Input, Output and LED Settings
Analog Inputs
These inputs can be configured by the User to represent the status of external analog values that are fed to the
relay.
Using Analog Inputs is a two step procedure. The user has to configure the
Measuring Elements
and the
Analog
Protection Elements
. Each Analog Input (hardware) is represented by one
Measuring Element
(named AnIn[x]).
That means the number of
Measuring Elements
is equal to the number of analog inputs. The user can set for each
Measuring Element
the type of input (e.g. 4...20 mA). The
Measuring Element
will provide analog values based on
this setting. The values being provided by the
Measuring Elements
have to be assigned onto the
Analog Protection
Elements
in order to feed them. Hence one
Measuring Element
can be assigned on multiple
Analog Protection
Elements
. The number and names of the
Analog Protection Elements
are depending on the ordered device.
Examples for
Analog Input Elements
.
Generator Protection Device (Example): FldC[n] - DC Field Current.
Motor Protection Device (Example): Spd[n] – Speed.
Transformer Protection Device (Example) TapV[n] - Tap Voltage.
Each
Analog Input Element
is available as an
Alarm
and as a
Trip
Element.
The Configuration comprises:
Step 1 (please see section “Setting the Measuring Elements”): The first step is to set within the [Device Parameters]
the type of input for each available Analog Input (Measuring Element). That means determining what kind of
measuring values will be provided by each analog input (e.g. 4...20 mA).
Step 2 (please see section “Configuring the Analog Protection Elements”): Configuring an Analog Protection
Element means: Activating the "Trip and/or Alarm-Element" within the [Device Planning]. After that, the Element has
to be configured within the [Protection Parameters].
