Installation Guidelines

Unpack and verify all components. Mount in approved industrial enclosure.

1. Mounting: Secure CPU and modules on DIN rail in control cabinet.
2. Power connections: Connect AC mains to power supply; verify voltage (100-240V AC).
3. I/O wiring: Route field cables to appropriate terminals; follow separation guidelines.
4. Network connections: Connect Ethernet cables to designated ports.
5. Grounding: Establish proper earth ground for noise immunity and safety.

WARNING! Disconnect all power before installation. Use appropriate personal protective equipment (PPE).

Initial Configuration

Power on system; access configuration via HMI or engineering software.

1. System initialization: Run startup wizard to detect hardware modules.
2. Network configuration: Set IP addresses, subnet masks, gateway.
3. I/O mapping: Assign physical I/O points to logical variables.
4. User accounts: Create administrator and operator accounts with appropriate privileges.
5. Backup configuration: Save initial setup to memory card.

CAUTION! Document all configuration changes. Test in simulation mode before live deployment.

Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
No power to system	Power supply failure	Check AC input; verify fuse; test power supply output.
Communication failure	Network issues	Verify cables; check IP configuration; restart switch.
I/O point not responding	Wiring/configuration	Check field wiring; verify I/O mapping; test with meter.
Program not executing	Controller mode	Ensure controller in RUN mode; check for major faults.
HMI unresponsive	Touchscreen calibration	Recalibrate touchscreen; restart HMI; check connections.
