4.1 Alarms and Warnings

A warning or an alarm is signalled by the relevant LED on
the front of the frequency converter and indicated by a
4 4
code on the display.
A warning remains active until its cause is no longer
present. Under certain circumstances operation of the
motor may still be continued. Warning messages may be
critical, but are not necessarily so.
In the event of an alarm, the frequency converter has
tripped. Alarms must be reset to restart operation once
their cause has been rectified.
This may be done in four ways:
1. By pressing [Reset].
2. Via a digital input with the "Reset" function.
3. Via serial communication.
4. By resetting automatically using the [Auto Reset]
function, which is a default setting for TR200, see
14-20 Reset Mode.
NOTICE
After a manual reset pressing [Reset], press [Auto
On] or [Hand On] to restart the motor.

TR150 Programming Guide
If an alarm cannot be reset, the reason may be that its
cause has not been rectified, or the alarm is trip-locked,
see Table 4.1.
Alarms that are trip-locked offer additional protection,
means that the mains supply must be switched off before
the alarm can be reset. After being switched back on, the
frequency converter is no longer blocked and may be reset
as described above once the cause has been rectified.
Alarms that are not trip-locked can also be reset using the
automatic reset function in 14-20 Reset Mode
NOTICE
Automatic wake-up is possible!
Could result in equipment or property damage.
If a warning and alarm is marked against a code in the
table on the following page, this means that either a
warning occurs before an alarm, or it can be specified
whether it is a warning or an alarm that is to be displayed
for a given fault.
This is possible, for instance, in 1-90 Motor Thermal
Protection. After an alarm or trip, the motor carries on
coasting, and the alarm flash on the frequency converter.
Once the problem has been rectified, only the alarm
continues flashing.
