POWER LED is on when the unit is powered. It is off when the unit is not powered.
The START/STOP button has different functions, depending on the analyzer's operation. It is
used to select the scale desired for the current sensors or to start or stop the recording of
electrical parameters. In this case, to start or stop the recording process, hold the button during
3 seconds.
(*) The REC LED has three basic modes. When it is off, the unit is not recording information.
When it is permanently on, the unit is recording electrical parameters, which are stored in the
SD memory card. When the REC LED is flashing, there is an error in the SD memory card. The
REC LED can be flashing for the following reasons:
• No memory card inserted in the unit's SD card slot.
• The memory card inserted does not have the correct format or data can not be written.
(for example, if the card is write protected or it has a FAT32 format; in that case change
the format of the memory card to FAT16).
(**) The LED corresponding to L1/sc1, L2/sc2 and L3/sc3 can also indicate different situations,
depending on the unit's status and during the start-up procedure.
• Should the CIR-e³ unit detects flexible clamps connected during start-up, the LED can
be used to select the scale desired for the current sensors. In this case, reference will be
provided with the legend of the LED shown on the scale (sc1, sc2 or sc3).
• When you have selected the scale (if needed) or the unit detects clamps with a single
scale automatically (so that the scale selection process is not required), the LED will
start flashing to indicate that there is an incorrect connection. The phase LED can
flashing for reasons:
o Incorrect connection of the voltage references. Flashing indicates that
there is an incorrect phase sequence (L1, L2 and L3).
o The unit detects power values with a negative sign (as in the case of
generated power).
o The installation's power factor is under 0.5, i.e., the angle between the
voltage and current corresponding to that phase exceeds 60º. This error
indicates that there is a fault in the unit and we recommend going through
the connections.
CIR-e³ LED’s start flashing to indicate a connection error.
The unit has been installed correctly when the LED’s are permanently on. Is
possible flashing when the angle of cos
ϕ is very bad.
