parameters is not allowed. The default parameters are not universal and will not
provide optimal conditions of door operation. Specifically compliance with
regulations related to the maximum kinetic energy cannot be achieved without
entering correct door characteristics
2. INTRODUCTION
SDK-500 is an electronic controller of automatic elevator door. It ensures optimum
operating conditions for doors of up to 400 kg. It was designed to work with drives fitted with
shaft encoders powered with 5V DC, which generate from 150 to 999 pulses per centimetre of
linear door motion.
Device automatically calculates door motion parameters (e.g. speed profile, acceleration and
deceleration points, acceleration values) based on the door physical characteristics (weight
and width) such as to ensure optimum operation of the drive.
Because of large value of allowable input currents, there are new menu options. Beside
parameters corresponding to door weight and door width, it is important to set correct values of
tightening force and reverse force. Incorrect settings (too high) of current value corresponding
to tightening force may cause damage to the motor.
SDK-500 menu allows for setting of the current corresponding to tightening force -
separately for open door and closed door positions. It is also possible to zero the tightening
force while elevator is stopped (menu option: tightening force while {CLOSE INP.} signal – if it
is supported by elevator's main controller).
Once the automatic calibration routine is completed, the calculated settings are stored in
non-volatile memory of the controller. The SDK-500 controls the door drive such as to meet
the requirements of norms regulating the maximum driving force and the maximum kinetic
energy of the door. Thanks to continuous monitoring of the drive parameters the SDK-500 can
detect increasing motion friction of the drive and alert the service person that maintenance is
required.
All important operation information is presented in a clear manner on the built-in, backlit
LCD display.
The SDK-500 ships in a metal housing that ensures protection against mechanical
damage as well as adverse environmental conditions.

3. CONTROLLER INSTAL LATION
WARNING:
• Read the basic safety requirements on page 4 prior to starting the installation.
• Ensure that the power supply network voltage corresponds to the nominal
voltage stated on the unit’s identification label.
• Power supply terminals and other parts posing hazard of electric shock must be
protected from unauthorised access
3.1. INSTALLATION
Install the controller such as to minimize the length of electrical connections between the
controller and the motor / encoder unit. Use the four mounting holes in the base of the
controller housing to secure the device in its mounting position.
Select mounting position for the controller such as to minimize the risk of inadvertent
stepping onto its housing by elevator service personnel, but to ensure easy access to LCD
display and keypad.
3.2. ELECTRICAL CONNECTIONS
WARNING:
• It is strictly required to provide good grounding of controller metal housing and
transformer cover, using separate grounding wire to appropriate grounding
terminal.
• Motor and encoder wires must be shielded, and firmly fixed to door mounting
frame in order to avoid mechanical damage to the wiring.
• The ground plane of the controller's electronics is electrically connected to the
housing.
Pay special attention to installation of the mains transformer. It is best to install it within
the housing of the service ride switchboard usually found on top of the car. It is also possible
to power the controller from an external DC power supply having appropriate current rating. If
complete electrical isolation of the controller from the rest of the elevator's control system is
required, use the transformer and use potential-free contacts of relays to drive the control
inputs of the controller (see fig. .5A)
Figure .1 shows all external connectors of SDK-500 controller. Connectors of optical
barrier, relay outputs, control inputs and communication interface of RS-485 are located near
the LCD display and keyboard area.

3.3. POWER SUPPLY
Fig. 3.2. Power supply connection of SDK-5 controller
Main power is supplied by a toroidal transformer - minimum 150VA and nominal output
voltage 24VAC.
•It is necessary to protect the transformer primary winding circuit with a 2A fuse.
•Never use transformers having idle secondary voltage higher than 27 VAC
If door operation is required also during mains failure a 24V battery of minimum 1.2Ah
capacity must be connected externally. Use of two standard 12V batteries connected in series
is possible. An automatic battery charger circuitry is a part of the controller board and is
designed to charge battery with 200 mA current, which is sufficient to keep the battery fully
charged, but will not be able to quickly charge fully discharged batteries. If main power supply
fails then LCD backlight and motor will be switched off and SDK-500 will continue operating on
battery. When the battery voltage drops below certain threshold (19V) the controller will shut
down.
Battery connection is not mandatory and the controller can operate normally without it,
however the battery voltage read-out on the LCD will be displayed incorrectly.

User's manual for elevator door controller SDK-500
The motor should be connected to SDK-500 using shielded 2-wire cable. Make sure that
shield is connected properly to GND at one end only. Leaving shield disconnected may cause
excessive EMC noise. See chapter First power-on on page 29 to check the order of wire
connections.
3.5. ENCODER
A) B)
Fig. 3.4. Encoder connection of SDK-5 controller
The controller is designed to work with motors equipped with 5V quadrature encoders,
generating from 150 to 999 pulses per centimetre of door's linear movement. Typically
encoder cables are terminated with a Canon DB-9 connector. The SDK-500 has a DB-9 socket
on board in order to facilitate fast and convenient installation. (Figure .4 A).
CAUTION! Make sure that encoder signal pins match SDK-500 encoder
connector to avoid damage to the controller.
If the encoder cable is not terminated with Canon DB-9 connector, the encoder can be
connected directly to the SDK-500 board's screw terminals as shown in figure .4B.
3.6. CONTROL INPUTS
The SDK-500 controller is equipped with two control inputs provided for compatibility with
different types of elevator controllers. Both inputs or either of them individually can be
activated from the menu of the controller. Connection alternatives are shown below.
Figures .5 A and B shows how to connect open/close control signals to {CLOSE INP.}
and {OPEN INP.} inputs of the SDK-500. The control signals are generated by the main
controller of the elevator. If the elevator control system uses normally-open potential-free
contacts (e.g. relay) to control the doors they can be connected to SDK-500 as shown in fig.
.5A utilising the on-board voltage source of the controller. If the elevator control system uses
voltage outputs to control doors, they can be connected to SDK-500 as shown in fig. .5B.
Make sure that both inputs are activated in the controller's menu.

Fig. 3.5. Connection of the controller while using both inputs
Application of voltage to the {OPEN INP.} input will make SDK-500 start the door
opening procedure. During that, until the door is fully open (until the {OPEN} relay output is
active) removal of the voltage from {OPEN INP.} input will cause the SDK-500 to reverse the
door movement in order to close it. Removal of the voltage from {OPEN INP.} input after the
door has fully opened will not initiate the closing procedure and the door will remain open.
Application of voltage to the {CLOSE INP.} input will make SDK-500 start the door
closing procedure. During that, until the door is fully closed (until the {CLOSED} relay output is
active) removal of the voltage from {CLOSE INP.} input will cause the SDK-500 to reverse the
door movement in order to open it. Removal of the voltage from {CLOSE INP.} input after the
door has fully closed will not initiate the opening procedure and the door will remain closed.
Voltage should not be applied to both control inputs at the same time. If it is, however,
the {CLOSE INP.} signal wins and the SDK-500 will behave as if only voltage was applied to
{CLOSE INP.} input.
Figures .6 A and B shows how to connect the control inputs in systems where only one
output is used by the main elevator controller to control door's opening and closing. Figure
.6A shows how to connect the {OPEN INP.}, input using internal SDK-500 voltage source
and figure .6B shows connection in case of using voltage output on the elevator's main
controller.
A) B)
Fig. 3.6. Connection of the controller while using single {OPEN INP.} input
Make sure that ONLY one input - {OPEN INP.} - is activated in the menu of SDK-500 for
this type of control. In this mode, if the voltage is applied to the {OPEN INP.} input, SDK-500
will open the door and keep it open as long as the voltage remains applied. Removal of the
voltage from the {OPEN INP.} input will make the controller close the door.
Although the SDK-500 can also be controlled using {CLOSE INP.} input only as shown in
fig. .7 A and B. For this purpose only the {CLOSE INP.} input must be activated in the
controller's menu. In this case the application of voltage to {CLOSE INP.} input will make the
