ABB RER670 - Permissive Overreaching Scheme

13.1.3.3 Permissive overreaching scheme
M13869-34 v4
Set Operation = On
Set Scheme type = Permissive OR
Set tCoord = 0 ms
Set
tSendMin = 0.1 s (0 s in parallel line applications)
Set
Unblock = Off
Set tSecurity = 0.035 s
13.1.3.4 Unblocking scheme
M13869-43 v4
Set
Unblock = Restart
(Loss of guard signal will give both trip and alarm
Choose NoRestart if only trip is required)
Set
tSecurity = 0.035 s
13.1.3.5 Intertrip scheme
M13869-62 v5
Set
Operation = On
Set SchemeType = Intertrip
Set tCoord = 50 ms (10 ms + maximal transmission time)
Set
tSendMin = 0.1 s (0 s in parallel line applications)
Set
Unblock = Off
Set tSecurity = 0.015 s
