Installation and Startup Guide

This document covers the installation of cMT3071/3072 Series HMI, for the detailed
specifications and operation, please refer to Datasheet, Brochure and EasyBuilder Pro User
Manual. Please read all warnings, precautions, and instructions on the device carefully before
use.

Install Environment:

Installation Instructions

Use a control box that provides enough stiffness.
Cutout Dimension: 192 mm x 138 mm. Secure the
operator panel in position, using all the fastening
holes and the provided brackets and screws. Screw
Torque: 2.6 ~ 3.9 lbf.in. (For reaching waterproof
effect and preventing the panel from being deformed.)
Plan for adequate space around the unit and inside
the enclosure, for ventilation and cables. Consider the

heat from other devices inside the enclosure. The
ambient temperature around the unit must be 0 ~
50°C
Minimum required clearances (along the overlay): Top / Bottom / Sides 15 mm
Maximum panel thickness: 4.5 mm
The aluminum flat-sheet at the back of the unit is a heat sink. Please be careful not to touch the heat
sink since its heat can rise to 70°C in maximum when the unit is running. Planning for a 3cm space
between the back of the unit and other devices is recommended.

Power Connections

Power Connector Specifications:
Wire AWG: 28~12
Operating Temperature: -40°C ~105°C
Screw Torque: 3.47 lbf-in (max.)

NOTE:

1. Connect positive DC line to the ‘+’ terminal and the
DC ground to the ‘-’ terminal.

2. When downloading project using a USB cable, do
not connect HMI with PLC and PC simultaneously, for
electric potential difference may result in damage to
HMI or PC.

Unpacking the Unit

Unpack and check the delivery. If damage is found, please contact the supplier.

NOTE: Place the operator panel on a stable surface during installation. Dropping it or letting it

fall may cause damage.

The package includes:
(1) Installation Instruction, 2-sided A4 *1 (2) Human Machine Interface *1 (3) Power Connector *1
(4) Brackets & Screws *1 pack (5) Fuse 3.15A/250V 5*20mm *1 (6) USB Stick Clamp & Tying Strap *1

USB Stick Clamp Usage

Combining the USB Stick with the clamp and the tying strap can prevent USB stick from disconnecting
with HMI when strong vibration is present.

1. Insert the USB connector to the clamp and tie them together with the tying strap.

2. Press the spring and insert the USB stick into HMI.

System Settings

When HMI is powered up and displays image, press
the round Start Button in the upper-left corner of the
screen to open the Setting dialog box. Tap the lock
icon and log in. (Default System Password:

111111)
Go to the Network tab, and setup your network.
In Setting dialog box you can see device information,
configure general settings, set HMI
Time/Date/Name, and more.

EasyBuilder Pro Software Settings

Launch EasyBuilder Pro software, select your project file, press F7 shortcut key to open the download
dialog box: Select Ethernet > IP tab > Enter your HMI IP > Click Download to download this project
file to HMI.
Using screensaver and backlight saver is recommended in order to avoid image persistence caused
by displaying the same image on HMI for a long time.
(Please refer to EasyBuilder Pro User Manual for software operation details.)

Communication Connections

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

Use power output that meets SELV (Safety Extra-Low Voltage) requirements. 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 3.15A.

Fusing Require­ments

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 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
checks built into the program, with an out-of-limit safe shut down procedure to ensure safety of
personnel.

Touchscreen Calibration & Restore Factory Default

Restore Factory Default:
Apart from flipping DIP SW 1 to ON position, restoring factory default can be carried out by following
Step 5 to open the Setting dialog box. Go to Reset Options tab and press the button of “Reset HMI to
default”. 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 for more
than 2 seconds when HMI starts.

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.
Replacing fuse shall be performed by qualified personnel only.

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.
