Product installation specifications
Physical dimension requirements: All installation dimensions are in millimeters, with a tolerance of * * ± 0.5mm * *. The cutting dimensions and panel thickness vary for different models/suffixes (45/50/A6/A7), such as the maximum panel thickness of 8mm for ECT-16 and 9mm for ECT-VGA.
Preparation before installation: Remove the red battery protection strip from the panel, prepare the matching fixed bracket and sealing gasket (rectangular/linear, shipped with model).
Installation of sealing gasket
Rectangular sealing gasket: applied around the cutting edge, without tension, replaced after each disassembly and assembly.
Linear sealing gasket (thin+thick strip): The thin strip fits the cut, and the thick strip is attached to the panel frame, starting from the midpoint/1/3 of the lower side, with no overlap at both ends.
Fixing method: Place the four fixing brackets in the long corners of the panel, tighten the fixing screws until the panel frame contacts the installation surface.
Power supply and grounding (core requirements)
Protective earth (PE) must be connected, which can be grounded through the screw/quick terminal next to the power terminal. Power terminal 3 also needs to be grounded.
The power supply needs to have dual/reinforced insulation, and the power supply circuit can be floating or grounded. The floating circuit is connected to the power supply ground through a 1M Ω resistor and a 10nF capacitor.
Ensure that the power supply meets the power consumption requirements of the panel, and all electronic devices of the control system must be grounded in a standardized manner.
Interface connection and module installation
Port wiring: The layout of ports varies among different models. The location of the core ports (POWER/PLC/PC/AUX) can be found in the corresponding model diagram. The PLC port pins are defined as the core (such as 1-pin chassis ground, 2-pin RXD, 3-pin TXD, 5-pin GND, etc.).
AUX module installation steps
Turn off the panel power; 2) Loosen the two screws on the back cover; 3) Remove the back cover (eTOP/ePAD series pry open from the side slot); 4) Insert the communication module into the red interface and lock it; 5) Reinstall the back cover and tighten the screws; 6) Paste module function labels in the designated area.
No PC/Printer Port model: This type of model uses PLC Port as a PLC/PC composite port, and requires CA2/CA114 cable in conjunction with a gender converter for programming.
Programming cable: The core is CA2/CA114, used for connecting the panel to the computer, with corresponding cross pins (such as panel RXD connected to computer TXD).

Daily maintenance and component operation
(1) Battery replacement
Battery function: Maintain real-time hardware clock, event list, and recipe data. When the battery is low, there are three prompts: FAULT/FLT LED flashes, the system menu displays Battery LOW, and the S6 bit value of RDA changes.
Replacement steps: 1) Power off; 2) Loosen the 4 screws of the battery compartment; 3) Remove the battery compartment; 4) Replace the CR2430 battery; 5) Reinstall the battery compartment and tighten the screws; 6) Power on verification status.
Attention: Battery replacement may result in loss of backup data. It is strictly prohibited to mix battery models. Waste batteries should be disposed of according to regulations to avoid explosion risks.
(2) Other component operations
Dismantling of nameplate: Pinch the exposed part of the nameplate and slide it downwards to remove it. When replacing, use a nameplate of the same thickness and do not thicken it.
Memory card operation: Some models use SSFDC memory cards, and anti-static measures should be taken during operation: clean the gold fingers (soft tissue), avoid finger contact, and place them in an anti-static box after disassembly. Do not wipe with synthetic cloth.
Panel cleaning: Use only a soft cloth and neutral soap to wipe, do not use solvents.
Basic usage and key commands
Operation mode: The core is divided into configuration mode (programming/calibration) and operation mode (normal operation), which can be switched through buttons/touch screen.
Programming requirements
Software: Designer V6 (Windows application, requires separate system installation).
Communication parameters: baud rate 9600 (up to 38400 for PC port models), no parity check, 1 stop bit, software default adaptation.
Connection: Panel cut configuration mode, connect the computer COM1/COM2 port with CA2/CA114 cable.
Button commands: divided into page mode, alarm mode, data entry mode, password mode, etc., with different button functions in different modes; Models without physical buttons (such as ECT-16) use touch screens to implement virtual buttons; Some models do not have CLEAR keys, and functions can be achieved through combination keys. Long pressing the key for 2 seconds can activate special functions (such as ENTER 2s to enter data entry).
Touchscreen model: Comes with default virtual buttons (CLEAR/ENTER), which automatically pop up a numeric keypad when entering data.
Troubleshooting and Calibration
(1) Enter configuration mode
There are button models: Power off → Press and hold any 3 buttons → Power on and hold until the screen displays the configuration mode.
Keyless touchscreen models (ECT-16/ELT-16/RT-16): Power off → Left hand touches the middle left side of the screen → Power on → Right hand touches the middle right side of the screen once per second until configuration mode is displayed.
(2) Touch screen calibration
Standard calibration: Enter configuration mode → touch the CLEAR key on the screen until a small circular mark appears in the upper right corner → long press the mark to the lower left corner → follow the prompts to touch the designated key/ENTER key in sequence until switching back to operation mode.
Emergency calibration: suitable for situations where standard calibration cannot be entered, power off → power on → touch the middle of the screen once per second until entering calibration mode → execute standard calibration steps.
(3) Fault diagnosis of indicator light (core LED)
LED name, color, status, meaning
Fault/FLT red out with no hardware malfunction, battery is normal
Flashing battery low battery
Constant hardware malfunction
RUN green out hardware malfunction
The constantly lit panel is operating normally
COM green flashing communication error (some models)
Always on, communication is normal
ALARM red out with no alarm
Flashing alarm requires confirmation
Constant light alarm activation
Safety and Usage Guidelines
Applicable standards: Following EN 60204-1 (Industrial Control System Safety), EN 61000-6-4 (Emission Interference), EN 61000-6-2 (Anti Interference), the product comes with CE certification.
Operation taboos
It is prohibited to directly control motors, valves, and other actuators without safety protection using panels to avoid danger caused by malfunctions.
It is prohibited to remove the panel back cover when it is powered on. Before operating the live panel, electrostatic discharge treatment must be carried out first.
Do not use tools such as screwdrivers to operate buttons/touch screens to avoid damage.
Environmental taboos: Avoid long-term exposure of panels to direct sunlight (accelerating panel film aging), and prohibit installation in environments that come into contact with corrosive chemicals.
