If the power supply capacity is too small, there may be delays in turning ON the output. 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 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. 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. Correct H3CR-H@RL 4*, 7 Input terminal 10, 7* 1*, 5 2, 2* Power supply * :H3CR-H8RL ■ Operation An interval of 3 s minimum is required to turn on the H3CR-H after the H3CR-H is turned off. 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. Input device Power Incorrect H3CR-H@RL 1*, 5 Output state 1 10, 7* 4*, 7 Input terminal Power supply 2, 2* * :H3CR-H8RL Input device Isolation transformer An appropriate input is applied to the input signal terminal of the Timer when the input terminal for the input signal is short-circuited. 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 Output state 2 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). ■ 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.

Timers with Built-in Batteries: H5L The Timer contains a lithium battery, which may occasionally ignite or rupture. Do not disassemble, deform under pressure, heat to 100°C or higher, or incinerate the Timer. 2. Timers with Replaceable Batteries: Y92S-20 (for H5CN-M) The battery may occasionally rupture, ignite, or leak fluid. Do not short the positive and negative terminals. Do not charge, disassemble, deform under pressure, or throw the battery into a fire. If a non-specified battery is used, the battery may leak fluid or rupture, occasionally resulting in equipment failure or minor injury. Use only the specified battery. • Normal operation may not be possible in locations subject to sulfidizing gas, such as in sewer systems or waste incinerators. OMRON does not market any Timers or other control devices for operation in atmospheres containing sulfidizing gas. Seal the Timer so that sulfidizing gas will not enter it. If sealing is not possible, OMRON does provide special Timers with improved resistance to sulfidizing gas. Ask your OMRON representative for details. Power Supply • Be sure that the voltage applied is within the specified range, otherwise the internal elements of the Timer may be damaged. • Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to clearly indicate its function. • Maintain voltage fluctuations in the power supply within Allowable Voltage Range the specified range. !CAUTION The following Timers contain lithium batteries that are explosion proof. Timers with Built-in Batteries: H5BR, H5AN-4DM, H5S, H5F, and H4KV The Timer contains a lithium battery, which may occasionally ignite or rupture. Do not disassemble, deform under pressure, heat to 100°C or higher, or incinerate the Timer. ■ Precautions for Safe Use Operating Environment • Use the Timer within the ratings specified for ambient operating temperature and ambient operating humidity for each model. • Store the Timer with the specified temperature range for each model. If the Timer has been stored at a temperature of less than −10°C, allow the Timer to stand at room temperature for at least 3 hours before using it. • Use the Timer within the performance specified for water and oil exposure for each model. • Do not use the Timer in locations subject to shock and vibration. Long-term usage in such locations may damage the Timer due to stress. Magnetic contactors generate a shock of 1,000 to 2,000 m/s2 when switching a load. When mounting to DIN Track, separate magnetic contactors from the Timer so that the Timer is not subjected to vibration and shock. Use anti-vibration rubber. • Do not use the Timer in locations subject to excessive dust, corrosive gases, or direct sunlight. • Do not use organic solvents (such as paint thinner or benzine), strong alkalis, or strong acids because they will damage the external finish of the Timer. • Separate the input devices, input wiring, and Timer as far as possible from sources of noise and power lines carrying noise. • When using the Timer in environments subject to large amounts of static electricity (e.g., pipes carrying molding materials, powders, or fluid materials), separate the Timer as far as possible from the sources of static electricity. • Do not remove the external case from the Timer. • Do not use the Timer in locations where condensation may occur due to high humidity or sudden temperature changes. Condensation inside the Timer may result in malfunction or damage to Timer elements. • The life of internal parts may be reduced if Timers are mounted in close proximity to each other. • Resin and rubber parts (e.g., rubber packing) may deteriorate, shrink, or harden depending on the operating environment (e.g., subjected to corrosive gases, ultraviolet light, or high temperatures). We recommend periodic inspection and replacement. http://www.ia.omron.com/ • Use a commercial power supply for the power supply voltage input to models with AC inputs. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal temperature of the Timer may result in ignition or burning. Do not use an inverter output for the power supply of the Timer. • The Timers listed below cannot be directly turned ON and OFF by using an AC 2-wire proximity sensor to turn the Timer's power supply ON and OFF. Use the following countermeasure when using an AC 2-wire proximity sensor with the Timer. (The power supply circuit in the Timer uses half-wave rectification. Only a half AC wave is supplied to the proximity sensor, which may cause operation to be unstable.) Applicable Models H3Y, H3YN, H3RN, H3CA-8, RD2P, and H3CR(-A, -A8, -AP, -F, and -G) Countermeasure Wire through a relay and use the relay contacts to turn the power supply ON and OFF. Confirm the stability of operation after making the connections. • Install protective measures (such as earth leakage breakers, wiring breakers, or fuses) on the power supply side according to any applicable laws or regulations. (c)Copyright OMRON Corporation 2007 All Rights Reserved. C-1 Correctly Handling Input Signals Other Precautions Malfunction due to noise may occur if input wiring is placed in the same duct or conduit as power lines or high-voltage lines. Separate input wiring from power lines and wire them in a separate system. Also, use shielded cables, use metal conduits, and keep wiring distances as short as possible. • Confirm that you have the correct model before using it. • Be sure that all terminals are wired correctly. • Always test the output status with a tester before using a Timer with a built-in keep relay (e.g., the H3CR-H and H3DE-H). Shock resulting from dropping the Timer during transport or handling may cause the output contacts to reverse or to be in a neutral status. • Leaving the Timer with outputs ON at a high temperature for a long time may hasten the degradation of internal parts (such as electrolytic capacitors). Use the Timer in combination with relays and avoid leaving the Timer with the output turned ON for an extended period of time (e.g., for more than a month). Reference Example (Use the Timer as shown below.) Timers with Relays • Do not connect a load that exceeds contact ratings, such as the switching capacity (contact voltage or contact current). Insulation faults, contact welding, contact faults, and other failures to achieve specified performance may occur and the relay may be damaged or may burn. • Continued use with deteriorated performance may ultimately result in insulation breakdown between circuits or relay burning. The life of the built-in relay is greatly affected by switching conditions. Before using the Timer, test operation under actual application conditions and confirm that the switching frequency presents no problems in performance. • Electrical life depends on the type of load, switching frequency, and ambient environment. Observe the following precautions when using the Timer. When switching a DC load, contact transfer may cause the contacts to stick or may cause contact failure. Confirm applicability and consider using a surge absorbing element. When switching at high frequencies, heat generated by arcing may cause contacts to melt or may cause metal corrosion. Consider connecting an arc absorbing element, reducing the switching frequency, or lowering the humidity. • The surge current depends on the type of load, which also affects contact switching frequency and the number of operations. Check the rated current and the surge current, and design the circuits with sufficient margin. Resistive load Solenoid load Rated current Sodium light loads 10 to 20 times the rated current Capacitor loads 1 to 3 times the 20 to 40 times rated load the rated load Motor load 5 to 10 times the rated current Transformer loads 5 to 15 times the rated load X2/b T T/a X1 X1/a X1/a X2 X Auxiliary relay (e.g., MY Relays) • Be sure that only a qualified worker (e.g., an electrical engineer) performs electrical work for the Timer. Incandescent lamp load 10 to 20 times the rated current Mercury light loads 1 to 3 times the rated load • Arcing when switching and relay heating may result in ignition or explosion. Do not use the Timer in atmospheres subject to inflammable or explosive gases. • Contact faults may occur. Do not use the Timer in atmospheres subject to sulfidizing gas, chloride gas, or silicon gas. • The switching capacity for DC voltage loads is lower than that for AC voltage loads. Timers with Non-contact Outputs • Short faults or open faults may occur due to destruction of the output element. Do not use the Timer for a load that exceeds the rated output current. • Short faults or open faults may occur due to destruction of the output element from reverse electromotive force. When using the Timer for a DC inductive load, always connect a diode as a countermeasure against reverse electromotive force. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
