Grounding requirements: Class D grounding (grounding resistance ≤ 100 Ω), separated from the AC panel grounding main line, with a spacing of ≥ 15m.

 Installation and commissioning process

1. Key steps and requirements for installation

(1) Preliminary preparation

Confirm installation environment: temperature 0-55 ° C, humidity 10-90% RH, no corrosive gases, dust concentration ≤ 0.1mg/m ³;

Grounding preparation: Construction shall be carried out in accordance with Class D grounding standards, with a grounding resistance of ≤ 100 Ω, and multiple cabinets shall be connected to the ground using a daisy chain connection;

Tool preparation: Use calibrated measuring instruments and compatible screwdrivers (tightening torque 1.0-1.5N · m).

(2) Installation process

Installation base: fixed on the vertical surface of the cabinet, using M5 screws (tightening torque 1.5N · m) to ensure that the insulation lining does not fall off and the metal part of the base does not touch the control cabinet;

Module assembly: Install in the order of "power module → RI/O-IF module → CPU module → option module → PI/O module", align the module with the guide rail, insert it vertically, and tighten the screws;

Battery connection: Before installing the CPU module, insert the main battery cable into the connector according to the corresponding color, and cover the battery cover tightly (hear a snap sound);

Wiring specifications:

Power cable: ≥ 2mm ² shielded twisted pair, with a distance of ≥ 100mm from the network cable;

Remote I/O cable: Select according to the transmission distance (0.75mm ² cable for long distances, ≤ 300m), with single ended grounding of the shielding layer (RI/O-IF side);

Grounding wiring: The FG terminal is connected in a daisy chain and ultimately connected to the power module FG terminal. The cable cross-section is ≥ 2mm ² (inside the cabinet)/≥ 5.5mm ² (outside the cabinet).

(3) Installation gap requirements

The distance between the cabinet and the unit is ≥ 100mm, and the distance between the sides is ≥ 50mm;

There is a requirement for no distance between modules, but one empty slot needs to be left between the high-voltage PI/O module (≥ 100VAC/48VDC) and the CPU/option/simulation module;

Cooling measures: The cabinet needs to have air vents or install fans to ensure that the intake temperature is ≤ 55 ° C.

2. Debugging core processes and tools

(1) Debugging Tools and Environment

Tool: BASE SYSTEM/S10VE (requires administrator privileges to install), supports Windows 7/10 (64 bit), PADT needs to meet 1GHz CPU, 2GB memory, 200MB free hard disk;

Connection: Connect PADT to CPU module ET1/ET2 ports via Ethernet cable, with default IP address 192.192.192.1 (ET1)/192.192.193.1 (ET2).

(2) Debugging key steps

Project creation: Start BASE SYSTEM, create a new project and configure PC numbers and comments, enable C mode requires installation of RPDP;

Network configuration: Set the IP address, subnet mask, and routing information of the CPU's built-in Ethernet or ET.net module, write them, and restart the system;

Program download: Write the program using LADDER DIAGRAM SYSTEM/HI-FLOW SYSTEM, download it to the CPU module, and confirm that there are no syntax errors;

Parameter configuration: Set PI/O installation status, partition (FIX/FREE), I/O point count, remote I/O synchronization mode, etc;

System startup: Turn the CPU RUN/STOP switch to RUN, observe that the RUN LED is constantly on, and confirm that there are no error codes through the indicator;

Function verification: Monitor memory data through MCS function, view module status and error logs through RAS menu, and verify that I/O signal acquisition and execution are normal.

3. Operations and troubleshooting

(1) Key points of daily operation and maintenance

Regular inspection: monthly check the tightness of module screws, LED status, and cable connections; Clean ventilation ducts and verify grounding resistance annually;

Backup strategy: Regularly backup CPU data, including main memory and MRAM data, through the BACKUP STORE SYSTEM, and backup files need to be stored remotely;

Module replacement: It is recommended to replace the power module within 10 years (the lifespan of the aluminum electrolytic capacitor), and replace the main battery within 5 years. When replacing, the power should be turned off;

(2) Common troubleshooting

LED fault indication:

ERR LED constantly on: CPU module has a serious error. Check the error code through the indicator (such as ECF=xxxxx) and refer to the manual for troubleshooting;
