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.
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, 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.

Precautions
■ Transistor Output
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.
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
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.
Load
Load
+
+
Power for load
Power for load
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 H7CX.
■ 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).

■ Changing the Set Values
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.

• Set the set value to a value less than {Maximum countable value −

Example: If the prescale value is 1.25 and the counting range is

998.749 (= 999.999 − 1.25).

200 ms 0 to 90 ms 5 ms
■ Using the Prescaling Function
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.
• If the set value is set to a value greater than this, output will not turn
ON.
Note: Output will turn ON, however, if a present value overflow occurs
(FFFFFF or FFFF).
• Setting the prescale value incorrectly may result in incorrect counting operation. Be sure to set the prescale value correctly.
■ DIP Switch Setting
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.
■ Power Failure Backup
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.

Pay attention to terminal polarity to ensure correct wiring.
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 following table shows the delay from when the present value
passes the set value until the output is produced.
Transistor output
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.

Counters
• 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
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°C, allow the H7CX to stand at room
temperature for at least 3 hours before use.
• Leaving the H7CX with outputs ON at a high temperature for 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.

• The load current must be within the rated current.
■ Insulation
• 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 [email protected]
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.

Explanation of Functions
Input Mode (cntm) (Setting possible using DIP switch.)
Prescale Value (pscl)
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.)
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.)
1. Set the decimal point position to 2 decimal places.
Dual Count Calculating Mode (calm)
2. Set the prescale value to 0.02 (0.5÷25).
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
0.5 m
Output Mode (outm) (Setting possible using DIP switch.)
25 pulses
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 (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.)
Encoder
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 Connection on
page 96.

Output Allocation (otst)
When using [email protected] 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 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.

Key Protect Level (kypt)
Set the key protect level.
When the key-protect switch in set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the

Note: The full scale (FS) for H7CX 4-digit models is 9999.
• The total counter continues to count the
total accumulated value when the present
value is reset using reset/reset 1 input
(reset key).
• 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.
Batch Counter Operation
The H7CX has a batch counter, separate from the 1-stage preset counter, for counting the number of times the count has been completed.
• 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 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.

H7CX (Tachometer Function)
C-119
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 123.)
Counting Speed (cnts) (Setting possible using DIP
switch.)
Auto-zero Time (aut=)
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 (stmr)
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.
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.
Prescale Value (pscl)
Display
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.
Startup time
Comparison

The relationship between display and input is determined by the following equation. Set the prescale value according to the unit to be
displayed.

2. If the tachometer output mode is set to AREA, however, the
measured value is displayed in green when control output 1
is OFF and in red when control output 1 is ON.
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.
