Ultra-compact Counter Provides More Complete Functionality.

Basic Features

• Short body with depth of only 59 mm (for 12 to 24-VDC Models with Screw Terminals).

• Better readability with character height of 12 mm on 4-digit models and 10 mm on 6-digit models.

• The present value display characters can be switched between red, green, and orange.

Safety and Reliability

• New set value limit and counter functions have been added.

Other Features

• Front Panel can be changed to white or light gray.

• Models with two independent tachometer inputs have been added to the series.

*1.For 100 to 240-VAC Models with Screw Terminals: 78 mm, Models with Sockets: 63.7 mm (case dimension). *2.The H7CX-A11 and H7CX-R11 have only red characters. *3.The Front Panel can be replaced with an optional Front Panel (except for Tachometer-only Models).

Features

Basic Features

Ultra Short Body

The body depth has been greatly reduced. Helps in making thinner control panels.

12 to 24-VDC Models with Screw Terminals: 59 mm 100 to 240-VAC Models with Screw Terminals: 78 mm* Models with Sockets: 63.7 mm (case dimension)

* Power supply circuit and input circuits are isolated for safety and reliability.

New models

Easier to Read

For better readability, the character height for the present value display is 12 mm on models with 4 digits, the largest class in the industry. The wide viewing angle and brightness provide excellent visibility. The number of display segments has also been increased to make settings easier to understand, and the present value display can be switched between red, green, and orange so that output status can be seen from a distance.

Safety and Reliability

Isolated Power Supply and Input Circuits

Power supply circuit and input circuits are isolated inside the Counter/ Tachometer. Previous non-isolated counters had wiring restrictions and could be damaged if wired incorrectly. The H7CX removes these worries.

Note: Except 12 to 24-VDC models.

Set Value Limit

You can set an upper limit for the set value to prevent unexpected operation of output devices caused by setting mistakes.

Setting the upper limit of the set value enables worry-free operation.

For 1,000 pieces

Output Counter

The output counter counts the number of times the output turns ON (alarms can be displayed and the count can be monitored in increments of 1,000 operations). This counter is useful in managing the service life of the Counter/Tachometer or the load.

No overflow

The Easiest Operation

Operation is simplified by the Up/Down Key for each digit on 4-digit models and Up Key for each digit on 6-digit models.

Protecting the Counter/Tachometer in Environments Subject to Oil

The H7CX's panel surface is water-resistive (conforming to IP@6, UL Type 4X) and so even if drops of water penetrate the gaps between the keys, there will be no adverse effect on internal circuits. If, however, there is a possibility of oil being present on the operator's hands, use the Soft Cover. The Soft Cover ensures protection equivalent to IP54F against oil. Do not, however, use the H7CX in locations where it would come in direct contact with oil.

Flush Mounting Adapter

Y92F-30

Order the Flush Mounting Adapter with the following model number separately if it is lost or damaged.

Note: The

Waterproof Packing is included with models with screw terminals.

Y92F-45

Use this Adapter to install the Counter/ Tachometer in a cutout previously made for a DIN 72 × 72 mm device (panel cutout: 68 × 68 mm).

Waterproof Packing

Y92S-29

Note: The

Waterproof Packing is included with models with screw terminals.

The Waterproof Packing will deteriorate, harden, and shrink depending on the application environment. To ensure maintaining the IP@6, UL Type 4X waterproof level, periodically replace the Waterproof Packing. The periodic replacement period will depend on the application environment. You must confirm the proper replacement period. Use 1 year or less as a guideline. If the Waterproof Packing is not replaced periodically, the waterproof level will not be maintained. It is not necessary to mount the Waterproof Packing if waterproof construction is not required.

Order the Waterproof Packing separately if it is lost or damaged. The Waterproof Packing can be used to achieve IP66 protection.

Explanation of Functions

Items marked with stars ★ can be set using the DIP switch.

Input Mode (cntm)★

Set increment mode (UP), decrement mode (DOWN), or one of the increment/decrement modes (UP/DOWN A, UP/DOWN B, or UP/ DOWN C) as the input mode. Input modes other than UP or DOWN modes cannot be set using the DIP switch and so use the operation keys if other modes are required. (For details on the operation of the input modes, refer to Input Modes and Present Value on page page 21.)

Dual Count Calculating Mode ( calm)

When using as a dual counter, select either ADD (addition) or SUB (subtraction) as the calculation method for the dual count value. ADD: Dual count value = CP1 PV + CP2 PV SUB: Dual count value = CP1 PV − CP2 PV

Output Mode (outm)★

Set the way that control output for the present value is output. The possible settings are N, F, C, R, K-1, P, Q, A, K-2, D, L, and H. Output modes other than N, F, C, or K-1 cannot be set using the DIP switch and so use the operation keys if other modes are required. The output modes that can be set vary with the model. (For details on the operation of the output modes, refer to Input/ Output Mode Settings on page page 22.)

One-shot Output Time (otim)★

Set the one-shot output time (0.01 to 99.99 s) for control output. One-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is selected as the output mode. Output times other than 0.5 s or 0.05 s cannot be set with the DIP switch and so use the operation keys if other settings are required.

One-shot Output 2 Time (otm2)★

Set the one-shot output time (0.01 to 99.99 s) for control output (OUT2). One-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is selected as the output mode. Output times other than 0.5 s or 0.05 s cannot be set with the DIP switch and so use the operation keys if other settings are required.

One-shot Output 1 Time (otm1)

Set the one-shot output time (0.01 to 99.99 s) for control output (OUT1). One-shot output can be used only when D, L, or H is selected as the output mode. If the output time is set to 0.00, hold is displayed, and outputs are held.

Counting Speed (cnts)★

Set the maximum counting speed (30 Hz/5 kHz) for CP1 and CP2 inputs together. If contacts are used for input signals, set the counting speed to 30 Hz. Processing to eliminate chattering is performed for this setting.

Reset Input Signal Width (iflt)★

Set the reset input signal width (20 ms/1 ms) for reset/reset 1 and total reset/reset 2 inputs together. If contacts are used for the input signal, set the input signal width to 20 ms. Processing to eliminate chattering is performed for this setting.

Decimal Point Position (dp)

Decide the decimal point position for the present value, CP1/CP2 present values, set value (SV1, SV2), total count value, and dual count set value.

Prescale Value (pscl)

Pulses input to the counter are converted according to the specified prescale value. (Setting range: 0.001 to 99.999 for 6-digit models and 0.001 to 9.999 for 4-digit models.) Example: To display the feed distance for systems that output 25 pulses for a feed length of 0.5 m in the form @@.@@ m:

1. Set the decimal point position to 2 decimal places.

2. Set the prescale value to 0.02 (0.5 ÷ 25).

0.5 m

25 pulses

Encoder

• Observe the following points when setting a prescale value. Set the set value to a value less than {Maximum countable value

− Prescale value}. Example: If the prescale value is 1.25 and the counting range is

0.000 to 999.999, set the set value to a value less than 998.749 (= 999.999 − 1.25). If the set value is set to a value greater than this, output will not turn ON.

• Output will turn ON, however, if a present value overflow occurs (FFFFFF or FFFF).

Note: If the prescale value setting is incorrect, a counting error will

occur. Check that the settings are correct before using this function.

NPN/PNP Input Mode (imod)

Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. When using a two-wire sensor, select NPN input. The same setting is used for all external inputs. For details on input connections, refer to Input Connections on page page 9.

Absolute Value Setting/Forecast Value Setting (setm)

For the 2 count output mode, an absolute value setting (abs) or forecast value setting (ofst) can be set for set value 1. When a forecast value is set, specify the forecast value set value (i.e., the deviation for the set value). The forecast output (output 1) turns ON when the present value reaches the forecast value. If the forecast set value is greater than or equal to the set value, the forecast output (output 1) will turn ON as soon as counting starts.

Example: F Mode

If the total ON count of the output exceeds the alarm set value, e3 will be displayed on the Timer to indicate that the output ON count alarm value was exceeded. Refer to Self-diagnostic Function on page page 36 for information on the e3 display.

ON Count Alarm Set Values for Outputs 1 and 2 (OUT1 and OUT2) (on1a and on2a)

Set the ON count alarm values for the outputs 1 and 2. The limit can be set to between 0

× 1000 (0 times) and 9999 × 1000 (9,999,000 times). Only the underlined values are set. The alarm will be disabled if 0 is set. If the total ON count of instantaneous output 1 or 2 exceeds the alarm set value, e3 will be displayed on the Timer to indicate that the output ON count alarm value was exceeded. Refer to Self-diagnostic Function on page page 36 for information on the e3 display.

Output ON Count Monitor Value (on-c)

The monitor value is only displayed. It cannot be set. The output ON count will be 1,000 times the displayed value.

ON Count Monitor Values for Outputs 1 and 2 (OUT1 and OUT2) (on1c and on2c)

The monitor value for output 1 or 2 is only displayed. It cannot be set. The output ON count will be 1,000 times the displayed value.

• The total count value is reset when the total reset/reset 2 input is turned ON. If the Reset Key is pressed while the total count value is displayed, the total count value is reset. The present value is also reset at this time.

• The counting range of the total counter is

−99,999 to 999,999 (−999 to 9,999). The total count value returns to 0 when it reaches the full scale limit.

• The batch counter continues after count completion.

• Batch output is held until batch counter reset is input.

• When the batch counter reset input is turned ON, the batch count value is reset, and batch output turns OFF.

• If the Reset Key is pressed while the batch count value is displayed, the batch count value is reset and batch output turns OFF. The present value is also reset at this time.

• The count value can be incremented and decremented. The batch count is only incremented.

• The maximum counting speed for batch counter operation is 5 kHz. The batch counter counts the number of times the count reaches the set value.

Dual Counter Operation

Using the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed. It is possible to specify a set value for which output turns ON when the set value matches the added or subtracted result.

2. Counting is not possible for CP2 during reset 2 input. CP1 will not be affected. The dual count value will be calculated based on a CP2 present value of 0.

3. The counting range for the dual count value is −99,999 to 999,999 (0 to 9,999 for 4-digit models).

The counting ranges for the CP1 present value and CP2 present value are 0 to 999,999 (0 to 9,999 for 4-digit models). If a present value exceeds 999,999 (9,999 for 4-digit models), FFFFFF (FFFF for 4-digit models) will be displayed to indicate an overflow, and all counting will stop.

• The operation after count completion for the dual counter value is determined by the output mode.

• The CP1 present value is reset when reset 1 input is turned ON. The CP2 present value is reset when reset 2 input is turned ON.

• If the Reset Key is pressed while the dual count value, CP1 present value, or CP2 present value is displayed, all of the present values are reset and outputs turn OFF. At this time, counting is not possible for CP1 or CP2 inputs.

Tachometer Output Mode (totm)★

Set the output method for control output based on the comparison value. Upper and lower limit (HI-LO), area (AREA), upper limit (HI-HI), and lower limit (LO-LO) can be set. (For details on the output modes, refer to Output Mode Settings and Operation on page page 34.)

Counting Speed (cnts)★

Set the maximum counting speed (30 Hz/10 kHz) for CP1 input. If contacts are used for input signals, set the counting speed to 30 Hz. Processing to eliminate chattering is performed for this setting.

Decimal Point Position (dp)

Decide the decimal point position for the measurement value, OUT1 set value, and OUT2 set value.

Prescale Value (pscl)

It is possible to display the rate of rotation or the speed of a device or machine to which the H7CX is mounted by converting input pulses to a desired unit. If this prescaling function is not used, the input frequency (Hz) will be displayed. It is also possible to specify time (seconds) as the display value. Refer to Display Unit on page page 31 for details. The relationship between display and input is determined by the following equation. Set the prescale value according to the unit to be displayed.

Displayed value = f × α f: Input pulse frequency (number of pulses in 1 second) α: Prescale value

Example: To display the rate of rotation for a machine that outputs 5 pulses per revolution in the form @@.@ rpm:

• Observe the following points when setting a prescale value. Set the set value to a value less than {Maximum countable value − Prescale value}. Example: If the prescale value is 1.25 and the counting range is

0.000 to 999.999, set the set value to a value less than 998.749 (=

999.999 − 1.25). If the set value is set to a value greater than this, output will not turn ON.

* Output will turn ON, however, if a present value overflow occurs (FFFFFF or FFFF}.

Note: If the prescale value setting is incorrect, a counting error will

occur. Check that the settings are correct before using this function.

Averaging Method (avgt) (Only for Tachometer Operation)

A simple average or moving average can be selected for the averaging. With the moving average method, the average of the measurement values is displayed each sampling cycle, in contrast to a simple average, with which the the average of the set number of samples is displayed.

Number of Averaging Times (avgn)★

Flickering display and output chattering can be prevented using average processing. Average processing can be set to one of four levels: no average processing, 2 times (i.e., the average of 2 measurement values), 4 times, 8 times, or 16 times. The measurement cycle will be equal to the sampling cycle multiplied by the average processing setting (i.e., the number of times). Average processing enables stable displays even for fluctuating input signals. Set the optimum number of times for the application.

Auto-zero Time (auto0)

The display can be force-set to 0 if there is no pulse for a certain period of time. This time is called the auto-zero time. Set the auto-zero time to a time slightly longer than the estimated interval between input pulses. Accurate measurement is not possible if the auto-zero time is set to a time shorter than the input pulse cycle. Setting a time that is too long may also result in problems, such as a time-lag between rotation stopping and the alarm turning ON. The auto-zero time is not applied to pulse width measurements.

Startup Time (stmr)

To prevent undesired outputs resulting from unstable inputs immediately after the power supply is turned ON, it is possible to prohibit measurement for a set period of time, the startup time. It can also be used to stop measurements and disable outputs until the rotating body reaches the normal rate of rotation, after the power supply to the H7CX and rotating body are turned ON at the same time.

Key Protect Level (kypt)

Set the key protect level. Refer to Key Protect Level on page page 36.

Pulse Cycle Measurement/Pulse Width Measurement (calm)

Set the measurement mode to pulse cycle measurement or pulse width measurement. With pulse cycle measurement, the number of pulse cycles that occur in 1 s is measured. With pulse width measurement, the ON time for one pulse is measured. An input OFF period of at least 20 ms is required for pulse width measurement. If there is no input pulse during pulse width measurement, the previously measured value will be held.

Display Unit (unit)

When pulse cycle measurement is used, set the display unit to Hz (hertz) or s (seconds).

Counting Interval (intv)

If the measurement speed is 10 kHz when pulse cycle measurement is used, set the measurement interval to 200 ms or Cont (10 ms min.).

Note: Depending on the operating environment, the condition

of resin or rubber products may deteriorate, or they may shrink or become harder. Therefore, it is recommended that resin products be replaced regularly.

Soft Cover

Y92A-48F1

Protecting the Timer in Environments Subject to Oil

The H7CX's panel surface is water-resistive (conforming to IP@6, UL Type 4X) and so even if drops of water penetrate the gaps between the keys, there will be no adverse effect on internal circuits. If, however, there is a possibility of oil being present on the operator's hands, use the Soft Cover. The Soft Cover ensures protection equivalent to IP54 against oil. Do not, however, use the H7CX in locations where it would come in direct contact with oil.

Hard Cover

Y92A-48

Flush Mounting Adapter

Y92F-30

Order a Flush Mounting Adapter separately if the product is to be flush-mounted.

Y92F-45

Use this Adapter to install the Counter/Tachometer in a cutout previously made for a DIN 72 × 72 mm device (panel cutout: 68 × 68 mm).

Waterproof Packing

Y92S-29

Order the Waterproof Packing separately if it is lost or damaged. The Waterproof Packing can be used to achieve protection equivalent to IP66. (The Waterproof Packing will deteriorate, harden, and shrink depending on the application environment. To ensure maintaining the NEMA4 waterproof level, periodically replace the Waterproof Packing. The periodic replacement period will depend on the application environment. You must confirm the proper replacement period. Use 1 year or less as a guideline. If the Waterproof Packing is not replaced periodically, the waterproof level will not be maintained.) It is not necessary to mount the Waterproof Packing if waterproof construction is not required.

Explanation of Functions

Basic Functions

Input Mode

The mode can be switched between tachometer mode and AMDcompatible mode.

Tachometer Mode

Use this mode to measure the pulse frequency (Hz).

AMD-compatible Mode

Use this mode to measure the pulse cycle (s).

Cycle (s)

Counting Speed

Set the maximum counting speed (30 Hz/10 kHz) for input. If contacts are used for input signals, set the counting speed to 30 Hz. Processing to eliminate chattering is performed for this setting.

Output Mode

Set the output method for control output based on the comparison value. Upper and lower limit (HI-LO), area (AREA), upper limit (HI), and lower limit (LO) can be set. For the H7CX-RW@, the upper limit (HIHI) and lower limit (LO-LO) can be set. (For details on the operation of the output modes, refer to Output Mode Settings on page page 49.)

Averaging Method (avgt)

Simple averaging or a moving average can be selected for the averaging method. With a moving average, the average measurement value is displayed every sampling cycle or pulse cycle, in contrast to simple averaging, for which the average value is displayed for the set number of samples.

Number of Averaging Times

Flickering display and output chattering can be prevented using average processing. Average processing can be set to one of four levels: no average processing, 2 times (i.e., the average of 2 measurement values), 4 times, or 8 times. For a measurement frequency of 5 Hz or higher using a tachometer, the average will be equal to the sampling cycle (200 ms) multiplied by the averaging setting (i.e., the number of times). For less than 5 Hz, the frequency will be measured when the input pulse comes. Average processing produces a stable display even for fluctuating input signals. Set the optimum number of times for the application. If AMD-compatible mode is used, the measurement cycle will be measured when the input pulse is received. The output will change, however, when the comparison value is exceeded even if averaging is enabled.

NPN/PNP Input Mode

Advanced Functions

Decimal Point Position (dp)

Decide the decimal point position for the measurement value and comparison value.

Prescale Value (pscl)

It is possible to display the rate of rotation or the speed of a device or machine to which the H7CX is mounted by converting input pulses to a desired unit. If the default prescaling value (1,000) is used, the input frequency (Hz) will be displayed. The relationship between display and input is determined by the following equation. Set the prescale value according to the unit to be displayed. Displayed value = f × α f: Input pulse frequency (number of pulses in 1 second) α: Prescale value

(1) Displaying Rotation Rate

Display unit Prescale value (α)

rpm 1/N × 60

rps 1/N

N: Number of pulses per revolution

Example: In order to display the rate of rotation for a machine that outputs 5 pulses per revolution in the form @@.@ rpm:

1. Set the decimal point position to 1 decimal places.

2. Using the formula, set the prescale value (α) to 1/N × 60 = 60/5 = 12.

(2) Displaying Speed

Display unit Prescale value (α)

m/min πd × 1/N × 60

m/s πd × 1/N

N: Number of pulses per revolution d: Diameter of rotating body (m) πd: Circumference (m)

• Observe the following points when setting a prescale value. Set the set value to a value less than {Maximum countable value

− Prescale value}. Example: If the prescale value is 1.25 and the counting range is

0.000 to 999.999, set the set value to a value less than 998.749 (= 999.999 − 1.25). If the set value is set to a value greater than this, output will not turn ON.

Note: If the prescale value setting is incorrect, a counting error will

occur. Check that the settings are correct before using this function.

Auto-zero Time (auto0)

It is possible to make the settings so that the frequency will be forceset to 0 if there is no pulse for a specified period of time. This time is called the auto-zero time.

d: Diameter

of rotating body (m)

Note: Set the auto-zero time to a time slightly longer than the

estimated interval between input pulses. It will not be possible to make accurate measurements if the auto-zero time is set to a time shorter than the input pulse cycle. Setting a time that is too long may also result in problems, such as a time-lag between rotation stopping and the alarm turning ON.

Page 46

H7CX-R@-N

Startup Time (stmr)

In order to prevent undesired output resulting from unstable input immediately after the power supply is turned ON, measurement can be prohibited for a set time at startup. It can also be used to stop measurement and disable output until the rotating body reaches the normal rate of rotation, after the power supply to the H7CX and rotating body are turned ON at the same time.

Peak/bottom Hold Enabled (dhld)

This function records the peak and bottom (i.e., minimum) values after counting starts (after turning ON the power supply or changing the configuration selection mode or function setting). The peak value is also held when the power supply is interrupted.

H7CX-@-N

Safety Precautions for All H7CX Series (Common)

CAUTION

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.

Minor injury due to explosion may occasionally occur. Do not use the Counter where subject to flammable or explosive gas.

Fire may occasionally occur. Tighten the terminal screws to the rated torque. H7CX 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 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.

• 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 terminals.

• 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.

Sensor

Diode

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 electric shock, fire, or malfunction may occasionally occur. Do not disassemble, modify, or repair the Counter or touch internal components.

Precautions for Safe Use

• The panel surface of the H7CX-A/-R is water-resistant (conforming to NEMA4, IP66, UL Type 4X (Indoor Use Only). To protect the internal circuits from water penetration through the space between the H7CX and operating panel, waterproof packing is included. Attach the Y92F-30 Adapter with sufficient pressure with the reinforcing screws so that water does not penetrate the panel.

0.5 to 1 mm

It is recommended that the space between the screw head and the Adapter be

0.5 to 1 mm.

• 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 in the following locations:

• Locations subject to sudden or extreme changes in temperature.

• Locations where high humidity may result in condensation.

• Do not use the Counter outside of the rated ranges for vibration, shock, water exposure, and oil exposure.

• 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.

Input0 V

• Use a switch, relay, or other contact so that the rated power supply voltage will be reached within 0.1 seconds. 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 H7CX uses a constant read-in system, output will turn ON if the set value is equal to the present value.

• When changing the comparison value during operation, because the H7CX uses a constant read-in system, the output status will change if the comparison value is changed to a value on the other side of 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.

• When the power is turned ON using the factory settings, the output will turn ON after 999.9 s if no pulses are received as count input.

• 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 LED, 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.

Page 53

H7CX-@-N

Precautions for Correct Use

• H7CX models with a 12 to 24-VDC power supply use a transformer-free power supply method in which the power supply terminals are not isolated from the signal input terminals. If a nonisolating DC power supply is used, unwanted current paths may occasionally burn or destroy internal components depending on the wiring. Always check the wiring sufficiently before use.

• 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.

• Maintain voltage fluctuations in the power supply within the specified operating voltage range.

• When turning the power ON and OFF, input signal reception is possible, unstable, or impossible as shown in the diagram below.

Power

supply

OFF

200 ms 5 ms0 to 90 ms 0 to 1 s

Input Impossible

• 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 24 VDC power supply, reduce the load with the power supply voltage, as shown in the following diagram (DC power supplies only).

100

Load current (mA)

Conformance to EN/IEC Standards

• When conforming to EMC standards, refer to the information provided in this datasheet for cable selection and other conditions.

• This is a class A product. In residential areas it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference.

•H7CX-A@-N: Basic insulation is provided between power supply and input terminals, between power supply and output terminals, and between input and output terminals. (However, no insulation is provided between the power supply and input terminals for the H7CX-A@D-N.)

•H7CX-R@-N: Basic insulation is provided between power supply and input terminals and between input and output terminals.

• When double insulation or reinforced insulation is required, apply double insulation or reinforced insulation as defined in IEC 60664 that is suitable for the maximum operating voltage with clearances or solid insulation.

• Connect the input and output terminals to devices that do not have any exposed charged parts.

10.8

Power supply voltage (VDC)

• 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).

• EEPROM is used as backup memory when the power is interrupted. The write life of the EEPROM is 100,000 writes. The EEPROM is written at the following times:

• When the power supply is turned OFF

• When switching from Configuration Selection Mode or Function Setting Mode to Run Mode

• Dispose of the product according to local ordinances as they apply.
