Battery Connection (H5CN-X@NM Only) Connecting of Load Circuit Load 1 connected in series with NO contact (between terminals F and H) is normally open, and the load circuit voltage will be applied after the lapse of the set time. The load circuit voltage is normally applied to load 2 connected in series with NC contact (between terminals E and H), which will be open after the lapse of the set time. Load 2 Model with Backup Power for Memory Protection External battery 3 V Connect the Y92S-20 Backup Battery between terminals A and D, making sure the polarities are correct. Load 1 Load circuit voltage (250 VAC, 30 VDC max.) Note: The maximum load current is 3 A (resistive load). 2. Power Supply Connection Solid-state Output Type Model without Backup Power for Memory Protection Internal Circuit of Control Output Terminals F and H are an open collector output. A diode is internally connected between terminals E and F to absorb counterelectromotive force that occurs when an inductive load is connected. Connect the timer so that the required supply voltage can be applied across terminals B and G. (Make sure that the polarity of the DC power supply is correct.) AC Power Supply DC Power Supply Connection of Load Circuit Voltage is applied to the load after the set time has lapsed. 12 to 48 VDC 100 to 240 VAC Model with Backup Power for Memory Protection (H5CN-X@NM) Load Load voltage (30 VDC max.)

Load 2 Load 1 External battery Load circuit voltage (250 VAC, 30 VDC max.) Note: The maximum load current is 3 A (resistive load). 4. Connection of Reset Input Connection of the reset input contact or an open collector transistor between terminals A and C (between terminals C and G for models with backup power for memory protection) permits the timer to reset when contact is made or the transistor turns ON. Use of a highreliability gold-plated contact is recommended for the reset input. For the reset input transistor, select the one satisfying the following electrical ratings: VCEO = 20 V min. IC = 50 mA min. ICEO (leakage current) = 0.5 m A max. VCE(sat) (residual voltage) = 2 V max. Model without Backup Power for Memory Protection Reset input contact (Timer resets when contact is made.) 5. Connection of Gate Input Connection of the gate input contact or an open collector transistor between terminals A and D (between terminals C and E for models with backup power for memory protection) permits the timer to stop operation while contact is made or the transistor turns ON. Use of a high-reliability gold-plated contact is recommended for the gate input. For the gate input transistor, select the one satisfying the following electrical ratings: VCEO = 20 V min. IC = 50 mA min. ICEO (leakage current) = 0.1 mA max. VCE(sat) (residual voltage) = 2 V max. Use a gate input contact with a short bounce time because the contact bounce time causes an error in the operate time of the timer for a period equalling the bounce time.

Battery Connections when Using Backup Power for Memory Protection Always connect a battery when using models with backup power for memory protection (H5CN-X@NM). Any 3-V battery can be used, but the backup time will depend on the capacity of the battery. When using the Unit for the first time after purchase, apply power and reset the Unit once before using it. When power is turned ON for the first time, outputs may be produced at the same time, so do not connect the output terminals. When connecting the battery using a Socket (P2CF-11 or P3GA-11), check the terminal numbers on the Socket and connect the positive side of the battery to terminal D and the negative side to terminal A. Operation ■ Timing Chart Digital Display UP Display DOWN Display Time up Power ON Gate input Setting value Setting value Digital display No digital display Reset input Gate input Digital display 0 0 Power supply Power supply Control output Control output Time up indication Time up indication Time up No digital display Power ON Reset input Digital Timer H5CN 9 Dimensions Note: All units are in millimeters unless otherwise indicated. ■ Dimensions without Flush Mounting Adapter H5CN-X@N/-Y@N/-X@NS (Flush Mounting/Surface Mounting Models) 44.8 × 44.8 ▲ 8 pins H5CN-X@NM (Flush Mounting/Surface Mounting Models) 44.8 × 44.8 ▲ 11 pins ■ Dimensions with Flush Mounting Adapter H5CN-X@N/-Y@N/-X@NS (Adapter Ordered Separately) Panel Y92F-30 (order separately) Flush Mounting Adapter P3G-08 (order separately) Back Connecting Socket Panel Cutout The standard panel cutout is as below.

Do not short-circuit the positive and negative sides of the battery, recharge or disassemble the battery, deform the battery under pressure, or dispose of the battery in fire. Doing so may occasionally cause the battery to burst, ignite, or leak. Use only the specified battery. Otherwise, the battery may leak or burst, occasionally causing damage to the equipment or minor injury. ■ Precautions for Correct Use Battery Connections when Using Backup Power for Memory Protection Always connect a battery when using models with backup power for memory protection. Any 3-V battery can be used, but the backup time will depend on the capacity of the battery. When using the Unit for the first time after purchase, apply power and reset the Unit once before using it. When power is turned ON for the first time, outputs may be produced at the same time, so do not connect the output terminals. If a power interruption continues for 10 minutes or more when a battery is not connected, the count value and displays may be meaningless, and outputs may be produced unpredictably even if the power supply recovers. If this happens, apply power to the reset input once before using the Unit further. (The Unit can be used after turning ON the reset input, regardless of whether a battery is connected or not.) Regular battery replacement (every 4 to 5 years) is recommended. The life of the battery depends on the frequency of power failures. Time Setting Range Setting range Models 0.001 to 9.999 s H5CN-@Z@ 0.01 to 99.99 s H5CN-@A@ 0.1 to 999.9 s H5CN-@B@ 1 s to 99 min 59 s H5CN-@C@ 1 min to 99 h 59 min H5CN-@D@ 1. The H5CN Timer is capable of reading the input data at any time during normal operation. This means that the set time can be changed during power application. This feature sets back the output from the timer by temporarily setting the longer time or quickens the output by setting the shorter time. During normal operation, the set time may be accidentally changed by touching a thumbwheel switch. To prevent this possibility, use the optional Y92A-48@ Protective Cover. 2. When the set time is all zeroes (e.g., 000.0 s or 00 h 00 min), there will be a momentary control output upon power application, which can be used to check normal output. When changing the set time during normal operation, pay special attention not to alter the set value to this all zeroes. 3. When changing the set time while power is being supplied, an inadequate push of the thumbwheel switches will display two numbers in one digital display window, causing the operating time to drift widely. Therefore, press the thumb-wheel switches surely. Take particular care when the other three digits are all zeroes, because the improper setting of the fourth switch to create four zeroes will cause an instantaneous output.

Take particular care with the H5CN-@Z@, which is capable of setting in 1/1000th of a second because there is an error of between 0.03 to 0.05 ms. (Repeat accuracy is 1 to 2 ms.) Operation Examples Y92S-20 To terminal No. 1 To terminal No. 4 5 min 30 s • During Incremental Operation If the set value is changed to a value higher than the currently displayed present value, the timer will time out for the new set value. • During Decremental Operation When the set value changes, the difference between the new set value and old set value will be added or subtracted from the present value. Example: P3GA-11 Old set value 200 s New set value -> Present value (before changing setting) 160 s 100 s Present set value (after changing setting) -> 60 s Digital Timer H5CN 13 Power Supply Leave the power supply OFF for at least 0.5 s before turning it back ON (power supply reset). Inputs and Outputs • Do not apply voltage externally to input terminals A, C, and D. • When using contacts for the reset input and gate input, use goldplated contacts with good contact reliability. Use gate input contacts with short contact bounce (chattering). Operation during Power Failures • When Units without backup power for memory protection are used, the timer status during momentary power failures is as shown in the following diagrams. A. Power Failure of 0.01 s Max. m−2 m−1 m m+1 m+2 Power failure *Restarts from status before power failure. B. Power Failure of 0.5 s Min. m−2 m−1 m 1 2 3 Power failure *Restarts from initial status after power reset. C. Power Failure of 0.01 to 0.5 s Max. m−2 m−1 m 1 m m+1 m+2 2 3 Power failure *Either A or B are undefined. • Units with backup power for memory protection will restart from the status before the power failure as shown in example A, regardless of the length of time of the power failure. 14 Digital Timer H5CN Warranty and Application Considerations Warranty and Limitations of Liability WARRANTY OMRON's exclusive warranty is that the products are free from defects in materials and workmanship for a period of one year (or other period if specified) from date of sale by OMRON.
