•
Vb OVERVOLTAGE TRIG LEVEL:
Once the phase B voltage equals or increases above this setpoint
value, the trace memory is triggered and data on all inputs are captured in the buffer. The number of cycles
captured depends on the value specified in the
TRACE MEMORY USAGE
setpoint. Phase to neutral levels are
used regardless of the VT wiring.
•
Vc OVERVOLTAGE TRIG LEVEL:
Once the phase C voltage equals or increases above this setpoint
value, the trace memory is triggered and data on all inputs are captured in the buffer. The number of cycles
captured depends on the value specified in the
TRACE MEMORY USAGE
setpoint. Phase to neutral levels are
used regardless of the VT wiring.
•
Va UNDERVOLTAGE TRIG LEVEL:
Once the phase A voltage is equal to or less than this setpoint value,
the trace memory is triggered and data on all inputs are captured in the buffer. The number of cycles cap-
tured depends on the value specified in the
TRACE MEMORY USAGE
setpoint.
•
Vb UNDERVOLTAGE TRIG LEVEL:
Once the phase B voltage is equal to or less than this setpoint value,
the trace memory is triggered and data on all inputs are captured in the buffer. The number of cycles cap-
tured depends on the value specified in the
TRACE MEMORY USAGE
setpoint.
•
Vc UNDERVOLTAGE TRIG LEVEL:
Once the phase C voltage is equal to or less than this setpoint value,
the trace memory is triggered and data on all inputs are captured in the buffer. The number of cycles cap-
tured depends on the value specified in the
TRACE MEMORY USAGE
setpoint.
•
SWITCH INPUT A TRIG:
If the setpoint is set to
OPEN-TO-CLOSED
, the trace memory is triggered and data
on all inputs are captured in the buffer on a switch A close transition. If the setpoint is set to
CLOSED-TO-
OPEN
, the trace memory is triggered and data on all inputs are captured in the buffer on a switch A open
transition. The number of cycles captured depends on the value specified in the
TRACE MEMORY USAGE
set-
point.
•
SWITCH INPUT B TRIG:
If the setpoint is set to
OPEN-TO-CLOSED
, the trace memory will be triggered and
data on all inputs are captured in the buffer on a switch B close transition. If the setpoint is set to
CLOSED-
TO-OPEN
, the trace memory is triggered and data on all inputs are captured in the buffer on a switch B open
transition. The number of cycles captured depends on the value specified in the
TRACE MEMORY USAGE
set-
point.
•
SWITCH INPUT C TRIG:
If the setpoint is set to
OPEN-TO-CLOSED
, the trace memory is triggered and data
on all inputs are captured in the buffer on a switch C close transition. If the setpoint is set to
CLOSED-TO-
OPEN
, the trace memory is triggered and data on all inputs are captured in the buffer on a switch C open
transition. The number of cycles captured depends on the value specified in the
TRACE MEMORY USAGE
set-
point.
•
SWITCH INPUT D TRIG:
If the setpoint is set to
OPEN-TO-CLOSED
, the trace memory is triggered and data
on all inputs will be captured in the buffer on a switch D close transition. If the setpoint is set to
CLOSED-TO-
OPEN
, the trace memory is triggered and data on all inputs are captured in the buffer on a switch D open
transition. The number of cycles captured depends on the value specified in the
TRACE MEMORY USAGE
set-
point.
•
TRACE MEMORY TRIGGER DELAY:
In some applications it may be necessary to delay the trigger point
to observe the data before the fault occurred. The PQM allows the trigger to be delayed by the amount of
cycles set in this setpoint. Therefore, buffer will always contain the number cycles specified in this setpoint
before the trigger point and the remaining space in the buffer is filled with the cycles after the trigger point.
•
TRACE MEMORY TRIGGER RELAY
: The relay selected here will be activated upon the occurrence of a
Trace Memory Trigger. This relay will be cleared once the Trace Memory is re-armed.
See the application note in Section A.1.4: TRIGGERED TRACE MEMORY RESOLUTION for additional
details.
