236 Check Synch. OK
If linked to an opto input in a dedicated PSL and
energised, it indicates that external synchronism
conditions are met – This can be linked afterwards to an
internal autoreclose logic
PSL (OUT)
Synchro
Check
237 V< Dead Line
Dead Line: high when the Dead Line condition is met
(voltage below the 'V< Dead Line' threshold value
(setting) – The measured voltage is always calculated as
a single phase voltage
PSL (OUT)
Synchro
Check
238 V> Live Line
Live Line: high when the Live line condition is met
(voltage above the 'V> Live Line' threshold value
(setting) - always calculated as a single phase voltage
reference.
PSL (OUT)
Synchro
Check
239 V< Dead Bus
Dead Bus: high when the Dead Bus condition is met
(voltage below the V<Dead Bus threshold value (setting)
- always calculated as a single phase voltage reference.
PSL (OUT)
Synchro
Check
240 V> Live Bus
Live Bus: high when the Live Bus condition is met
(voltage above the V>Live Bus threshold value (setting)
- always calculated as a single phase voltage reference.
