Troubleshooting
Table 21: Possible faults
LED/fault pattern
Cause
Measures
Green LED does not light
up
No voltage or voltage below the
limit values
Check the power supply,
check all electrical connections
(cables and plug connections)
Rapid flashing of the LEDs
Invalid operating mode
Disconnecting and reconnecting
the voltage supply
Sensor does not provide
values in the vibration
range.
Manual trigger selected, but no
trigger received
Select automatic trigger or send
corresponding signal.
Sensor does not provide
updated vibration data.
The sensor is in
Snapshot
mode
for reading out the raw data or
spectrum.
Set
Snapshot
mode to 0 (normal
operation).
Sensor does not provide
data in vibration range in 2
axes.
Sensor is configured in the sin‐
gle-axis operating mode
Configuration for multi-axis
operation.
Teach-in is not performed.
The sensor is in manual trig‐
ger operating mode and is not
receiving a trigger. No new data
blocks can be supplied.
Select automatic trigger or send
trigger signal according to the
required number of blocks.
Sensor provides no alarm
or only a very brief
alarm when limit value is
exceeded.
The alarm reset time has been
set to 0 or a small value.
To receive all alarms that occur,
the alarm reset time should be
set to -1.
The alarm delay time has been
set to a very large value.
The alarm delay time should be
set to 0 so that limit value over‐
shoots always occur as alarms.
Shock data is not recorded
and updated.
Threshold for shock detection
has been set to 0 g.
Set threshold for shock detec‐
tion to
≥
10 g
