jumper is fitted.
start signal input (STR)
This input is NO (Normally Open). When it is momentarily closed to ground the opener will
start. If the gate is already moving then momentarily closing the start input to ground will
stop the movement.
Connect a keyed switch or exit request button to this input. While this input is closed to
ground, any auto-closing function is disabled. This input can be connected to a timer to
force the gates open during certain periods of time.
stop signal input (STP)
The Stop input is NC (Normally Closed). Fit a jumper if no switch is used. When this terminal
is not connected to ground, the gate will not operate – it will not open or close until the
terminal is reconnected to ground, and it will only restart once a command is sent through
the Start input, or through a learned wireless remote control. If the gate is moving when this
terminal is momentarily disconnected from ground then the gate will stop moving until the
connection is re-established, and then only when another Start command is received.
pedestrian access signal input (PED)
This NO (Normally Open) input can connect to safety devices such as pressure edges, or
to a switch that enables one wing to open. Activating a safety device will prevent movement
from fully open or fully closed, and will cause movement to reverse while opening. Safety
devices connected to PED have no effect during closing. A switch connected to the PED
terminal will cause only the M1 leaf to open. The factory default setting opens the M1
leaf for 5 seconds, and this can be over-ridden using the Professional Setup routine. The
leaf will close automatically if auto-close is enabled; otherwise another manual command
is required. Normal opening and closing commands take priority over Pedestrian Access
commands. It is also possible to activate Pedestrian Access using a wireless remote control
that has been learned while the CH-RADIO jumper is fitted.
antenna input (ANT)
The centre wire of a 50-ohm co-axial cable should connect to this terminal. An antenna
of 175mm is recommended. Connect the outer braid of the co-axial cable to the ground
terminal. A ground plane greatly improves an antenna’s performance. It should connect
to the end of the co-axial cable’s braided screen. An alternative is to mount the antenna
through a metal plate that is at least as large as the ground plane’s length.
