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
SEL
OGIC control equation to assert the CLOSE Relay Word bit, which in turn
asserts an output contact (e.g., OUT102 = CLOSE) to close a circuit breaker.
See Figure 6.1.
See the Note in the Set Close on page 6.2 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>
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.
