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:
PIN
DESCRIPTION
NOTES
33
GND
0V pin
32
DETC (IN)
Input pin: connect the status pin of the PNP N.O. or N.C. detector
31
+24Vdc
Voltage supply pin: 24Vdc, 100mA max
30
Free
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.
