PRODUCT DESCRIPTION
Before handling the control, read page ii, "Electrostatic Discharge Awareness". Be careful when unpacking the electronic control. Check the control for signs of
damage such as bent or dented panels, scratches, and loose or broken parts. Notify the shipper of any damage.
Benefits:
Monitoring of the Differential Current
The monitoring of the differential current is carried out in two stages..
The first monitoring level serves as a warning and can be enabled or disabled. Should the adjustable warning
characteristic be exceeded, a text appears in the display and a relay contact is enabled. The pick-up time and the
dropout delay of the relay output are adjustable. The warning stage of the monitoring is auto-resetting.
The second stage of monitoring (main stage) serves to initiate tripping. In contrast to the first stage, it offers the
possibility to monitor the overstepping of an adjustable tripping characteristic (Id < In) and additionally, a fixed
tripping-threshold of 100%, relative to the generator rated current (Id > In). The trigger-delay for each limit value
may be independently adjusted, thus allowing a shorter triggering time at higher differential currents. When one
or both tripping characteristics are exceeded, a text display is initiated and two relay contacts are energized. The
tripping characteristics possess a 2% hysterisis relative to the generator rated current. .
The signal relay is only automatically reset if the function "automatic reset relay" in the Entry field on the screen
is configured to "on". Otherwise, the resetting is carried out by pressing the "Clear" button on the front of the
unit or via the discrete input terminal 18 "reset".
The two monitoring levels can also be used to change the characteristics of the control function (stage 1: small
value and a long time; stage 2: high value and a short time)
Tripping Characteristic
The following figure shows the tripping and warning characteristics (with sample values for X12, Y1,and Y2). It
represents the tripping and warning thresholds (Y) relative to the restraint current (X) The positions of the corner
points are determined by the coordinates P (X12/Y2) and P (X12/Y1). The selection of these positions is dependent on the generator being protected. The following gives the ranges of tripping and warning thresholds:
IS / IN 0 to X12 The threshold Id is independent of the restraint current..
IS / IN X12 to 5 × IN The threshold Id is dependent on the restraint current. A change of 100% in the
restraint current causes an increase of 10% in the tripping threshold.
IS / IN > 5 × IN The threshold Id stays constant at 85%.
Different characteristics can be chosen for the first and second monitoring levels, whereby the horizontal position
(X-coordinate) is valid for both stages. The vertical position (Y-coordinate) can be chosen separately for each
monitoring level. This results in a fixed difference in thresholds of the first and second monitioring levels for
each restraint current Is
