Cross-Reference Information for Event Codes
Event codes are generated when abnormal operating conditions exist. Table 1 is a list of the event codes for the well stimulation pump. The event codes are cross-referenced with the appropriate procedure that can be used to troubleshoot the code.Portions of this material are reprinted with permission from SAE J1939DA_201607 © 2016 SAE International.

An active event code represents a problem with well stimulation pump operation. Correct the problem as soon as possible.Active event codes are listed in ascending numerical order. The code with the lowest number is listed first.Illustration 1 is an example of the operating range of a sensor.
Illustration 1 g01365757
Example of the typical operating range of a sensor
(1) This area represents the normal operating range of the well stimulation pump parameter.
(2) In these areas, the well stimulation pump is operating in an unsafe operating range of the monitored parameter. An event code will be generated for the monitored parameter. The sensor circuit does not have an electronic problem.
(3) In these areas, the signal from the sensor is outside of the operating range of the sensor. The sensor circuit
