Note: 1. Depending on the operating environment, the condition of

resin products may deteriorate, and may shrink or become harder. Therefore, it is recommended that resin products are replaced regularly.

2. 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, howe ver, 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.

Multifunction Preset Count er H7CX-A (Counter Function) 19

Explanation of Functions

Input Mode (cntm) (Setting possible using DIP switch.)

Set increment mode (UP), decrement mode (D OWN), 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 page23.)

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. 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 (outm) (Setting possible using DIP s witch.)

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. Out put 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 24.)

One-shot Output Time (otim) (Setting possible using DIP 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 (otm2) (Setting possible using 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 (otm1)

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, hold is displayed, and outputs are held. HOLD cannot be set when the output mode is K-2.

Counting Speed (cnts) (Setting possible using DIP 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 (iflt) (Setting possible using 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 (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

0.5 m

Encoder

÷25).

25 pulses

NPN/PNP Input Mode (imod)

Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. The same setting is used for all external inputs. For details on input connections, refer to Input Connections on page 11.

Display Color (colr)

Set the color used for the present value.

Output OFF (See note.) Output ON (See note.)

red Red (fixed) grn Green (fixed) r-g Red Green g-r Green Red

Note: When using as a 2-stage counter, this is the status of output 2.

Output Allocation (otst)

When using H7CX-AU@ models as a 2-stage counter, the output can be flexibly allocated to either stage 1 or 2. Transistor output can be allocated to SV1 and contact output for SV2 or vice verse, as in the following table.

Multifunction Preset Count er H7CX-A (Tachometer Functi on) 31

Explanation of Functions

Tachometer Output Mode (totm) (Setting possible using 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 35.)

Counting Speed (cnts) (Setting possible using DIP 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 (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.

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 f: Input pulse frequency (number of pulses in 1 second) a:Pr escale value

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:

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

πd × 1/N × 60 πd × 1/N

× 60 =

d: Diameter of

rotating body

Average Processing (aug) (Setting possible using DIP switch.)

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 (aut=)

It is possible to set the H7CX so that if t here is no pulse for a certain time the display is force-set to 0. This time is called the auto-zero time.

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

ed 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 (stmr)

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.

■Operation in Configuration Selection Mode

Select which H7CX configuration is used (i.e., 1-stage counter, 2-stage counter, total and preset counter, batch counter, dual counter, or tachometer) in configuration selection mode. The H7CX is also equipped with a DIP switch monitor function, a convenient function that enables the settings of the DIP switch pins to be confirmed using the front display.

To change the mode to configuration selection mode, press

the Key for 1 s min. with the key held down. The mode will not change if the key is pressed first.

Select the configuration using the keys. ( key only for 6digit models) The H7CX is factory-set to the 1-stage counter configuration (2-stage counter configuration with H7CX-AW@/-A4W@ models).

(1-stage counter) (2-stage counter) (Dual counter)(Batch counter) (Tachometer)(Total and

preset counter)

The configuration that can be selected depend on the model.

The status of the DIP switch pins (1 to 8) can be confirmed using the keys.

Note: This display is possible only if DIP switch pin 1 (DIP switch set-

tings) is set to ON (i.e., enabled).

Example

Indicates that DIP switch pin 6 is ON. Indicates that DIP switch pin 5 is OFF. Indicates that DIP switch pin 4 is ON. Indicates that DIP switch pin 3 is OFF. Indicates that DIP switch pin 2 is ON. Indicates that DIP switch pin 1 is ON.

Note: 1. When the mode is changed to configuration selection mode, the present value is reset, outputs turns OFF, and counting (measur ing)

stops.

2. Setting changes made in configuration selection mode are enabled when the mode is changed to run mode. If the configuration is changed, the set value (or set value 1 and set value 2), OUT1 set value or OUT2 set value are initialized.

■Explanation of Functions

Basic Functions

(setting is performed with DIP switch)

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 details on the operation of the output modes, refer to Output Mode Settings on page 55.)

Average Processing

NPN/PNP Input Mode

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 47.

Advanced Functions

(setting is performed with operation keys)

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-R is mounted by converting input pulses to a desired unit. If this prescaling function is not used, the input f requency (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 f: Input pulse frequency (number of pulses in 1 second) a:Pr escale value

Auto-zero Time (aut=)

It is possible to set the H7CX-R 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.

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

ed interval between input pulses and within the setting range (0.1 to 999.9 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.

Safety Precautions (Common)

Note: The following precautions are common for all H7CX models.

CAUTION

Loose screws may occasionally result in fire or malfunction. Tighten the terminal screws securely. The recommended tightening torque is 0.5 N·m.

There may occasionally be a risk of explosion. Do not use the product where flammable or combustion gases are present.

If the output relay is used beyond its life expectancy, its contacts may occasionally become fused or there may occasionally be a risk of fire. 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.

This may occasionally cause electric shock, fire or malfunction. Never disassemble, repair or modify the product.

This may occasionally cause electric shock, fire or malfunction. Do not allow metal fragments or lead wire scraps to fall inside this product.

■Precautions for Safe Use

Operating and Storage Conditions

• Do not use in locations affected by excessive vibration or shock, or

in locations subject to exposure to water or oil.

• 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 product from the source of noise or high-tension cables producing noise.

• Separate the product from the source of static electricity when 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 temperature for at least 3 hours before use.

°C, allow the H7CX to stand at room

• Lea ving the H7CX with outputs ON at a high temperature f or a long time may hasten the degradation of internal parts (such as electrolytic capacitors). Therefore, use the product in combination with relays and avoid leaving the product as long as more than 1 month with the output turned ON.

X1/aX2/b T/a X1/a

X1T X2

• When the product is operated with no-voltage input (NPN input), approximately 14 V is output from the input terminals, so connect a diode if the external power supply is less than 14 V.

Sensor

• Install a switch or circuit-breaker that allows the operator to immediately turn OFF the power, and make sure it is labeled clearly.

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

0.5 to 1 mm

• Tighten the two mounting screws on the Adapter. Tighten them alternately, a little at a time, so as to keep them at an equal tightness. If the panel screws are tightened unequally, water may ingress inside the panel.

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

0.5 to 1 mm.

Input0 V

Auxiliary relay (e.g., MY Relay)

Usage Precautions

• Make sure that the voltage applied is within the specified range,

otherwise the internal elements of the counter may be damaged.

• The load current must be within the rated current.

• 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.

• Pay attention to terminal polarity to ensure correct wiring.

• Make sure that the fluctuation of the supply voltage is within the

permissible range.

• Apply the power supply voltage through a relay or switch in such a way that the voltage reaches the rated value within 2 s. If the voltage is applied gradually, the power may not be reset or unstable output operations may result.

• Set each set value to match the item being counted (or measured). Not matching the content of the set values with the counted (or measured) items may cause unexpected operations resulting in injury or damage to the equipment.

Safety Precautions H7CX Series 59

■Precautions fo r Correct Use

External Power Supply

The capacity of the external power supply is 100 mA at 12 V. When using a 24 VA C/12 to 24 VDC pow er supply, reduce the load with the power supply voltage, as shown in the following diagram (DC power supplies only).

(DC voltage supply only)

100

Load current (mA)

10.8

Power supply voltage (VDC)

Power Suppies

• 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.

• Be sure that the capacity of the power supply is large enough, otherwise the H7CX may not start due to inrush current (reference value: approx. 10 A, 1.5 ms at 26.4 VAC) that ma y flow for an instant when the H7CX is turned ON.

Power Failure Backup

All data is stored in the EEPROM when there is a 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.

■Conformance to EN/IEC

Standards

• Specifications call for basic insulation between the power supply

and input terminals, between the power supply and output terminals, and between the input and output terminals. (The H7CXA@D is not insulated between the power supply and input terminals.)

• Input and output terminals are connected to devices without exposed charged parts.

• Input and output terminals are connected to devices with basic insulation that is suitable for the maximum operating voltage.
