8.3.2 Signals with the display
In case of anomalies, the display can visualise an error code both during the boom’s movement and when the manoeuvre stops.
The following table shows the error codes that can be displayed.
Table 13
SIGNALS WITH THE DISPLAY
Error code Description Cause Meaning
E01
Memory of the
BlueBus or Stop
devices
There has been a change in the devices
connected to the Bluebus or Stop terminals,
or learning of the devices was never done
The connected devices must undergo the
learning procedure (refer to the “Device
learning” paragraph)
E02
Level memory or the
positions were never
learned
Learning of the positions was probably never
done
The boom’s opening and closing positions
must be learned (refer to the “Learning of the
mechanical stop positions” paragraph)
E03
Limit switches
inverted
E04
Encoder signal
Lack of communication between the sensor
present in the motor and the control unit
Check that the encoder cable is connected
and in good condition
E05
Master-Slave
communication
The Master and Slave control unit are not
communicating correctly between one
another
Check that the cable connecting the Master
and Slave control units is connected and that
the pole markings are observed
Check that the Slave control unit has been
selected and the Master learning phase has
been completed (refer to the “Gearmotor in
SLAVE mode” paragraph).
E06
Parameter memory
reading
Error in the internal parameters of the control
unit
Disconnect and reconnect the power supply.
If the error persists, delete the memory
entirely as described in the “Full deletion of
the control unit’s memory” paragraph and
redo the installation
If the condition persists, there’s a fault or the
electronic circuit board must be repeated
E07
Internal checks and
Class B tests
Error in the internal electric circuits
Disconnect all the power supply circuits; after
a few seconds, reconnect the power supply
circuits and try sending a command
If the condition persists, there’s a fault or the
electronic circuit board must be repeated
E08
Dip-switch
conguration
Probable tampering or failure of the barrier
selection dip-switch
Check that the dip-switch settings match the
factory settings
E09
Lock automation
The automation was stopped by a Lock
command
Send the “Unlock automation” command or
command the control unit with HP SbS
E10
Lack of safety input
(NC) or limit switch
There is no NC safety input or at least a limit
switch
Check the cable connected to the “Safety”
input and the operation of the limit switches
E11
Short-circuit at the
Bluebus output
One or more devices connected to the
Bluebus output have short-circuited
Try sending a command and wait 40 seconds
I02
Intervention of a
photocell
At the start of a manoeuvre or during the
movement, one or more photocells do not
give the enable signal
Check for any obstacles
I03
Intervention of the
motor force limiter
During the movement, the boom experienced
excessive friction
Verify the cause or increase the force level
I04
Intervention of the
devices connected to
the Stop input
At the start of the manoeuvre or during the
movement itself, the devices connected to the
STOP input intervened
Identify the cause
