FURTHER DETAILS AND DIAGNOSTICS
10.1 - Further details
10.1.1 - Signals when switching ON
When the DPRO500 control unit is switched ON, the reaction of the green OK
L2 led and the red WARNING L1 LED is important, as shown in Table 4. In
particular, it indicates whether:
- The recognition of the Opening and Closing positions is correct;
- The recognition of the (sensitive edge) safety device is correct and what kind
of safety device has been recognised.

After providing the signals shown in Table 4, the DPRO500 control unit shows
any errors through Diagnostics using the OK L2 led and the WARNING L1 LED.
10.1.2 - Other functions
Status and diagnostics indicator (terminal on the keyboard)
The control unit allows you to connect a 24V-5W max. indicator light to the
"indicator" terminal on the push button panel housed inside the box cover (Fig.
21: 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.
10.2 - 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.

2 flashes - short pause
2 flashes - long pause
4 flashes - short pause

6 flashes - short pause

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 10.2).
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.

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".

Solution
Disconnect and reconnect the power supply. If the error persists, run
the "Total deletion of the control unit memory" (paragraph 7.8) 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 7.9).
Reverse the direction of rotation of the encoder by moving DIP switch
2 to ON (see paragraph 7.10). 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. 14).
