Messages Shown On The Display - Dea 124RR Notice D'emploi Et Avertissements

If SIC input is unused, it is necessary to short circuit it to terminal no. 11.
If you power external safety devices through 24VSIC output (terminal no. 22), their pro-
per working is tested before each manoeuvre.

Messages shown on the display

124 RR control board allows you to visualize on the display several messages concerning its working
status and any malfunction:
Message
Gate is closed
Gate is open
Opening under way
Closing under way
While in step-by-step mode, the control board awaits further instructions after a start command
Stop input activated
SIC activated while working in barrier mode
Message
They point out that the gate has
exceeded:
- (Err1), the max allowed number of
reversals (50) without ever reaching
the end of stroke (or limit switch) while
closing;
- (Err2) the max number of uninter-
rupted operations (10) of the anti-
crush safety device;
Therefore an "emergency maneuver"
is under way: the control board sets
automatically the motors in a slow
down phase and searches the stops
(or limit switches) in order to reset the
positioning system. Once the stops
(or limit switches) while closing are
found again the message disappears
and the control board awaits further
instructions "----" and then resumes
working normally.
External photocells and/or safety devi-
ces are activated or out of order
The motor is not connected or it si-
gnals control board failure
The control board power supply vol-
tage has exceeded the allowed range
Possible motor overheating due to
obstacles hindering the gate/door
movement. The control board does
not respond to instructions

Possible solutions
In case the gate is not properly closed after the
emergency maneuver (maybe because of false
stops or obstacles due to mechanical frictions),
proceed as follows:
- Disconnect the power supply, check manually that
no particular frictions and/or obstacles are present
during the complete stroke of the door/gate. Leave
the door/gate half-open.
- Connect the power supply again and subsequen-
tly give a start pulse. At this point the door/gate will
start to close in slow down phase until reaching the
stop (or end of stroke). Make sure that the maneu-
ver is properly completed. Adjust force and motor
speed values, if needed.
If the gate keeps working inappropriately try to
repeat the motor stroke memorization procedure
(see paragraph 8.2)
Make sure that all safety devices and/or photocells
installed are working properly.
Make sure that the motor is properly connected. If
the message reappears change the control board.
Make sure that power supply tension on faston 1-2
is 22 V ~+/-10%, and on faston 3-4 is 27 V
+/-10%.
Remove any obstacle and wait until the message
"Err6" is replaced by message "bLOC" and the
control board responds to instructions again (a few
seconds)
