4. When the number of working module preset in the system more than the number of module entered in the Menu then there is an alarm of “FR/FC CONFIG ERR”. This alarm will disappear only when correct number of working modules entered in Menu.

5. Due to any reason, if module is failed and on module, there is an alarm of “FR/FC FAIL” then there is an alarm of “FR/FC XX FAIL” on system (XX stands for number of module).

6. Due to any reason, if module is not communicating with system or switching OFF any module, creates an alarm of “FR/FC XX NOT PRE” (XX stands for number of module). If the module is identified then it will show the respective number or it will show “FR/FC ?? NOT PRE”. If the module number is unknown, check number of FR/FC entered in menu.

7. To disconnect the battery from the system, select 000AH capacity for each battery. As soon as user selects 000AH, the DC contactor of the respective battery turns OFF. There is an interlock in the system that at least one battery will always be connected to the system. When user goes for selection of 000AH capacity of the last battery connected to the power plant as soon as he acknowledges it with “ENTER” key there is a massage “ONLY ONE BATT!!”. This last command is not accepted by the system, the previous AH capacity remains unchanged and also the respective DC contactor does not turns OFF.

8. When Mains AC voltage is more than the Mains high cut OFF voltage set in the menu then there is an alarm of “MAINS HIGH”. During the alarm the mains supply of the modules are isolated due to which modules are in OFF condition. When Mains AC voltage restores back with in the specified limit (Hysterisis of 10V is given to operate and release levels) there is a delay of 10sec(approx) to turn ON the modules.

9. When Mains AC voltage is less than the Mains low cut OFF voltage set in the menu then there is an alarm of “MAINS LOW”. During the alarm the mains supply of the modules are isolated due to which modules are in OFF condition. When Mains AC voltage restores back with in the specified limit (Hysterisis of 10V is given operate and release levels) there is a delay of 10sec (approx) to turn ON the modules.

10. If some how the system voltage increases beyond the LOAD VOLT HI value then there is an alarm of “LOAD VOLT HIGH”. This alarm is PRE WARN alarm for battery disconnection.

11. If Mains AC voltage is out of specified limit then the system works on battery and battery starts discharging. When the battery voltage reaches below the LOAD VOLT LOW value set in the menu then there is an alarm of “LOAD VOLT LOW”. This alarm is PRE WARN indication before battery disconnection voltage.

12. When battery is discharged below LOAD VOLT LOW condition and when the battery voltage reaches below the BAT DISCONNECT V value set in the menu then there is an alarm of “BATT DISCONNECT”. This alarm disconnects all the batteries (through DC contactors) connected to the system. Now battery will reconnect only when the system voltage rises above the BAT RECONNECT V set in Menu.

13. The system is having facility to monitor Battery room temperature. The system corrects the DC voltage in 72mV per degree centigrade law. At 27°C there is no correction but as temperature increases system voltage decreases and wise versa. 55.8V is the lock where further decrease in temperature will not cause any correction. Menu contains Settable range for lock in lower side where there is decrease in temperature. When the sensor is short or is open then there is an alarm of “TEMP. X COMP. FAIL” (X stands for battery number i.e. 1 or 2 or 3).

NOTE: The system has provision to monitor temperature of each battery with separate probes. When any of the sensors is open or short creates, an Alarm. Among all three temperatures, correction in system voltage is made according to highest temperature.

14. When programming 000AH isolates battery then the respective battery gets isolated and an alarm of “BATT X ISOLATED” (X stands for battery number i.e. 1 or 2 or 3) generated.

15. If any battery does not connected to battery terminal and user has selected other than 000AH for same battery then there is an alarm of “BATTERY X ABSENT” (X stands for battery number i.e. 1 or 2 or 3).

NOTE: Whenever any of the above alarm operates there is an audible as well as visual alarm. Buzzer is used as audio alarm whereas alarm is visualized on LCD display. To cut OFF audio alarm press alarm reset key. Whenever audio alarm is cut OFF visual alarm remains continuously until the alarm is rectified.
