¿Qué significa F318 ?

The DIAX04 SSE-03VRS power supply unit's internal heatsink temperature has exceeded its maximum safe operating limit, resulting in a shutdown. This protects the power components from thermal damage. It typically signifies insufficient cooling or sustained overloading of the power supply unit.

• Ambient temperature in the control cabinet is too high for the DIAX04 SSE-03VRS power supply unit.
• Cooling fan on the power supply unit is blocked, dirty, or faulty.
• Heat sink fins of the power supply unit are clogged with dust or debris, impairing heat dissipation.
• The DIAX04 SSE-03VRS power supply unit is overloaded, drawing continuous current beyond its rating.
