Pro face GP2000 Maintenance Guide

#18 (CSB)  ↔ # 19 (ERB) and # 21 (CSA) ↔ # 22 (ERA)

And install a 100 Ω terminal resistor between # 9 (TRMX) and # 10 (RDA) (only when using RS-422).

COM2: 9-pin male seat, only supports RS-232C. Please note that its fixing screws are imperial # 4-40UNC, which is different from the metric M2.6 of COM1.

Important warning: The serial port is not isolated, and the SG (signal ground) must be connected correctly, otherwise it may damage the RS-422 driver circuit. In addition, PIN14 (VCC) outputs DC5V/0.25A without protection, overloading is strictly prohibited.

5. Ethernet and tool connectors

The Ethernet interface is 10BASE-T and uses shielded RJ45 cables. If you directly connect to a PC and the network card does not support cross line adaptation, you need to go through a hub.

Tool Connector is used to download screen programs, cable model GPW-CB02. Power off and plugging are also required.

First startup and offline settings

After turning on the power, GP will load the Pro Designer Runtime. If the screen has not been downloaded yet or system parameters need to be modified, you can touch the top left corner of the screen within 10 seconds after startup, or touch the top right corner+bottom right corner+bottom left corner at the same time to enter the "Settings Menu".

This menu is divided into two tabs: Offline and System.

Offline settings:

Network: Set IP address, subnet mask, and default gateway. After modification, it must be restarted to take effect.

Buzzer: Touch buzzer mode. Optional "None" (off) or "Press Touch Object" (beeps when touched). Note that 'Press Anyway On Panel' is not applicable to the GP2000 series.

Backlight：

Brightness: 4-level brightness adjustment.

Wait: Set the backlight to automatically turn off after idle timeout (extending the lifespan of the lamp), default to OFF.

Enable Touch if Backlight is OFF: Allow touch operation when backlight burn is detected. Strongly recommend setting it to OFF to avoid accidental triggering.

Self Test: Enter the self diagnostic menu (see Chapter 5 for details).

System (system settings):

Date/Time: Use the pop-up numeric keypad to modify the date and time. The internal clock error is about+65 seconds/month at room temperature, and may drift to -380 to+90 seconds/month after long-term use, requiring regular calibration.

Language: Set the system menu language and user application language separately (supporting Chinese, Japanese, Korean, English, etc.).

Memory: Display the usage of application memory (8MB FLASH EPROM) and data backup memory (512KB SRAM).

Ver. Info: View Runtime version and project version number.

Restart: Soft restart GP.

The use of CF cards and data protection

The GP-2500/2600 series supports CF cards (16MB for GP077-CF20 and 32MB for GP077-CF30) for storing screen data, logs, or recipes. Pro Designer does not support extension unit interfaces and only supports CF cards.

Hardware dip switch (located at the bottom, under the cover):

Switch function ON (valid) OFF (invalid)

1 CF card startup control can be started from CF card but not from CF card

2-3 reservations must be kept OFF -

4. Forced closure of CF card cover detection. Forced closure (emergency use). Normal detection

The iron rule for correctly plugging and unplugging CF cards:

Before inserting, open the CF card cover and confirm the direction of the card (with the contacts facing downwards). Gently push in until the eject button pops out.

After closing the lid, the CF card access LED must light up, otherwise it cannot be read or written (closing the lid is a safety interlock).

It is absolutely forbidden to turn off the power, reset or unplug/insert the card when the LED is on, otherwise the data will be damaged or even the card will be scrapped.

Before unplugging, stop accessing the CF card through the screen program, confirm that the LED is off, and press the eject button to remove the card.

The erase life of a CF card is about 100000 times (assuming 500KB of data is overwritten each time), and important data must be backed up to a PC regularly.

Reading CF card on PC: Insert the CF card adapter (GP077-CFAD10) into the PC card slot or use a USB card reader. After testing, the CardDock CF/P (parallel port) of I-O DATA is compatible, but not all card readers are guaranteed to correctly read GP format data.

Troubleshooting and Self Diagnosis

1. The screen does not display at all (black screen)

Check in the following order:

Step check item handling method

Has Pro Designer been used to download the screen? If not downloaded, there may be no display on the first power up. Download any valid image.

Is the "Initial Screen ID" correct in Pro Designer 2? Set to the correct value and download again.

What color is the 3-state LED? Orange → Backlight burned out, replace backlight.

Is the input voltage within specifications? Measure the terminal voltage with a multimeter (for DC24V models, it should be between 19.2-28.8V; for AC100V models, it should be between 85-132V).

Is the wiring of the 5 power terminals correct and securely fastened? Check if L/+, N/-, FG correspond.

Is the power light on? If it doesn't light up, it may be a hardware power board malfunction.
