Warning Indications CAUTION Precautions for Safe Use 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. 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. Used for general mandatory action precautions for which there is no specified symbol. CAUTION Do not touch the terminals while power is being supplied. Doing so many occasionally result in minor injury due to electric shock. Do not use the product where subject to flammable or explosive gas. Otherwise, minor injury from explosion may occasionally occur. • Make sure the proper product is specified for the application. • For correct use, do not subject the timer to the following conditions. • Dramatic temperature fluctuations • High humidity or where condensation may occur • Severe vibration and shock • Where excessive dust, corrosive gas, or direct sunlight may be present • This product is not waterproof or oil resistance. Do not use the product in any of the places subject to splashing liquid or oil atmosphere. • Use and store the product within the rated ranges given for the product model you are using. If necessary, use forced cooling. If the product is stored below −10°C, allow it to warm up for three hours at room temperature before turning On the power supply. • 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 mm2). (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. • 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. • 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 apply the supply voltage directly from external to transistor output. Never disassemble, modify or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur. 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. Tighten the terminal screws to between 0.74 and 0.90 N·m. Loose screws may occasionally result in fire. 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. 12 13 External power supply 14 or or 8 or • A constant reading system is used in the present counter, so settings can be changed while power is being supplied, but the output will turn ON if the set value is set to the current measurement value. (If a setting switch is accidentally touched during operation, the set value will be changed and the new set value will be used for operation. Always leave the front panel cover closed unless you are changing a setting.) • When changing the set count while power is being supplied, an inadequate push of the thumb wheel switches will display two numbers in one display window, causing the operating count to drift widely. Therefore, press the thumb wheel switches surely. • Turn the power OFF first when removing the body from the case, never touch the terminals or electronic components with your hands or subject them to shock. When inserting the body, do not allow electronic components to come in contact with the case. • Static electricity may destroy internal components. When removing the body form the case, do not touch an electronic components other than the setting switches with your hands. 17 H7AN • 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. • Use tools when separating parts for disposal. • When disposing of the product, observer all local ordinances as they apply. 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.23 A for 264 VAC 12 to 24 VDC specifications Approx.15 A for 26.4 VDC • After turning ON the power supply, 50 ms is required for the internal circuits to reach the operating voltage. Operation for input signals may not be correctly during this time. • After turning OFF the power supply, 50 ms is required for voltage in the internal circuits to drop. Operation may be performed for input signals during this time. Power 50 ms Possible When an error has occurred, the bellow error codes are shown. 7 segment display Counting operation unstable • Models without power failure memory backup or models ending with "-M" (when memory backup is disabled) will operate as shown in the following figure if the power supply is momentarily interrupted. Power • 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 status before the power interruption will be held. 0.01 to 0.5 s Operation will be unstable, i.e., one of the above operations will be performed. Note: Use a Counter with power failure backup memory (models ending with -M) and enable memory backup if holding the status before the power failure is required when the power is interrupted. • The following timing chart shows how the H7AN indicates when there is an external or manual reset input. Reset ON OFF ON Reset indicator OFF Count display Display before reset Off Display after reset • To mount the casing on the digital counter, insert the digital counter body into the casing by hand as far as possible and then tighten the mounting screw. Press by the hand the front panel as indicated by the arrow so that the screw will tighten securely. 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, if the display remains the same even when turn power ON again, input reset. After that, if it still remains the same, the product must be repaired. ■ Changes in Specifications This product was upgraded in January 2006. The main changes are described below. 1. Maximum Counting Speeds A DIP switch on models with 4, 6, or 8 digits could be used to set the maximum counting speed to 3 kHz, 5 kHz, or 30 kHz. The upgraded models have been changed so the maximum counting speed can be set to 5 kHz or 30 kHz. 2. Addition of Setting to Enable/Disable Data Backup for Power Interruptions On models that back up data when power is turned OFF (models with model numbers ending in “-M”), a DIP switch setting has been provided to enable or disable backup. 3. Changes in Functions Allocated to Function Setting Switches Some of the functions allocated to the DIP switches have been changed to allow for the changes described in 1 and 2, above.
