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.

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.
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)
- ashes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.
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ashesofthegreenOKL2LEDandtheredWARNINGL1LEDandfromtheashinglight(ifthere
is one) connected to the specially programmed control unit outputs.

Triggering of a photocell
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.

Triggering of the STOP input
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.
