10.8 Meter Menu
The following 11 functions are available through the Meter Menu.
Input Voltage, Output Voltage, Output Current, Output VA, Battery Voltage,
Battery Current, Battery Power, Temperature, System Days, Inverter Minutes
and Inverter Events. Output Voltages and Currents are True-RMS
measurements while Battery measurements use an Averaging technique.
The Measurements are updated on the MMI screen approximately every half
second and are of high resolution and near instrument quality. All system
parameters are calibrated from the factory and are done so at full scale.
10.9 Alarm Menu
If alarms are present, the active alarms will be displayed in the Alarm
Menu. If no alarms are active, the display will read Alarms (0). There are
many alarms that the system can diagnose. Some alarms are fixed and some
are programmable through the User Menu.
Fixed alarms are not user adjustable nor can they be turned on or off –
they are always active and are imperative for proper safeguarding and
operation of the system. The factory has broken down these alarms into
three modes of operation which are Startup, Charger and Inverter modes.
The possible fixed alarms are Startup Alarms
(Communication, Setup Conflict, Battery Voltage, Back-Feed, Transfer /AC
Fuse, Overload, Miswire, Incorrect AC), Charger Alarms (Communication,
Over-Temperature, DC Fuse, No Charge, Overcharge, Back-Feed, AC Fuse/
Wiring, Program Reference), Inverter Alarms (Communication, Over-
Temperature, Overload, Crest Factor, V-Out, Back-Feed, Low Battery,
Program Reference), Phase Rotation, CB Trip, UPS Bypass, Overload, and
Overload Shutdown.
User programmable alarms include Low Battery, Near Low Battery, High
Temperature, Utility Failure, Low VAC, High VAC and Load Reduction. These
can be turned on and off and adjusted through the User Menu.
The system is provided with an Inrush alarm to detect high inrush current
associated with modern lighting loads. This feature is factory adjustable and
if this alarm occurs, please consult factory for troubleshooting the connected
load.
Further explanation of Alarms and possible causes shall be explained
throughout this document.
10.10 Event Log
An Event is when the System transfers from Battery Charging mode (99.9%
of life) over to Emergency Power and starts to discharge the battery. This
occurs when a system test is initiated or when a power outage occurs. During
an Event, the system keeps a record of critical parameters such as Time and
Date of the event, Output Voltage, Current, VA, Battery Voltage, Battery
Current and Battery Power. Since the system is constantly measuring these
parameters, it stores the Beginning of the Event and the End of the Event and
saves this information in a file. Up to 100 Events can be stored before
memory will start to overwrite the oldest event so the process is First In –
First Out and event #1 will always be the newest.
