Installation environment: DCS control cabinet, on-site control panel, suitable for industrial sites with high humidity, dust, and corrosive gases.

Usage and maintenance instructions Use

Installation: Securely attach to a standard DCS cabinet, leaving sufficient space for wiring and heat dissipation;

Wiring: Plug in the 50-pin flat cable firmly and lock it in place. For the on-site transmitters, connect the cables to the press-fit terminals according to the specifications to ensure a secure connection;

Power-on and Debugging: After wiring is completed, start the DCS and check for no fault alarms. Verify the accuracy of the on-site signal reading before putting it into operation. Maintenance

Environmental Maintenance: Keep the cabinet clean and well-ventilated, and avoid prolonged exposure to damp and corrosive substances;

Regular Inspection: Check the connection status of terminals and cables every quarter, and replace damaged components in time;

Cleaning and Protection: Use a dry soft cloth to wipe off surface dust; Do not allow liquid cleaners or abrasive tools to come into contact with the circuit board and terminals;

Storage and Anti-static: Store spare parts in anti-static bags and place them in a cool and dry place; Take anti-static measures during handling to prevent damage from static electricity to components;

Prohibition of Self-Dismantling: Non-professionals are not allowed to disassemble the equipment to prevent damage to the internal circuits.
