ReCon T Energy Logger
User manual
This will give voltage, energy and power readings scaled to the actual pump consumption.
Additional safety reminder: ReCon T should never be used to measure directly voltages higher
than 600 V. The current sensors should not be used over copper plates or non-insulated cables
whose working voltages are higher than 600 V. The current sensors can be safely used over
insulated conductors provided that enough distance is kept to any live voltage point.
5. In this panel there are also two options related to the measurement and recording: first checkbox
enables the recording of voltage profiles when an event is detected (sag, swell, RVC) and second
checkbox enables the recording of delivered energy (consumed energy is positive and is recorded
always, whereas delivered energy to the network is negative and can be recorded or not).
6. Finally, user can select the frequency of the network (50 or 60 Hz).
6. Next panel shows two alternating options for reactive power and energy calculation: first option
enables Q measuring from v(t) and *i(t) (i(t) conjugated) and S calculation from measured P and S
(Q is reactive power), and second option enables S measurement (from Vrms and Irms) and Q
calculation from measured P and S (Q is non-active power then).
7. Next panel is only present when instrument runs a firmware equal to or higher than V2.60. These
versions of the firmware incorporates three different recording modes (that will be explained later in
REVISAR): continuous recording (the standard mode, the one present in older firmware versions),
programmed recording (it is a timed recording session with adjustable date and time start and date
and time end) and triggered recording (recording starts when some magnitude reaches a certain
value).
8. The memory panel informs of the amount of memory currently used and gives the possibility of
stopping the recording once the memory is full (linear memory) or alternatively keep recording
discarding the oldest recordings (circular memory).
9. Finally, the last panel provides the possibility of selecting an averaging block size between 1 second
and 60 minutes. The instrument will record maximum, minimum and average values for the selected
interval. Events are still checked every 200 ms with 200 ms values disregarding the value of the
block size. Once the block size is selected, an estimation of the memory capacity (in days) will be
shown, though this depends highly on the measured values.
