Advanced Control Unit
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
using PLC (Programmable Logic
Controller)
The ACU is a hot pluggable unit optimal for use in both embedded or
stand-alone applications. It can provide remote monitoring,
configuration, status information and control of the Telecom site’s
overall function, voltages, currents, temperatures and related
alarms.
True hot plug installation of controller
unit - thanks to simplified
communication cable connection
installation to a separate connection
board
When used together with external supervision modules, the ACU
Quick failure analysis – owing to
storage of the 400 latest alarms
gensets, DC power plant, battery backup, smoke detectors, fans,
can present detailed information and alarms regarding the
condition and status of the Telecom site’s AC mains supply, diesel
doors, and site environment (temperatures, humidity) etc.
If maintenance and site visits, related to the Telecom site, are based

upon this information they can be optimized to save both time and
money, especially if the site is located remotely.
The information and alarms, from a specific site, can be monitored
or checked by means of a simple web browser or special monitoring software. When using a web browser no additional software is
needed, and the web browser login to monitor the site is password
protected.
The ACU is a control unit designed for global use, and it withstands
high telecom standards, and provides great reliability and availability.
