User and maintenance instructions Instruction Manual

When the power is off, insert the controller into an empty slot of the standard 3U PXIe chassis and tighten the fixing screws. After confirming that the backplane connection of the chassis is normal, turn on the power. Connect external devices such as monitors, keyboards, mice, and network cables as needed, and complete the installation and configuration of the operating system and application software. After powering on, check the identification status of all modules in the chassis through NI-MAX, confirm that the hardware is normal, and then run the test program. When using the real-time control function, complete the system mode switching and parameter settings according to the software instructions. During the operation of the equipment, avoid severe vibrations and hot-plugging operations, and ensure that the network cables and peripheral cables are securely connected.

Maintenance Instructions

Regularly use a dry soft cloth to wipe the equipment casing and various interfaces, remove surface dust, and strictly prohibit contact with liquids to prevent short circuits and interface corrosion. Regularly clean system redundant files, logs, and caches to release disk space and maintain read/write efficiency. When the equipment is running continuously for a long time, regularly check the overall heat dissipation of the chassis to avoid poor heat dissipation due to dust accumulation. When the equipment is idle for a long time, store it in a dry environment with a temperature range of -20°C to 60°C and a relative humidity of less than 60%. When the equipment has abnormal startup, peripheral failure, or communication interruption, prioritize checking the power supply, wiring, and system services; when the system runs slowly or has lag, check the background programs, memory, and disk usage.
