Mains connected
The mains connection status (logical condition) is active if following conditions are
matched
• Phase angle between Mains and Busbar is less than the configured limit (with delay •
time)
• Frequency difference between Mains and Busbar is less that the configured limit •
(with delay time)
This information is available as a LM command flag and can be used for changing the
operation modes from the mobile systems. 04.78 MS mains connected

Description
8931 Phase angle
difference 2 1 to 20°
[5°]
If the actual phase angle
difference between mains
and busbar is less than the
configured limit the phase
angle condition is met.
8932 Frequency
difference 2 0.01 to 0.20Hz
[0.05Hz]
If the actual frequency
difference between mains
and busbar is less than the
configured limit the
frequency condition is met.
8933 Delay mains
connected 2 1 to 30s
[5s]
The configured delay time
for "Mains connected"
starts if the phase angle
and frequency condition
are met.
Mains disconnected
The mains disconnection status (logical condition) is active if following conditions are
matched
• Generator frequency change is greater than the configured limit •
• Mobile Systems "MCB is closed" condition •
• GCB is closed (with 2s add on delay) •
This conditions is latched and resets either if no Mobile System LogicManagers are active
or with the rising edge from the mains connection status.
