Micro Innovation GF1 series industrial touch screen (Micro Panel)

Micro Innovation GF1 series industrial touch screen (Micro Panel)

Product Introduction

GF1 Micro Panel is a visual operation unit designed for medium to high complexity automation systems.

Engineering image project data is stored on PC-MCIA (PC card) memory cards; It can be downloaded through PC card writing or via RS232 system port; The configuration software is GALILEO, and the runtime system is GRS.

The backplane has two expansion slots, Slot0 and Slot1, which can be used to insert communication modules and achieve docking with PLC/fieldbus; Support running two different communications simultaneously.

This document takes the 10.4-inch model (GF1-10xxx) as the main example, and the definitions of terminals and indicator lights for the entire series remain consistent.

Installation requirements

4.1 Installation method

Two installation forms:

Front panel installation: 4 countersunk screws for front installation, to be used when the rear of the cabinet cannot be reached for operation.

Backboard bolt installation: requires space behind the cabinet, and is locked from the back with washers and nuts.

Combined with the sealing gasket, it can achieve the front panel IP65 protection level; IP65 matching compression frame needs to be ordered separately (10 inch order number 65 20 963100).

Environment and heat dissipation

Working environment temperature: 0~+50 ℃; The highest altitude is 2000m, installed vertically, with smooth air convection.

The heat dissipation and ventilation ducts must not be obstructed; Leave at least 3cm ventilation gap around the shell; The minimum distance between the entire machine and other components inside the cabinet is 10cm.

Do not expose the screen to direct sunlight, as UV rays and high temperatures can damage the LCD.

After installation, the storage card, download button, wiring terminals, and indicator lights must reserve operable space.

10 inch external dimensions

Overall appearance: 342 × 270 × 85 mm; weight approximately 4.8 kg

Cabinet opening size: 316   mm × 244   mm

Wiring interface

5.1 AC Power Supply Version GF1-xxxxA

Power supply: 100-240VAC, maximum power consumption of 40W; built-in 4.0AT replaceable fuse; Pin type socket, pin L live wire, N neutral wire, PE protective ground.

⚠️ The PE protective ground must be reliably grounded to prevent electric shock hazards.

5.2 DC Power Supply Version GF1-xxxxD

Power supply 24VDC, working range 20.4-28.8V, maximum surge 3A/2s, maximum power consumption 40W, typical current 1A; built-in 4.0AT replaceable fuse; Terminal definition:+24V, PE, 0V.

5.3 System Port (9-pin D-Sub-Male RS232)

Function: Serial port download project, connect to upper PC; non isolated interface.

Pin: 2-RxD, 3-TxD, 5-GND; Pin 9 can output+5V through motherboard jumper JP8 for external accessory hardware; This 5V output has no short-circuit protection and is only used as an original accessory.

PC MCIA Memory Card Slot (Slot0)

Project engineering storage media, supporting JEIDA PCMCIA Type-I/Type-II; Supports Flash linear cards (up to 64MB); Firmware ≥ 1.10 supports ATA Flash.

Random card compression must be used to secure the PC card; In a vertical installation state, the storage card without compression will loosen and fall off.

Infrared Touch Screen

7.1 Working principle

Infrared matrix touch: Infrared emission/reception channels are distributed around the screen, with a total of 70 IR channels; Touch to block the light path for detection.

Large area pressing ≥ 20mm × 20mm does not recognize; Severe dirt/component damage causing continuous obstruction will result in the channel being blocked by the controller and no longer participating in detection.

7.2 Power on self-test

Automatic self check of all IR channels every time the device is turned on; If the channel signal is too low, the screen will report a fault, and the DEF/DIRTY indicator light will light up, usually due to dirty borders; The screen can still function.

Do not touch the screen during the startup process, as it may interfere with the self-test.

7.3 Maintenance and Cleaning

Clean the front frame of the equipment (PMMA acrylic) with a soft damp cloth; It is strictly prohibited to use solvents to wipe the front frame, as it may corrode the plastic; Scratching of hard materials is prohibited.

Status LED indicator light (below Slot1)

Supply OK: The power supply is normal (+5V,+12V power supply), the light is off, check the fuse. Power on all touch LED lights and perform a brief self check for 0.3 seconds.

Initialization/COM: Touch controller initialization completed; When touching the screen, it briefly turns off for about 0.3 seconds.

COM ERROR: Communication failure between touch controller and motherboard; Constant illumination indicates hardware malfunction.

DEF/DIRTY: IR channel signal attenuation; Most of them are dirty front frames that need to be cleaned.

System Expansion Slot Slot0/Slot1

Two slots are used for communication modules, which can simultaneously insert two communication boards to achieve dual bus operation.

Pay attention to ESD electrostatic protection when disassembling and assembling modules; Power off plugging and unplugging; The module must be screwed tightly; Only Micro Innovation original modules can be used.

Key points of installation wiring and EMC electromagnetic compatibility

All data communication cables (RS232, expansion module) must use shielded cables; The power cord does not need to be shielded.

Shielding layer: Copper braided shielding mesh; The connector must have a metal casing; The shielding layer is connected to the D-Sub metal casing with low impedance.

Shielding treatment process: Peel off the cable, fold the shielding braided mesh backwards and cover it on the outside of the sheath, and protect it with a heat shrink tube; Only retain the 5-8mm braided mesh contact connector metal clamp.

If the HMI and PLC are placed in different cabinets and the shielding layer is grounded at both ends, equipotential connection wires need to be added to prevent the shielding layer from burning out the joints due to large 50Hz circulating currents.

Important safety warning

This device cannot be used for safety related protection functions, as malfunctions may pose a risk to personal safety and equipment.

Pay attention to ESD static electricity and power-off operation when disassembling and assembling communication modules.

The PE protective ground of AC models must be connected to the protective ground.

The storage card must be fixed with a pressure plate to prevent it from falling off.

The ventilation duct cannot be blocked; Avoid direct sunlight on the screen.

Cleaning the frame with solvents is prohibited to prevent plastic damage.
