6. Operation
- Do not change the controller's function switch settings during the
operation; otherwise, it will cause injury.
- Do not approach the machine after instantaneous power failure
has been recovered.
Doing so may result in injury if the machine starts abruptly, it will
cause injury.
- Be sure to check that the power supply specifications are correct;
otherwise, it may caused controller failture.
- Be sure to provide an external emergency stop circuit so that
operation can be stopped with power supply terminated immediately.
- Be sure to conduct independent trial runs for the controller before
mounting the controller to the machine;
otherwise, it may cause injury.
- When an error occur, be sure to eliminate the cause, ensure
safety, and reset the error before restarting operation;
otherwise, it may cause injury.
7. Maintenance And Inspection
- Do not disassemble, remodel, or repair the unit;
otherwise, it will cause electric shock, fire, and unit malfunction.
- The capacitor of the power line deteriorates through prolonged use.
We recommended that the capacitor be replaced every five years
to prevent secondary damage.
8. Disposal
- Be sure to handle the controller as industrial waste while
disposing of it.
1. Handling Precautions
- Do not touch components inside of the controller;
otherwise, it will cause electric shock.
- Do not damage the cable by applying excessive load, placing
heavy objects on it, or clamping;
otherwise, it will cause electric shock or fire.
DANGER
- Turn the power supply OFF before wiring, transporting, and inspecting
the controller; otherwise, it may cause electric shock.
- Provide an external safety circuit so that the entire system
functions safely even when the controller is faulty.
- Connect the grounding terminal of the controller;
otherwise, it may case electric shock or malfunction.
- Do not use the controller in the following palces; water splashes,
the atmosphere of the corrosion, the atmosphere of the flammable
vapor, and the side of the combustibility.
Doing so may result in fire or the controller may become faulty.
- Be sure to use the controller and the ABSOCODER sensor in the
environment designated by the general specifications in the manual.
Failure to do so may result in electric shock, fire, malfunction or unit
failure.
- Be sure to use the specified combination of the ABSOCODER
sensor, controller and sensor cable; otherwise, it may cause fire or
controller malfunction.
CAUTION
2. Storage
CAUTION
- Do not store the controller in a place exposed to water, or toxic
gas and liquid.
- Be sure to store the controller in designed temperature and humidity
range, and do not exposed to direct sunlight.
- Be sure to consult with NSD when the controller is stored for long
periods.
- Do not hold the cable or shaft of ABSOCODER sensor during
transport; otherwise, it will cause injury or controller malfunction.

4. Installation
- Do not step on the controller or place heavy objects on the controller;
otherwise, it will cause injury.
- Do not block the exhaust port or allow any foreign matter to enter
the controller; otherwise, it will cause fire or unit failure.
- Be sure to secure the controller and ABSOCODER sensor with the
provided brackets; otherwise, it may cause malfunction, injury, or
drop.
- Be sure to secure the specified distance between the main body
and the control panel or other equipments; otherwise, it may cause
malfunction.
5. Wiring
- Be sure to secure the terminal block firmly; otherwise, it may have
risk of fire.
- Be sure to mount the terminal cover provided with the controller,
before supplying the power, starting operation after the installation,
and wiring; otherwise, it may cause electric shock.
- Be sure to keep the sensor cable, control cable, and communication
cable at least 300 mm away from the main circuit and power line;
otherwise it may cause injury or malfunction.
- Be sure to connect all cables correctly; otherwise, it may cause injury
or controller malfunction.
- Be sure to firmly connect the external I/O connectors and sensor
connectors; otherwise, it may cause incorrect inputs and outputs or
injury.
