8 Configuring the Recorder
D03283R01.10 TESLA LITE User Manual 8-23
Scale Factor Specifies a multiplier for each of the inputs. The scale factor is applied
in the secondary domain.
Angle Offset Specifies a phase angle shift to be applied to each of the inputs.
Note that when an offset is specified, a high speed summation record-
ing - which uses sample by sample addition rather than phasor addi-
tion - is not generated. All other functions, including low speed
recording, are available and will reflect the offset.
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 .
Delay Specifies how long the trigger condition must be present before a trig-
ger is declared. 0 to 1,200 seconds in half-cycle increments.
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.
Priority Specifies the priority to be assigned to records created by this trigger.
The priority is used to determine Central Station notification.
1 - 3 (3 is the highest priority). (“Notify” on page 7-13).
Alarm Contact Specifies a rear panel contact to be closed when triggered. Contacts
are closed momentarily for one second. Contact assignment is not
exclusive, allowing multiple triggers to activate the same contact.
Contacts assigned for storage alarms (“TESLA Alarms” on page 8-6)
will not be available for use here.
