The Load shed current has two timers the first one of which to expire will activate the Load shed
relay output.
The timers begin counting at different current levels and continue to count as long as current stays
above the set point. If it any point the current drops below the measuring point the timer will reset.
The first t1 begins counting as current rises above 120% of Max current. t2 begins counting when
current rises above100% of Max current.
The counter times are set to default vlaues. These can be changed by the following method.
Step 1.
From the ‘AC Current Calibration’ select ‘t1 120% and/or t2 100%’.
Step 2.
Use the soft keyboard to enter new timer value.
Step 3.
When both the timers have been set you are able to ‘Enable Load Shed’ at the ‘Load shed’
function.
