2 WHAT IS THE SRS DC-PWM©?
The System consists of:
• a Car Door Operator (1)
• a microprocessor-based Door Controller (2)
• a DC Motor (3) with feedback signals (4)
• a 230/115Vac - 24Vac transformer (5)
The "Sematic SRS DC-PWM©" controller automatically controls the opening and closing of the lift doors, monitoring the timing, current
variations, speeds (high speed, low speed), various safety systems (reversing system, etc.) and faults (high voltage, signal failure, ...).
There are two independent speed curve profiles for the opening and closing cycles (6) which can be modified by means of the door
controller regulation trimmers. or by means of the Sematic handset (an optional 8 digit keypad and display accessory which can be
connected to the card by an RJ45 plug).
The handset (7) is a key pad that allows viewing and modification of the function parameters stored in the controller.
It is important to use the Sematic handset for installation or maintenance, as it enables viewing and/or variation of the Encoder
parameters, systems, and operation errors.
Furthermore, it is possible to use the Sematic handset directly from the inside of the car (8).
Making it possible to monitor and modify the door operating parameters from a completely safe position, and also to control the
movement of the coupled car and landing doors during their effective operating cycle.
Warning: please note that SRS DC-PWM© door controller has a power limitation and is available only with reduced size doors.
If the door installation does not allow the correct operation of the doors, alternative high powered drives are available.
Please contact our sales department.
Note: the pictures on this document are examples only; real components appearances may differ according to supplied configuration of
door operator and motor.

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).

5 INSTRUCTION WITHOUT HANDSET
5.1 AUTOMATIC MODE
• All the signals sent by the main lift controller and by the external devices (photocells,etc.) are always active except as in note (*).
• If an opening signal is given by the main lift controller, the red led on the door controller printed board starts to ash until the door
reaches the La opening limit (red led on, not ashing).
• If a closing signal is given by the main lift controller, the red led on the door controller printed board starts to ash until the door
reaches the Lc closing limit (red led on, not ashing).
• In case of signal loss or failure of the main lift controller the door controller immediately stops the door movement.
Note (*): in manual mode the main lift controller signals are not active; if CLS or OPN switches are pressed, the main lift controller signals are automatically
excluded.
5.2 MANUAL MODE
To test the correct door operator function before connecting the main lift controller signals, it's possibile to open or close the door through
the two switches [CLS] and [OPN] on the printed board.
• Keep pressed the [OPN] switch to open the door, the red led on the door controller printed board starts to ash until the door reaches
the La opening limit (output contact La open - red led on, not ashing).
• Keep pressed the [CLS] switch to close the door, the red led on the door controller printed board starts to ash until the door reaches
the Lc closing limit (output contact Lc open - red led on, not ashing).

6 FUNCTIONS
6.1 REVERSING SYSTEM FORCE
The reverse motion torque parameter sets the sensitivity degree to detect an obstacle during the door closure, thus giving the reopening
command. The parameter's value can be manually set with a regulation trimmer [IM] or by means of the handset from a minimum force
(high sensitivity) to a maximum force (low sensitivity).
Please note that a minor sensitivity corresponds to higher values and vice versa.
The reversing system is INTERNAL, the reopening of the doors due to obstacle detection is solely controlled by the Door Controller and
door reopening is signalled to the main lift controller through the IM contacts (1-4 contacts normally closed, 2-4 contacts normally open).
6.2 FORCED CLOSING (NUDGING)
In the case of photocell failure, 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 using a relay (voltage free contact).
6.3 MOTOR ROTATION DURING CLOSING
This function fixes the motor rotation during the closure command.
The default value gives the motor a clockwise rotation while closing; to set an anticlockwise rotation to the motor during closure,
simultaneously press for 5 seconds the buttons [CLS] [OPN] [SELF-LRN] on the electronic board or alternatively select the option shown
on the handset display.
The controller resets and the motor rotation is inverted.
Just follow the same instructions to reset the motor in the clockwise rotation.
6.4 SKATE TYPE (INSTRUCTION WITH HANDSET)
This function allows the user to set the skate type:
• Standard (STD) skate (Default): the speed profile setting are optimized for the Sematic standard ALU skate type.
• Expansion (EXP and EXP-B) skate: the speed profile setting are optimized for the Sematic 2000 US Expansion skate type.
00 - STD Skate (Aluminium skate)
01 - EXP Skate
Use this setting when you have a single hole in the upper
fixing plate (left picture) or you have two holes and you are
connecting the belt to the lower one (right picture)

16
www.wittur.com
Changes can be made without notice
PM.2.004922.EN - 810-000-000 SRS DC-PWM©· Edition 22 July 2020
02 - EXP Skate-B
Use this setting when you have two holes in the upper fixing
plate and you are connecting the belt to the upper one
Setting a different skate type means telling the controller that different opening dimensions have to be used (20mm std, 90mm exp and
120 mm exp type B) and this allows correct operation in opening and closing cycles.
After selecting the skate type, confirm in sequence the following options:
• Skate Space
• Skate Low Speed
• Disable reverse. space
• OP. Acel. Start
• CL. Decel. End
6.5 CLOSING REST TYPE (INSTRUCTION WITH HANDSET)
This function allows the user to choose the closing parking mode:
6.5.1 Motor on (default)
The motor is powered during the closing door parking condition and the operator skate arms are closed.
6.5.2 Motor off
This option has been introduced for decrease/avoid the power consumption of the plant (so to preserve the use of the motor) when it is
found in close position.
Important note: during the car travel it is necessary that the Main Lift controller gives the closing Kc command, to allow the skate arms
closing during the movement.
6.5.3 PM activation Delay (Default 300 sec.)
This sub-parameter represents the delay in entering the open skate parking phase after the activation event represented by the disabling
of the closing command KC. So the system waits for a time equal to the parameter, before opening the skates and going into energy
saving condition.
6.5.4 PM Opening space (Default 20 mm for STD skate, default 90 mm for EXP skate, default 120 mm for EXP-B skate)
The value represents the size of the space reached by the skate when it is completely open during open skate parking.
6.5.5 PM position error (Default 5 mm)
This sub-parameter represents the space threshold (with relation to the open skate parking point represented by the PM ACTIVATION
DELAY parameter) within which the panels can move. When the set value is exceeded the controller loses the door closed signal LC and
activates immediate automatic closure of the skate. During this last operation the Main Lift Controller should however give the closing or
opening command to the door operator.
6.6 MOTOR (INSTRUCTION WITH HANDSET)
Controller Sematic Residential System can be used with differents motors as indicated at paragraph 4.1.
As setting deafult the controller automatically recognize the model DC-PWM B105AANX.
Using the DC.PWM B105AAXX model you have to select it manually
6.7 MAX CURRENT END CL (INSTRUCTION WITH HANDSET)
This parameter allows to reduce the current to the motor during the final phase of closing skate.
Keeping OFF (default) if the system is powered through a 24Vac and150VA transformer supplied by Sematic.
Press ON only if the controller is powered with continuous tension (24Vdc) and reduced power (<150VA)
6.8 LA THRESOLD (INSTRUCTION WITH HANDSET)
6.9
This parameter allows the regulation of the activating point of the LA outgoing used for the open door's segnalation.
Default value is 0,08m
• Increase the data to allows the activation of the outgoing LA before the door is completely open.
• Decrease the data to delay the activation of the outgoing LA .
• Note: Excessive reduction of this value could compromise the regular functioning of LA's signal
6.10 ALARMS
The Sematic SRS DC-PWM© controller has the ability to diagnose and record a number of anomalous situations; such diagnostics are
very helpful to the maintenance personnel to assist in locating possible operational problems. When any monitored error occurs, the Door
Controller will signal it with the leds: the red led is on and the green led ashes showing the error code (the ash number corresponds to

are restored; after 5 trials in 5
minutes the system stops operation
and waits for external manitenan-
ce.
Notes:
1. This alarm indicates an excessive strain on the operator's functioning; it is advisable to check that the system has minimum
friction, especially during the opening phase.
2. If both connections (motor and Encoder signals) are inverted, the door opens when a closing signal is received and closes with an
opening signal. The Door Operator is pre-wired and tested by the manufacturer; special attention must be taken when replacing
motor and/or cables.

7 TRIAL OPERATIONS BEFORE SETTING AT WORK
To avoid damage, check that the power supply voltage is within the rated values before connecting. The controller turns off if the power
voltage is under 15 V.
Before the lift is commissioned, a self-learning cycle must be carried out.
7.1 SELF-LEARNING
The self-learning cycle allows the Door Controller to store the running distance between the closing and opening limit. It can only be
activated manually and must be carried out under direct supervision of maintenance personnel (i.e. the Door Controller must store the
correct data).
Important!
• During the self-learning cycle please check carefully that the panels slide freely and that the Door Operator completes its total
expected travel. The self-learning cycle is essential if a replacement Door Controller has been installed.
• Every time the system is re-powered and an opening/closing signal is given (for instance after power supply interruption) it
performs a reset cycle, i.e. it searches for a closing limit at low speed, not a self-learning cycle.
7.2 SELF-LEARNING CYCLE PROCEDURE (WITHOUT USING THE HANDSET)
• Power the system
• Turn “ON” the door controller
• Press the self-learning switch [SELF-LRN]to start up the self-learning cycle.
• Give a closing signal through the [CLS] switch on the printed board or through the main lift controller.
• When a closing command is given, the Door Controller carries out a closing cycle at low speed (both red and green leds are
ashing) or it remains in closed position if the doors are already closed (green led is ashing and red led is on).
• After the doors have completely closed, give an opening command through the [OPN] switch on the printed board or through
the main lift controller opening signal: the Door Controller carries out an opening cycle at low speed (both red and green leds are
ashing) until the door reaches the opening limit. During this operation please check carefully that the operator completes its total
expected travel.
At the end of the opening cycle, the self-learning cycle is complete (red led on and green led off).

7.3 SPEED PROFILE REGULATION TRIMMERS (WITHOUT HANDSET)
To set up both opening and closing speed profiles there are four trimmer on the printed board as shown in the following picture:
• [HI-OPN] trimmer sets the high opening speed (turn-ing it clockwise will set the high opening speed from the minimum speed
value to the maximum speed value)
• [LW-OPN] trimmer sets the low opening speed (turn-ing it clockwise will set the low opening speed from the minimum speed value
to the maximum speed value)
• [HI-CLS] trimmer sets the high closing speed (turn-ing it clockwise will set the high closing speed from the minimum speed value
to the maximum speed value)
• [LW-CLS] trimmer sets the low closing speed (turn-ing it clockwise will set the low closing speed from the minimum speed value to
the maximum speed value)
Note: the trimmer set value is saved in permanent memory only if the trimmer stays inactive for minimum, 2 seconds.
7.4 REVERSING SYSTEM FORCE SETTING (WITHOUT HANDSET)
The reverse motion torque parameter sets the sensitivity degree to detect an obstacle during the door closure, thus giving the reopening
command. The parameter's value can be manually set through the [IM] regulation trimmer (turning it clockwise will set the reversing
system force from the minimum value to the maximum value)
Please note that a minor sensitivity corresponds to higher values and vice versa.

8 INSTRUCTION WITH HANDSET
8.1 HANDSET (OPTIONAL)
Fig. 1 Optional Kit - cod. B147AABX
Recommendation!
Although the handset (see picture 1) can be directly connected by the installer/maintenance personnel to the door controller on the car’s
roof, the ideal situation is to have a connection with the door controller inside the car (see picture 2).
In this way the installer/maintenance personnel can work in absolutely safe conditions and can control the movement of the coupled
doors during their effective operational mode.
To make this connection, ask Sematic for the appropriate adapter cod. B147AABX (see picture 3) (a 16 mm. diameter hole is required in
any chosen position within the Car walls).
Note: when the handset is connected to the controller the display shows the warrantly expiration date (2 years from the manufacturer
date) and the activity hours left before warrantly expiration. Subsequently choose the language by means of the keys äand ãand
confirm the choice through the “OK” key.
Important note: when the handset is connected, all the signals from the main lift controller (but not the K2TB, if used) and Kn are ignored;
this in order not to interfere with the commands sent through the handset.
The output LA and LC are both kept OPEN (not valid condition in normal operation).
If Monitor menu is selected also Kn is monitored. When the MLC Monitor menu is selected, though, the system performs as if the handset
was not connected at all, allowing the complete monitoring of input/output signals by means of the handset.
