Self-diagnostic Functions
For details, refer to the latest datasheet (Cat. No. M079).
1) H7CZ 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 non-isolating 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.
2) 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.
3) Maintain voltage fluctuations in the power supply within the specified
operating voltage range.
4) To allow for the startup time of peripheral devices (e.g., sensors), start
Counter timing operation 200 ms to 290 ms after turning ON the
power. The input signal will not be accepted before 200 to 290 ms has
elapsed.
5) The input signal will not be accepted after 5 to 1005 ms has elapsed
from when the power supply is turned OFF.
6) 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.
7) 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 diagram
(DC power supplies only) on the right.
8) If the prescale value setting is incorrect, a
counting error will occur. Check that the
settings are correct before using this function.
9) 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.
10) 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).
11) EEPROM is used as memory when the power is interrupted. The write
life of the EEPROM is 100,000 writes. The EEPROM is written when
the power is turned OFF or when switching from function setting mode
to run mode.
12) Dispose of the product according to local ordinances as they apply.
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.
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.
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.
1) 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.
2) 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.
3) Mounting the Counter side-by-side may reduce the life expectancies of internal
components.
4) Use the Counter within the specified ranges for the ambient operating
temperature and humidity.
5) Do not use in the following locations:
•Locations subject to sudden or extreme changes in temperature.
•Locations where high humidity may result in condensation.
•Locations with excessive vibration or shock.
•Locations subject to water.
•Locations subject to oil.
6) Do not use the Counter outside of the rated ranges for vibration, shock, water
exposure, and oil exposure.
7) Do not use this Counter in dusty environments, in locations where corrosive gasses
are present, or in locations subject to direct sunlight.
8) Install the Counter well away from any sources of static electricity, such as pipes
transporting molding materials, powders, or liquids.
9) Internal elements may be destroyed if a voltage outside the rated voltage range
is applied.
10) Separate the Counter from sources of noise, such as devices with input signals
from power lines carrying noise, and wiring for I/O signals.
11) Do not connect more than two crimp terminals to the same terminal.
12) Up to two wires of the same size and type can be inserted into a single terminals.
13) Use the specified wires for wiring. Applicable Wires: AWG 18 to AWG 22, solid
or twisted, copper
14) Install a switch or circuit breaker that allows the operator to immediately turn
OFF the power, and label it to clearly indicate its function.
15) Approximately 14 V is output from the input terminals. Use a sensor that
contains a diode.
16) 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.
17) 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.
18) When changing the set value during operation, because the H7CZ uses a
constant read-in system, output will turn ON if the set value is equal to the
present value.
19) 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.
20) Do not use organic solvents (such as paint thinners or benzine), strong alkali, or
strong acids. They will damage the external finish.
21) Confirm that indications are working normally, including the LCD. The indicator
LCD and resin parts may deteriorate more quickly depending on the application
environment, preventing normal indications. Periodic inspection and
replacement are required.
22) The waterproof packing may deteriorate, shrink, or harden depending on the
application environment. Periodic inspection and replacement are required.
•When conforming to EMC standards, refer to the information
provided in this Instruction Manual 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.
•Basic insulation is provided between power supply and input
terminals, between power supply and output terminals, and
between input and output terminals. (No insulation is provided
between the power supply and input terminals for the
H7CZ-L8D1.)
•Basic insulation is provided between power supply and output
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.
