Appendix A: Pulsar Controller
User Interface Overview
The Galaxy Pulsar Plus NE843 family of controllers monitor and control system components
including rectifiers, converters, and distribution modules via a multi-drop RS485 digital
communications bus. System status, parameters, settings, and alarm thresholds can be viewed and
configured from the controller’s front panel display. Assignment and configuration of alarm
inputs and output relays can be performed from a laptop computer connected to a local RS-232 or
Ethernet port, or by remote access is through a network connection to the World Wide Web
(internet) or your enterprise network (intranet). An optional modem is also available.
This section describes the controller features, functions and alarms from perspective of a user
utilizing the front panel display. All these features are available through the remote interfaces
including EasyView and Web pages served by the controller. EasyView is the Lineage Power
Systems GUI provided for local serial port or remote MODEM access. It supports all Lineage
controllers and has been around for many years and will not be discussed in detail. The web
interface and front panel will be the interfaces of choice. This section focuses on describing the
controller from the front panel perspective since it is the most available interface and requires no
PC or computer hardware. The items contained in the front panel are applicable to respective
feature implementations in the web pages.
Figure 5-1: NE843A/NE843C Front Panel Main Display
This display shows the front panel display for a system with both rectifiers and converters. The
display (V1 versus V2) correlates with test jacks. The large font indicates the “Primary” or
rectifier dc bus; the smaller font shows the “Secondary” or converter dc bus. The NE843 will
automatically determine the appropriate fonts and test jack designations.
For systems with no converters only a single voltage/current pair will be displayed on the front
panel along with the correct test jack association. The other test jack will be unused and will have
near zero voltage.
