Shutdown
There are three system shutdown methods:
1.
150 ms signal from the System I/O line to the PLC line
2.
Press the control system
Power
button on the Home screen.
3.
Turn off the
Isolation
switch on the Control System front panel.
Failure to shut down the system using the correct procedure may damage the system.
Only use the isolation switch on its own to shut down the system in an emergency as a
last resort to remove power from the system.
Once activated, the first two safe shutdown methods follow the same sequence. The
screen shows the shutdown of the system and goes blank. Once the screen has gone
blank, wait thirty seconds and set the isolation switch to OFF to remove power from
the console and from the components of the system on the line.
