- Terminals 1 and 2 are internally connected for Timers with DC power. 

- A diode is internally connected between terminals E and F for the H5CN-X @ NS to absorb counterelectromotive force that occurs when an inductive load is connected. 

## ■ **Power Connection** 

## **H5CN@@ N and H5CN-X-XX @ NS H5CN-X-XX @ NM (with Memory Backup)** 

## **(without Memory Backup)** 

- Do not allow the applied power supply to exceed the operating voltage range. 

- Make sure that the polarity of the DC power supply is correct. 

## ■ **Input Connection** 

## **Reset Input Connection** 

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 high-reliability goldplated 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 μ A max. 

VCE(sat) (residual voltage) = 2 V max.

**H5CN** 

## **Gate Input Connection** 

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.

## ■ **Protective Cover** 

The Protective Cover shields the front panel, particularly the count value setting section from dust, dirt and water, and prevent malfunctioning of the Timer due to static electricity. 

- **Note: 1.** The Hard Protective Cover prevents the set count value from being altered due to accidental contact with the pushtype thumbwheel switch. 

   **2.** The Soft Protective Cover allows the set value to be set by depressing the thumbwheel switches through it. It may be, however, difficult to make setting changes of the Timer with the Y92A-48B Protective Cover attached, which must be taken into consideration before using the Y92A48B Protective Cover.

**Used to warn of the risk of electric shock under specific conditions.** 

- Do not cover the vent holes on the products and the area around the product in order to ensure thermal dissipation. 

- **•** Wiring all terminals correctly. **•** Do not wire the terminals which are not used. **•** Use specified size crimped terminals (M3.5, thickness 7.2 mm max.) for wiring with a gage of AWG 24 to AWG 18 (equal to a cross section area of 0.205 to 0.823 mm[2] ). (The wiring stripping length is 5 to 6 mm.) Up to two wires of same size and type, or two crimped terminals can be inserted into a single terminal. 

**Used for general prohibitions for which there is no specific symbol.** 

**Used for general mandatory action precautions for which there is no specified symbol.** 

- Use this product within the rated power supply voltage and control output. 

- **•** Use a switch, relay, or other contact to turn the power supply ON instantaneously. If the voltage is applied gradually, the power may not be reset or output malfunctions may occur. 

## **CAUTION** 

Do not touch the terminals while power is being supplied. Doing so many occasionally result in minor injury due to electric shock. 

**==> picture [34 x 71] intentionally omitted <==**

- Do not apply the supply voltage directly from external to transistor output. 

- **•** Interlock the power to the product with a relay so that the product will not be left in an output on condition for long periods. Leaving the product in an output-on condition for a month or longer, especially in places with high temperatures, may result in deterioration to internal parts, such as an electrolytic capacitor. 

Do not use the product where subject to flammable or explosive gas. Otherwise, minor injury from explosion may occasionally occur. 

Never disassemble, modify or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur. 

|**•** Internal circuit voltage (5 V) is output to the no-<br>voltage input terminals, which may cause some<br>connected devices to malfunction or fail. Check the<br>specifications of the input device (e.g., rated output<br>voltage or whether a power supply circuit diode is<br>built in).<br>Sensor<br>Input<br>0V|||||

The life expectancy of output relays varies considerably with the output load and switching conditions. Always consider the application conditions and use the output relays within their rated load and electrical life expectancy. If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur. Also, never exceed the rated load current. When using a heater, surely use a thermo switch in the load circuit. 

**==> picture [32 x 32] intentionally omitted <==**

To prevent power supply devices from being subjected to charging accidents, connect a diode as in the figure when using a power supply voltage of 5 V or less to operate input devices that do not have a diode built into the power supply circuit. 

- Check that the LED 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. 

Tighten the terminal screws to between 0.74 and 0.90 N·m. Loose screws may occasionally result in fire. 

**==> picture [32 x 70] intentionally omitted <==**

- Use tools when separating parts for disposal. 

- When disposing of the product, observer all local ordinances as they apply. 

Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction. 

## **Precautions for Correct Use** 

- Inrush current will be carried when turning on the power. If the capacity of the power for the product is insufficient, the product cannot start. Use a power supply, breakers, contacts which sufficient capacity. 

- 100 to 240 VAC specifications Approx. 0.8 A for 264 VAC 12 to 48 VDC specifications Approx. 0.4 A for 52.8 VDC 

- Since 50 ms after the power is turned ON is required as the raise time of the internal circuit voltage, note that the product may not operate in response to any input signal during this period. 

**12** 

**H5CN** 

- Since100 ms after the power is turned OFF (or momentary power failures) is required as the fall time of the internal circuit voltage, note that the product may respond to input signals during this period.

- Models without power failure memory backup will operate as shown in the following figure if the power supply is momentarily interrupted. 

|ON<br>OFF<br>Power|ON<br>OFF<br>Power||||||
|---|---|---|---|---|---|---|
||||||||
|||Momentary po<br>interruption|||||
||||||||

|0.5 s min.|||Displays and outputs will be reset.||||
|0.01 s max.|||The status before the power interruption will be<br>held.||||
|0.01 to 0.5 s|||Operation will be unstable, i.e., one of the above<br>operations will be performed.||||



- **Note:** Use a Timer with power failure backup memory (models ending with -M) if holding the status before the power failure is required when the power is interrupted. 

- All number display digits on the Timer will be OFF when the reset signal is input. When the reset signal is completed, the numeric display will show the reset value. 

- Model H5CN 12-48 VDC specification use transformer-less power supply which the power terminals and input terminals are not insulated. When use this specification, the internal parts of the product may be occasionally burnt (damaged) if the wiring is not correct. Pay attention to check the wiring before use. 

- 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 causing the timer to operate with a different set time. To prevent this possibility, use the optional Y92A-48B Protective Cover. 

- 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. 

- 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 count 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. 

## **Undesirable changes in the settings**

## **Operation Examples** 

- 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: 

Old set value New set value 200 s **->** 100 s Present value Present set value (before changing setting) (after changing setting) 160 s **->** 60 s 

## **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). 

## **Power Failure Backup Memory** 

- The product memorizes the status just before occurring the electric failure memory with non-volatile memory. The rewriting lifespan of the non-volatile memory is 1,000,000 or more. The non-volatile memory rewrites the setting condition into the initial setting one when the power OFF. (-M type only) 

## ■ **Self-diagnostic Function** 

When an error has occurred, the bellow error codes are shown. 

|**7 segment**<br>**display**|**Time UP**<br>**display**|**Description**|**Output**|
|---|---|---|---|
|e1|OFF|CPU error|OFF|
|e2|OFF|Memoryerror (RAM)|OFF|
|e3|OFF|Memory error<br>(non-volatile memory)*|OFF|



- Including the case when the rewriting lifespan of the nonvolatile memory is reached. 

## Recovery method 

As an action, turn the power OFF then back ON again. If the display restored to normal, then a probable cause can be external noise affecting the system. Check for external noise. In the case of e3 , input gate (“0000” will be displayed) and turn power ON again. After that, if it still remains the same, the product must be repaired. 

## ■ **Changes in Specifications** 

**The Timer manufactured in April 2014 or after will be upgraded. The major changes are described below.** 

   - **Backup Battery Connection to Timers with Memory Backup Previously, an external backup battery was required for Timers with memory backup, but the Timer has been upgraded so that the external battery is no longer necessary.** 

- 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.)
