PCS100 UPS-I User Manual 83
Parameter:
132 Surge Recording Thres
Function:
Power quality meter surge recording threshold
Access:
Operator
Range:
530 RMS Sag Threshold to 200%
Units:
% of parameter 121 Utility Voltage
Factory
Setting:
110%
Setting up:
This parameter adjusts the recording threshold for surge events recorded in the event log
and on the summary page. It does not alter the operation of the PCS100 UPS-I. Set the
same as or greater than parameter 531 RMS Surge Threshold. If set less than 531 RMS
Surge Threshold the PQ meter may record part of the pre event surge voltage and give an
erroneous reading.
Parameter:
141 V Droop Comp R
Function:
Compensation for voltage drop across the coupling transformer resistance
Access:
Tech
Range:
0.0 to 10.0
Units:
%, base = 121 Utility Voltage
Factory
Setting:
7
Note:
At full load the PCS100 UPS-I inverter output voltage will be increased by this amount to
compensate for the voltage drop across the coupling transformer resistance. The
compensation voltage will reduce linearly to zero at zero load.
Setting up:
Leave at factory setting.
Parameter:
142 V Droop Comp X
Function:
Compensation for voltage drop across the coupling transformer inductance.
Access:
Tech
Range:
0.0 to 10.0
Units:
%, base = 121 Utility Voltage

Setting:
4
Setting up:
Leave at factory setting.
