5.6 Troubleshooting

This section provides guidance in troubleshooting SENtral, and is divided into hardware-

related and software-related errors.

5.6.1 Hardware-Related Error Conditions

Possible indications of a hardware-related problem are given below in Table 5-9.

In the event of such errors, SENtral will enter Standby State, shut down the sensors, and

generate an interrupt to the host. Possible reasons for hardware-related errors include

problems with an external EEPROM upload, power transients detected by power

management, and errors in software detected by Watchdog. Often the error can be

cleared by sending the ResetReq command and reloading the Configuration File.

5.6.2 Software-Related Error Conditions

Possible indications of software-related errors are given below in Table 5-10:
