5. 5 Maintenance
(1) Before performing installation, wiring and maintenance, check for accumulated voltage using
a tester at least 5 minutes after the power supply has been switched off.
Accumulated voltage can result in electric shock, fire, and injury.
(1) Perform regular maintenance and inspections.
Confirm that there is no twisting of wires, play in the table or large sliding friction. This may result in
malfunction.
(2) Conduct an appropriate functional inspection and test after completed maintenance.
Stop operation if a device or equipment does not work correctly. Safety cannot be assured in the
event of unexpected malfunction. Conduct a test of the emergency stop to confirm the safety of the
equipment.
(3) Do not disassemble, modify or repair the product.
(4) Removal of equipment.
When the equipment is serviced, first confirm that measures are in place to prevent dropping of
driven objects and loss of equipment, etc., and then cut the power supply from the system. Confirm
safety before restarting the equipment.
(5) Maintenance space.
Allow sufficient space for maintenance and inspection.
6. Controller and Peripheral Devices / Specific Product Precautions
6. 1 Design / Selection
(1) Use the specified voltage.
If the applied voltage is higher than the specified voltage, malfunction and damage to the controller may
result. If the applied voltage is lower than the specified voltage, there is a possibility that the load cannot
be moved due to internal voltage drop. Check the operating voltage prior to start. Check also that the
operating voltage does not drop below the specified voltage during operation.
If the current is too low, the Card Motor may not be able to generate the maximum force or cause a
malfunction.
(2) Do not use the products outside the specifications.
Fire, malfunction, or damage to the product can result. Please check the specifications before using it.
(3) Install an emergency stop circuit.
Install an emergency stop outside the enclosure in easy reach to the operator so that the operator can
stop the system operation immediately and intercept the power supply.
(4) To prevent danger and damage due to a breakdown or malfunction of this product, which may
occure at a certain probability, a backup system should be arranged in advance by using a
multiple-layered structure or by making a fail-safe equipment design, etc.
