• For the Door Operator mechanical installation refer to the “Installation and maintenance of Sematic doors”
manual.
• 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.
4.3 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.
If desired, 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 Drive System© controller.
Reopening is operated according to the REVERSING SYSTEM, LIMITED DOOR REVERSAL EFFECT and PROTECTIVE
DEVICE LOGIC settings (see sections § 6.2 (pg. 21), § 6.3 (pg. 21) and § 6.9 (pg. 22)).
4.4 DETECTOR/PHOTOCELL/BARRIERS: COMPLETE CONNECTION TO THE DOOR CONTROLLER
Complete Connection means that the device draws its power supply from and sends the re-open signal directly
and only to the Sematic Drive System© controller.
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 or N/C output, through the connector pins:
OUTGOING SIGNALS FROM THE DOOR CONTROLLER
Signal Connector Pins Contact type & Normal state Notes
Opening limit switch contact La Connector pins
16-17
These connections provide dry
(voltage free) contact.
The contact is open when the door
is fully open.
Contact rating: 3A 250Vac 30Vdc
Closing limit switch contact Lc Connector pins
18-19
These connections provide dry
(voltage free) contact.
The contact is open when the door
is fully closed.
Contact rating: 3A 250Vac 30Vdc
Reversing system signal IM Connector pins
1-4
These connections provide dry
(voltage free) contact.
(contact normally closed)
This signal is generated by dry
(voltage free) Form C contacts
(relay within the Door Controller)
and is activated only when either
a mechanical obstacle (excessive
force) prevents the doors from
closing, or a signal is received
from an external safety device
that is connected to the door
controller.
It is used to signal the main lift
controller to interrupt the door
close command and give a door
open signal. Contact rating: 3A
250Vac 30Vdc
Connector pins
2-4
(contact normally open)
Auxliary autput signal AUX Connector pins
34-35
These connections provide dry
(voltage free) contact.
(contact normally open
These contacts can be used to
signal that a particular (pre-set)
door opening distance has been
achieved, or as a Gong or Buzzer
while the door is opening or as a
Thermic alarm signal.
Contact rating: 3A 250Vac 30Vdc.
Connector pins
35-36
(contact normally closed)
Motor Connector pins
43-44-45
Factory-prewired connector
Acoustic alarm (BUZZER)
Optional
Connector pins
15-21
These connections provide a
24Vdc, 100ma contact. Contact is
open when not active.
