Exhaust Temperature Absolute
Limit
Exhaust temperature is above absolute limit*
• Alarm or warning depending on option 13
• Check exhaust gas readings and parameter 97
Incorrect/no load sensor detected
• Check option 1
• Check wiring on terminals 37 – 39
3mA or lower received from 4-20mA external modulation/
external setpoint
• Check parameter 69
• Check feedback from external modulation/ external setpoint controller
• Check wiring on terminals 7 – 9
