Serial Load Share Mode
Serial load share mode enables the controller to actively manage sharing load between all attached
serial rectifiers and to use the configured plant voltage set
-
point to regulate serial rectifier output
voltage.
•
Serial rectifiers are managed to load share among themselves
•
Serial rectifiers are managed to regulate plant voltage to the configured plant voltage set point.
Note
Load share within the group of non
-
serial rectifiers is not managed by the controller.
Note
Plant voltage is determined by non
-
serial rectifier voltage, configured plant voltage set point,
and various performance characteristics of the serial and non
-
serial rectifiers.
Note
Rectifier current sharing between the serial and non
-
serial groups of rectifiers may be very poor
and may change with load and with changes in ON rectifier capacity in the two groups.
None Load Share Mode
None load share mode disables the load share between serial rectifiers attached to the system.
•
Serial rectifiers are not managed to load share
•
Serial rectifiers are managed to regulate plant voltage to the configured plant voltage set point.
Configuring Load Share Mode
Load share mode may be configured via EasyView, Gateway web pages, or on front panel at

Network Access
-
LAN (Gateway)
Local and remote network access is provided in three DHCP modes: Client, Static, and Server.
CAUTION
Do not operate in DHCP Server mode when connected to a network. Severe network
problems may result.
DHCP Mode
-
Dynamic Host Configuration Protocol
Client Mode
Controller network parameters are dynamic. They are provided and managed by
DHCP server (manager) external to the controller. The controller IP address may be
different each time the controller connects to the network.
Static Mode
Controller network parameters are manually configured and static (unchanging).
Server Mode
Controller acts as the DHCP server, providing IP addresses to other devices on the
network.
Server mode is suitable only for connection to a local PC.
This mode is not compatible with networks with other DHCP servers attached.
