SEL ASCII Protocol and Commands
For more information on metering and example responses for each meter
class, see Section 5: Metering and Monitoring.
On issuing the MET c R command for resetting metering quantities in class c,
the relay responds:
Reset Metering Quantities (Y,N)?
Upon confirming
(pressing Y), the metering quantities are reset and the relay responds with
Reset Complete
.
OPEN n Command (Open Breaker n)
The OPE n (OPEN) command asserts the Relay Word bit OC n for 1/4 cycle
when it is executed. Relay Word bit OC n can then be programmed into, for
example, the TRn SEL
OGIC
control equation to assert the TRIPn Relay Word
bit, which in turn asserts an output contact (for example, OUTxxx = TRIPn) to
open a circuit breaker (see Table 4.53 and Figure 4.127 through Figure 4.129
for factory-default settings and trip logic). Select n = X or n = Y for Breaker X
or Breaker Y, respectively.
To issue the OPE X command, enter the following.
Typing N <Enter> after the previous prompt aborts the command.
The OPE command is supervised by the main board Breaker jumper (see
Table 2.15). If the Breaker jumper is not in place (Breaker jumper = OFF), the
relay does not execute the OPE command and responds with the following.
