Field Description
Impedance
These fields set the flicker reference impedance values when using an iX
Series with programmable impedance. Values used may differ between
European and Japanese standards. The Japanese standard presently
requires the use of the reference impedance for both harmonics and flicker
tests. During harmonics tests, this will result in high voltage distortion. This
conflict has not been resolved at this time. The programmable impedance
values are different for single and three phase modes. This setting is only
relevant if you select " CI Source with programmable impedance" in the
System Configuration setting.
If the AMX power source is used, the output impedance may have to be set
to a value other than 0 using the Z (Ohms) field at the bottom of this section.
System
Configuration This setting determines if a reference impedance is used and if so, which
type. Available choices are:
No CI power
source Select this option if you are not using a CI AC Source or have no OMNI
impedance.
OMNI included
with PACS Select this option if you have a 1251RP-CTS system, a PACS-1RP or a
PACS-LR1
External OMNI
Select this option if you have a OMNI-1-18I / LR1, OMNI-1-37 / LR2, OMNI-
3-18I / LR3, OMNI-3-37I / LR4 or OMNI-1-37iJ / LR5.
CI Source with
programmable
impedance
Select this option if you have a standard iX Series CTS system with
programmable impedance.
AMX Source
Select this option if you have a PPS AMX power source model. Use of this
model requires that the programmable impedance values are set to match
any lumped impedance that may be part of the system or to the correct IEC
60725 reference impedance values. This may require on-site calibration.
The value must be set in the Z(Ohms) field of the Impedance section.
