11.1 Using the External Control Terminal
Event output terminal (EVENT OUT)
This informs an external device when anom-
alies occur within the PQ3198.
When you connect the event output terminal
to a trigger input terminal on a waveform
recording device such as the Hioki Memory
HiCorder, you can record waveforms on the
Memory HiCorder when events occur.
See: "Using the event input terminal (EVENT
OUT)" (p.178)
Event input terminal (EVENT IN)
Used to start and stop recording and analyze
anomalies based on the operational timing of
an external device.
When you connect the search signal of an
anomaly search device such as an overcur-
rent relay to the event input terminal, you can
analyze anomalies using
this device according to anomaly operations.
See: "Using the event input terminal (EVENT IN)"

To avoid damaging this device, do not input voltages outside the ranges
-0.5 V to +6.0 V (EVENT IN) or -0.5 V to +6.0 V (EVENT OUT) to the
external control terminals.
•To use the external control terminal to start or stop recording based on an exter-
nal signal, set the external control (IN) setting to START/STOP.
•To use the external control terminal to provide external event functionality, make
the following two settings:
•
Set the external event to
ON
.
( [SYSTEM] - DF3 [Power/etc] - [External Event: ON] )
See: "Generating events using an external input signal (external event settings)" (p.92)
•
Set external control (IN) to Event.
