Safety Precautions
Definition of Precautionary Information
Indicates a potentially hazardous situation which,
Caution if not avoided, may result in minor or moderate injury
or in property damage.
Precautions
Caution
Minor injury due to electric shock may occasionally occur. Do
not touch any of the terminals while power is being supplied.
Fire may occasionally occur. Tighten the terminal screws to
a torque of 0.5 to 0.6 N ⋅ m (4.4 to 5.3 in-lb).
Minor injury due to explosion may occasionally occur. Do not
use the Counter where subject to flammable or explosive gas.
If the output relay is used beyond its life expectancy, its
contacts may become fused or there may be a risk of fire.
Use the output relay within its rated load and electrical life
expectancy. The life expectancy of the output relay varies
considerably according to its usage.
Minor electric shock, fire, or malfunction may occasionally
occur. Never attempt to disassemble, modify, or repair the
Counter or touch any of the internal parts.
Precautions for Safe Use
Operating Environment
• The Counter is intended for indoor use only. Do not use the Counter
outdoors or in any of the following locations.
• Locations subject to sudden or extreme changes in temperature.
• Locations where high humidity may result in condensation.
• Locations subject to direct sunlight.
• Locations subject to corrosive gas.
• Locations subject to excessive dust or dirt.
• This is a class A product (for industrial environments). In residential
areas, it may cause radio interference, in which case the user may be
required to take adequate measures to reduce interference.
• Use the Counter within the specified ratings for operating temperature
and humidity. Temperature rise may shorten the service life of the Counter
if it is used near a power supply or other heat-generating objects.
• Use the Counter within the specified ratings for vibrations, shock, and
splashing water.
• The Counter is not oil resistant. Do not use it in locations subject to oil.
• Install the Counter well away from any sources of excessive static
electricity, such as pipes transporting molding materials, powders, or
liquids.
• Store the Counter within the specified ratings. If the Counter has been
stored at temperatures of −10°C or lower, let it stand for 3 hours or longer
at room temperature before turning ON the power supply.
Power Supply
• Maintain voltage fluctuations in the power supply within the specified
range.
• Internal elements may be destroyed if a voltage outside the rated voltage
is applied.
• When the power is turned ON, an inrush current will flow for a short time
(approx. @.@ A for @.@ ms). Depending on the power supply capacity,
operation may not start. Be sure to use a power supply with a sufficient
capacity.
• Use a commercial power supply as the AC power supply for the Counter.
Using an inverter output with an output frequency of 50/60 Hz as the
power supply may cause the Counter to produce smoke or become
damaged by burning.
• Use a switch, relay, or other device with contacts so that the rated power
supply voltage will be reached within 2 s. If the power supply voltage is
not reached quickly enough, the outputs may malfunction.
• Use a switch, relay, or other device with contacts to turn the power supply
OFF instantaneously. Outputs may malfunction and memory errors may
occur if the power supply voltage is decreased gradually.
Installation and Wiring
• To mount the Counter to a panel, attach the two supplied brackets to the
left and right sides of the Counter, and securely tighten the knurled
screws on the brackets by hand, maintaining a balance between them.
Damage may result if the knurled screws are excessively tightened
with pliers or other tools.
• Be sure to wire the terminals correctly.
• Up to two wires of the same size and type can be inserted into a single
terminal.
• Do not connect more than two crimp terminals to each Counter terminal.
• Use the specified wires for wiring.
Applicable wire: AWG 24 to AWG 18
(equal to a cross-sectional area of 0.20 to 0.82 mm
Solid wire or twisted wire (copper)
• Separate the Counter, the devices that generate input signals, and input
signal wires from any potential sources of noise, such as high-voltage
lines.
Handling
• Do not use organic solvents (such as paint thinner or benzine),
strong alkaline, or strong acids because they will damage the
external finish.
• Approximately 14 V will be output to the input terminals when the
Counter is used with the key protection input terminals and no-voltage
input (NPN input) are used. To prevent charging accidents, connect
a diode to the power supply circuit of input devices if input devices are
used with a power supply of less than 14 V.
• Do not connect loads that exceed the rated output current. The
output elements may be destroyed, possibly resulting in short-circuit
or open-circuit faults.
• When using heaters, be sure to use a thermal switch for the load circuit.
• Always connect a diode to protect against counter electromotive
force when using an inductive load. Counter electromotive force may
destroy output elements, possibly resulting in short-circuit or open-
circuit faults.
• Install a switch or circuit breaker that allows the operator to immedia-
tely turn OFF the power, and label it to clearly indicate its function.
• Check that the display (backlight and LCD) is operating normally.
Some operating environments may accelerate deterioration of the
indicators, LCD, and resin components and cause display malfunctions.
Periodically inspect and replace parts.
Precautions for Correct Use
• Inrush current generated by turning ON or OFF the power supply may
deteriorate contacts in the power supply circuit. Turn ON or OFF using
a device with a rated current of 10 A or higher.
• Inputs signals may be accepted, not accepted, or unstable for the
following times when the power supply is turned ON or OFF.
Set the system to allow leeway in the timing of input signals.

stable
• This Counter always compares the count value with the set value. Thus,
if you change the set value during operation, please remember that the
output will turn ON when the set value becomes equal to the count
value.
• With the factory setting, the output will turn ON when power is supplied
to the Counter because the set value and count value are both zero.
During resetting, however, the output stays OFF.
• 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
settings are changed, or the power is tuned OFF.
• Water resistance will be lost if the front sheet is peeled off or torn.
Do not use the Counter if the front sheet is missing or torn.
• Abide by all local ordinances and regulations when disposing of
the Counter.
Conformance to EN/IEC Standards
Power supply, input, and output terminals have basic insulation between
them. When double insulation is required, apply supplemental insulation
defined in IEC 60664 that is suitable for the maximum operating voltage
with clearances or solid insulation.
