CUSTOM COMBINATION OUTPUT
Defined combination output is composed by 3 parts, OR conditional output SW1, OR conditional
output SW2, AND conditional output SW3.
SW1 or SW2 is
TRUE
, while SW3 is
TRUE
, defined combination output is active;
SW1 and SW2 are
FALSE
, or SW3 is
FALSE
, defined combination output isdeactivated.
NOTE4:
SW1, SW2, SW3 can be set as any contents except for “defined combination output” in the output setting.
NOTE5:
3 parts of defined combination output (SW1, SW2, SW3) couldn’t include or recursively include themselves.
Example:
Contents of OR condition output SW1: output port 1 is active;
Close when OR condition output SW1 is active /inactive: close when active (disconnect when
inactive);
Contents of OR condition output SW2, output port 2 is active;
Close when OR condition output SW2 is active /inactive: close when active (disconnect when
inactive);
Contents of AND condition output SW3: output port 3 is active;
Close when AND condition output SW3 is active /inactive: close when active (disconnect when
inactive);
When input port 1 is active or input port 2 is active, if input port 3 is active, defined combination
output is outputting; If input port 3 is inactive, defined combination output is not outputting;
When input port 1 is inactive and port 2 is inactive, no matter port 3 is active or not, defined
combination output is not outputting.

DEFINITE TIME AND INVERSE DEFINITE TIME OF OVER CURRENT
Definite Time
：
overcurrent delay is definite time. Different overcurrent value has the same preset
delay.
Inverse Definite Time
：
overcurrent delay decreases as overcurrent increases. Different
overcurrent value has different corresponding delay.
Inverse overcurrent delay formula:
T = t / ((IA/IT)-1)
2
T
：
Overcurrent delay (second)
t
：
Timing multiplier ratio
IA
：
Current max. load current
（
L1/L2/L3
）
IT
：
Set overcurrent value
Example
：
t = 36
IA = 550A
IT =500A
Conclusion: T = 3600s(1hour)
