Operation / Product description PCS 2
8.1 General - Product description PCS 2
PCS 2 - Power One Control System is a supervisory system particularly designed for supervision of power
supply systems based up on Power One rectifier modules. The design is based up on the philosophy that
one main controller supervises the entire power supply system, and use of distributed intelligence by local
micro controllers. A RS485 data bus is used for internal communication between the various units. Very
simple internal colour labelled signal wiring using only two cables with RJ45 plugs in each end. RS232
serial interface for remote control from a PC with PowCom
1
software.
For more detailed project specific information regarding system settings see Appendix B, Configuration.
This document specifies all available standard Power-One alarms, i.e. alarm 0 up to 23 and any customer
specific alarms (available as alarm 24 up to 39).
Note! Some of the alarms have Power-One standard limits and some of them have customer specific
adjusted limits.
A complete supervisory system do always consist of the following units:
PCS 2 - Main Controller
Master unit in the system communicating with all distributed micro controllers. Has an LCD display, menu
driven operation, visual alarm indication, RS232 contact for remote operation and RS 485 for internal
communication with 128 addresses (64 rectifier modules - and 64 other remote micro controllers).
Sockets for plug-in network interface. The Power-One Network Interface (PNI) is an optional component,
that allows the PCS unit to be remotely accessed via Ethernet and SNMP. The SNMP protocol allows
enhanced managing capabilities and enables the system to be accessed from any location. The protocol
uses simple commands to configure and control the system and relay the system status to the operator.
Using this monitoring ability allows the alarm messages to be transmitted to any location. The PNI also can
be used in conjunction with PowCom
TM
software either through a modem or Ethernet connection.
PCS 2 - Alarm Interface board
The alarm interface board contains:
z
Input for current reading
z
Battery and load breaker monitoring
z
Battery temperature and battery symmetry measurement
z
Output for operating two individual contactors (LVD and PLD)
z
6 potential free alarm contacts.
z
Three analogue and two digital inputs for supervision of miscellaneous signals (ventilation, door
open or other).

Power consumption:Max 30W
/- 12V
1. PowCom is a communications software package that allows the remote control of the system. The software uses a Windows
based interface to allow access to the PCS. PowCom is installed on a remote PC and can access the system by either direct
connection, a LAN, or through a dial-up modem.
