· Edition 22 July 2020
In order to prevent possible damage to the wiring cables by coming into contact with the drive belt, they are fixed to the header as shown
in the following image:
Note
: In case of motor replacement be sure to bind the excess cable lenght as above pictured, to avoid any contact of the motor cable with the driving belt.
Warning:
•
to avoid possible induced currents within field wiring, it is recommended to shield the Ka and Kc signals (connector pins 3, 5 and
15) with grounded, shielded cables.
•
Changes made to the factory wiring length or position can damage the EMC system characteristics and is not recommended.
4.1.1 Detector/Photocell/Barriers: Signal-Only Connection to the Door Controller (Direct Connection)
This connection requires a dry (voltage free) external relay contact connected to the Door Controller Connector pins 15-23.
It is possible to connect the single output signal from a photocell (or similar device) formed by a voltage free contact, so that the door
controller will directly receive the command to re-open. The photocell (or similar device) has therefore an independent power supply and
sends only its outgoing signal to the Sematic SRS DC-PWM© controller.
During the reopening of the door the controller sends a signal to the main lift controller through the IM relay contact (green led is on).
4.1.2 Detector/Photocell/Barriers: Complete Connection to the Door Controller
Complete Connection means that the device is powered by, and sends the re-open signs directly to the Sematic SRS DC-PWM© controller.
The controller then sends a signal to the main lift controller through the IM relays contact (green led is on).
It is possible to have the complete connection of detectors or photocells with a 24 Vdc max 100 mA supply and a PNP N/O output, through
the connector pins:
33 GND
ground connector pin
32 IN
PNP N/O or N/C signal from
detector/photocell/barrier
31 + 24 Vdc
Vdc power supply to
detector/photocell/barrier
30 NC
dummy free connector pin
(it can be used as a dummy connector for connection
between the detectors system components).
