Liebert AC8
TM
The Liebert AC8 coordinates
control of systems with redundant
equipment, such as multiple
thermal-management units or
pumps. The AC8 can control
stand-by functions and unit
rotation, perform testing on
stand-by devices, stage operation
based on sensor-reading levels,
and monitor alarm status of
connected devices. The Liebert
AC8 interfaces with any device
that closes an electrical contact.
The AC8 tracks data in alarm,
event, and trend logs. System
configuration and data monitoring
is accessible using a local, LCD
interface and a remote dial-up
interface. The AC8 also interfaces
