For most of the types of faults defined here, the options
available are as hereunder:
0=Disable
1=Indicate (Display a Fault Message & or store in Flash)
2=Off Step (Switch off Non Fixed Steps one by one)
3=Off Fixed Step Also (Switch off All Steps one by one)
4=Fast Off Step (Switch off all Steps in one shot)
For all the faults, normally two limits are defined. One is
Detection Limit and another Resume Limit. Detection
Limit if exceeded by the parameter would mean the action
as defined by parameter in type of fault (as given here-
above). Resume Limit defines the parameter value below
which the fault is deactivated.
• Over Voltage: As name suggests, its for Over-Voltage
conditions.
• Under Voltage: For Under-Voltage conditions.
• Over Load: If APFC-05 detects the supply system is
overloaded, then it is sometimes recommended to remove
the capacitors out of circuit to reduce the fault current
levels. Under such circumstances this parameter is set.
Alternately, it can be set to Indicative.
• Under Load fault: The values here are set as % of
Maximum rated KW. This is useful in case of banks are
put in circuit to take care of no load compensation. Value
for this Under-Load KW can be calculated as shown here.
