"indicator" terminal on the push button panel housed inside the box cover (Fig.
18: terminal 1 -, 2 +). The "indicator" can be installed on the cover itself, by
making a hole on the latter, or it can be installed outside the control unit at a
maximum distance of 2 m from the latter.
CAUTION! - The output is not protected against short-circuits.
This "indicator" functions in the following way:
- off when the safety chain is open (ALT inp, red STOP button, thermal protec-
tion or release)
- flashes 0.5 s ON, 0.5 s OFF when it works properly
- shows the same diagnostics as the red L1 WARNING LED when there are
"serious errors" (Paragraph 5.2).
Setting the pause time for automatic closing
1 Set DIP switches 3 and 4 to ON.
2 Send a command to open the door so as to move the door to its fully open
position.
3 Once this position is reached, wait for a period of time equal to the required
pause time for automatic closing and then command the door to close. The
pause time for automatic closing is now saved.
In order to change the pause time, set dip 3 and 4 to OFF and then back to

5.2 - DIAGNOSTICS

Some devices are equipped to display messages to identify their status and faults. The following table describes the various alarm signals according to the type
of problem. These alarm signals are provided by appropriate flashes of the green OK L2 LED and the red WARNING L1 LED and from the flashing light (if there
is one) connected to the specially programmed control unit outputs.
Signal Cause
2 flashes - short pause Triggering of a photocell
2 flashes - long pause
4 flashes - short pause Triggering of the STOP input
4 flashes - long pause
6 flashes - short pause Manoeuvre limiting device
6 flashes - long pause
9 flashes - short pause Automation system locked
9 flashes - long pause
The LEDs come on for 3 Lock automation
seconds
2 flashes of 1 second with Automation system released
pause of 1.5 seconds
Certain signals can be cancelled by pressing the red STOP button
Signal Cause
5 flashes – short pause EEPROM error - Error in the
5 flashes – long pause internal parameters of the
control unit
2 flashes – short pause Safety Test Error
2 flashes – long pause
3 flashes – short pause Error in direction of rotation
3 flashes – long pause of the Encoder
4 flashes – short pause Error with safety limit
4 flashes – long pause switches
6 flashes – short pause Error with contactor
6 flashes – long pause
7 flashes – short pause RS485 communication error
7 flashes – long pause on Encoder
8 flashes – short pause Encoder error
8 flashes – long pause
9 flashes – short pause Error in limit switch
9 flashes – long pause acquisition
10 flashes – short pause Error in movement time-out
10 flashes – long pause
Note - The diagnostic signals provided by flashing LEDs stop when the control unit is given a command.
By using an external flashing light*, the diagnostics signals continue for two sequences of flashes (e.g. "3 flashes – short pause – 3 flashes –long
pause" repeated twice).
* Configured with the Oview programmer as "Flashing Light 1" IMPORTANT: To connect the external flashing light, you need to use the additional
NDA040 board (not supplied).
ON. At this point you must repeat the sequence of opening, pause time and
closing.
CAUTION! - When DIP switch 4 is moved to the OFF position, the pause time
is deleted.

DIAGNOSTICS GREEN OK L2 LED
Solution
At the start of the manoeuvre, one or more photocells fail to give the enable
signal; check for obstacles and whether the photocells are interfering with each
other's IR.
At the start of or during the manoeuvre, the STOP or ALT input was triggered;
identify the cause.
---
Send the "Release Automation" command or command the
manoeuvre with "Step-by-Step High Priority".

DIAGNOSTICS RED WARNING L1 LED
Solution
Disconnect and reconnect the power supply. If the error persists, run the "Total
deletion of the control unit memory" (paragraph 3.8) and rerun installation. If
the condition persists, there may be a serious fault and you will need to replace
the electronic circuit board.
Rerun the recognition procedure for the safety devices connected to the con-
trol unit (paragraph 3.9).
Reverse the direction of rotation of the encoder by moving DIP switch 2 to ON
(see paragraph 3.10).
The door has gone past the safety limit switches during Opening or Closing.
Move the door manually to about half way up using the emergency manoeuvre
system (see the manual of the motor) and press the STOP button on the cover
in order to restore operation. Assess whether you need to change the previ-
ously acquired Opening/Closing positions.
Disconnect all the power lines for a few seconds, then try sending a command
again; if the problem persists, there may be a serious fault on the circuit board or
on the connections of the motor. Carry out checks and replace parts, if required.
Check that the motor-control unit cable is connected correctly, in particular the
encoder cable (6 coloured wires).
Check that the motor-control unit cable is connected correctly, in particular
the encoder cable (6 coloured wires). Rerun the recognition procedure of the
Opening and Closing positions.
Repeat the recognition procedure of the Opening and Closing positions.
The default setting for the movement time-out is 60 seconds. Check whether
there are any obstructions to the movement of the door or whether the door
has actually performed the movement. Check whether the duration of the
timer has been changed (using the Oview programmer if available). Repeat the
recognition of the Opening and Closing positions.
