Application of voltage to the {OPEN INP.} input will make
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 3.6 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
3.6A shows how to connect the {OPEN INP.} , input using internal SDK-500 voltage source
and figure 3.6B shows connection in case of using voltage output on the elevator's main
controller.

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. 3.7 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
