The Function of Monitoring the Aftercooler Coolant Level on Certain Gas Generator Sets Has Changed {1063, 1395}
- Engine:
- G3406 (S/N: R7E103-UP; KAR264-UP)
- G3412 (S/N: KAP223-UP)
Description of Change: The function of monitoring the coolant level in the aftercooler circuit of G3406 and G3412 TA (turbocharged/aftercooled) generator sets has been changed.
Previously, the aftercooler coolant level was monitored by a sensor located in the radiator. The new design eliminates this sensor and alternatively uses the High Inlet Air Temperature Switch (HIATS) located in the aftercooler. The HIATS monitors the aftercooler air temperature which is directly affected by the coolant temperature and level. This change has improved the reliability of the product.
Adaptable To: This wiring change is Effective with the following serial numbers:
- G3406: KAR00264, R7E00103
- G3412 TA: KAP00223
- G3406: KAR00001-00263, R7E00001-00102
- G3412 TA: KAP00001-00222
