Jumper Settings
Please prepare a jumper cap for setting the jumpers.
Another way to enter touch screen calibration mode is: Press and hold anywhere on the screen for more
than 2 seconds when HMI starts.
Battery Replacement
Battery replacement shall be performed by qualified personnel only and care must be taken when handling
lithium batteries. For more information on battery replacement and disposal considerations, please refer to

NOTE:
Make sure that all local and national electrical standards are met when
installing the unit. Contact your local authorities to determine which codes apply.
Power
The unit can be powered by DC power only, voltage range: 10.5~28VDC, compatible with most
controller DC 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.
Fusing
Require-
ments
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.
High Voltage
An Internal fuse will prevent damage for overcurrent
condition however it isn’t guaranteed. DC
voltage sources should provide proper isolation from main AC power and similar hazards.
Emergency Stop
A Hard-wired EMERGENCY STOP should be fitted in any system using an HMI to comply with
ICS Safety Recommendations.
Supply Voltage
Condition
Do not power the unit and inductive DC loads, or input circuitry to the controller, with the same
power supply. Note: The 12 or 24 VDC output from some controllers may not have enough
current to power the unit.
Wire Routing
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
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
Hardware
Considerations
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.
If you use any programmable control systems that require an operator, be aware that this
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.
Programming
Considerations
To conform with 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
checks built into the program, with an out-of-limit safe shut down procedure to ensure safety of
personnel.
