Frequency derived
from Identifies the analog input channel on which to measure frequency. A
voltage channel is recommended for best results.
Trigger Settings
Rate of Change
Interval Specifies the period of time over which both positive and negative rate
of change is measured. 0.5 to 8.0 cycles.
Limit Specifies the trigger levels for the magnitude triggers and the magni-
tude portion of the rate for the rate of change triggers. The period por-
tion of the rate is specified by the
Rate of Change Interval.
The high magnitude limit is 7/6 x nominal frequency, low magnitude
limit is 5/6 x nominal frequency.
Delay Specifies how long the trigger condition must be present before a trig-
ger is declared. 0.0333 (2 cycles) to 1,200 seconds in half-cycle incre-
ments.
Trigger Actions
Enable Enables or disables the associated trigger. A trigger can be disabled
without altering the rest of its settings.
Fault Initiates a fault (high speed) recording when triggered.
Swing Initiates a swing (low speed) recording when triggered.
If both Fault and Swing are enabled, the recorder will attempt to cre-
ate a combined record.
Log Logs a message in the Event Log when triggered.
Notify Contacts the RecordBase Central Station when triggered. Can be
used to initiate wide area swing recordings and/or automated record
transfer (“Notify” on page 7-13.)
Cross Trigger Activates the cross-trigger contact (#6) to trigger another device.
