WL Circuit Breaker

A01: Network frequency

A02: Average value of the phase-to- phase voltages

A03: Total active power

A04: Average value of the power factors

The scale for displaying the frequency must range from 45Hz to 65Hz. This enables the standard frequencies in countries where IEC and UL standards apply to be displayed.

Example: 45Hz = 0 V/4mA and 65Hz = 10V/20mA.

The scalings of the other measured values can be read in the appropriate switch positions.

Switch position "cos "

The following measured values are output in switch position "cos ":

A01: Power factor cos L1

A02: Power factor cos L2

A03: Power factor cos L3

A04: Phase unbalance - current (%)

The power factors are displayed from

The test mode is started by pressing the "TEST" key and indicated by the yellow DEVICE LED. Although the measured values continue to be updated in the test mode, they are not output at their respective channels.

•The test mode is started by pressing the "TEST" key.

•Pressing the "TEST" key again selects output 1, which is indicated by LED A01. The test signal is output. For currents, voltages, and power rating values, this is equivalent to the full-scale value, with cos 1 and with a frequency of 55Hz.

•Pressing the key again selects output 2, which is indicated by LED A02. This automatically deletes the value at output 1 and sets the value at output 2.

•By repeating the above steps, the output and scaling of all four outputs can be checked one after the other.

•Selecting output A04 and pressing the "TEST" key activates all four LEDs, but does not activate an output. Pressing the key again selects output 1 again.

•If the "TEST" key is not pressed within 30 seconds after an output has been selected, the system exits the test mode automatically and returns to the standard operating mode. The values, which are constantly updated in the background, are then updated at the outputs again.

0.7(leading) (= 0V/4mA) through 1 (= 5V/12mA) to 0.7 (lagging) (= 10 V/20mA). The phase unbalance of the three currents is displayed from 0% (0V/4mA) to 50% (10V/20mA).

Note: Ensure that the polarity is correct during connection.
