The front panel targets can be reset to TAR 0 and cleared remotely or locally using the
TARGET command. Type TARGET R <ENTER> to reset and clear the targets.
To check the internal clock, type TIME <ENTER>. To set the clock, type TIME
followed by the desired setting and <ENTER>. Separate the hours, minutes, and seconds
with colons, semicolons, spaces, commas or slashes. For example, to set the clock to
23:30:00, enter: TIME 23 30 00 <ENTER> or TIME 23:30:00 <ENTER>, etc.
A quartz crystal oscillator provides the time base for the internal clock. The SEL-267D relay
time code input may be used to synchronize its clock to an external clock with a demodulated
IRIG-B time code output.
Type TRIGGER <ENTER> to generate an event record. The relay transmits a response of
"Triggered." The computer formats the just-triggered record (after a short delay), and a
summary of the record is displayed.
The TRIGGER command is useful when inspecting phasor voltages and currents. When the
SEL-267D relay is first installed, execute the TRIGGER command, draw the phasors (the
EVENT REPORTING section explains how to do this), and check for the proper polarity and
phase-sequence of the inputs.
Event records may also be generated without control action by asserting the EXTERNAL
TRIGGER input.
Access Level 2 Commands
All commands are available from Access Level 2. However, the commands listed below are
available only from Access Level 2. Recall that any attempt, successful or otherwise, to enter
Access Level 2 causes the ALARM relay to assert for one second.
The CLOSE output relay may be closed by executing the CLOSE command or asserting the
DIRECT CLOSE input as long as the 52A input is not asserted. The CLOSE output relay
