3.A. Lock. speed, range: [ MIN, 20%, 40%, 60%, 80%, 100% ]
Required speed of the door locking should be entered here. MIN = 2.5 cm/s, speed of
door locking for option 100% depends on lock zone length.
3.B. Selflearning [ execute ]
During the „Selflearning" procedure the controller will move the door from the fully open
position to the fully closed position (at low speed). During such a move all pulses are
calculated and stored into the controller memory. Counted pulses represent door width.
There is no need to enter any characteristic points of the door speed profile as
SDK-500
parameters for optimal door functionality. All parameters are set according to
meet regulations.
3.C. Diagnose [ execute ]
It is recommended to execute the „Diagnose" procedure on the new installation or after
door mechanism maintenance.
remember average current value during this operation which will be stored as a reference
value for „Threshold" parameter. During operation dirt and mechanical factors will cause
additional movement resistance which will influence the current value. As the controller is
monitoring current has a chance to detect and signal maintenance need.
3.D. Threshold, range: 0 ÷ 99 [ % ]
This parameter defines permissible percentage by which the average current value may
be exceeded during opening+closing cycle. This threshold value is stored in memory during
door installation or periodic door maintenance visit by the installer. Maintenance value of
current I
can be calculated using formula:
M
where I
AV
If average current value of opening+closing cycle is greater than maintenance value of current
I then present screen of the LCD display will be shown alternately with „Need service"
M
message.
3.E. Pause time, range: 0 ÷ 29 [ s ]
This parameter determines the delay of the automatic closing of the door when opened
manually.
If, during the delay "Pause time", the door will be opened by hand to the width
of more than 5 cm, the engine is switched off and switched back on after
a delay.
3.F. Force reduc. (Force reduction), range: 0 ÷ 99 [ % ]
This parameter determines the percentage reduction in force at the ends of the door.
