■ Safety Levels and De󶍾nitions
DANGER
:Indicates that failure to comply with the notice may result in severe personal
injury or even death.
WARNING
: Indicates that failure to comply with the notice may result in severe personal
injury or even death.
CAUTION
: Indicates that failure to comply with the notice may result in minor or moderate
personal injury or damage to the equipment.
Keep this user guide properly for reference when necessary and forward this guide to the end
user.
Control System Design
WARNING
◆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.
CAUTION
◆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.

Installation
WARNING
◆The equipment must only be used indoor. Ensure that the environment meets the
requirements in the following "General Speci󶍾cations" section.
◆ Keep the equipment away from strong magnetic 󶍾elds, direct sunlight, high temperature,
󶍿ammable gases, steam, and dust. Failure to comply may result in damage.
◆ Do not use the equipment in places with tremendous temperature 󶍿uctuation or high
humidity. Failure to comply may result in condensation inside the equipment, causing
equipment damage.
◆Ensure that all cables are securely connected to the equipment. Loose connection may cause
I/O signal errors.
CAUTION
◆Install this product within the storage temperature range recommended by this user guide.
Failure to comply may result in a display fault on the PLC.
Wiring
DANGER
◆ Before wiring, cut o󶍽 all power supplies. Failure to comply may result in electric shock or
circuit damage.
◆Wire the DC power supply to the dedicated terminal as described in this guide.
◆Prevent metal chippings and wire ends from dropping into the PLC during screw hole
processing and wiring. Failure to comply may result in 󶍾re, faults, and malfunction.
◆After wiring, check carefully to ensure that the operating voltage and the positions of terminals
are correct. Failure to comply may result in 󶍾re or accidents.
☞Grounding
Independent or single-point grounding is recommended, whereas common grounding is
prohibited.

CAUTION
◆ Cut o󶍽 the main power supply before connecting the power supply of the equipment. Failure
to comply may result in electric shock.
◆The input power of the equipment is DC 24V. Therefore, check regularly that the DC power
provided by the switching-mode power supply unit is stable.
Operation and Maintenance
CAUTION
◆During use, pay attention to PLC protection, perform touch operations by hand, and avoid
touching the display panel by using tools. The user shall be responsible for panel damage
caused by excessive external force.
◆Lithium batteries and capacitors may contain ingredients that are harmful to health and
pollute the environment. Treat scrapped controllers as industrial waste.
◆Lithium batteries needs to be replaced by a professional.
☞Safety Recommendations
◆In positions where the operator directly contacts the machinery part, for example, where a
machinery tool is loaded and unloaded or where a machine runs automatically, the onsite
manual devices and any other alternative means must be carefully arranged and designed so
that they are independent of the PLC and can start or terminate the automatic running of the
system.
◆ If programs need to be modi󶍾ed when the system is running, apply a lock or take any other
necessary measures to ensure that only authorized personnel can perform such modi󶍾cation.
Disposal
CAUTION
◆Treat scrapped controllers as industrial waste. Dispose of the battery according to local laws
and regulations.

CH0-X0 = screenprint X0, label CH1-Y10 = screenprint Y10, and label
COM0 = screenprint C0, with CH0 for channel 0 and CH1 for channel
1.
◆Terminals of CH0 may distinguish between COM0 and SS0, and
those of CH1 between COM1 and SS1. For example, CH0-Y0
corresponds to COM0, and CH0-X0 corresponds to SS0.
◆SS0 is the common terminal for X0–X3 (high-speed inputs) of
channel 0, and SS1 is the common terminal for X4–X17 (medium-
speed inputs and general inputs) of channel 1.
◆C0 is the common terminal for the Y0–Y7 output terminals of
channel 0, and C1 is the common terminal for the Y10–Y15 output
terminals of channel 1.
■Wiring Precautions
1) The maximum length of the expansion cable for a high-speed I/O port must
not exceed 3.0 m.
2) In the routing process, avoid bundling expansion cables with the power cable
(of high voltage and current) and other cables that transmit strong interfering
signals. Route expansion cables separately and avoid parallel routing.

Tube cable preparation procedure:
1) Remove the insulation of the cable so that a length of 11–14 mm of the
conductor is exposed, and put the cable through a cable marking sleeve.
2) Insert the exposed end into the hole of the cable lug, and then crimp it with
the recommended crimping tool.
3) Insert the cable lug into the stud terminal block and fasten it with a
screwdriver, with a tightening torque not more than 5 in-lbs.

FastEthernet has proved that the cable length between devices should not
exceed 100 m in the case of an EtherCAT bus. A longer cable will result in signal
attenuation that a󶍽ects communication.

The following 󶍾gure shows the RS485 bus connection topology. It is
recommended that the RS485 bus be shielded twisted pairs, with the 485+ and
485- terminals connected by the twisted pairs. Connect a 120 Ω termination
resistor to each end of the bus to prevent signal re󶍿ection. Connect the reference
grounds of the RS485 signals of all nodes together. Up to 31 nodes can be
connected. The branch distance of every node must be less than 3 m.
