UniOP ePALM10 Handheld Human Computer Interface

4.2 Keyboard and Indicator Lights

The standard keyboard layout is shown in Figure 2, including directional keys, numeric keys, function keys, etc. Users can customize keyboard lamination according to their needs (consult the manufacturer).

The meaning of the front panel LED indicator light is as follows:

Meaning of LED color status

Fault (red), red off, no hardware malfunction

Low voltage of flash battery

Illuminate hardware malfunction

Button feedback (green), green off, no button pressed

Press the illuminated button (visual feedback)

Running (green) green extinguishing hardware failure

The bright device is running

Communication (green) flashing green communication error

Bright communication is normal

Alarm (red), red off, no alarm

Flashing alarm needs to be confirmed

Illuminate alarm activation

User LED (green) Green User control can be controlled through macro editor, such as indicating recipe/event backup

The RDA mapping between LED and buttons can be found in the manual table for easy access in the program.

4.3 Battery replacement

The battery is used to maintain real-time clock, event list, and recipe data. When the battery is low voltage, the fault LED flashes or the system menu prompts. Replacement steps:

Turn off the device power.

Loosen the 6 screws of the housing with a screwdriver and open the handheld device.

Find the battery (CR2430) on the CPU motherboard and remove the old battery.

Replace with a new battery (pay attention to polarity).

Close the casing and tighten the 6 screws.

Power on and check the battery status.

Attention: Replacing the battery may result in the loss of retained data, which needs to be backed up in advance.

4.4 Power Supply and Grounding

The equipment must be grounded (PE) to suppress electromagnetic interference. The power circuit can be floating or grounded, and the internal power supply common terminal is grounded through a 1M Ω resistor in parallel with a 3.3nF capacitor. The power supply needs to meet dual or reinforced insulation requirements. Wiring diagram 4: Connect the+24VDC to the red wire, connect the common terminal to the black wire, and connect the PE to the yellow green wire.

4.5 Applicable Regulations and Safety

EPALM10 complies with EN 60204-1 safety related provisions, including emergency stop, maintain operation control, dual hand control, etc. It is strictly prohibited to use it to directly control motors or valves that are not equipped with safety protection. During maintenance, static electricity must be released and opening the back cover with electricity is prohibited.

4.6 Installation Environment

Avoid prolonged direct sunlight to prevent aging of the panel film.

Avoid contact with corrosive chemicals.

When cleaning, only use a soft cloth and neutral soap, and do not use solvents.

4.7 Startup and Programming

Use Designer 6 software for programming. Connection method:

Serial communication: Connected through PC serial port, parameters 9600/38400 baud, no verification, 1 stop bit.

Ethernet communication: Network parameters need to be configured correctly.

If you are unable to enter configuration mode, you can try forcibly starting by shutting down, holding down any three keys, and turning on until "Configuration Mode" is displayed.

Detailed explanation of connection methods

Different models of ePALM10 have different connection interfaces and cables. The following types are explained.

5.1 Serial Communication Models (-0061, -0062, -3P61, -3P62)

These models include a complete UniOP interface: PC/Printer port, PLC port, AUX port, power supply, emergency stop button (two NC contacts), and enable switch (two 2-position or one 3-position). All signals are led out through a multi-core cable, and the cable ends are spread out, making it easy to directly connect to the control cabinet terminal block. The cable has ferrite magnetic rings inside and cannot be removed.

There are five terminal blocks (CN1~CN5) on the internal interface board, and the signal distribution is as follows:

CN1 (AUX port): corresponds to the 10 pins (1-10) of the AUX port, which can be connected to optional fieldbus modules.

CN2 (PC/Printer port): corresponds to the 10 pins of the PC port, which can be used for programming or connecting to a printer.

CN3 (PLC port): Includes signals such as CHA ±, CHB ±,+5V, GND, RXD, CTS, TXD, RTS, etc.

CN4 (power supply):+24VDC, Common, PE.

CN5 (additional signal): Enable the NO contact of switch A/B.

The cable color coding is detailed in the manual table for easy on-site wiring. When programming, it is necessary to connect the power supply and PC port (as shown in Figure 7).

5.1.1 Optional fieldbus module

The serial version supports some TCM modules (TCM01, TCM02, TCM03, TCM09), which can be inserted into internal expansion slots of the device to achieve bus connections such as Profibus, DeviceNet, CANopen, etc. The installation module requires opening the device and carefully sealing it after insertion. Attention: Bus topology usually does not allow long branch lines, and there are no terminal resistors inside the device. If it is used as the end of the network, external terminal resistors need to be added.
