Beckhoff CP69xx long-distance transmission and installation

Operation steps:

Insertion: Insert the control panel into the cut cabinet door opening from the front and ensure that the equipment does not fall off before fastening.

Unfold: Flip the clamping levers on both sides outward by 90 ° to the unfolded state (as shown in sections A and B of the figure).

Locking: Use a 3.0mm hex wrench to tighten the screw on the clamping lever (as shown in section C of the figure) until the panel is firmly attached to the cabinet door.

Attention: After installation, it is necessary to check the sealing between the control panel and the installation wall to ensure the effectiveness of the IP65 protection level.

Chapter 3: Electrical Connection and Grounding Standards

3.1 Definition of Power Interface and Voltage Drop Management

CP69xx introduces a 24 VDC main power supply through a 5-pin voltage socket (X106), and its core power supply pin is defined as:

Pin 4:24V negative pole (-)

Pin 5:24V positive pole (+)

Pin 3: Protective Grounding (PE, used for protective grounding)

Pin 1, Pin 2: Not used (NC)

Power requirements: Rated input voltage of 24 VDC, allowable fluctuation range of 22-30 VDC. The power supply must be NEC Class 2 isolated power supply and equipped with a maximum 4A fuse according to UL 248 standard.

To ensure the stability of long-distance power supply, cables with a cross-sectional area of 1.5 mm ² should be used for longer power lines to reduce voltage drop. The voltage at the device power plug should be maintained at least 22V to withstand unexpected restarts or undervoltage shutdowns caused by grid fluctuations.

3.2 Assembly of power plug and stress relief housing

The power plug (C9900-P927) of CP69xx adopts a unique structure of 5-pin connecting strip and stress relief shell (with zip ties). Engineers need to assemble themselves according to the following steps:

Plug installation:

Peel off the outer layer of the cable by a few centimeters and remove the insulation layer (8-9mm) at the end of the wire core.

Crimp connection terminals (Ferrules) at the end of the online core.

Insert the wire core into the 5-pin connector strip according to the pin definition and tighten the screw.

Stress relief shell installation (see manual figure 13):

Thread the zip tie into the lower half of the stress relief shell.

Insert the assembled connecting strip into the lower half.

Tighten the zip ties and cut off excess plastic sheets.

Close the upper part to the lower part and hear a "click" sound to complete.

Disassembly method: Use your fingers to gently break off half of the lock buckle, pry open the upper half, and cut off the zip tie.

3.3 Separation and Implementation of Protective Grounding (PE) and Functional Grounding (FE)

The CP69xx manual clearly distinguishes the concepts of protective grounding and functional grounding:

Protective Grounding (PE): According to EN 60204-1 standard, low resistance protective grounding is achieved through Pin 3 of the voltage socket to prevent dangerous touch voltage.

Functional grounding (FE): In order to meet EMC immunity (EN 61000-6-2) and emission limits (EN 61000-6-4), functional grounding must be achieved through the grounding bolts inside the rear shell connection compartment. The manual emphasizes that the functional grounding wire should use a wire or flat conductor with a cross-sectional area of at least 4 mm ², and the circumference of the conductor should be as large as possible (i.e. using multi stranded wire is more effective) to provide a low impedance discharge channel for high-frequency interference.

Attention: One of the common causes of touch screen misoperation is poor functional grounding. If the touch function is abnormal, first check whether the grounding bolt is reliably connected to the central grounding point of the control cabinet.

Chapter 4: Interpretation of Status LEDs

The rear connecting cabin of CP69xx is equipped with six status indicator lights, which facilitate engineers to quickly diagnose the equipment status:

Meaning of LED identification

1. No functional reservation, no definition

2. No functional reservation, no definition

3 USB 1 USB 1 interface is working

4 USB 2 USB 2 interfaces are working

5 Power Good Input voltage is normal (OK)

6 24 V in 24V power supply has been established

Engineering application: If there is no display or touch failure on the panel, the rear LED status can be observed. If both "Power Good" and "24 V in" do not light up, the problem is concentrated on the power supply end; If it is on but not displayed, the video signal link needs to be checked.

Chapter 5: Operating Standards and Cleaning Maintenance

5.1 Restrictions on operating media

To ensure the long-term reliability of the touch screen:

Touch screen: Only fingertips or specialized touch screen pens are allowed. If the operator wears gloves, it is necessary to ensure that the surface of the gloves is free of hard particles such as metal shavings and glass shards, otherwise it will seriously scratch the screen surface.

5.2 Cleaning Mode

CP69xx supports activating the "cleaning mode" through the Beckhoff Control Tool to prevent accidental touch actions during the cleaning process.
