CLO Command (Close Breaker)
The CLO (CLOSE) command asserts Relay Word bit CC for 1/4 cycle when it is executed. Relay
Word bit CC can then be programmed into the CL SELOGIC Control Equation to assert the
CLOSE Relay Word bit, which in turn asserts an output contact (e.g., OUT2 = CLOSE) to close a
circuit breaker. See Figure 6.1.
See the Note in the Set Close discussion, following Figure 6.1, for more information concerning
Relay Word bit CC and its recommended use, as used in the factory settings.
To issue the CLO command, enter the following:
=>>CLO <ENTER>CLO <ENTER>
Close Breaker (Y/N) ? Y <ENTER>Y <ENTER>
Are you sure (Y/N) ? Y <ENTER>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 2.6 and Table 2.7).
If the Breaker jumper is not in place (Breaker jumper = OFF), the relay does not execute the CLO
command and responds:
Aborted: No Breaker Jumper
