10.3.1. Messages

The type of light emitted by the alarm / fault lamp on the control compartment door depends
on the type of message:
– Flashing light: alarm
– Light remains on: fault
1 L -> 600.0 rpm
ACS5000

** FAULT **

CW1 NoWtrPumpOn
The message can be saved and viewed in the fault history of the drive when a PC with
DriveWindow, DriveDebug or DriveMonitor is connected to the drive. The fault history can also
be called up on the CDP control panel.

10.3.2. Error message levels

Two error message levels are used in the drive:
– Alarm: does not shut down the drive
Fault: shuts down the drive
–

10.3.2.1. Alarm

An alarm does not shut down the drive. If the condition causing the alarm is not corrected, a
persisting alarm can often lead to a fault. An alarm cannot be reset manually. The alarm
message is deleted from the display as soon as the alarm condition has been corrected.
10.3.2.2. Fault
A fault shuts down the drive. The type of shutdown depends on the origin of the fault.
Depending on the type of fault, the drive opens the main circuit breaker (MCB) or keeps it
closed:
– Class 1 faults (FC 1) open the MCB.
– Class 2 faults (FC 2) do not open the MCB.
Since the MCB is controlled and monitored entirely by the drive, no external opening command
must be given to the MCB when a fault condition occurs.
A fault condition must be corrected and the fault be manually reset before the drive can be
started again.
