KBR multimess F144-2-LED-ESMS...-4
For the wiring of the pulse output, we recommend to exclusively use shielded
twisted pair material to avoid disturbances (e.g. installation line I-Y(ST) Y
2 x 2 x 0.8 mm. The shielding may only be connected on one side).
During installation, please also observe our notes on safety measures against
overvoltage and lightning in chapter "Protective measures" of this manual.
NOTE
Please observe the following when connecting the device to the three-phase
network you want to measure:
- Energy fl ow direction
- Assignment of measuring voltage input / current transformer input
Rotary fi eld:
The device can be operated with a clockwise or counter-clockwise rotary
fi eld. When switching on the device power supply, the multimess F144-2-LED-
ESMS-...-4 automatically checks the direction of rotation. Rotary fi eld check:
Connect only the measuring voltage to the device (Umeas see nameplate).
Switch on the device by applying voltage to the power supply connections (L
and N). Immediately after the device has been switched on, it will check the
power supply rotary direction.
The rotary fi eld is displayed in the menu UPH-PH, submenu Rotary fi eld.
For a clockwise rotary fi eld, the display shows L1 0, L2 120 and L3 240 degrees.
If you want to change the direction of rotation from clockwise to counter-
clockwise, you only have to swap two terminals, i.e. two phases. Then, switch
the device OFF and ON again. The display now shows the correct voltage and
the device starts measuring automatically.
Check again whether the assignment of the voltage path L1 and the current
path L1 as well as all other phases are still correct.
