SAFETY PRECAUTIONS

Keys to Warning Symbols

CAUTION: Indicates a potentially hazardous situation which, if not avoided, is likely to result in minor or moderate injury or property damage.

Precautions for Safe Use

• Minor electric shock, fire, or malfunction may occasionally occur. Do not disassemble, modify, or repair the Counter or touch internal components.
• The life expectancy of the output relay varies considerably according to its usage. Use the output relay within its rated load and electrical life expectancy. If the output relay is used beyond its life expectancy, its contacts may become fused or there may be a risk of fire. Also, be sure that the load current does not exceed the rated load current and when using a heater, be sure to use a thermal switch in the load circuit.
• Minor injury due to electric shock may occasionally occur. Do not touch any of the terminals while power is being supplied. Be sure to mount the terminal cover after wiring.
• Fire may occasionally occur. Tighten the terminal screws to the rated torque. (H7CC terminals and P3GA-11/P3G-08 Socket terminals: 6.55 to 7.97 lb-in (0.74 to 0.90 N·m); P2CF Socket terminals: 4.4 lb-in (0.5 N·m))
• Minor injury due to explosion may occasionally occur. Do not use the Counter where subject to flammable or explosive gas.
• Do not allow pieces of metal, wire clippings, or fine metallic shavings or fillings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction.

Precautions for Correct Use

• Read this manual carefully before using the product.
• An inrush current of approx. 10 A will flow for a short time when the power supply is turned ON. If the capacity of the power supply is not sufficient, the Counter may not start. Be sure to use a power supply with sufficient capacity.
• Make sure the power supply voltage and loads are within the specifications and ratings for the product.
• To allow for the startup time of peripheral devices (e.g., sensors), start Counter timing operation 200 ms to 290 ms after turning ON the power. The input signal will not be accepted before 200 to 290 ms has elapsed.
• The input signal will not be accepted after 5 to 1005 ms has elapsed from when the power supply is turned OFF.
• Inrush current generated by turning ON or OFF the power supply may deteriorate contacts on the power supply circuit. Turn ON or OFF to a device with the rated current of more than 10 A.
• The capacity of the external power supply is 100 mA at 12 V. When using a 24 VAC/12 to 48 VDC power supply, reduce the load with the power supply voltage, as shown in the diagram (DC power supplies only) on the right.
• If the prescale value setting is incorrect, a counting error will occur. Check that the settings are correct before using this function.
• Make sure that all settings are appropriate for the application. Unexpected operation resulting in property damage or accidents may occur if the settings are not appropriate.
• Do not leave the Counter for long periods at a high temperature with output current in the ON state. Doing so may result in the premature deterioration of internal components (e.g., electrolytic capacitors). Do not install the product close contact with the heating element.
• Non-volatile memory is used as backup memory when the power is interrupted. The write life of the non-volatile memory is 100,000 writes. The non-volatile memory is written when the power is turned OFF or when switching from function setting mode or configuration selection mode to run mode.
• Dispose of the product according to local ordinances as they apply.
• Attach the front panel when using the Counter. The latches in the middle of each of four sides secure the front panel to the main body. To remove the panel, widen the four latches and pull the panel toward you. To mount the panel, fit all four latches correctly into the slots on the main body.
• Do not use because it may be damaged inside the product when the product falls by mistake.
• Confirm the wiring of the input and output terminals correctly before power is supplied.
• Do not use the product near radio wave receivers. Doing so may cause incoming radio wave interference.
• Do not use in a circuit with a distorted waveform. The error will increase due to the influence of the distorted waveform.
• Install product so that the load doesn't span the product body.
• When mounting the Counter to a panel, tighten the two mounting screws alternately, a little at a time, so as to keep them at an equal tightness. If the panel screws are tightened unequally, water may enter the panel.
• Store the Counter at the specified temperature. If the Counter has been stored at a temperature of less than -10°C, allow the Counter to stand at room temperature for at least 3 hours before use.
• Mounting the Counter side-by-side may reduce the life expectancies of internal components.
• Use the Counter within the specified ranges for the ambient operating temperature and humidity.
• Do not use or store the product in the following locations: Locations subject to sudden or extreme changes in temperature; where high humidity may result in condensation; with excessive vibration or shock; subject to water; subject to oil; prone to icing; subject to exposure to chemicals; subject to bugs and small animals.
• Do not use this Counter in dusty environments, in locations where corrosive gasses are present, or in locations subject to direct sunlight.
• Install the Counter well away from any sources of static electricity, such as pipes transporting molding materials, powders, or liquids.
• Internal elements may be destroyed if a voltage outside the rated voltage range is applied.
• Be sure that polarity is correct when wiring the terminals.
• Separate the Counter from sources of noise, such as devices with input signals from power lines carrying noise, and wiring for I/O signals.
• Do not connect more than two crimp terminals to the same terminal.
• Up to two wires of the same size and type can be inserted into a single terminal.
• Use the specified wires for wiring. Applicable Wires: AWG 18 to AWG 22, solid or twisted, copper.
• Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to clearly indicate its function.
• When the Counter is operated with no-voltage input (NPN input), approximately 14 V is output from the input terminals. Use a sensor that contains a diode.
• Use a switch, relay, or other contact so that the rated power supply voltage will be reached within 0.1 second. If the power supply voltage is not reached quickly enough, the Counter may malfunction or outputs may be unstable.
• Use a switch, relay, or other contact to turn the power supply OFF instantaneously. Outputs may malfunction and memory errors may occur if the power supply voltage is decreased gradually.
• When changing the set value during operation, because the H7CC uses a constant read-in system, output will turn ON if the set value is equal to the present value.
• If the set value and present value are both 0, the output will turn ON for the default setting. The output will turn OFF during a reset operation.
• Do not use organic solvents (such as paint thinners or benzine), strong alkali, or strong acids. They will damage the external finish.
• Confirm that indications are working normally, including the backlight LEDs, and LCD. The indicator LEDs, LCD, and resin parts may deteriorate more quickly depending on the application environment, preventing normal indications. Periodic inspection and replacement are required.
• The waterproof packing may deteriorate, shrink, or harden depending on the application environment. Periodic inspection and replacement are required.

Ratings (Specifications)

These show connections for power supply, sensor, reset inputs (CP1, CP2, Total reset, Reset 1, Reset 2), and outputs (OUT1, OUT2).

Input Connections:

• No-voltage Inputs (NPN Inputs): Diagram shows connection of PLC, Sensor to input terminals with 0V, Reset, CP. Note: Operate with transistor ON.
• Voltage Inputs (PNP Inputs): Diagram shows connection of Sensor to input terminals with 0V, Reset, CP. Note: Operate with transistor ON.
• Open Collector: Diagram shows connection of Sensor to input terminals with 0V, Reset, CP. Note: Operate with transistor OFF.
• No-contact Input (NPN Transistor): Diagram shows connection of Sensor to input terminals with 0V, Reset, CP. Note: Operate with transistor ON.
• No-contact Input (PNP Transistor): Diagram shows connection of Sensor to input terminals with 0V, Reset, CP. Note: Operate with relay ON.
• Contact Input: Diagram shows connection of Sensor to input terminals with 0V, Reset, CP. Note: Operate with relay ON.

Load Connection: Diagram shows Load connected to Power for load and Counter, with an inductive load noted.

* When an inductive load is connected to the H7CC. The diode connected to the collector of the output transistor is used to absorb inverted voltage that is generated when an inductive load is connected to the H7CC.

Key-protect Switch Settings

When the key-protect switch is ON, individual key operations can be disabled to prevent setting errors according to the key protect levels (KP-1 to KP-7).

Note: Key protect levels are set in function setting mode.

* Changing mode to configuration selection mode or function setting mode.

Self-diagnostic Functions

The following displays will appear if an error occurs:

*1. This includes times when the life of the non-volatile memory has expired.

*2. This occurs if the present value or total count value falls below –99999.

*3. This occurs in the following conditions if the present value (i.e., measurement value) exceeds 999999: For Output Modes K-2, D, L, or H; Dual counter or tachometer operation is used.

*4. Display flashes (1-second cycles).

*5. This does not apply when tachometer operation is used.

*6. This is displayed if the alarm set value for either of the two outputs is exceeded if a model with two outputs is used. The total ON count will not be cleared by using Reset operation.

*7. The normal display and Rplc will appear alternately. When Reset operation is performed, Rplc will no longer be displayed even if the alarm set value is exceeded. (Monitoring is possible, however, because the Counter will continue without clearing the total run time and the output ON count.) If the power supply is turned OFF/ON after the Rplc display is turned OFF by Reset operation, Rplc will be displayed again. In order to prevent the display even after the power supply is turned OFF/ON, change the alarm set value to equal to or greater than the count value, or change the alarm set value to 0 to be invalid.
