Maintenance
- Routine inspection: Check module LED status, terminal tightness and CS31 bus connector condition every 6–12 months
- Clean dust on module housing with dry compressed air; liquid solvent cleaning is strictly prohibited
- ESD protection must be applied during disassembly, anti-static wristband required
- If communication failure occurs, inspect bus cable shielding, terminal connection and station address setting
- Stop power supply immediately if condensation, corrosion or burn marks are found
- We support function testing, refurbishment and spare replacement service for this CPU unit
Installation
- Cut off the 24VDC power supply of control cabinet and confirm zero voltage before operation.
- Wear anti-static wristband to prevent electrostatic damage to internal electronic components.
- Clip CS3107KT93 module onto 35mm DIN rail inside cabinet and lock mounting buckle.
- Wire 24VDC power supply, digital field signals and system bus cable to corresponding terminals.
- Double-check wiring polarity and tightness to avoid short circuit.
- Connect RS232 programming cable, download control program and configure station parameters.
- Restore cabinet power supply, check RUN LED status and verify bus connection with remote I/O modules.
- Perform field signal test, no-load commissioning and validate control logic and interlock functions.
