Control System Design
◆ External circuits must include an emergency stop circuit, a protective circuit, a forward/reverse
operation interlocked circuit, and an upper position limit and lower position limit interlocked
circuit (or reciprocating motion limit interlocked circuit) to prevent damage to the equipment.
◆ Provide a fault protection circuit outside the equipment to prevent unsafe accidental
mechanical movement (for example, unexpected movement in the input/output control area
that cannot be monitored by the equipment).
◆ A user program is required to protect the system when a display, control, communication, or
power failure occurs on the equipment.
◆ When designing the system, ensure that a communication fault between the equipment and
its main controller will not lead to equipment malfunction, which could result in personal
injury or equipment damage.
◆ During operation, keep live objects away from the metal housing of the equipment.
◆ Do not set any switch on the touch screen that may result in personal injury or equipment
damage. A separate switch is required for important operations to avoid accidents caused by
abnormal output or faults.
◆ Do not set any touch switch on the equipment to control safe operations, such as an
emergency stop. Use a dedicated physical switch instead. Failure to comply may result in
severe personal injury or equipment damage.
◆ Do not use the equipment as an alarm device for serious accidents such as serious personal
injury, equipment damage, or system shutdown. Use dedicated hardware and/or mechanical
interlocks for designing important alarms and related control and trigger devices.
