Soft Cover Y92A-48F1

Note: 1.

Depending on the operating environment, the condition of the Soft Cover may deteriorate, and it may shrink or become harder. Therefore, it is recommended that the Soft Cover is replaced regularly.

The H7CX’s panel surface is water-resistive (conforming to

IP66) 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.

!Caution

Do not use the product in locations subject to flammable or explosive gases. Doing so may result in explosion.

The service life of the output relays depends on the switching capacity and switching conditions. Consider the actual application conditions and use the product within the rated load and electrical service life. Using the product beyond its service life may result in contact deposition or burning.

Do not disassemble, repair, or modify the product. Doing so may result in electric shock, fire, or malfunction.

Do not allow metal objects or conductive wires to enter the product. Doing so may result in electric shock, fire, or malfunction.

External Power Supply

■

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).

Transistor Output

■

The transistor output of the H7CX is isolated from the internal circuitry by a photocoupler, so the transistor output can be used as both NPN and PNP output.

NPN output PNP output

Load Load

supply

OFF

200 ms 5 ms

Input Impossible

Unstable

Turn the power ON and OFF using a relay with a rated capacity of 10 A minimum to prevent contact deterioration due to inrush current caused by turning the power ON and OFF.

Apply the power supply voltage through a relay or switch in such a way that the voltage reaches a fixed value immediately, otherwise they may not be reset or a counter error may result.

Be sure that the capacity of the power supply is large enough, otherwise the counter may not start due to inrush current (reference value: approx. 10 A, 1.2 ms at 26.4 VAC) that may flow for an instant when the counter is turned ON.

Make sure that the fluctuation of the supply voltage is within the permissible range.

Make sure that the voltage applied is within the specified range, otherwise the internal elements of the counter may be damaged.

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.

Operation with a Set Value and

■

Present Value of 0

If the set value and present value are both 0, output will turn ON. Output will turn OFF during reset.

Using the Prescaling Function

■

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

If the set value is set to a value greater than this, output will not turn

•

ON.

Note:

Setting the prescale value incorrectly may result in incorrect count-

•

ing operation. Be sure to set the prescale value correctly.

■

Ensure that the power is turned OFF before changing DIP switch settings. Changing DIP switch settings with the power turned ON may result in electric shock due to contact with terminals subject to high voltages.

■

All data is stored in the EEPROM when there is power failure. The EEPROM can be overwritten more than 100,000 times. EEPROM is overwritten when the power is turned OFF or when settings are changed.

0.000 to 999.999, set the set value to a value less than

998.749 (= 999.999 − 1.25).

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

Wiring

■

Wiring input lines in the same conduit as power lines or other highvoltage lines may result in malfunction due to noise. Wire the input lines separately, away from lines carrying high-voltages. In addition, make the input wiring as short as possible and use shield lines or metal wiring conduits.

Pay attention to terminal polarity to ensure correct wiring.

Mounting

■

Tighten the two mounting screws on the Adaptor. Tighten them alternately, a little at a time, so as to keep them at an equal tightness.

The H7CX’s panel surface is water-resistive (conforming to NEMA 4 and IP66). In order to prevent the internal circuit from water penetration through the space between the timer and operating panel, attach a waterproof packing between the timer and installation panel and secure the waterproof packing with the Y92F-30 Flush-mounting Adapter.

0.5 to 1 mm

It is recommended that the space between the screw head and the adapter should be

Operating Environment

■

Use the product within the ratings specified for submerging in water

•

and exposure to oil. Do not use the product in locations subject to vibrations or shocks.

•

Using the product in such locations over a long period may result in damage due to stress.

Do not use the product in locations subject to dust, corrosive

•

gases, or direct sunlight. Separate the input signal devices, input signal cables, and the

•

•

using the product in an environment where a large amount of static electricity is produced (e.g., forming compounds, powders, or fluid materials being transported by pipe).

Organic solvents (such as paint thinner), as well as very acidic or

•

basic solutions might damage the outer casing of the H7CX. Use the product within the ratings specified for temperature and

•

humidity. Do not use the product in locations where condensation may occur

•

due to high humidity or where temperature changes are severe. Store at the specified temperature. If the H7CX has been stored at

•

a temperature of less than -10°C, allow the H7CX to stand at room temperature for at least 3 hours before use.

uses

Input Mode (

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 112.)

Dual Count Calculating Mode (

When using as a dual counter, select either ADD (addition) or SUB (subtraction) as the calculation method for the dual count value. SUB mode can be used only when K-2, D, L, or H is selected as the output mode with 6-digit models.

ADD: Dual count value = CP1 PV + CP2 PV

SUB: Dual count value = CP1 PV − CP2 PV

Output Mode (

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 113.)

One-shot Output Time (

switch.)

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 (

) (Setting possible using

otm2

DIP switch.)

When using as a 2-stage counter or batch counter, 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 (

When using as a 2-stage counter, 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, cannot be set when the output mode is K-2.

Counting Speed (

switch.)

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 (

) (Setting possible using

iflt

DIP switch.)

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 input signals, set the counting speed 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 (

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).

Note: 1.

The batch count value is held at 0 during batch counter reset input. If the batch count set value is 0, batch count will be performed but there will be no batch output.

The batch count value returns to 0 when it reaches 999,999 (9,999 for 4-digit models).

Once batch input has been turned ON, it will return to the ON state after power interruptions.

If the batch count set value is changed from a value that is greater than the batch count value to one that is less, batch output will turn ON.

After batch output turns ON, the ON state will be held even if the batch count set value is changed to a value greater than the batch count

value.

Explanation of Functions

Tachometer Output Mode (

) (Setting possible using

totm

DIP switch.)

Set the output method for control output based on the OUT1/OUT2 set 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 operation of the output modes, refer to Output Mode Settings on page 123.)

Counting Speed (

) (Setting possible using DIP

cnts

switch.)

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 (

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.

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

Displaying Rotation Rate

Example:In order to display the rate of rotation for a machine that

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

outputs 5 pulses per revolution in the form @@.@rpm:

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

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

Flickering display and output chattering can be prevented using average processing (simple averaging). 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. The measurement cycle will be equal to the sampling cycle (200 ms) multiplied by the average processing setting (i.e., the number of times). Average processing enables fluctuating input signals to be displayed stably. Set the optimum number of times for the application.

Auto-zero Time (

It is possible to set the H7CX so that if there is no pulse for a certain time the display is force-set to 0. 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 and within the setting range (0.1 to 99.9 s). 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.

Startup Time (

In order to prevent undesired output resulting from unstable input immediately after the power supply is turned ON, it is possible to prohibit measurement for a set time (0.0 to 99.9 s), the startup time. 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.
