• Continuous Mode: Enabled by setting
sampling time the logger will record the actual value(s) programmed and store them
in the log. Up to 4096 data samples per channel will be recorded after which the
oldest data is replaced by newly sampled data.
• Trigger Mode: Enabled by setting
actual value(s) for up to the last 15 events are recorded, each in a separate buffer. The
amount of pre-trigger data to record is also selectable. Before the trigger occurs, pre-
trigger data is gathered as required. When the programmed trigger condition takes
place, data is collected until the buffer is filled, pre-trigger data collection begins in the
next buffer and the relay then waits for the next trigger. Once all buffers have been
filled, the oldest data is overwritten when a new trigger occurs.

channel stored for each trigger. For example, "4 x 1024" indicates that the last three
triggers with 1024 data samples per channel can be stored in memory. Note that one
buffer must be reserved for capturing the next event. The
selects the amount of each buffer to be allocated for pre-trigger data. If set to "0%", data
collection effectively starts once the trigger occurs. If set to 100%, only pre-trigger data will
be recorded in the buffer.
If a trigger occurs before the programmed amount of pre-trigger data is collected, the
remainder of the buffer will be filled with post-trigger data until it is full. Actual values in the
memory map provide information as to where the true trigger position is in each log buffer.

If all Channel Sources (1 through 8) are set to "Disabled", then the data logger will not
collect data in continuous mode or respond to triggers in trigger mode.
