■"32" - phase shift outside tolerance range: this display indicates that the

phase between the Mains 2 power supply of the "static bypass" 3 and the "inverter module" 7 is outside the tolerance range;

■"33" - phase sequence fault: informs the user that the phase sequence of the three-phase power supply is incorrect;

■ "34" - frequency of Mains 2 power supply to "static bypass" 3 outside tolerances: the output inverter voltage is no more synchronised with Mains 2. load transfers may be carried out using the following procedure: press, for 3 seconds, simultaneously the security button 26 and:

■ the green "inverter on" button 22 to force transfer of the load to the inverter

7. Transfer results in a 0.5 second break in the supply of power to the load,

■ the grey "inverter off" button 23 to force transfer of the load to the "static bypass" 3 . Transfer results in a 0.5 second break in the supply of power to the load;

■"35" - "static bypass" overload: indicates an overload when the load is being supplied via the "static bypass". Reduce the load;

■"37" - Mains 1 voltage outside tolerance range: this display indicates that

the voltage of the Mains 1 power supply of the "rectifier module" 2 is outside the tolerance range;

■"39" - installation fault: indicates an incorrect connection at the frequency converter input; check the connection of the Mains 1 input source to terminal block XR1;

■"41" - load supplied via "static bypass" 3 (normal condition for certain configurations): this display indicates that the load is powered by the Mains 2 via the "static bypass" 3 ;

■ "51" - charger fault: indicates a fault in the charger module 6 ; contact the after-sales support department;

■ "61" - rectifier or chopper fault: indicates a fault in the rectifier module 2 ; contact the after-sales support department;

■"62" - chopper overtemperature: see fault "22";

■"63" - fuses blown on Mains 1 input: indicates that one or more fuses have blown in the rectifier module 2 ; contact the after-sales support department;

■"65" - chopper overload: indicates that the active power consumed is too high. Reduce the load;

■"71" - internal communication fault: indicates a Comet internal fault; contact the after-sales support department;

■"72" - internal communication self-test fault: see fault "71";

■"73" - CPU board self-test fault: see fault "71".

manual bypass

■if the load is no longer supplied, a manual bypass operation enabling supply is possible, while waiting for the after-sales support personnel;

■proceed as follows:

■turn off the input power switch 1 ,

■switch the battery circuit breaker 4 to "off" position,

■check that all lights are off,

■ turn the "manual bypass" switch 8 as indicated in figure 24 from the "NORMAL" position to the "BYPASS" position.
