Aftercooler Coolant Temperature
Parameter Default Setting
Warning setpoint 102 °C (215 °F)
Warning delay 5 seconds
Derate setpoint 107 °C (225 °F)
Derate delay 5 seconds
Maximum time of derating 480 seconds
Hysteresis 3 °C (5.4 °F)
Security level No required password
Maximum derating 25%
Shutdown setpoint 107 °C (225 °F)
Shutdown delay 5 seconds If the aftercooler coolant temperature is above 102 °C (215 °F) for five seconds, a warning will occur. To deactivate the warning, the aftercooler coolant temperature must be below 99 °C (210 °F).If the aftercooler coolant temperature is above 107 °C (225 °F) for five seconds, a derating will occur. The continuous schedule of the derating will reach 25 percent in 480 seconds.When the aftercooler coolant temperature is less than 104 °C (220 °F), the percent of the derating is decreased until full power is restored. However, if the aftercooler coolant temperature rises above the setpoint again, the derating resumes.If the aftercooler coolant temperature is above 107 °C (225 °F) for five seconds, a shutdown will occur. Note: The default settings result in a shutdown that occurs before a derating. These settings are programmed because most customers prefer a shutdown for the aftercooler coolant temperature. The settings can be reprogrammed to different values.
