battery monitoring tests

■the battery is periodically checked every month. The message "17" on the diagnostics display 27 tells the user that the battery is in this operating mode;

■it is recommended to carry out a complete discharge test on the battery once a year in order to update the battery monitoring parameters. This test is activated by the "battery manual test" control. It calls for a minimum service charge. The message "18" on the diagnostics display 27 tells the user that the battery is in this operating mode.

In these operating modes, total battery failure is indicated by the alarm message "15" on the diagnostics display 27 .

overload (except for 5 kVA Comet S11 or S31)

■during a major temporary overload (greater than 1.5In):

■the load is supplied by AC input power via the "static bypass" 3 ,

■ return to the inverter 7 is automatic, following elimination of the overload;

■the inverter can handle a minor overload for a given duration depending on the size of the overload. See figure 21;

■when an overload occurs:

■the buzzer 17 sounds,

■the orange "fault" light 19 goes on,

■ the inverter 7 shuts down at the end of its corresponding overload time,

■the load is supplied by AC input power via the "static bypass" 3 ,

■the green "load protected" light 21 goes off,

■the red "load not protected" light 18 goes on.

If the overload continues during operation via the "static bypass" 3 , the supply of power to the load is interrupted after a specified time. See figure 22.

When Comet has shutdown due to an overload, the fault reset button must be pressed prior to return to normal operation.
