Set up Raffaello as elevator car indicator or floor indicator
1) – Elevator car Position Indicator (default)
2) – Hall Position Indicator
Arrow setting up
1) – Direction arrows (default)
2) – Next direction arrows (instructions below)

Next Direction Arrows enabled from input
Arrows light up only on the position indicators with the “NEXT DIRECTION” input powered.If the DEUM Encoder is used, please refer to the relevant manual

Next Direction Arrows locally programmed
Through the addressing procedure one can permanently assign to each indicator the information of the floor on which it is mounted; in this way, next direction arrows only light up at the floor where the elevator car is positioned.

Addressing procedure

1) – Connect all position indicators to the ENCODER or PLAYBOARD controller.
2) – Position elevator car on the floor of the Display which needs to be directed.
3) – Verify that the characters/numbers/letters visualized are the desired ones.
4) – Press and hold the ADV key and wait for the display to flash for 3 seconds to confirm.
5) – Repeat procedure for each floor.
If the DEUM Encoder is used, please refer to the relevant manual

Set up CAN BUS protocol transmission speed
Intermediate floors visualization
Set up floors OFFSET
Set up first visualization
1) – It does not display any numbers
2) – Lowest floor
Set up Parallel position common input
Set up scrolling arrows
1) – Fixed arrows
2) – Scrolling arrows
Enable auxiliary signals
a) – 10 Floor parallel inputs (X01÷X10) + 0 AUX Signals
b) – 6 Floor parallel inputs (X01÷
X06) + 4 AUX Signals (X07÷X10)

Set up the display delay of floor change
The display delay helps avoiding visualization errors during floor change.
Associate the floor position indicator with the duplex controllers
The parameter allows to assign the display (floor) to a unique controller. The Duplex-Light typology includes 2 controllers with a single BDU line and a maximum of 2 displays at the main floor.
This parameter can only be set with the CAN protocol on the Pitagora 4.0 system.
0) – To be associated with the lift car position indicator.
1) – The display will show the information of the MASTER controller.
2) – The display will show the information of the SLAVE controller.
3/4/5/6) – Future uses.

Fault description Raffaello 2,8"
Installation errors The display does not light upCheck for the presence of 12/24VdC voltage.
Make sure that the type of voltage complies with that required (direct voltage, not alternating, not rectified).
Check the correct polarity on the power terminals.
Press the PRG key and make sure that the menu does not appear. In this case the screen is black but without input it could give the idea of being turned off.
The display does not show numbers and/or arrowsMake sure that the type and voltage value comply with those required for the inputs, make sure you have correctly set the type of common.
Long presses of the PRG key are not detected by the display.Update the display to the latest firmware version.
Error messages BLOCKED DEVICE INSERT CODEIf this message appears when you turn on the device, it means that it was not unlocked by mistake during production.
