SEAL-O-RING 1241858 - Caterpillar

Some generators are equipped with optional 100 Ohm Resistance Temperature Detectors(RTD) that are mounted in slots of the main stator. The generator set is equipped with RTD modules that are interfaced to Electronic Modular Control Panels (EMCP). The modules can be interfaced to measure the temperature of the stator. Alternately, there are measuring devices in the open market that can be interfaced with the RTD. Caterpillar recommends the continuous monitoring of the RTD.Refer to the specifications in table 1 for the maximum temperatures of the setpoints.
Table 1
Maximum Recommended Temperatures for the Setpoint(1)
Generator set application Alarm Shutdown
Standby 180 °C (356 °F) 190 °C (374 °F)
Continuous 155 °C (311 °F) 165 °C (329 °F)
(1) If the operating temperature is lower than the recommended setpoints, adjust the alarm and shutdown setpoints to a lower value to ensure that unusual temperature variances are recognized.
