Events (Alarms And Messages); Alarms List - ABB MegaFlex UL S1 Series User Manual

6.3.1 Events (alarms and messages)

Each of the following listed events, alarm or message, can be displayed on the LCD screen, on a PC with the
software "Data Protection" installed or with the monitoring system "iUPSGuard".
Alarms and Messages are differently specified because the alarms are indicating an abnormal functioning of the
UPS (which are additionally signaled with the LED ALARM and acoustically with the buzzer), while the messages
indicate the various states of operation of the UPS (stored in the events list, but not activating the LED ALARM
and the acoustical alarm).

Description
Parameters are lost and have been replaced with default
values.
Please contact your ABB Service Center for intervention.
A blocked DSP on the Control board causes this alarm and
consequently the shut-down of Rectifier and Inverter and
the opening of K3.
The master unit detected the slave unit missing on the
communication bus even though "Q1 – External UPS Output
Circuit Breaker" is still closed.
The parallel communication bus system is subject to high
errors rate on channel JA.
The parallel communication bus system is subject to high
errors rate on channel JB.
There is an interruption in the channel JA of the parallel
communication bus system.
There is an interruption in the channel JB of the parallel
communication bus system.
The connectivity communication
interrupted.
The unit has detected an earth leakage current above a
configured threshold (typically 5% of the maximum rated
input current).
Applicable to 3-wire (3ph+PE) distribution only.
The unit has detected load ground current above a
configured threshold.
Applicable to 3-wire (3ph+PE) distribution only.
The Control Panel communication bus is faulty or
interrupted.
The u-switch mounted on the Rectifier input fuses indicates
a blown fuse and consequently it is shut down.
Clearance of this condition allows you to restart the
Rectifier.
K4 not closed despite a closing command being issued.
Signaled by auxiliary contact.
Rectifier cannot start.
K4 not open despite an opening command being issued.
Signaled by auxiliary contact.
Utility remains connected to Rectifier bridge.
This function, when enabled on input programmable relays
("Service Code" required), warns the user about the
external Battery Fuses failure or MCB opening, signaled by
NO free contact.
