Signals With The Display - Nice M-BAR Serie Instrucciones Y Advertencias Para La Instalación Y El Uso

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.
SIGNALS WITH THE DISPLAY
Error code Description
Memory of the
BlueBus or Stop
E01
devices
Level memory or the
positions were never
E02
learned
Limit switches
E03
inverted
Encoder signal
E04
Master-Slave
E05
communication
Parameter memory
E06
reading
Internal checks and
E07
Class B tests
Dip-switch
E08
coniguration
Lock automation
E09
Lack of safety input
E10
(NC) or limit switch
Short-circuit at the
E11
Bluebus output
Intervention of a
I02
photocell
Intervention of the
I03
motor force limiter
Intervention of the
devices connected to
I04
the Stop input
Cause
There has been a change in the devices
connected to the BlueBus or Stop terminals,
the learning stage was not performed, or the
connected devices are not compatible with
the control unit
Learning of the positions was probably never
done
Lack of communication between the sensor
present in the motor and the control unit
The Master and Slave control unit are not
communicating correctly between one
another
Error in the internal parameters of the control
unit
Error in the internal electric circuits
Probable tampering or failure of the barrier
selection dip-switch
The automation was stopped by a Lock
command
There is no NC safety input or at least a limit
switch
One or more devices connected to the
Bluebus output have short-circuited
At the start of a manoeuvre or during the
movement, one or more photocells do not
give the enable signal
During the movement, the boom experienced
excessive friction
At the start of the manoeuvre or during the
movement itself, the devices connected to the
STOP input intervened
Meaning
Please disconnect any non-compatible
devices and run the learning stage for the
connected devices (see paragraph "Device
learning")
The boom's opening and closing positions
must be learned (refer to the "Learning of the
mechanical stop positions" paragraph)
Check that the encoder cable is connected
and in good condition
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).
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
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
Check that the dip-switch settings match the
factory settings
Send the "Unlock automation" command or
command the control unit with HP SbS
Check the cable connected to the "Safety"
input and the operation of the limit switches
Try sending a command and wait 40 seconds
Check for any obstacles
Verify the cause or increase the force level
Identify the cause
