Installation and wiring specifications

Installation requirements

Embedded panel installation, panel thickness 1.6~10mm

Reserved ventilation spacing of * * ≥ 100mm * * around the perimeter

Tilt installation angle * * ≤ 30 ° * *, cooling is required if it exceeds 30 °

Wiring safety

The power must be disconnected for wiring, and live plugging and unplugging are strictly prohibited

Grounding: Independent grounding priority, grounding resistance * * ≤ 100 Ω * *, wire diameter ≥ 2mm ²

The power circuit needs to be equipped with a circuit breaker, and this machine does not have a power switch

CF card usage

It must be plugged in and unplugged after the power/ACCESS light is turned off

Power off is prohibited during reading and writing, and data is backed up regularly

System settings

Divided into two categories: offline settings and system settings:

Offline settings

Network: Configure IP/Subnet Mask/Gateway

Buzzer: Off/Touch Response/Full Screen Response

Backlight: 4 brightness levels, automatic extinguishing, burn protection

Self check: screen, font, touch, serial port, video memory

System Settings

Date and time, language, version information

Memory usage viewing, system restart

Fault diagnosis

1. No display troubleshooting

Check if the power supply voltage is within the rated range

Confirm LED status: green=normal, orange=backlight damaged

Check if the Pro Designer screen is downloaded correctly

Check if the power terminal wiring is secure

2. Troubleshooting of communication abnormalities

Confirm that the PLC protocol and driver settings are correct

Check the communication line wiring and shielding grounding

Verify that the baud rate, data bits, and parity bits are consistent

Maintenance and upkeep

Daily cleaning

Neutral cleaning agent soft cloth wiping, organic solvents are prohibited

regular replacement

Install gasket: replace annually

Backlight: Replace when the LED is orange, match the model with the model

Lithium battery

Used for clock and data backup, cannot be replaced by oneself, please contact the agent

Key issues

Question 1: Why is it strictly prohibited to use touch screens as emergency stop buttons for GP2000 series HMI? What are the security risks?

Answer: The touch screen belongs to software control and may maintain or fail signals due to communication failures, crashes, black screens, or program errors; And emergency stop involves personal safety, and the hardware emergency stop button must be used to directly cut off the circuit. If a soft button is used, failure to stop the machine in a timely manner may result in personal injury or equipment damage.

Question 2: What is the correct process for inserting and removing CF cards? What are the consequences of violating regulations?

Answer: Correct process: First, turn off the CF card access switch → Confirm that the ACCESS light is off → Open the cover and plug it in → Close the cover after plugging it in → Power on for use. Violation consequences: Inserting or unplugging during read/write operations can result in data damage to the CF card, file loss, burning of the HMI storage chip, and inability to recover data.

Question 3: After the backlight is turned off, the HMI touch screen can still be operated. What are the hidden dangers? How to avoid it?

Answer: Hidden danger: If the operator cannot see the screen but the touch still takes effect, it is easy to accidentally touch the button or operate the equipment, causing safety accidents. Avoidance method: Enable the * * “Do not touch after backlight burn out” * * function in offline settings. When the backlight is damaged, the touch will be automatically locked and forced to repair before operation.
