2.1 General
•
for line section 1, addresses 6006 (km) or 6007 (Miles)
•
for line section 2, addresses 6016 (km) or 6017 (Miles)
•
for line section 3, addresses 6026 (km) or 6027 (Miles)
The length set for the entire line must correspond to the sum of lengths configured for the line sections. A
deviation of 10% max. is admissible.
Recognition of Running Condition (only for Motors)
When the configured current value at Address 1107 I MOTOR START is exceeded, this will be interpreted as
motor starting. This parameter is used by the start-up time monitoring and overload protection functions.
For this setting the following should be considered:
•
A setting must be selected that is lower than the actual motor start-up current under all load and voltage
conditions.
•
During motor start-up the thermal replica of the overload protection is "frozen", i.e. kept at a constant
level. This threshold should not be set unnecessarily low since it limits the operating range of the over-
load protection for high currents during operation.
Inverting Power Measured Values/Metered Values
The directional values (power, power factor, work and related min., max., mean and setpoint values), calcu-
lated in the operational measured values, are usually defined a positive in the direction of the protected
object. This requires that the connection polarity for the entire device was configured accordingly in the
P.System Data 1 (compare also "Polarity of the Current Transformers", address 201). But it is also possible
to make different settings for the "forward" direction" for the protection functions and the positive direction
for the power etc., e.g. to have the active power supply (from the line to the busbar) displayed positively. To
do so, set address 1108 P,Q sign to reversed. If the setting is not reversed (default), the positive
direction for the power etc. corresponds to the "forward" direction for the protection functions. Section
