Check CC Module Temperature

Access MOD function and navigate to System Info > Drive Status to check CC temperature readings. Normal operating temperature should be below 60°C.

Use the TNC's built-in temperature monitoring in the drive diagnostics screen

Inspect Cooling System

Verify cabinet fans are operational and air filters are clean. Check for blocked ventilation around the CC module housing.

Ensure main power is OFF before opening electrical cabinet

Allow Cool-Down Period

Power down system for 30 minutes minimum to allow CC module to cool. Monitor ambient temperature in electrical cabinet.

Install additional cooling if ambient temperature consistently exceeds 40°C

Reset and Monitor

Power up system and monitor CC temperature continuously through MOD > System Info during operation to verify cooling effectiveness.

Measure 24V DC Supply

Use multimeter to verify 24V DC at CC module terminals. Voltage should be 24V ±10% (21.6V - 26.4V) under load.

Use proper PPE and lockout procedures when measuring live voltages

Check Power Supply Loading

Verify total current draw on 24V supply does not exceed rated capacity. Disconnect non-essential 24V loads temporarily for testing.

Check machine parameter MP7300 for configured power supply ratings

Inspect Power Connections

Check all 24V DC connections to CC module for looseness, corrosion, or burning. Verify proper torque on terminal connections.

Use thermal imaging camera if available to identify hot connections

Test Supply Under Load

Monitor 24V supply voltage while cycling machine functions to identify voltage drops during peak current demands.

Check CC Status LEDs

Examine LED indicators on CC module. Normal operation shows steady green power LED and communication LED activity.

Refer to CC module label for LED status code meanings

Verify Communication Cables

Inspect and reseat all communication cables between TNC and CC module. Check for damaged shielding or bent connector pins.

Power down system before disconnecting communication cables

Perform CC Module Reset

Execute hardware reset of CC module using reset button or power cycle sequence as specified in CC documentation.

Some CC modules require specific reset sequence timing

Test with Spare Module

If available, substitute known good CC module to isolate hardware failure. Transfer parameter settings if replacement resolves issue.

Check TNC System Status

Access MOD function > System Info > Hardware to verify TNC communication interface status and error counters.

Look for communication timeout errors in the system log

Verify Interface Parameters

Check machine parameters MP6xxx series for CC communication settings including baud rate, timeout values, and interface type configuration.

Compare current parameters with machine documentation or backup file

Test Communication Loop

Use TNC diagnostic functions to test communication loop integrity between control and CC module.

Ensure proper grounding of communication cables to prevent interference

Restart TNC Communication

Perform controlled restart of TNC communication services through MOD > System > Restart Communication to re-establish CC link.
