Screen 4.21: In a system with parallel configuration, this
•
alarm is displayed in one of the equipments (or some) that
detect communication errors, due to several reasons (par-
allel communication cables are disconnected, or wrong con-
nected, or in bad status; wrong configuration of any of the
equipments; etc.). Therefore, one of the equipments is set as
a fix Master of the system, and the rest of the equipments
can only be slaves permanently (or till the equipments are
shutdown and try to started them up again).
Screen 4.22: In a parallel system, with N+M configuration,
•
where:
N: nr equipments to size the system according to the max-
ˆ
imum permissible load.
M: nr redundant equipments in the system. It is equivalent
ˆ
to over sizing the equipments in the system, in order to
continue supplying the maximum permissible load without
overloading it. Usually, this value is fixed to "1".
The alarm is displayed when the load exceeds the maximum
permissible load by N equipments. In this condition, the equip-
ments will not be overloaded individually, meanwhile the load
doesn't exceed the maximum load of N+M equipments.
Example: Assuming that a parallel system of 2+1 equipments
of 20kVA (N=2, M=1).
If the load of the system is lower than 40kVA. Any over-
ˆ
load alarm is displayed in the system (if it is not exceeded
the individual overload per phase of each equipment).
If the load of the system is higher than 40kVA. The de-
ˆ
scribed alarm 4.22 of Lost of Redundancy is displayed.
If the load of the system is higher than 60kVA. Besides
ˆ
of the alarm 4.22 of Lost of Redundancy, there will also
be, as minimum, (among others), the alarm 4.2 of Inverter
overload in all the equipments of the system.
Screen 4.23: This alarm is displayed when in any phase, the
•
rectifier input voltage phase to neutral is out of the set range (+15
% / –20 % by default) or the rectifier input frequency is out of the
set range (± 5 Hz by default). Next, the rectifier is shutdown.
Screen 4.24: This alarm is displayed when the quantity of
•
IGBT desaturations in the rectifier stage, reaches its limit.
Screen 4.25: This alarm is displayed when there is a (*)
•
DSP Internal Error in the rectifier module, shutting down the
rectifier immediately. There will be 3 more retries before
blocking rectifier.
Screen 4.26: When a wrong phase rotation is detected in
•
the mains and under these conditions the rectifier is tried
to be turned ON, an input phase rotation alarm is displayed
shutting down the rectifier immediately.
Screen 4.27: When a high or low DC bus voltage of the equip-
•
ment is detected, the rectifier is shutdown for a while, in order
to retry to start up later on (see description of screen 4.51 too).
Screen 4.28: In a parallel system, rectifiers from the equip-
•
ments of the system connected in parallel can be shutdown,
due to the management of system as a whole, therefore this
alarm is displayed.
