System Monitor, Metering, and Load Profile Functions for further details on the breaker
monitor.
CLO Command (Close Breaker)
The CLO (CLOSE) command asserts Relay Word bit CC for ¼ cycle when it is executed. You
can program Relay Word bit CC into the CL SEL
OGIC
Control Equation (see Figure 1.20) to
assert the CLOSE Relay Word bit, and, in turn, to assert an output (RCCL = CLOSE; see
Figure 7.29) contact to close a recloser.
See the Close Logic subsection in Section 6: Close and Reclose Logic for more information
concerning Relay Word bit CC and its recommended use.
To issue the CLO command, enter the following:
=>>CLO <ENTER>
Close Breaker (Y/N) ? Y <ENTER>
Are you sure (Y/N) ? Y <ENTER>
=>>
Typing N <ENTER> after either of the above prompts will abort the command.
The CLO command is supervised by the main board Breaker jumper (see Table 2.4 and
Table 2.5). If the Breaker jumper is not in place (Breaker jumper = OFF), the control does not
execute the CLO command and responds:
Aborted: No Breaker Jumper
GRO n Command (Change Active Setting Group)
The GRO n command changes the active setting group to setting Group n . For example, to
change to settings Group 2, enter the following:
==>GRO 2 <ENTER>
Change to Group 2
Are you sure (Y/N) ? Y <ENTER>
Active Group = 2
==>
The SEL-351P switches to Group 2 and pulses the ALARM contact. The control automatically
outputs the Group Switch Report on all ports with the serial port setting AUTO = Y. An
example Group Switch Report is shown below:
