Do not use the Timer in the presence of inflammable or explosive gases.** **The H3DK Series uses a transformerless power supply system. An electrical shock may occur if an input terminal is touched while power is being supplied.** **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.** ## **Precautions for Safe Use** - Use ferrules to wire the H3DK. If stranded wires are used, wire scraps may enter the Timer, possibly shorting the circuits. - 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. - 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. - Use the Timer within the ambient operating temperature and ambient operating humidity ranges given for the Timer model you are using. - Use the Time within the characteristics for water and oil exposure given for the Timer model you are using. - Do not use the Timer in locations subject to excessive dust, corrosive gas, or direct sunlight. - Do not use the Timer in locations subject to vibration and shock. Long-term exposure may damage the Timer due to stress. - 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. - Wire all terminals correctly. - Use only the specified wires for wiring. Applicable wire gauge: AWG18 to AWG22 **Minor electric shock, fire, or equipment failure may sometimes occur. Do not disassemble, modify, or repair the Timer or touch any internal parts.** - 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. - Use the same type of wiring for all Timer wiring. - When disposing of the Timer, observe all local ordinances as they apply. - 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. **25** **H3DK** ## **Precautions for Correct Use** ## ● **Changing Switch Settings** Do not change the time unit, time scale, operating mode, or INIT/ TIME switch while the Timer is in operation. 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. - When mounting the Timer on a mounting Track, loosen the two hooks, press the Timer onto the Track, and then insert the hooks. **==> picture [65 x 88] intentionally omitted <==** **----- Start of picture text -----**<br> Hook<br>Hook<br>**----- End of picture text -----**<br> - When removing the Timer, pull out the two hooks, and then remove the Timer from the Track **==> picture [99 x 102] intentionally omitted <==** **----- Start of picture text -----**<br> Hook<br>30 mm min.<br>Hook<br>**----- End of picture text -----**<br> - 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. ## ● **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. (H3DK-M1 and H3DK-M2 only) **==> picture [122 x 116] intentionally omitted <==** **----- Start of picture text -----**<br> A1<br>B1<br>H3DK Power<br>Start<br>input<br>A2<br>Circuit<br>Isolation transformer is required.<br>Rectifier circuit<br>**----- End of picture text -----**<br> - The H3DK-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 (H3DK-M1/-M2)** **==> picture [138 x 72] 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. - 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 shortcircuited to one another. Always use the same power supply phases. **==> picture [150 x 294] intentionally omitted <==** **----- Start of picture text -----**<br> Contact or transistor for<br>external input signal<br>A1<br>B1<br>H3DK Power<br>A2<br>A1<br>B1<br>H3DK<br>A2<br>Contact or transistor for<br>external input signal<br>A1<br>B1<br>H3DK Power<br>A2<br>A1<br>B1<br>H3DK<br>A2<br>**----- End of picture text -----**<br> ## ● **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 μs 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 that are generated. Always perform testing with the actual equipment. **26** **H3DK** ## ● **Wiring** - Do not connect anything to unused terminals. - The H3DK-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 μF 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 H3DK-H may malfunction if it is used as shown below. Do not use the H3DK-H in these ways. Timer Repeatedly Times Out in Cycles of 3 s or Less |Power<br>Output||3 s<br>|3 s<br>|3 s<br>|3 s<br>|| |---|---|---|---|---|---|---| |||or less||or less||| |||||||| |||||||| |||||||| In the above case, use the H3DK-M2/-M1 in D mode (signal OFF delay). ## ● **DC Power Consumptions (Reference Information)** |H3DK-M2/-S2|At 24 VDC: 1.2 W max.| |---|---| |H3DK-M1/-S1|At 24 VDC: 1.1 W max.| |H3DK-F|At 24 VDC: 1.1 W max.| |H3DK-G|At 24 VDC: 1.2 W max.| |H3DK-HBS/-HBL|At 24 VDC: 1.2 W max.| ## ● **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 ## **EN/IEC Standard Compliance** - Refer to the datasheet for the H3DK for cable selection and other conditions for compliance with EMC standards. - The power supply terminals and input terminals are not isolated. There is basic insulation between the power supply terminals and output terminals. - If double or reinforced insulation is required, use the double or reinforced insulation defined in IEC 60664 that is suitable for the maximum applied voltage for the clearance, solid insulation, and other factors. 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 H3DKH. - 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. - If better accuracy is required in the set time, adjust the dial while measuring the operation time. - 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. ## **Precautions for Compliance with UL Standards and CSA Standards** Notice to Users of the H3DK in the USA and Canada Please use the following installation information instead of the general information in this document in order to use the product under certified conditions of UL and CSA when the product is installed in the USA or Canada.
