Limit Switch
? Limit switch:
The switch is used to accurately stop the gate in the open and closed
positions.
If the gate stops at the opened position when the limit switch is reached, the gate will not
move if it receives open signals.
If the gate stops at the closed position when the limit switch is reached, the gate will not move
if it receives close signals.
Adjust the limit switch (see Fig.8)
Please adjust the close limit prior to the open limit. The close limit adjustment has three steps
which include rough adjusting, fine adjusting and micro adjusting. Once you have set up the
close limit you can follow the same three s teps for setting of the open limit.
l
Rough adjusting: close the gate by using a remote transmitter that has been
programmed into the SKC -500DC operator, stop the gate approximately 30 -40cm before
the gate is fully closed using the pre-programmed transmitter. Making sure the limit cam
hasn’t activated on the limit switch. Once you have stopped the gate adjust the limit cam
until the limit switch is activated. Open the gate so the closed limit switch is de-activated,
the motor can be stopped at any time once t he closed limit has been cleared. Finally
close the gate and ensure that the gate stops at approximately 30-40cm from the
gatepost once the limit switch is reached.
l
Fine adjusting: adjust the limit cam carefully to make the gate approach the closed
position. When the limit cam clicks, the gate can move about 10cm. Repeat this step until
the gate is less than 10cm from the closed position. Also the gate can be manually
closed once released, which will allow the movement of the gate closer to the fully closed
position. Adjust limit cam until limit switch is activated. Open the gate until the closed limit
has been cleared and re close the gate to check that the closed position is less than
10cm from the fully closed position.
Note: If the closed limit adjustment exceeds the gatepost, the gate will auto reverse after
hitting the gatepost.
l
Micro adjusting: after fine adjustment, measure the distances from the gate to the closed
position (for example 6cm), making sure that the limit switch has been activated via th e
limit cam in the closed position. Then turn on the fourth DIP-switch (the last switch) to the
down position. Open the gate using the remote transmitter to allow the closed limit
switch to be cleared and stop the gate at any time using the remote transmitter. Close
the gate again using remote transmitter, the gate will auto stop when the limit switch is
reached. Then with every press of the LEARN button the gate operator will be
programmed to move 1cm past the limit cam. (For example, if there is about 6cm for the
gate to be fully closed, the LEARN button needs to be pressed 6 times, and the LED2
will flash each time the LEARN button is pressed). After this setup is complete, return
DIP -switch 4 to the OFF position (up).
l
After adjusting, you can open the g ate then close the gate and observe whether the gate
has successfully reached the closed position. If the gate does not reach the closed
position by more than 1cm the micro adjusting process can be re-programmed to suit the
desired distance. (
