Introduction - TechWind SDK-500 User Manual

- Once installation is finished all connections should be re-checked.
- Usage of the controller without calibration and without entering proper door
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.
