Diagnostics - Nice DPRO500 Instrucciones Y Advertencias Para La Instalación Y El Uso

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 6.2).
Setting the pause time for automatic closing
1 Set DIP switches 3 and 4 to ON.
2 Send a command to open the gate so as to move the gate 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 gate 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 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.

6.2 - 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 Or inverted limit
switch
4 flashes - short pause Error with safety limit switches
4 flashes - long pause
6 flashes - short pause Error with contactor
6 flashes - long pause
7 flashes - short pause RS485 communication error on
7 flashes - long pause Encoder
8 flashes - short pause Encoder error
8 flashes - long pause
9 flashes - short pause Error in limit switch acquisition
9 flashes - long pause

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 in-
terfering with each other's IR. When the safety devices have intervened,
the automation can be controlled with a person present through the
wired controls. It is not possible to send commands via radio.
At the start of or during the manoeuvre, the STOP or ALT input was
triggered; identify the cause. When the safety devices have intervened,
the automation can be controlled with a person present through the
wired controls. It is not possible to send commands via radio.

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 control unit (paragraph 3.9).
Reverse the direction of rotation of the encoder by moving DIP switch
2 to ON (see paragraph 3.10). If the motor mounts a mechanical limit
switch, reset the error by pressing the STOP button and invert the
opening limit switch connection with that of the closing limit switch
at the LIMIT SWITCH terminal (Fig. A - page 4).
The gate has gone past the safety limit switches during Opening
or Closing. Move the gate 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 previously acquired Open-
ing/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 recogni-
tion procedure of the Opening and Closing positions.
Repeat the recognition procedure of the Opening and Closing posi-
tions.
