4.5 Door Learning function
The door learning function is the basic fundamental operation to be performed, to obtain a correct
behaviour of the system. The CDD 5.0 controller can perform two different door learning procedures:
1. Standard Learning

This procedure permits to learn the door space, from door closed (and clutch closed) position,
to door open position. It can be started directly from the door drive front panel, or by external
device. Before starting the learning procedure, be sure to have pre-set all the parameters that
identify the door operator (PC05 car door lock, PC26 skate type, PC22 closing rotation, PC90
motor type, PC99 MLC interface).
2. Automatic learning

This procedure permits to learn automatically: the door space, the exact skate space measured
on the belt (the skate type too) and the closing rotation. Before starting the learning
procedure, be sure to have pre-set all the other parameters that identify the door operator
(PC05 car door lock, PC90 motor type, PC99 MLC interface). The auto-set procedure allows an
optimal tuning of the controller interfaced to the door operator.
NOTE: please refer to chapter 5, for the parameter list and set-up
4.5.1 Standard Learning by HMI
The standard learning by HMI can be performed following the sequence reported in the table below:
Sequence Notes
Controller power on After main power supply is connected, press key 1
Door operator parameters
configuration Configure PC05, PC22, PC26, PC90, PC99 according to the installed door
operator
Inspection Mode Activation Press key 4 and check INSP led is on
Door closing Press continuously key 3, until the door is completely closed, checking that
the display shows “CL” fixed
Learning mode activation Press key 1 for at least 1s, and check that the display shows “SL”
Learning opening cycle activation Press shortly key 2, until the door starts to open with reduced speed, and the
display shows “SL” blinking.
When the door is completely opened, the display visualisation switch from
“SL” blinking to “OP” fixed. The learning procedure is completed

4.5.2 Standard Learning by external Handset
The standard learning by external handset can be executed simply accessing to the “ Self-learning” menu:
