6. Installation and maintenance

1. Installation

Select standard free slots of the Ovation cabinet, reserve ventilation space (≥5cm), away from strong interference equipment such as large power frequency converters, motors, transformers. Wear anti-static wristbands, push the module steadily to ensure reliable contact of the backplane bus, lock the panel screws. In redundant configuration, install two modules of the same specification in adjacent slots for convenient wiring and maintenance, and it is recommended to reserve redundant space.

2. Wiring Connect the module and controller, as well as I/O cards, using Ovation dedicated shielded communication cables. Distinguish the positive and negative poles of the signals, properly tighten the terminals to avoid loosening and overheating. The shield layer is grounded at one end and is separated from power cables, strong current cables, and switch quantity cables (with a spacing of ≥ 30 cm) for reducing electromagnetic interference. After wiring is completed, check the lines to ensure there are no short circuits, incorrect connections, or polarity reversals, and test the communication connectivity to be normal.

3. Daily Maintenance

Conduct regular inspections of indicator light status, module appearance, and wiring terminals, checking for overheating, loosening, corrosion, and dust accumulation; view the processor load, module temperature, communication status, redundancy synchronization situation, and fault records through the system diagnostic log; clean the surface dust with a dry soft cloth or low-pressure clean air at regular intervals (monthly); shorten the cleaning cycle in high dust/high humidity environments (every two weeks); prohibit wiping with corrosive liquids; check the tightness of the wiring terminals every quarter to avoid loosening.

4. Fault Handling

Communication abnormality: Check the indicator lights, wiring terminals, bus cables, and redundant links, identify the surrounding interference sources, and reinsert the module or replace the communication cables;

Redundancy out of synchronization: Check the module parameter configuration, synchronous cable connection, firmware version consistency, and hardware health status, and re-synchronize or upgrade the firmware;

Operation failure (red light alarm): Locate the fault by combining the system alarm code (such as overheating, overcurrent, hardware damage), perform hot swapping replacement, and the system will automatically identify the synchronization program and data after the new module is installed, test it to be normal, and then put it into operation. The faulty module should be stored in an anti-static sealed container and returned to the factory for repair.
