8.5 RPV Input (-RPV)
The –RPV option is factory installed only. If installed, this option disables the internal controller voltage
programming reference. Instead, a user provided DC signal is used to drive all amplifiers. Note that
only one RPV input is available so in three phase modes, all three outputs will track the same RPV DC
input signal.
A 0 to 10 VDC signal will provide a 0 to full-scale voltage output on the selected voltage range.
To enable the RPV mode, press the MENU key until the CONTROL screen and scroll to the ALC
setting entry. If the ALC is set to REG or ON, turn if OFF first. Then scroll to the VOLT REF entry.
Select EXT to use the RPV (remote programming voltage).
The presence of the RPV option is indicated by the –PRV field in the model number on the serial tag.
Note that the –EXT and –RPV options are mutually exclusive so only one or the other can be present.
8.6 Ethernet Interface (-LAN)
The Ethernet interface is available as a factory installed option on the Compact iX Series models.
For details on operation of the Ethernet interface and programming command syntax, refer to the i/iX
Compact Series Programming manual, CI P/N 6005-961 provided in PDF format on CD ROM CIC496.
8.7 Clock and Lock (–LKM / -LKS)
The –LKM and –LKS options are available on the iX Series AC power source models. This option
allows one or more auxiliary unit outputs to be phase synchronized to a master iX unit.
Note: The output of any units that are locked together CANNOT
be paralleled to obtain more
current.
The Clock and Lock mode is provided for the creation of multi-phase systems.
For connection and operation information of the Clock and Lock mode, refer to section 3.9 of this user
manual.
