24 PEBB Over Temp.
Analog The temperature of the heat-
sink over the parameter [Heat-
sink OT Level] (Analog) Possible problem
• PEBB fan failure
Solution(s)
• Clean the filters
• Inspect and if necessary clean the
heat-sink fins
• Change the PEBB Fan
25 PEBB Over Temp.
Digital The temperature of the heat-
sink over 100°C(Digital) Possible problem
• PEBB Fan Failure
Solution(s)
• Inspect and if necessary clean the
heat-sink fins Change the PEBB Fan
30 Grid Over Voltage
