Recording Time Windows - ABB Tmax T7 Operating Instructions Manual

By means of Ekip Connect, customized Stop Sources can be set via system bus or test bus to coincide with events (a list of
examples is given in the table below)
N° (decimal) Event
1920 Time delay G
2894 sensor L1, L2 or L3 error, or Trip Coil error
2688 LC1 alarm
2049 G alarm
33672 CB connected and springs loaded
1793 Harmonic distortion > 2.1
You can combine the status bits with logical functions "and" or "or" within the same group of events (bytes). Consult the Modbus
Interface document for further details.
The stopping delay can be set from 0.00 [s] to 10.00 [s] with 0.01 [s] steps.
WARNING: If a trip occurs, this data storage process will be stopped after 10 ms, even if a longer stopping
delay has been selected.

Recording time windows

The data logger's measurements are recorded in a time window, the duration of which is defined and synchronized by an event
(trigger/stop event) of your choice.
The following figure displays the time window, the trigger and the samples available in gray:
Samples
1/Freq
The user can select the sampling frequency, the type of stop trigger event and the stop delay so as to obtain the desired pre-
trigger for the selected event.
Depending on the set value, the stop delay can be nil, or less or more than the recorded duration, as shown in the figure below:
Stopping delay = 0
WARNING: If datalogger parameters are changed whilst the datalogger is active, the storage that is in progress
will be terminated and new storage will start on the basis of the new parameters (following a trigger restart
command).
Recording time may be lower than maximum time attainable when the sum of stopping delay and time elapsing between a restart
trigger and a trigger is lower than the maximum value, as described in the figure below:
