Locations subject to water, oil, or chemicals - Outdoor locations or under direct sunlight - Locations subject to dust or corrosive gases (sulfurizing gases, ammonia, chloride gas, silicon gas, etc.) - Locations subject to vibration and large shocks **==> picture [34 x 103] intentionally omitted <==** Indicates the possibility of electric shock under specific conditions. Indicates the instructions of unspecified prohibited action. Indicates the possibility of injuries, such as electric shock by disassembling the device, prohibiting disassembly. Indicates the instructions of unspecified general action. - Locations subject to wind and rain - Locations subject to insects or small animals - Each switch has a snap mechanism that secures the switch at given positions. Set each switch to one of these positions. Do not set a switch midway between two positions. Malfunction or failure could result from an improper setting. - Separate the Timer from any sources of excessive static electricity, such as forming materials and pipes carrying power or liquid materials. - Maintain the variations in the power supply voltage to within the specified allowable range. - If a voltage that exceeds the rating is applied, internal components may be destroyed. - The terminal block may be damaged if you insert a screwdriver in the release hole with excessive force. ## **CAUTION** **Switching arcs or relay heating may cause fire or explosion. Do not use the Timer in the presence of inflammable or explosive gases.** **The H3DT Series uses a transformerless power supply system. An electrical shock may occur if an input terminal is touched while power is being supplied.** - Do not wire anything to the release holes. - Do not tilt or twist a flat-blade screwdriver while it is inserted into a release hole on the terminal block. The terminal block may be damaged. - Insert a flat-blade screwdriver into the release holes at an angle. The terminal block may be damaged if you insert the screwdriver straight in. - Do not allow the flat-blade screwdriver to fall out while it is inserted into a release hole. - Do not bend a wire past its natural bending radius or pull on it with excessive force. Doing so may cause the wire disconnection. - Do not insert more than one wire into each terminal insertion hole. **The inrush current will depend on the type of load and may influence the contact switching frequency and number of operations. Check both the rated current and the inrush current, and allow leeway in the circuit design.** **The life of the output relay largely depends on the switching current and other switch conditions. Consider the actual application conditions and do not exceed the rated load or electrical life. If the output relay is used beyond its service life, the contacts may fuse or burning may occur. Also, never exceed the rated load current. When using a heater, also place a thermal switch in the load circuit.** **Do not remove the external case.** **Minor electric shock, fire, or equipment failure may sometimes occur. Do not disassemble, modify, or repair the Timer or touch any internal parts.** - To prevent wiring materials from smoking or ignition, confirm wire ratings and use the wiring materials given in the following table. **Recommended wire Stripping length** ( **Ferrules not used)** 0.25 to 1.5mm[2] /AWG24 to 16 8 mm - Use only the specified wires for wiring. - When wiring the terminals, allow some leeway in the wire length. - Install and clearly label a switch or circuit breaker so that the operator can quickly turn OFF the power supply. - If the Timer is left in the timed out condition for a long period of time at high temperatures, internal components (such as electrolytic capacitors) may deteriorate quickly. - The exterior of the Timer may be damaged by organic solvents (such as thinners or benzene), strong alkali, or strong acids. - For Timers with AC power input, use a commercial power supply for the power supply voltage. Although some inverters give 50/60 Hz as the output frequency, do not use an inverter output as the power supply for a Timer. Doing so may result in smoking or burning due to internal temperature increases in the Timer. - When disposing of the Timer, observe all local ordinances as they apply. **30** **H3DT** - The Timer may not operate properly in locations that are subject to sulfide gas, such as in sewers or incinerators. Products that are suitable for operation in sulfide gas are not available for OMRON Timers or general control devices. Seal the Timer to isolate it from sulfide gas. If the Timer cannot be sealed, OMRON can make special products with resistance to sulfide gas for some Timers. Ask your OMRON representative for details. - Confirm that the power and output indicators are operating normally. Depending on the operating environment, the indicators and plastic parts may deteriorate faster than expected, causing the indicators to fail. Periodically perform inspections and replacements. ## **Precautions for Correct Use** Be sure you understand the contents of this document and handle the Timers according to the instructions provided. ## **Changing Switch Settings** Do not change the time unit, operating mode, or INIT/ TIME switch while the power is being supplied to the Timer. Doing so may result in malfunction. Turn OFF the power supply before changing the setting of any switch. ## **Mounting and Dismounting** - Although there are no particular mounting restrictions, the Timer should be mounted as horizontally as possible. - To mount the Timer to a DIN Track, hook the Timer onto the DIN Track and press the Timer in the direction of the arrow until you hear it lock into place. **==> picture [14 x 5] intentionally omitted <==** **----- Start of picture text -----**<br> Hook<br>**----- End of picture text -----**<br> ## **Screw Mounting** **1.** Pull out the two hooks on the back of the Timer to the outside until you hear them click in place. **2.** Insert M3 screws into the hook holes and secure the Timer. **==> picture [223 x 116] intentionally omitted <==** **----- Start of picture text -----**<br> Mounting Hole Dimensions<br>(1)<br>Two M3 screw holes or<br>(2) two 3-dia. holes<br>108<br>(1)<br>Note: Pull out the hooks to mount<br>(2) the Relay with screws.<br>**----- End of picture text -----**<br> ## **Power Supply** - The power supply can be connected to the power input terminals without considering polarity. - A DC power supply can be connected if its ripple factor is 20% or less and the average voltage is within the allowable voltage fluctuation range of the Timer. - For the power supply of the input device, use an isolating transformer in which the primary and secondary windings are mutually isolated and the secondary winding is not grounded. (H3DT-N and H3DT-L only) - The H3DT-H has a large inrush current. Provide sufficient power supply capacity. If the power supply capacity is too small, there may be delays in turning ON the output. ## **Relationship between Input and Power Supply Circuits (H3DT-N/L)** **==> picture [15 x 5] intentionally omitted <==** **----- Start of picture text -----**<br> Hook<br>**----- End of picture text -----**<br> - To remove the Timer, insert a screwdriver into the hook on the top or bottom and pull out the hook to release the Timer. **==> picture [107 x 114] intentionally omitted <==** **----- Start of picture text -----**<br> Hook<br>30 mm min.<br>Hook<br>**----- End of picture text -----**<br> **==> picture [138 x 73] intentionally omitted <==** **----- Start of picture text -----**<br> B1 A1<br>AC/DC<br>power supply Input circuit Power supply circuit<br>A2<br>**----- End of picture text -----**<br> - The input circuit and the power supply circuit are configured independently. The input circuit can be turned ON and OFF without considering the ON/OFF state of the power supply. A voltage equivalent to the power supply voltage is also applied to the input circuit. - It will be easier to mount and dismount the Timer if a distance of 30 mm or more is provided between the bottom of the Timer and other equipment. **31** **H3DT** - If a relay or transistor is connected to two or more Timers, the input terminals of those Timers must be wired properly so that they will not be different in phase or the terminals will be short-circuited to one another. Always use the same power supply phases. **==> picture [151 x 293] intentionally omitted <==** **----- Start of picture text -----**<br> Contact or transistor for<br>external input signal<br>A1<br>B1<br>H3DT Power<br>A2<br>A1<br>B1<br>H3DT<br>A2<br>Contact or transistor for<br>external input signal<br>A1<br>B1<br>H3DT Power<br>A2<br>A1<br>B1<br>H3DT<br>A2<br>**----- End of picture text -----**<br> - The power supply circuits for H3DT-series Timers use switching mode. Therefore, if there is a transformer or other device with a large inductance component on the power supply line, the inductance will cause a reverse voltage. If that occurs, insert a CR filter in the power supply line to reduce the reverse voltage. ## **Environment** - When using the Timer in an area with excessive electronic noise, separate the Timer and input device as far as possible from the noise sources. It is also recommended to shield the input signal wiring to prevent electronic interference. - The external impulse voltage entering across the power supply terminals has been checked against a ± 1.2 × 50 μ s standard waveform according to JEC-210, Impulse Voltage/Current Test, of The Institute of Electrical Engineers of Japan. Surge or noise superimposed on the power supply may damage internal components or cause them to malfunction. We recommend that you check the circuit waveform and use surge absorbers. The effects on components depend on the type of surge and noise t ~~ha~~ t are generated. Always perform testing with the actual equipment. - The Timer may be be affected by incoming radio wave interference. Do not use the Timer near radio wave receivers. - Do not use the Timer in circuits with waveform distortion. Error will be large due to waveform distortion. - Do not install the Timer immediately next to heat sources. ## **Wiring** ## **1.

Use the flat-blade screwdriver from below the list. The following table shows manufacturers and models as of 2015/Dec. **==> picture [136 x 77] intentionally omitted <==** **----- Start of picture text -----**<br> Side Front<br>2.5 mm dia.<br>0.4 mm 2.5 mm<br>**----- End of picture text -----**<br> |**Model**|**Manufacturer**| |---|---| |ESD0.40✕2.5|Wera| |SZS 0.4✕2.5<br>SZF 0-0.4×2.5*|Phoenix Contact| |0.4✕2.5✕75 302|Wiha| |AEF.2.5✕75|Facom| |<br>210-719<br>SDI 0.4✕2.5✕75|<br>Wago<br>Weidmuller| - OMRON's exclusive purchase model XW4Z-00B is available to order as SZF 0-0.4×2.5 (manufactured by Phoenix Contact). If you wire crossovers and connect terminal blocks in parallel, a large current will flow. Make sure that the current does not exceed 10 A. - Do not connect anything to unused terminals. - Wire all terminals correctly. - Check all wiring before you turn ON the power supply to the Timer. - The H3DT-H acts like a high-impedance circuit. Therefore, the Timer may not reset if it is influenced by inductive voltage. To eliminate inductive voltage, the wires connected to the Timer must be as short as possible and should not be installed parallel to power lines. If the Timer is influenced by inductive voltage that is 30% or more of the rated voltage, connect a CR filter with a capacitance of approximately 0.1 μ F and a resistance of approximately 120 Ω or a bleeder resistor between the power supply terminals. If there is any residual voltage due to current leakage, connect a bleeder resistor between the power supply terminals. ## **Operating Frequency** - The H3DT-H may malfunction if it is used as shown below. Do not use the H3DT-H in these ways. - Timer Repeatedly Times Out in Cycles of 3 s or Less **==> picture [149 x 38] intentionally omitted <==** **----- Start of picture text -----**<br> 3 s 3 s<br>or less or less<br>Power<br>Output<br>**----- End of picture text -----**<br> In the above case, use the H3DT-N in D mode (signal OFF delay). - If you use Flicker Mode and set the dial on the H3DT-F to the minimum setting, the contacts may be damaged. Avoid this type of application. ## **Options** - Use the Y92A-D1A for the Front Cover. **==> picture [91 x 43] intentionally omitted <==** **----- Start of picture text -----**<br> 8 to 10 mm<br>1.9 mm max.<br>2.6 mm max.<br>**----- End of picture text -----**<br> - If you use the Front Cover, make sure that it is attached securely. **33** **H3DT** ## **Other Precautions** - If the Timer is mounted on a control panel, dismount the Timer from the control panel before carrying out a voltage withstand test between the electric circuits and non-current-carrying metal parts of the Timer. (Otherwise, the internal circuits of the Timer may be damaged.) - The H3DK-H uses a latching relay for the output. Shock, such as dropping the H3DK-H during shipment or handling, can cause the output contacts to reverse to the neutral position. Check the output status with a tester before using the H3DK-H. - The life expectancy of the control output contacts is greatly affected by switching conditions. Always confirm operation using the actual conditions and equipment before using the Timer and make sure that the number of switching operations presents no problems in performance. If Timer application is continued after performance has deteriorated, insulation failure between circuits, burning of the control output relay, or other problem will eventually occur. - If the power supply voltage is gradually increased, a power reset may occur or the Timer may time out. Use a switch, relay, or other device with contacts to apply the power supply voltage all at once. - Make sure that residual voltage or inductive voltage is not applied after the power turns OFF. - Error in the operation time of the Timer is given as a percentage of the full-scale time. The absolute value of the error will not change even if the set time is changed. Therefore, always use the Timer with the set time set as close as possible to the full-scale value of the set time range. - When switching a microload, check the specified minimum load given for the Timer model you are using. - When setting the operating time, do not turn the dial beyond the scale range. - Store the Timer within the rated ranges given for the Timer model you are using. If the Timer is stored below −20°C, allow it to warm up for three hours at room temperature before turning ON the power supply. - Do not install the Timer in any way that would place a load on it. - When cleaning the Timer, do not use thinners or solvents. Use commercial alcohol. - If better accuracy is required in the set time, adjust the dial while measuring the operation time. - Do not construct a circuit for the H3DT-H that would allow overcurrent and burning to occur if the NO, NC and SPDT contacts are short-circuited. Arcing may generate short-circuiting between contacts if there is short-circuiting because of conversion to the MBB contacts caused by asynchronous operation of the NO and NC contacts, the interval between the NO and NC contacts is small, or a large current is left open. - If the Timer is reset immediately after timing out, make sure that the circuit configuration allows sufficient resetting time. Errors will occur in the sequence if there is not sufficient resetting time. - When directly switching a DC load, the switching capacity will be lower than when switching an AC load. ## **EN/IEC Standard Compliance** - Refer to the datasheet for the H3DK for cable selection and other conditions for compliance with EMC standards. ## **Precaution on EN Standard Compliance** The H3DT complies with EN 61812-1 when it is built into a panel, but observe the following handling methods to ensure compliance with the requirements of this standard. ## **Wiring** Overvoltage category III Pollution degree 2 - Open-frame Device - If basic, double, or reinforced insulation is required, use the basic, double, or reinforced insulation defined in IEC 60664 that is suitable for the maximum applied voltage for the clearance, solid insulation, and other factors. - The power supply terminals and input terminals are not isolated from each other. - There is basic insulation between the power supply terminals and output terminals. - There is basic insulation between the input terminals and output terminals. - The operating section must have reinforced or double insulation. - The sides of the case are not isolated. - Connect the output contacts (contacts with different polarity) so that they reach the same potential. **==> picture [232 x 110] intentionally omitted <==** **----- Start of picture text -----**<br> Not isolated<br>Reinforced insulation<br>(or double insulation)<br>**----- End of picture text -----**<br> ## **Recommended Replacement Periods and Periodic Replacement as Preventive Maintenance** The recommended replacement period for preventive maintenance is greatly influenced by the application environment of the product. As a guideline for models that do not have a Maintenance Forecast Monitor, the recommended replacement period is 7 to 10 years. * To prevent failures that can be caused by using a product beyond its service live, we recommend that you replace the product as early as possible within the recommended replacement period. However, realize that the recommended replacement period is for reference only and does not guarantee the life of the product. Many electronic components are used in the product and the product depends on the correct operation of these components to achieve product functions and performance. However, the influence of the ambient temperature on aluminum electrolytic capacitors is large, and the service life is reduced by half for each 10°C rise in temperature (Arrhenius law). When the capacity reduction life of the electrolytic capacitor is reached, the product may fail. We therefore recommend that you replace the product periodically to minimize product failures in advance. - The following conditions apply: rated input voltage, load rate of 50% max., ambient temperature of 35°C max., and the standalone mounting method. This product model is designed with a service life of 10 years minimum under the above conditions. **34** ## **Terms and Conditions Agreement** ## **Read and understand this catalog.** Please read and understand this catalog before purchasing the products.
