UPS systems must be easily manageable during normal operation and when fault conditions arise. It should be possible to effect control, and obtain management and alarm information both locally and remotely. There should be adequate arrangements for handling multiple modules within a UPS system, and multiple UPS systems across a site or business enterprise.
What you can manage from a UPS front panel
-
Operators can communicate locally with PowerWAVE® UPS-systems via their front mounted Power Management Displays (PMDs)
-
In a parallel redundant system, the PMDs have the same redundancy as the UPS modules, while control and monitoring of all the UPS modules can be effected from any single PMD

Each PMD comprises a Mimic Diagram, Control Keys and an LCD Display. The Mimic Diagram shows power flow status so that events such as mains failure or transfer to bypass can be seen at a glance. A dedicated LED and audible alarm indicate the detection of any internal or external fault condition. The menu driven LCD Display allows access to the internal Event Register as well as Autonomy Time and other measurements. Commands such as start-up, shut-down and transfer to bypass can also be executed using the Control Keys. A Diagnosis or Service mode is also available for adjustments and testing by trained personnel.
How to manage the UPS remotely
-
PowerWAVE® systems support a number of channels and options for remote communications and control
-
15 dry ports are available to accept inputs such as remote shut-down or generator interlock and outputs such as Mains Failure or Battery Low signals
-
Serial and network communications can be channelled through Modem/Ethernet, Modem/GSM or SNMP (Simple Network Management Protocol) ports
-
Information can be exchanged with other devices on the operator's network, or to remote or centralised locations via Internet or direct telephone links
