Drive - Instruction Manual
6.7.1 Space Percentage
If set, this option allows the Aux Output Relay contacts to send a signal during door opening that relates to a pre-set distance percentage
(in comparison to the total door opening) and a signal during the door closing up to the same opening percentage.
6.7.2 Gong While Opening
If set, this option allows the Aux Output Relay contacts to send a signal during the door opening (to a device not supplied by Sematic).
6.7.3 Thermic alarm signal
If set, this option allows the Aux Output Relay contacts to send a signal during a thermic protection alarm presence.
6.8 FORCED CLOSING (NUDGING)
If the main lift controller operates with a disabling photocell circuit (or similar device), after several failed attempts at closure, it is
possible to command the closure of the doors in low speed (forced closing), by closing the 15-22 connector pins by means of a relay
(voltage free contact).
During the closing cycle the connector 21 (Gnd) and the connector 15 (+24 V) are activated for the direct use of a 24 Vdc max 100 mA
buzzer (device not supplied by Sematic) or adequate relay.
Param. code 27 (00 -> Rev. Sense OFF)
Closing force detection is disabled
Param. code 27 (01 -> Rev. Sense ON)
Closing force detection is enabled and set by Fset value parameter (PC 09)
6.9 FIRE FIGHTING (PARAM. CODE 19)
The FIRE FIGHTING option is possible for specific installations where the main lift controller contains the applicable functions.
For operative details of the complete lift installation, refer to the following standards:
•
BS5588: Part 5: 1991
•
EN81-72: 2003
•
ASME A17.1: 2000
•
AS-1735.1: 2003
The Fire Fighting option has a dedicated input, Kff.
When Kff switches from OPEN to CLOSED the directly or completely connected light barriers or similar devices are ignored, as these are
assumed to be devices which may be affected by smoke or heat due to fire conditions; the reopening system can be set to either ignore
mechanical obstacle (parameter 19 = 0) or to have its sensitivity reduced (parameter 19 = 1).
Warning
: the default setting is “reduced sensitivity” (parameter 19 = 1). Change of this parameter is according to customer’s choice,
following careful assessments and check of the standards required in the Country of installation.
At the end of the first closing cycle the main lift controller takes the car to the Fire Fighters’ access floor, if it is not already there.

Door Controller operates only on signals coming from the main lift controller. Even during the opening cycle
it is possible to reverse the movement by deactivating the Ka signal and activating the Kc signal.
The Main lift controller must steadily monitor the continuous pressure of the car push-buttons (open door and floor call push-buttons),
performed by the Fireman controlling the installation.
During a closing cycle, the release of the floor call push-button must release the Kc signal, insert the Ka signal and cancel the call.
During an opening cycle, the release of the door opening push-button must release the Ka signal and insert the Kc signal.
At the end of the closing or opening run (detectable through the Lc and La signals respectively) the main lift controller can detect the
release of the floor call or open door push buttons without inserting the Ka and Kc signals respectively; the door controller will wait for a
new control signal.
Important! Other systems that interface with the Car Door Operator reversing functions (e.g. optical barriers/photocells etc.) which are
operated by the main lift controller and which may be affected by smoke or heat should be deactivated by the main lift controller itself.
6.10 DOUBLE TB
This function allows the Door Controller to store two different
door opening widths (TB), for different floors and on the same
side, envisaged in the same installation and operated by the
same car door drive.
A magnetic switch, mounted on the Door Operator by Sematic,
is connected to the 15-41 connectors and is operated by
magnets mounted only on the landing doors with different
door opening widths (TB)(the smaller) by means of a special
support plate (see drawing). This signal allows the Door
Controller to distinguish floors with different opening width.
•
Complete a self-learning cycle (see
“8.3 Self-learning cycle activation by means of the handset” a pag. 36
)
•
Take the car to a floor with the different TB: upon receiving the Ka signal (given by the main lift controller or manually by the
installer) the Door Controller will automatically carry out a second self learning cycle if the magnets on the landing doors with
different TB are correctly positioned.
