Safety Considerations
Please observe all safety considerations for safe and proper product operation to avoid hazards.
※
Safety considerations are categorized as follows.
※
Warning Failure to follow these instructions may result in serious injury or death.
Caution
Failure to follow these instructions may result in personal injury or product damage.
※
The symbols used on the product and instruction manual represent the following
symbol represents caution due to special circumstances in which hazards may occur.
Warning
1. Fail-safe device must be installed when using the unit with machinery that may cause serious injury
or substantial economic loss. (e.g. nuclear power control, medical equipment, ships, vehicles,
railways, aircraft, combustion apparatus, safety equipment, crime/disaster prevention devices, etc.)
Failure to follow this instruction may result in re, personal injury, or economic loss.
2. Install on a device panel to use.
Failure to follow this instruction may result in re.
3. Do not connect, repair, or inspect the unit while connected to a power source.
Failure to follow this instruction may result in re.
4. Check ‘Connections’ before wiring.
Failure to follow this instruction may result in re.
5. Do not disassemble or modify the unit.
Failure to follow this instruction may result in re.
6. Since Lithium battery is embedded in the product, do not disassemble or burn the unit.
Failure to follow this instruction may result in re.
Caution
1.
When connecting the power/sensor input and relay output, use AWG 20
tighten the terminal screw with a tightening torque of 0.74 to 0.90N.m.
Failure to follow this instruction may result in re or malfunction due to contact failure.
2. Use the unit within the rated specications.
Failure to follow this instruction may result in re or product damage.
3. Use dry cloth to clean the unit, and do not use water or organic solvent.
Failure to follow this instruction may result in re.
4. Do not use the unit in the place where ammable/explosive/corrosive gas, humidity,
direct sunlight, radiant heat, vibration, impact, or salinity may be present.
Failure to follow this instruction may result in re or explosion.
5. Keep metal chip, dust, and wire residue from owing into the unit.
Failure to follow this instruction may result in re or product damage.

Caution during Use
1. Follow instructions in ‘Cautions during Use’. Otherwise, It may cause unexpected accidents.
2. In case of contact input, set count speed to low speed mode (1cps, 20cps, 30cps) to operate.
If set to high speed mode (1kcps), counting error occurs due to chattering.
3. Keep away from high voltage lines or power lines to prevent inductive noise.
In case installing power line and input signal line closely, use line lter or varistor at power line and
shielded wire at input signal line.
Do not use near the equipment which generates strong magnetic force or high frequency noise.
