Parameter: Mode
•
Default setting (_:9661:1) Mode = off
With the Mode parameter, you activate the trigger for normal operation (On) or the test mode (Test).
Parameter Value
on
off
test
Parameter: Max. Trigger Active/Max. Trigger/Max. Trigger Hysteresis
•
Default setting (_:9661:101) Max. trigger active = yes
•
Default setting (_:9661:105) Max. trigger = 69.284 V
•
Default setting (_:9661:113) Max. trigger hysteresis = 0.980 p.u.
With the Max. trigger active parameter, you activate the level trigger in order to monitor the voltage in
the positive-sequence system and to prevent it from exceeding the set values.
Parameter Value
yes
no
The hysteresis is preset at the factory to 0.980 p.u. (equal to 2 %) of the parameter Max. trigger and can
be adjusted.
Parameter: Min. Trigger Active/Min. Trigger/Min Trigger Hysteresis
•
Default setting (_:9661:102) Min. trigger active = yes
•
Default setting (_:9661:106) Min. trigger = 46.189 V
•
Default setting (_:9661:114) Min. trigger hysteresis = 1.020 p.u.
With the Min. trigger active parameter, you activate the level trigger in order to monitor the voltage in
the positive-sequence system and to prevent ut from dropping below the set value.
Parameter Value
yes
no
The hysteresis is preset at the factory to 1.020 p.u. (equal to 2 %) of the parameter Min. trigger and can
be adjusted.
Parameter: dM/dt Rise Active - dM/dt Rise (/Filter Time) - dM/dt Rise Hysteresis - Filter Time
•
Default setting (_:9661:103) dM/dt rise active = no
•
Default setting (_:9661:107) dM/dt rise (/Filter time) = 11.547 V
•
Default setting (_:9661:115) dM/dt rise hysteresis = 0.980 p.u.
•
Default setting (_:9661:112) Filter time = 2 periods

Description
The function block V1 Trigger is activated and the voltage in the positive-
sequence system is monitored on the basis of the set trigger parameter.
The function block V1 Trigger is deactivated.
The function block V1 Trigger is activated for test purposes.
Description
The voltage in the positive-sequence system is monitored for overvoltage.
The voltage in the positive-sequence system is not monitored for over-
voltage.
Description
The voltage in the positive-sequence system is monitored for undervoltage.
The voltage in the positive-sequence system is not monitored for under-
voltage.
