(8) Do not supply 24VDC power supply constantly to the [LK RLS].
Only supply 24VDC power supply to the [LK RLS (Lock release)] terminal during normal operation. If
power is supplied to the [LK RLS] terminal continuously, the lock will be released, and workpieces
may be dropped at stop (EMG).
For details of wiring please refer to the operation manual for the controller (JXC series).
18. Controller and Peripheral Devices/Specific Product Precautions
18.1 Design and selection
Warning
(1) Use the specified voltage.
Otherwise, malfunction and damage to the controller may result.
If the applied voltage is lower than the specified voltage, it is possible that the load cannot be moved
due to an internal voltage drop. Check the operating voltage before use.
(2) Do not operate beyond the specifications.
Fire, malfunction or actuator damage can result. Check the specifications before use.
(3) Install an emergency stop circuit.
Install an emergency stop outside of the enclosure so that it can stop the system operation
immediately and intercept the power supply.
(4) In order to prevent danger and damage due to the breakdown and the malfunction of this
product, which may occur at a certain probability, a backup system should be established in
advance by giving a multiple-layered structure or a fail-safe design to the equipment, etc.
(5) If fire or personal injury is expected due to abnormal heat generation, ignition, smoking of the
product, etc., cut OFF the power supply for this product and the system immediately.
(6) The upper limit of writing cycle to EEPROM of the JXCEH controller is 100,000 cycles.
If the upper limit of writing cycle is exceeded, the writing will not be performed correctly.
