Note: The following precautions apply to all H3CR-A models. Power Supplies Input/Output For the power supply of an input device of the H3CR-A use an isolating transformer with the primary and secondary windings mutually isolated and the secondary winding not grounded. Correct H3CR-A G, S, R 5, 6, 7 10 Input terminal 2 Power supply 2 Relationship between Input and Power Supply Circuits (except for H3CR-A8E) The H3CR-A (except for H3CR-A8E) uses transformerless power supply. When connecting a relay or transistor as an external signal input device, pay attention to the following points to prevent shortcircuiting due to a sneak current to the transformerless power supply. 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 differ in phase, otherwise the terminals will be short-circuited to one another. Incorrect Contact or transistor for external input signal Input terminal Isolation transformer is required. Input device H3CR-A Short-circuit current Power supply Incorrect G, S, R 5, 6, 7 2 H3CR-A Input terminal 10 Input terminal Power supply 2 Correct Contact or transistor for external input signal Input device H3CR-A Input terminal Isolation transformer Power supply The H3CR-A's power supply terminal 2 is a common terminal for input signals to the Timer. Do not disconnect the wires on terminal 2, otherwise the internal circuitry of the Timer will be damaged. Input terminal 5, 6, 7 G, S, R AC or DC Power Supply Input terminal 10 H3CR-A 2 It is impossible to provide two independent power switches as shown below regardless of whether or not the Timers are different in phase. Contact or transistor for external input signal H3CR-A Input terminal Input terminal 23 Power supply H3CR-A Relationship between Input and Power Supply Circuits (H3CR-A@/-A@S) An appropriate input is applied to the input signal terminals of the H3CR-A@/-A@S when one of the input terminals is short-circuited with the common terminal (terminal 2) for the input signals. Never use terminal 10 as the common terminal for this purpose, otherwise the internal circuit of the Timer will be damaged. 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 (refer to the figures below). Incorrect Contact or transistor for external input signal 10 6 Correct H3CR-AP 7 10 5, 6, 7 G, S, R Input terminal AC or DC power supply Power supply 2 H3CR-A/-AS 10 6 2 H3CR-AP 7 Incorrect Short-circuit current 2 10 AC or DC power supply 5, 6, 7 G, S, R Correct Contact or transistor for external input signal H3CR-A/-AS 10 6 Input terminal 2 *1 7 Power supply H3CR-AP 2 *2 10 Ry AC or DC power supply 5, 6, 7 G, S, R H3CR-A/-AS Input terminal Input contact Short-circuit current 6 7 10 H3CR-AP 2 2 *1 Power terminal 2 is a common terminal that is also used for the input signal. Do not use terminal 10 as a common terminal as this will damage the internal circuitry. *2 If a relay or other load is connected here, high voltage will be applied to the input terminal and damage the internal circuitry. * The transistor output of the H3CR-A@S is isolated from the internal circuitry by a photocoupler, and can therefore be used either as an NPN output type or a PNP (equivalent) output type. Relationship between Input and Power Supply Circuits (H3CR-AP) When using the timer in an environment where considerable noise occurs, keep the input signal source device, timer unit, and wiring as far away as possible from the source of the noise. It is also recommended that shielded wire be used for the input signal wiring as a countermeasure for noise. Common to All H3CR-A Models With the H3CR-AP, input wires must be as short as possible. If the floating capacity of wires exceeds 1,200 pF (approx. 10 m for cables with 120 pF/m), the operation will be affected. Pay particular attention when using shielded cables. The H3CR-A@S transistor output is isolated from the internal circuitry by a photocoupler. Therefore, either NPN or PNP output is possible. H3CR-AP AC/DC power supply Input circuit Power supply circuit Since the input circuit and the power supply circuit are configured independently, the input circuit can be turned ON or OFF irrespective of the ON/OFF state of the power supply. It must be noted that a voltage equivalent to the power supply voltage is applied to the input circuit. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.

Power Supplies Wiring The H3CR-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. With the H3CR-H@RL, for the power supply of an input device, use an isolating transformer, of which the primary and secondary windings are mutually isolated and the secondary winding is not grounded. The H3CR-H has a high impedance circuit. Therefore, the H3CR-H may not be reset if the H3CR-H is influenced by inductive voltage. In order to eliminate any influence of inductive voltage, the wires connected to the H3CR-H must be as short as possible and should not be installed alongside power lines. If the H3CR-H 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 F and a resistance of approximately 120 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.

If the H3CR-H is turned on and off repeatedly with an interval of shorter than 3 s, abnormal heating or burning may occur in internal elements. 3 s min. Isolation transformer is required.

Do not attempt to connect any input terminal to any terminal other than the input terminal or to apply voltage across other than the specified input terminals or the internal circuits of the Timer may be damaged. The H3CR-H@RL uses transformerless power supply. When connecting a relay or transistor as an external signal input device, pay attention to the following points to prevent short-circuiting due to a sneak current to the transformerless power supply. If input is made simultaneously from one input contact or a transistor to the H3CR-H and a Timer whose common input terminals are used as power terminals, such as the H3CR-A, a short-circuit current will be generated. Either input through isolated contacts, or isolate the power supply for one of the Timers. H3CR-H@RL 10, 7* 1*, 5 2, 2* After the forced reset function of the H3CR-H is activated, an interval of 3 s minimum is required to activate the forced reset function again. If the forced reset function is activated repeatedly with an interval of shorter than 3 s, the internal parts of the H3CR-H may deteriorate and the H3CR-H may malfunction. Power Input/Output (H3CR-H@RL) 4*, 7 Power 3 s min. 3 s min. Reset input Output If it is required that the output be turned on repeatedly with an interval of shorter than 3 s, consider use of the H3CR-A in mode D (signal OFF-delay). On the H3CR-F@, do not set both the ON set dial and OFF set dial to the lowest settings. Doing so may damage the contacts. Others If the H3CR-H is dropped or experiences some other kind of shock, because a latching relay is used for output, contacts may be reversed or go into a neutral state. If the H3CR-H is dropped, reconfirm correct operation. Short-circuit current G. S. R. 5 6 7 10 H3CR-A 2 *: H3CR-H8RL ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.

Warning Indications CAUTION Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or in property damage. Precautions for Safe Use Supplementary comments on what to do or avoid doing, to use the product safely. Precautions for Correct Use Supplementary comments on what to do or avoid doing, to prevent failure to operate, malfunction or undesirable effect on product performance. In rare circumstances there is a risk of slight electrical shock, fire, or device damage. Do not disassemble, modify, repair, or otherwise touch the inside. In rare circumstances there is a risk of fire if the screws become loose. Tighten the terminal screws to the specified torque (1.08N*m). Meaning of Product Safety Symbols Used to warn of the risk of electric shock under specific conditions. Used for general prohibitions for which there is no specific symbol. Use to indicate prohibitions when there is a risk of minor injury from electrical shock or other source if the product is disassembled. Precautions for Safe Use Do not use the Timer in the following locations. * * * * * Locations with radical temperature changes. Locations with high humidity that may result in condensation. Locations with excessive vibration or shock. Locations with corrosive gas or dust. Locations where the Timer is exposed to sprayed water, oil, or chemicals. Pay the utmost attention not to make mistakes in polarity when wiring the Timer. Do not connect anything to terminals that are not used. Risk of internal element damage if a voltage that exceeds the rating is applied. Using a surge absorber is recommended if surge voltages occur. Used for general mandatory action precautions for which there is no specified symbol. CAUTION Risk of fire and explosion due to arcing and relay heat generation that accompanies switching. Do not use in an environment where flammable or explosive gas is present. The H3CR series uses a transformer-less power supply. Exercise full caution as there is a risk of electrical shock if input terminal is touched when power voltage is applied. The H3CR Series uses a transformerless power supply. Do not touch the input terminals while the supply voltage is applied, otherwise an electric shock may be received. Verify that the power and output LEDs (LCD) are operating normally. In some usage environments, the LEDs/LCD/ resin components may deteriorate faster than normal, resulting in display failure. Inspect and replace regularly. When disposing of this product, follow the procedures for disposal of industrial waste that apply in your region. Verify that the product is the desired product before use. Exercise caution as the outer casing of the timer may be immersed in organic solvents (thinner, benzene, etc.), strong alkali, or strong acids. Precautions for Correct Use The service life of the output relay varies widely depending on switching capacity and switching conditions. Use only within the rated load and electrical life count, based on actual conditions of use. Risk of contact sticking and burning if used past the service life. Always use a load current that does not exceed the rating, and if a heater is used, use a thermal switch in the load circuit. Do not remove the outer casing. Changing the Setting Do not change the time unit, time range, or operation mode while the Timer is in operation, otherwise the Timer may malfunction. The time unit and time range can be set with the respective selectors turned clockwise or counterclockwise. The selectors are of notched so that they will snap when they are properly set. Do not set the selectors midway between notches, otherwise the Timer may break or malfunction. Do not use H3CR-A models (except for H3CR-A@S) in flicker mode at the lowest selector setting, or H3CR-F models at the lowest selector setting. Doing so may result in damage to contacts. 58 H3CR Power Supplies Others A DC power supply can be connected if its ripple factor is 20% or less and the mean voltage is within the rated operating voltage range of the Timer. If the Timer is mounted to a control board, dismount the Timer from the control board or short-circuit the control board circuitry before carrying out a voltage withstand test between the electric circuitry and non-charged metal part of the Timer. This protects the internal circuitry of the Timer from damage. An AC power supply can be connected to the power input terminals without regard to polarity. A DC power supply must be connected to the power input terminals as designated according to the polarity of the terminals. Make sure that the voltage is applied within the specified range, otherwise the internal elements of the Timer may be damaged. Connect the power supply voltage through a relay or switch in such a way that the voltage reaches a fixed value at once, otherwise the Timer may not be reset or a timer error may result. Be aware that the operating voltage will rise by 5% if the rated voltage is applied to the Timer continuously while the ambient temperature is close to the maximum permissible ambient temperature. The power supply circuit of any H3CR-A model (except for H3CRA@S), H3CR-F 100-to-240-VAC model, and H3CR-G model is a switching circuit. If the power line connected to the power supply circuit has a transformer with high inductance, a counterelectromotive voltage will be induced by the inductance. To suppress the voltage, apply a CR filter to the power supply line. Apply the power voltage at once through the switch and relay contacts. If not applied at once, power reset may not take place or time-up may occur. When the power is turned on, a rush current (refer to your OMRON website) may flow briefly and the timer may not start if there is insufficient power capacity. Use a power supply with sufficient capacity. If the timer is left for an extended time at high temperature in the time-up state (internal relay ON), the internal components (electrolytic capacitors, etc.) may deteriorate faster than normal. For this reason, use in combination with a relay, and avoid leaving in the time-up state for an extended time (for example, one month or longer). (Excluding H3CR-H) Reference example Use as shown below. X2/b T T/a X1 X1/a X1/a X2 X : Auxiliary relay, MY relay, etc. Cleaning Do not use solvents such as thinner. Use commercially available alcohol. Mounting Direction There are no restrictions to the mounting direction.
