All of the information can be accessed through the LCD Display by using the 3 arrow keys on the front panel of the UPS.
The information is arranged in columns. The and keys allow movement up and down the selected column and the key moves from one column to the top row of the next column.
Para 5b = SOFTWARE DESCRIPTION ( FSB >= 30 )
5b.2.1 The first column contains information relevant to the UPS as a whole.
The first page will normally show the UPS rating on the first line with one of the following messages on the second:
SYSTEM NORMAL TESTING BATTERY TESTING AUTONOMY
E.P.O. ACTIVE NOT CALIBRATED SYSTEM TEST MODE
SYSTEM IN ALARM
If the battery is discharging or the inverter is in overload operation then an additional page of information is inserted at the top of the first column.
This will be in the form:
BATTERY DISCHARGING AUT **min DIS **min
or
OVERLOAD INV STOP **m:**s
If both conditions are true then both pages of information will be accessible.
The top of the column will be the one showing the shortest time before inverter shutdown.
If none of the arrow keys is pressed, then after 5 minutes the display will return to the top page of the first column of information.
This top page will automatically change according to the UPS operating condition as described above.
Para 5b = SOFTWARE DESCRIPTION ( FSB >= 30 )
Following the UPS status, each of the measurements available in the UPS can be displayed. These are:
D.C. Voltage and Rectifier Current D.C. Voltage and Battery Current Inverter Voltage and Frequency Reserve Voltage and Frequency Load Voltage and Frequency Load Currents
Load Percentage Loading Load Peak Factor
Total time on Inverter Total time on Reserve
Number of mains failures and Total Duration Total number of mains failures and Total Duration
Pressing the key moves down through this list. The key can be used to move back up.
At the end of the measurements, the software code, revision and release date is displayed.
Note that the revision and release date of the software is also displayed for 2 seconds when the machine is switched ON.
Para 5b = SOFTWARE DESCRIPTION ( FSB >= 30 )
5b.2.2 The second column contains information relevant to the Rectifier and Battery.
The first line of the display will show:
RECT/BATT ALARMS
While the second line will show the first active message from the following:
NO ALARM ACTIVE NOT CALIBRATED DC FEEDBACK FAULT VERIFY DC FEEDBACK PRIMARY SUPPLY FAIL PHASE SEQUENCE ERROR
BATTERY FAULT PCB SUPPLY FAULT BATT CONTACTOR OPEN BATTERY DISCHARGING SHUTDOWN IMMINENT
DC VOLTAGE HIGH DC VOLTAGE LOW INPUT SWITCH OPEN HARMONIC FILTER OPEN
RECTIFIER ALARM RECTIFIER INHIBITED
RECTIFIER BLOCKED BATT. CHARGE INHIBIT
If more than one of these alarms is ON, pressing the key will move through the list of active messages.
After the last active alarm, pressing the key will move through the following pages of measurements:
D.C. Voltage and Rectifier Current D.C. Voltage and Battery Current
Para 5b = SOFTWARE DESCRIPTION ( FSB >= 30 )
5b.2.3 The third column contains information relevant to the Inverter.
The first line of the display will show:
INVERTER ALARMS
While the second line will show the first active message from the following:
NO ALARM ACTIVE NOT CALIBRATED PCB SUPPLY FAULT
OUT OF SYNC DESATURATION OVER TEMPERATURE BYPASS SWITCH CLOSED
SHUTDOWN IMMINENT DC VOLTAGE HIGH
DC VOLTAGE LOW INVERTER NOT RUNNING
INVERTER INHIBITED INVERTER BLOCKED INVERTER VOLTS HIGH
INVERTER VOLTS LOW OVERLOAD
STOP DUE TO OVERLOAD CURRENT LIMIT
INVERTER STATIC SWITCH FAULT INVERTER FREQUENCY OUT OF RANGE 8%
INVERTER FEEDBACK FAULT VERIFYING INVERTER FREQUENCY
VERIFYING BATTERY CONTACTOR INVERTER FREQUENCY OUT OF RANGE 1%
If more than one of these alarms is ON, pressing the key will move through the list of active messages.
Para 5b = SOFTWARE DESCRIPTION ( FSB >= 30 )
After the last active alarm, pressing the key will move through the following pages of measurements:
Inverter Voltage and Frequency.
Inverter current
5b.2.4 The fourth column contains information relevant to the Load and Reserve.
The first line of the display will show:
LOAD/RES ALARMS
While the second line will show the first active message from the following:
NO ALARM ACTIVE NOT CALIBRATED LOAD ON RESERVE LOAD NOT SUPPLIED BYPASS SWITCH CLOSED
RESERVE SUPPLY FAULT RESERVE FREQ FAULT RESERVE VOLTS HIGH RESERVE VOLTS LOW
STATIC SWITCH BLOCKED ON INVERTER STATIC SWITCH BLOCKED ON RESERVE
INVERTER STATIC SWITCH FAULT OVERLOAD
OUTPUT SWITCH OPEN RESERVE SWITCH OPEN PHASE SEQUENCE FAULT
RESERVE INHIBITED
If more than one of these alarms is ON, pressing the key will move through the list of active messages.
Para 5b = SOFTWARE DESCRIPTION ( FSB >= 30 )
After the last active alarm, pressing the key will move through the following page of measurements:
Load Voltage and Frequency Load Current
Percentage Loading Load Peak Factor
Reserve Voltage and Frequency
5b.2.5 The fifth column is normally used to select the language for LCD messages.
Using the and keys changes the language and pressing the key returns to the first column with the messages displayed in the selected language.
Once a language has been selected, this will remain in use until it is changed using the language selection column.
If the UPS is switched OFF and then ON again it will power up in the selected language.
If POWER HISTORY information is available the pressing the key from the fourth column will cause the LCD to display:
POWER HISTORY DOWN TO ACCESS
Pressing the key will now enter into the Power History information.
When the Power History is exited, the display will return to this entry message.
Pressing the key from here will move on to the language selection column, and pressing again will return to the first column.
If no key is pressed for 5 minutes, the display changes back to the top row of the first column of information.

5b.3 Measurements
5b.3.1 D.C. voltage
One sample is taken every 100mSec and the displayed reading is filtered over 8 consecutive samples.
This reading is scaled related to the battery elements number as follow:
Elements Sense Input Displayed readings
144 2.215 V 326.0 V
198 2.215 V 449.5 V
240 2.215 V 544.8 V
