Energising the terminal
When the terminal is energised the window on the local HMI remains dark. After 10 seconds the
green LED starts flashing and after approximately 30 seconds the window lights up. After an-
other 10 seconds the window displays ‘Terminal Startup’ and after about 30 seconds the main
menu is displayed. The upper row should indicate ‘Ready’. A steady green light indicates a suc-
cessful startup.
Figure 13:
Typical terminal startup sequence
If the upper row in the window indicates ‘Fail’ instead of ‘Ready’ and the green LED is flashing
an internal failure in the terminal has been detected.
See the self supervision function
in this
chapter to investigate the fault.
After startup the appearance of the local HMI should be as shown in
