9.2.2 Average current
In the case of single-phase connection, the display
shows the current in the neutral lead.
In the case of three-phase connection, the display
shows the average current of all three phases, calcu-
lated as follows:
9.2.3 Average voltage
In the case of single-phase connection, the display
shows the mains voltage U
L-N
.
In the case of three-phase connection, the display
shows the average mains voltage of all three
phases, calculated as follows:
9.2.4 Tempcon sensor
Actual motor temperature measured with a Tempcon
sensor.
It is presumed that the motor incorporates a Temp-
con sensor, and that the function is active. See sec-
tion 9.4.8.
9.2.5 Pt100/Pt1000 sensor
Actual temperature measured with a Pt100/Pt1000
sensor.
It is presumed that a Pt sensor has been connected,
and that the function is active. See section 9.4.9.
Note: The learning function registers whether a
Pt100/Pt1000 sensor is connected. When using a
three-core Pt-sensor connection, the MP 204 auto-
matically compensates for cable impedances.
9.2.6 Power input and energy consumption
Actual input power and motor energy consumption.
The energy consumption is an accumulated value
which cannot be reset.
The power is calculated like this:
9.2.7 Energy trip counter
Counter for measuring energy consumption. Can be
reset. See section 9.4.12.
