Standard Control Unit (SCU) Controller, SCU M501D Features and Benefits Minimized installation time-as a result of easily configurable file upload/download High quality failure information-due to intelligent alarm setup through 1 using PLC True hot plug installation of controller unit-thanks to simplified communication cable connection installation to a separate connection board Quick failure analysis-owing to storage of the 200 latest alarms Extend battery life-for advanced battery management 1 2 PLC = Programmable Logic Controller ACU = Advanced Control Unit DC Power for TM Business-Critical Continuity Introduction The Standard Control Unit (SCU) provides detailed information and alarms regarding the condition and status of the telecom site's power plant. If maintenance and site visits related to the power plant are based upon this information, they can be optimized to save both time and money, especially if the site is located remotely. The SCU is a hot pluggable unit optimal for use in both embedded or stand-alone applications. It provides remote monitoring, configuration, status information and control of the DC power plant's voltage, current and alarm levels. Designed for global use, the SCU withstands high telecom standards, and provides great reliability and availability. In order to obtain detailed and extensive monitoring and control of auxiliary 2 equipment on site, the power plant can be upgraded from a SCU to a ACU by means of a simple swap of the hot pluggable SCU and ACU units.
