Wrn Bus Lx >V
WrnBus Lx <V
(where x=1,2,3)
Hist Bus voltage is out of limits given by Bus < and Bus > Voltage setpoint.
Bus >, <Frequency Hist
The bus frequency is out of limits given by Bus Right Overfrequency
(page 184) and Bus Right Underfrequency (page 184) setpoints.
Bus Voltage
Unbalance
Hist
The bus voltage is unbalanced more than the value of Bus Right
Voltage Unbalance (page 183).
Current Unbalance MP
The mains current is unbalanced more than the value of Current
Unbalance (page 188) setpoint.
Current IDMT MPR
Mains current exceeds the limit for IDMT protection given by Nominal
Current (page 175) and IDMT Overcurrent (page 187) setpoints.
Short Circuit MPR
Short circuit current alarm is activated when the current value is out of
limits given by Short Circuit BOR (page 186)
BTB Fail WRN Failure of mains circuit breaker.
Bus CCW Rot WRN
Bus voltage phases are not wired correctly. MGCB closing is
prohibited by controller.
Wrn
Synchronization Fail
WRN If the synchronization timeout gets elapsed (forward synchronization).
Bus Meas Error WRN Bus measurement error. Bus voltage is out of limits for 20s.
Note: This table does not contain all alarms in controller. It is only list of the most common alarms.
5.4.11 History log
The history log is an area in the controller’s non-volatile memory that records “snapshots” of the system at
moments when important events occur. The history log is important especially for diagnostics of failures and
problems. When the history file is full, the oldest records are removed.
Each record has the same structure and contains:
• The event which caused the record (e.g. “Overspeed alarm” or “GCB closed”)
• The date and time when it was recorded
• All important data values like RPM, kW, voltages, etc. from the moment that the event occurred.
