Heatsink overtemperature warning power supply unit

What does E350 mean?

The heatsink temperature of the Indramat HVE or HVR power supply unit has reached its permissible limit, opening the temperature pre-warning contact. Power will be switched off after 30 seconds if the condition persists, indicating potential thermal overload of the DIAX04 SSE-03VRS.

• The load on the power supply unit is too high, leading to excessive heat generation.
• The ambient temperature within the control cabinet or operating environment is above the specified limit.
• Cooling air ducts are blocked, restricting airflow to the heatsink.
• The internal cooling blower of the HVE/HVR unit is defective or obstructed.

Click steps to track your progress.

1. 1

   Reduce the operational load on the power supply unit to decrease heat generation.

2. 2

   Measure and reduce the control cabinet's internal temperature to within specified operating limits.

3. 3

   Inspect and clear any obstructions in the cooling air ducts or ventilation openings of the Indramat DIAX04 SSE-03VRS power supply unit.

4. 4

   Verify the operation of the internal blower; if it's defective, the power supply unit requires replacement.
