Pos.: Position of the terminal in the Bus Terminal block.

Type: Terminal type

Firmware: Firmware version installed on the terminal.

User scaling active (R32.0)

You can activate user scaling here (default: deactivated).

Watchdog timer active (R32.2)

You can deactivate the watchdog timer here (the default is activated).

DC filter active (R32.4)

Here you can disable the DC filter (default: enabled).

CosPhi, signed (R32.5)

Here you can disable the signed representation for CosPhi (default: enabled).

Energy measurement inverted (R32.6)

Here you can enable sign inversion for the energy measurement (default: disabled).

Flexible process image active (R32.3)

Here you can enable/disable the flexible process image (default:

• disabled for KL3403-0000, KL3403-0010, KL3403-0025, KL3403-0026, KL3403-0333,
• enabled for KL3403-0020, KL3403-0022)

Automatically clear minimum and maximum values (R32.7)

Here you can enable automatic deletion of the minimum and maximum current, voltage and power values (default: disabled).

Energy consumption scaling (R35)

Here you can change the scaling of the energy consumption measurement. Default: 4_dec (KL3403-0000 /-002x /-0333: 0,01 kWh, KL3403-0010: 0,05 kWh).

Minimum input voltage - undervoltage threshold (R36)

Here you can change the undervoltage threshold (resolution: 0.1 V).
If the mains voltage falls below the specified undervoltage threshold (default: 10 V), the red error LED is triggered, and the error bit (SB1.6) is set in status byte 0.

Current transformer ratio (R37)

The KL3403 can take the transformer ratio of a connected current transformer into account for the measured value output.
Here you can select the transformer ratio of a connected current transformer and enable this scaling with the option field User scaling (R32.0).

Note the permissible range of the measured value output The KL3403 should only take the transformer ratio into account if the calculated resulting current does not exceed the value 65535! If the calculated result does exceed 65535, the transformer ratio should be taken into account in the PLC.

Measuring cycle time (R39)

Here you can change the measuring cycle time (resolution: 1 ms) (default: 200 ms).

deletion time (R38)

Here you can change the time constant (resolution: 10 ms) for automatic deletion of the minimum and maximum current, voltage and power values (default: 2000 ms).

Password

Here you change can the password for the KL3403 (default: 4661_dec), in order to prevent unauthorized deletion of the energy consumption:

• Enter the old password in the field at the top.
• Enter the new password in the field in the center.
• Repeat the new password in the field at the bottom and click Change password

Password In this dialog box, you have to enter the passwords in decimal form! You can also use the password change register (R5) to change the password.

Energy consumption

Here you can clear the stored energy consumption. Enter the password and click Delete.

Deleting the energy consumption Once the energy consumption has been deleted, the value cannot be restored!
