UniOP Operation Panel Installation and Maintenance Guide

3.3 Installation steps

Drilling: Drill holes on the cabinet according to the drawing size to ensure smooth edges.

Install sealing strip: Provide rectangular or two linear sealing strips according to the model. The rectangular sealing strip should be laid around the opening to avoid stretching; The fine strip in the linear sealing strip is laid around the opening, and the thick strip is laid behind the panel frame, with no overlap at both ends.

Fixed panel: Insert the four mounting brackets into the slots on the side of the panel (located near the corners of the long side), tighten the fixing screws until the frame contacts the cabinet panel.

Check protection: Ensure that the sealing strip is compressed evenly, the front panel is tightly attached to the cabinet, and meets IP65 protection.

3.4 Cleaning and Maintenance

Clean the front panel with a soft cloth dipped in neutral soapy water, and do not use solvents.

If using an SSFDC memory card, keep your golden fingers clean to avoid oil contamination; When cleaning, use a soft dry cloth and avoid synthetic fiber cloth to prevent static damage. Store in an anti-static protective box when not in use.

Electrical connection

4.1 Power Supply and Grounding

Power terminal block: The panel comes with a pluggable terminal, labeled as "POWER".

Power requirement: 24 VDC, with a capacity that meets the maximum power consumption of the panel (see technical data sheet).

Grounding:

Terminal 3 (GND) must be connected to the ground.

The back of the panel is equipped with grounding screws or Faston terminals (marked with yellow labels), which also need to be connected to the ground.

All electronic devices of the control system should be well grounded to suppress electromagnetic interference.

The power circuit can adopt floating or grounding methods. If floating ground is used, the power common terminal inside the panel has been connected to the ground through a 1 M Ω resistor and a 4.7 nF capacitor in parallel.

4.2 PLC ports

Interface type: D-sub 15 pin male head.

Signal standards: RS-232, RS-422, RS-485, or 20 mA current loop (selected via cable).

Pin definition:

1: Rack floor

2：RXD

3：TXD

4: +5V output (maximum 100mA)

5：GND

6：CHA-

7：CHB-

8：TX+20 mA

9：TX-20 mA

10：RTS

11：CTS

12：RX+20 mA

13：RX-20 mA

14：CHA+

15：CHB+

Attention: Special cables that match the PLC type must be used, otherwise communication will not be possible.

4.3 PC/Printer Port

Interface type: D-sub 15 pin female head, only supports RS-232.

Functional Mode:

Configuration mode: Connect to PC for programming (using CA2 or CA114 cable).

Run mode (UniNET server): Connect to the UniNET network.

Run mode (non UniNET or client): Connect to a serial printer.

Pin definition:

1: Rack floor

2：RXD

3：TXD

4: +5V output (maximum 100mA)

5：GND

6-9: Reserved

10：RTS

11：CTS

12-15: Reserved

Programming cable CA2 wiring (D-sub 9-pin PC end to 15 pin panel end):

PC end (9 pins) → panel end (15 pins):

2 (RXD) → 3 (TXD)

3 (TXD) → 2 (RXD)

5 (GND) → 5 (GND)

1 (DCD) → 10 (RTS)

4 (DTR) → 11 (CTS)

The shell is shielded.

4.4 AUX port

Interface type: D-sub 9-pin female head.

Function: Industrial network connection can be achieved through optional communication modules such as Profibus, DeviceNet, etc.

Module installation:

Turn off the power.

Loosen the two screws (marked A) on the back cover and remove the back cover.

Insert the module into the red connector and ensure it is securely locked.

Reinstall the back cover and secure the screws.

Attach the AUX function label (Area B) that comes with the module.

4.5 Ethernet ports

Interface type: RJ45.

Pin definition:

1：TX OUT +

2：TX OUT -

3：RX OUT +

6：RX OUT -

The remaining pins are unused.

LED status:

ON: No valid link detected.

OFF: A valid link has been detected.

Function: Used for communication with the upper computer, program download, data acquisition, and UniNET network.

4.6 External keyboard port

Some models (such as BKDR-16, MKDH series, etc.) provide external keyboard interfaces that can be connected to ET-F or AT-F keyboards, with cables provided with the keyboard.

Battery replacement and LED indicator light

5.1 Battery Maintenance

Maintain data: Real time clock, event list, recipe data, etc. are maintained by lithium batteries.

Battery low voltage indication:

The FAILT/FLT indicator light is flashing (red).

The system menu displays' Battery LOW '.

The S6 bit in RDA indicates.

Replacement steps:

Turn off the power.

Loosen the four screws on the two metal plates that secure the battery box with a screwdriver and remove the battery box.

Remove the old battery (CR2430) and replace it with a new battery (pay attention to polarity).

Replace the battery box and tighten the screws.

Power on and check if the battery status has returned to normal.

Warning: Replacing the battery may result in data loss and requires early backup. The battery model must be consistent with the recommendation, and discarded batteries should be disposed of according to local regulations.
