Notes: table 10.34
1) The standard data recorder can be triggered by a Timer (the internal clock) or by Setpoint .
In trigger mode 2 when the setpoint goes active, the recorder starts to record, and when the
setpoint becomes inactive, the data recorder stops.
2) Recording delay: In Trigger mode 1, a fixed time can be set in seconds to delay the start of the
measurement (triggered by timer). Example: When the delay is set to "300", the measure-
ment will start 300 s (= 5 minutes) after the timer period has elapsed. In order to obtain eval-
uable results, the programmed value of the recording delay parameter should be less than
that of the recording interval parameter. For Trigger mode 2, recording delay is ignored.
3) For standard data recorders all the measured quantities 0…328 from table 8.3.2 can be used.
10.14 Waveform recording (WFR)
The PEM575 provides two waveform recorders capable of recording waveforms in-
dependently from one another (waveform recorder WFR1 and WFR2). The total ca-
pacity of WRF 1 and WFR 2 is 32.
Each waveform recorder can simultaneously record 3-phase voltage and current si-
gnals at a maximum resolution of 256 samples per cycle.
The data recorder is only operational when the offset e1, +2, +3
and +6 are all non-zero !
Modifying an offset parameter will clear the DR log and reset the pointer
to 0.
