open the gate, see
Verify open direction
section. Wait until the gate travels the distance
that you desire (the distance range is 0.3m~2.5m or wait for 3~10 sec.). Then press the same
button to stop the gate, wait until the gate close automatically (45 sec.). Stop the gate by
pressing the same button or the gate will stop at its closed position automatically if the limit
switch is reached. Then move the first and the second switches of SW (DIP-switch) to OFF
position (up) immediately. Thus ‘the width of pedestrian mode’ has been reserved, ‘the auto-
close function of pedestrian mode’ has been cancelled. (Note: the new width of pedestrian
mode has been re-programmed in the device and replaced the original width.)
If you open the gate with button 4, the gate will stop at the expected position that you have
set, but the gate will not close automatically.
External Interfaces
Keypad/ Button Switch
The SKC-600DC is equipped with an interface for an external switch or keypad. The interface
type is a NO (Normally Open) momentary switch to ground. To activate the opener, the
keypad or other device must short the ‘0’ and ‘DI’ terminal momentarily on Box JX2. This type
of switch is very common. To install the device, attach one lead of your keypad to the ‘DI’
terminal and the other to the ‘0’ terminal. The keypad will function in single channel mode just
like the RF remote. If the gate is closed, then activating the keypad will open the gate. If the
gate is open, then activating the keypad will close the gate. If the gate is moving, then
activating the keypad will stop the gate. If your keypad requires DC power, then you can use
the 12 or 5 terminals and the ‘0’ terminal for ground as required by your device. See diagram
3. Consult your device manufacturer’s documentation for details. The keypad device can be
obtained through your dealer. To find a dealer, go to www.gatekeeperltd.com/dealers
Loop detector
A magnetic loop detector detects vehicles that are within proximity to the gate. A magnetic
loop detector can be used to open the gate when a car pulls up either from the inside or the
outside depending on which side of the gate you install it. A magnetic loop is usually buried
under the ground, and the wires run to the gate opener control board. Magnetic loops usually
require DC power, using the + and – DC terminals. They provide a normally open
momentary switch interface to the control board and its ground or common interface. Wire
the magnetic loop’s DC + wire to the 12 terminal on block JX3, wire the power common or
ground to COM. Wire the magnetic loop’s normally open trigger wire to terminal BI and the
normally open ground or common to COM both on block JX3. The terminal BI is a “free open”
terminal. This means that it will only open the gate, if the gate is already opening, it will have
no effect, if the gate is closing, it will override and open the gate, but triggering the terminal BI
will never close the gate. Consult your device manufacturer’s documentation for details. See
Figure 4 for a diagram of external interface connections. The Loop Detector device can be
obtained through your dealer. To find a dealer, go to www.gatekeeperltd.com/dealers
Safe guard (Infrared device or Photocell)
It is recommended that the installer purchase and install infrared photocells for additional
safety. Photocells work by inhibiting the movement of the gate if the beam is broken. Infrared
safety devices may be required by law in some areas. If the infrared beam is broken during
closing, the gates will reverse and open immediately. During opening, the beeper will ring.
Infrared photocells come in active and passive varieties. Active photocells require power on
both sides of the driveway, whereas passive photocells employ a reflector plate so that power
is only required on one side of the driveway. Most photocells will provide DC power input
wires + and -, and 2 normally closed switch wires. To install the photocell, attach the DC
