Configuring a Set Point Control via Analog Input
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The following example illustrates how to configure an easYgen for using an external load set point via analog in-
put [AI 03]. The external set point may be enabled using a switch, wired to discrete input [DI 04] (configure pa-
rameter 1262 “Alarm class” to control). An analog 0 to 20 mA input is to be used where 4 mA corresponds with
0 % power (0 MW), 12 mA corresponds with 50 % power (1 MW), and 20 mA corresponds with 100 % power
(2 MW).
Configuring the Rated Generator Power
From the main screen on the unit select Parameter -> Configuration -> Measurement config. and configure the
following parameter:
ID Parameter Value Comment
1752 Gen. rated active power [kW] 2000 Generator rated power of 2 MW

Configuring the Analog Input for Real Power Set Point
From the main screen on the unit select Parameter -> Configuration -> Application config. -> Inputs/outputs con-
fig. -> Analog inputs config.-> Analog input 3 and configure the following parameters:
ID Parameter Value Comment
1100 Type Linear A user-defined linear characteristic curve is to be used
1101 User defined min display value +00000 A value of 000.00 % is displayed at the minimum of the input range
1102 User defined min display value +10000 A value of 100.00 % is displayed at the maximum of the input range
1139 Sender value at display min. 020.00% The sender value at minimum display is 20 % i.e. 4 mA
1140 Sender value at display max. 100.00% The sender value at maximum display is 100 % i.e. 20 mA
1120 Sender type 0 - 20mA A 0 to 20 mA sender is used on the analog input
1103 Monitoring wire break Low If the analog signal falls below 2 mA, a wire break is indicated
1104 Wire break alarm class Class B An alarm of class B will be issued in case of a wire break
1105 Self acknowledge wire break No A wire break is not automatically cleared after it has been repaired
10116 Filter time constant Off No filter time constant is applied to the analog signal
3636 Bargraph minimum +00000 The start value for the bargraph display of the analog input is 00000
3637 Bargraph maximum +10000 The end value for the bargraph display of the analog input is 10000

The following parameters may only be changed using ToolKit and serve for a more detailed display of the analog
value:
ID Parameter Value Comment
1125 Description ActivePower SP (%) Analog input [AI 03] is labeled with "ActivePower SP (%)" on the display
1135 Value format 000.00% The value format of the bargraph display of the analog input is "000.00%"

Configuring the Load Controller
The load controller is to be configured that it uses a fixed load setpoint 1 of 2 MW unless a switch energizes dis-
crete input [DI 04] for enabling a variable load setpoint 2, which is controlled by analog input [AI 03].
From the main screen on the unit select Parameter -> Configuration -> Application config. -> Controller config. -
> Load control config. and configure the following parameters:
ID Parameter Value Comment
5539 Load setpoint 1 source 05.04 Internal pwr. setp.1 Internal power setpoint 1 is used as setpoint 1
5526 Load setpoint 1 Constant A constant load is to be controlled for setpoint 1
5520 Int. load control setpoint 1 02000.0kW A constant load of 2 MW is to be used for internal setpoint 1
5540 Load setpoint 2 source 06.03 Analog input 3 Analog input 3 is used as setpoint 2
5527 Load setpoint 2 Constant A constant load is to be controlled for setpoint 2
