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.

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.
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.
Set the key protect level.
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of cer tain operation keys by specifying the
key protect level (KP-1 to KP-5). The key protect indicator is lit while the key-protect switch is set to ON. Confirm the ON/OFF status of the keyprotect switch after the H7CX is mounted to the panel.

After making DIP switch settings for basic operations, advanced-functions (see note) can be added using the operation keys.
For details, refer to page 31.
Note: Advanced functions consist of decimal point position, prescale value, auto-zero time, startup time, display color, output allo-
Note: When using as a tachometer, switch to the tachometer configuration using the procedure given on page 36.
Settings that cannot be performed with the DIP switch are performed with the operation keys.

Note: 1. If the mode is switched to the function setting mode during operation, operation will

2. Changes made to settings in function setting mode are enabled for the first time when
the mode is changed to run mode. Also, when settings are changed, the counter is reset (measured values initialized and output turned OFF) on returning to run mode.
For details on operations in run mode, refer to page 34.
The characters displayed in reverse video are the initial values.
When performing settings with operation keys only, set pin1 of the DIP switch to OFF (factory setting).
If pin 1 of the DIP switch is set to ON, the setting items indicated by will not be displayed.
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.

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.

■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
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.
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.

πd × 1/N
d: Diameter of
rotating body
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.
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-R and rotating body are turned O N at the same
time.

Key Protect Level (kypt)
Set the key protect level.
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of cer tain operation keys by specifying the
key protect level (KP-1 to KP-5). The key protect level is set in the function setting mode. The key protect indicator is lit while the key-protect
switch is set to ON. Confirm the ON/OFF status of the key-protect switch after the H7CX is mounted to the panel.

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/bT/aX1/a
X
X1TX2
• 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 PrecautionsH7CX Series59
■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)
20
10.8
15
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.

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 val ue greater than this, output will not turn
ON.
Note: Output will turn ON, however, if a present value ov erflow occurs
• Setting the prescale value incorrectly may result in incorrect
counting operation. Be sure to set the prescale value correctly.
0.000 to 999.999, set the set value to a value less than

Safety Precautions (H7CX-R)
■Precautions for Safe Use
Changing the Measurement Value
The H7CX-R uses a constant read-in system, so the output status is
affected when the comparison values are changed during operation
such that the present measurement value falls within the range of the
upper- and lower-limit comparison values.
Turning ON the Power using the
Factory Settings
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.
■Precautions fo r Correct Use
Comparison Value Settings
In upper and lower limit output mode, if the comparison value setting
is such that comparison value 1
always be ON.
Using the Prescaling Function
Setting the prescale value incorrectly may result in incorrect counting
operation. Be sure to set the prescale value correctly.
≥ comparison value 2, the output will
