WebEML User Manual Perform protection switching
1003
Automatic Switch is the normal operation condition: the position of the switch
depends on the commands generated by the logic.
Manual has the lowest priority: it is performed only if there are no alarms that can
activate an automatic switch. It cannot be performed if Lockout or Forced commands
are already activated. If this command is active, it will be removed by an incoming
alarm. This command does not activate signaling ABN.
Table 7 Command priority list, The “Forced” command for channel 1 is equivalent to
the “Lockout” command for channel 0. In both cases, the result is that the relevant
channel protection path is forced to standby status.
