Comet installation and user manual: E-6761200XT/FA 7.3 Merlin Gerin by MGE UPS SYSTEMS
■ "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".
■ 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.
