B4.8. Shutdown State
The DTSX3000 can be safely powered down when it is in Shutdown (ready-for-power-
down) state.
The states of the LED indicators of the DTSX3000 module are the same in shutdown
state and power-off state but the two states can be distinguished by checking the state
of the LED of the power supply module.
- If the LED of the power supply module is lit, the DTSX3000 is in Shutdown state.
- If the LED of the power supply module is not lit, the DTSX3000 is in Power-off
state.
B4.9. Test Mode
The Test mode is used for fault analysis and system recovery when the system fails to
boot.
The DTSX3000 enters Test mode automatically if the system software is not installed or
a fatal error is detected during system boot.
Contact your Yokogawa service representative if your DTSX3000 is in Test mode.
B4.10. SD Card Error State
The DTSX3000 enters SD Card Error state if it detects an error during SD card
installation check. If this happens, turn off the power and ensure that a SD card is
properly installed. If the DTSX3000 enters SD Card Error state even though an SD card
is properly installed, try replacing the SD card as it may be faulty.
