load (K2 Close)
，
will output unload signal (K2 Open)
；
if taken no load (K2 Open)
，
accumulator
will output load signal (K2 Close)
；
Two accumulators Priority: In Manual mode, only genset will be started and the ATS will not
act.
AUTO TRANSFER PROCEDURES:
1. If input port is configured as Close Generator Auxiliary
◆
If “Open breaker detect” is “SELECT Enable”
Generator load is transferred into generator un-load or accumulator load is transferred into
accumulator un-load or accumulator is full charged, after the open delay; switch off signal
will be output while “fail to transfer” delay will be initiated. Once the delay has expired, if
switch off failed, it will wait for switch off. Otherwise, switch off is completed.
Generator unload is transferred into generator load or accumulator unload is transferred
into accumulator load or accumulator charge is beginning, after the close delay, switch on
signal will be output while “fail to transfer” delay will be initiated. Once the delay has
expired, if switch on failed, it will wait for switch on. Otherwise, switch on is completed.
If “fail to transfer” warn is “Enable”, alarm signal will be initiated whatever switch on or off
failure.
◆
If “Open breaker detect” is “SELECT Disable”
Generator load is transferred into generator unload or accumulator load is transferred into
accumulator un-load or accumulator is full charged, after the open delay, switch off is
completed.
Generator unload is transferred into generator load or accumulator unload is transferred
into accumulator load or accumulator charge is beginning, after the close delay, switch on
signal will be output while “fail to transfer” delay will be initiated. Once the delay has
expired, if switch on failed, it will wait for switch on. Otherwise, switch on is completed.
If “fail to transfer” warn is “Enable”, alarm signal will be initiated f switch on failure.
2. If input port is
NOT
configured as Close Generator Auxiliary
Generator un-load is transferred into generator load, close generator output.
Generator load is transferred into generator un-load, open generator output.
