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 Counter with the Y92A-48B Protective Cover attached, which must be taken into consideration before using the Y92A-48B 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 Counter due to static electricity.

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. 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 may 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. 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 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 from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction. Precautions for Safe Use • Make sure the proper product is specified for the application. • For correct use, do not subject the product 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 7.2mm max.) for wiring with a gage of AWG 24 to AWG 18 (equal to a cross section area of 0.205 to 0.823mm2). (The wiring stripping length is 5 to 6mm.) 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. • 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. • 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. • 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. • Internal circuit voltage (5 V) is output to the novoltage input terminals, which may cause some Sensor connected devices to malfunction or fail. Check the specifications of the input device (e.g., rated output voltage or whether a power supply circuit diode is 0V Input built in). To prevent power supply devices from being subjected to charging accidents, connect a diode as in the diagram 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. • Use tools when separating parts for disposal. • When disposing of the product, observer all local ordinances as they apply. 8 H7CN ■ Self-diagnostic Function 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. • Since 50 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. ON Power supply OFF 50 ms Input reception 50 ms Input can be received Counting operation unstable • Models without power failure memory backup will operate as shown in the following figure if the power supply is momentarily interrupted. ON Power supply OFF Momentary power interruption Operation after power interruption 0.5 s min. Displays and outputs will be reset. 0.01 s max. 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. When an error has occurred, the bellow error codes are shown. 7 segment display Count UP display Description Output e1 OFF CPU error OFF e2 OFF Memory error (RAM) OFF e3 OFF Memory error (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, 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 The Counter was upgraded in November 2005. The major changes are described below. • Backup Battery Connection to Counters with Memory Backup Previously, an external backup battery was required for Counters with memory backup, but the Counter has been upgraded so that the external battery is no longer necessary. Note: Use a Counter 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 Counter will be OFF when the signal is input for a external or manual reset. When the reset signal is completed, the numeric display will show the reset value. • Model H7CN 12-48 VDC specification use transformerless 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. 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 and reset input.
