NOTE:
1. COM2 and COM3 [RS485] 2W support MPI 187.5K, please use one at a time.
2. Only Tx & Rx (no RTS/CTS) may be used for COM1 RS232 when COM3 RS-232 is also used.

Restore Factory Default:
Follow Step 5 to open the Setting dialog box. After login, press the button of "Reset HMI to default".
Another way to restore factory default is entering "default111111" when logging in. An Attention window
shows, enter "yes'.
Please note that the projects and data stored in the unit are all cleared after pressing this button.
Another way to enter touch screen calibration mode: Press and hold anywhere on the screen until HMI
starts.

installing the unit. Contact your local authorities to determine which codes apply.
Use power output that meets SELV (Safety Extra-Low Voltage) requirements. The unit can be
powered by DC power only, voltage range: 24±20%, compatible with most controller DC
Power
systems. The power conditioning circuitry inside the unit is accomplished by a switching power
supply. The peak starting current can be as high as 2A.
Fuse min. rating: 3.15A/250V. Use the fuse only in DC circuit. If the display does not come on
within 5 seconds of power up, remove power. An internal fuse will prevent damage if the polarity

of the DC power is incorrect. Check wiring for proper connections and try to power up again.
Bus
ments
Replacing fuse shall be performed by qualified personnel only.
An Internal fuse will prevent damage for overcurrent condition however it isn't guaranteed. DC
High Voltage
voltage sources should provide proper isolation from main AC power and similar hazards.
A Hard-wired EMERGENCY STOP should be fitted in any system using an HMI to comply with
Emergency Stop
ICS Safety Recommendations.
CAN_L
Do not power the unit and inductive DC loads, or input circuitry to the controller, with the same

power supply. Note: The 24 VDC output from some controllers may not have enough current to

power the unit.
a. Power wire length should be minimized (Max: 500m shielded, 300m unshielded).
b. Please use twisted pair cables for power wire and signal wire and conform to the
impedance matching.
c. If wiring is to be exposed to lightning or surges, use appropriate surge suppression
Wire Routing
devices.
d. Keep AC, high energy, and rapidly switching DC power wiring separated from signal wires.
e. Add a resistor and capacitor in the parallel connection between the ungrounded DC power
supply and the frame ground. This provides a path for static and high frequency
dissipation. Typical values to use are 1M Ohm and 4700pF.
DANGER
The system designer should be aware that devices in Controller systems could fail and
thereby create an unsafe condition. Furthermore, electrical interference in an operator
interface can lead to equipment start-up, which could result in property damage and/or
physical injury to the operator.
Hardware
If you use any programmable control systems that require an operator, be aware that this
Considerations
potential safety hazard exists and take appropriate precautions. Although the specific design
steps depend on your particular application, the following precautions generally apply to
installation of solid-state programmable control devices, and conform to the guidelines for
installation of Controllers recommended in NEMA ICS 3-304 Control Standards.
To conform to ICS Safety Recommendations, checks should be placed in the controller to
ensure that all writable registers that control critical parts of plant or machinery have limit
