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 5a = SOFTWARE DESCRIPTION ( FSB < 30 )
5a.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 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:
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.
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 Currents
Load Peak Factor and Percentage Loading Total time on Inverter
Total time on Reserve
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 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 or if the retrofit option has been selected.

5a.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 PRIMARY SUPPLY FAIL PHASE FREQUENCY ERROR
BATTERY FAULT BATT CONTACTOR OPEN BATTERY DISCHARGING SHUTDOWN IMMINENT
DC VOLTAGE HIGH DC VOLTAGE LOW HARMONIC FILTER OPEN
BATT. CHARGE INHIBIT MAINS INPUT SWITCH OPEN
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

5a.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 INVERTER FAULT
OUT OF SYNC 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 STATIC SWITCH FAULT
CURRENT LIMIT SYSTEM TEST MODE
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 display Inverter Voltage and Frequency.

5a.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 LOAD ON RESERVE LOAD NOT SUPPLIED
INVERTER FAULT BYPASS SWITCH CLOSED
RESERVE SUPPLY FAULT RESERVE FREQ FAULT RESERVE VOLTS HIGH RESERVE VOLTS LOW STATIC SWITCH FAULT
OVERLOAD
PHASE SEQUENCE FAULT BACKFEED PROT ACTIVE OUTPUT SWITCH OPEN RESERVE SWITCH OPEN
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:
Load Current
Load Peak Factor and Percentage Loading Reserve Voltage and Frequency

5a.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.

5a.3 Measurements
5a.3.1 D.C. voltage
One sample is taken every 100mSec and the displayed reading is filtered over 10 consecutive samples. This reading is scaled so that an input signal of 2.215V will give a display reading of 326V.
