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.
