Heatsink overtemperature warning power supply unit

¿Qué significa E350 ?

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.

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.
