2Generalities
2.1 Intended use
The CDD 5.0 (Computec Door Drive 5.0) device is an electronic system that permits to operate in practice all
the lift door operated by the motors described in the table “- Table 2: compatible motors data”.
The CDD 5.0 controls the lift door opening and closing automatically, according to the commands received
from the main lift controller of the lift system, and controls the time intervals, currents, speed profiles,
different external devices directly pluggable to the drive, and the possible anomalous behaviour as over-
voltages, connections interruptions, and so on.
2.2 System overview
The CDD 5.0 system is a part of the complete lift door operator, consisting in:
-Mechanical door operator:
oHeader
oCarriages
oBelt
oMotor
-Door Drive (the CDD 5.0)
-Contacts Interface to the main lift controller
Following it is reported the connection diagram of the device:

2.3 Compatibility for applications and motors
The CDD 5.0 can be applied to all the lift door operators that use the motors reported in the compatibility
table, in particular for that operator for which it is pre-set the configuration of the mechanical transmission
(skate, motor pulley, …).
It is possible in any case to adapt the system configuration to other door operator that uses the same
motors, setting manually the specified parameters values. It is strongly suggested, in this case, to previously
contact directly Computec technical support, for information about compatibility and configuration.

3Installation
Before proceeding to the installation, verify the necessary safety devices:
In addition verify the necessary instruments to perform all the operations:
Be sure to work in full safe conditions, setting the inspection mode on the lift before starting any operation.
3.1 Preliminary mechanical checks
The installation of the door drive has to be performed by expert technical personnel, having all the
professional requirements expected, based on the active law in the installation country.
Before proceeding with the installation of the door drive it is necessary to:
-Check the correct and good status of the door operator installation:
oCorrect installation of the door panels
oCorrect installation of the carriages
oCorrect installation of the transmission (belt connection, belt)
oCorrect installation of the gear-motors, according to table “- Table 2: compatible motors
data”
-Check that the panels movement is free, without obstacles overall the complete door space.
-Check the material of the box:
oCDD 5.0 door controller
oRetrofit fixation bracket to be fixed on the controller, in case of retrofit

3.2 Mechanical Installation
The mechanical installation of the door drive has to be executed according to the controller type to replace.
For this reason the CDD 5.0 is supplied with the retrofit fixation bracket. The following table shows the two
fixation possibilities.
Fixation type
Description
Installation with retrofit bracket
1. Switch off the main power supply
2. Remove all the connection from the old door
controller
3. Remove the door controller to be replaced
4. Remove the cover of the CDD 5.0. Apply the
retrofit bracket to the CDD 5.0
5. Install the door controller, using the fixation
holes aligned to the holes present on the
operator.
6. Apply the previous fixation screws
Installation on direct compatible systems
1. Switch off the main power supply
2. Remove all the connection from the old door
controller
3. Remove the door controller to be replaced
4. Remove the cover of the CDD 5.0
5. Apply the door drive using the four fixation
points present on the operator.
- Table 5: mechanical installation of the drive –
3.3 Preliminary electrical checks
Verify the presence of the correct supply voltage, as reported in the table “- Table 1: door drive data”.
Once the mechanical installation of the CDD 5.0 drive is completed, and the CDD 5.0 is fixated to its holding
(with retrofit bracket or directly), proceed as reported below.

4.1.1 Working Modes
The CDD 5.0 door drive can activate the following working modes:
MODE
DESCRIPTION
NORMAL
This is the normal automatic working mode.
The door drive after the power on enters in this working mode.
In this working mode the controller executes the movements requested from the
commands sent by the MLC.
INSPECTION
This is the Inspection mode of the door drive.
In this working mode the door drive does not accept commands from MLC, but executes
the opening/closing movements according to the pressure of “<>” and “><” buttons on
the door drive front panel.
ATTENTION: in this working mode the external reversing sources are disabled.
CONFIGURATION
This is the programming mode, where it is possible to configure and set all the
parameters accessible front the door drive front panel.
DIAGNOSTIC
The controller enters in this working mode, when a recognized device is connected to
the X8 plug.
The door drive recognizes the connection of the external device and, from any of the
previous working mode, enters in this one.
In this working mode, the controller communicates with the external device for all the
diagnostic/configuration/monitor/upgrade operations.
When the external device is disconnected, the controller returns automatically in
Normal mode.
UPGRADE
This is the mode in which the controller enters during the firmware upgrade.
- Table 11: door drive working modes -
Please refer to paragraph 4.3 “HMI: front panel user interface” about the use of the door drive front panel,
and how to move from one to another working mode.

4.2 Connections
4.2.1 MLC signals connection
The present paragraph reports the connections between door drive and MLC, focusing the attention on the
connection for the common voltage to use, in case it is the common voltage from door drive (24_DD) or
from MLC (24_EC). The door drive has a 24Vdc auxiliary common voltage for the wiring of commands, with
maximum load limit current of 1A.
Common Voltage
Connection
Notes
24V_DD
The 37-38 bridge must be present.
The MLC uses the 24Vdc from the door drive as
common voltage for commands and door drive
outputs.
Commands: DOC, DCC, RSC, FFC. As example only the
first two are reported in the diagram: the others
follows the same connection rules.
The door drive outputs, being dry contacts, can be
connected to another common voltage, if requested by
the MLC.
The door drive outputs have a dedicated common
voltage available for each output.
In the diagram they have been grouped in a single pin,
that represents a series of bridges between X2.4,
X2.16, X2.18, X2.35
24V_EC
Remove the 37-38 bridge and connect the external 0V
from MLC to the 38 pin.
Commands: DOC, DCC, RSC, FFC. As example only the
first two are reported in the diagram: the others
follows the same connection rules.
If local wired contacts are present:
1. use the same common voltage active for the
commands.
2. use the auxiliary 24Vdc of the door drive, recovering
the 37-38 bridges. In this case check the compatibility
between 0V_DD and 0V_EC.
The door drive outputs keep the same common voltage
from MLC, used for the commands.
The door drive outputs have a dedicated common
voltage available for each output.
In the diagram they have been grouped in a single pin,
that represents a series of bridges between X2.4,
X2.16, X2.18, X2.35

4.2.2 Direct connection of optical detector to the CDD 5.0
The present paragraph illustrates the connection of the external reversing sources (detector, light curtains,
photocells) directly to the door drive, both as dry contacts or as devices that need also supply voltage.
The X9 plug permits to directly connect a PNP device (N.O. or N.C.) to the CDD 5.0: the door drive gives the
supply voltage for the device, as reported in the following table:

Free pin: it may be used to fix the connection between RX and TX parts of the
detector
- Table 13: direct connection of the optical detector -
NOTE: if it is necessary to connect a detector with N.C. output, reverse the input signal polarity by the
parameter described in the paragraph 5.5.2 “PC21: reversing inputs logic settings”.
NOTE: if it is necessary to connect a NPN detector, please contact Technical support per the dedicated
instructions.
4.2.3 Connection of input signals from optional local contacts
The present paragraph describes how to connect to the door drive the signals from the special local
contacts: EOC, DTBC AUXC.
In this case a magnetic switch is normally installed on the door operator (car side), while on the floor side it
is installed a support plate with two magnets that permits the commutations of the magnetic switch, that
will be active only when the car is between the two magnets (car at the floor).
The magnetic switch should be then connected to the desired pin of the door drive. Refer to the paragraphs
related to the different functions, for the specific descriptions.
