accessory power output (VA)
The maximum allowable combined load on the VA and TXF terminals is 150 mA.
Accessories in excess of this limit must be powered directly from the battery.
NOTE
Power the transmitting photocell from the TXF output if the TEST 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 gate open during certain periods of time.
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 the gate 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 gate to open. The factory default
setting opens the gate for 5 seconds, and this can be over-ridden using the Professional
Setup routine. The gate 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.
stop signal input (STP)
The Stop input is NC (Normally Closed). Fit a jumper if a stop switch is not 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 another Start command is received.
opening and closing limit switch inputs (FOP, FCL)
Connect to the internal limit switches. .
antenna input (ANT)
The centre wire of a 50-ohm coaxial cable should connect to this terminal. An antenna of
175mm is recommended. Connect the coaxial cable braid to the ground terminal.
A ground plane greatly improves an antenna’s performance. It should connect to the end of
the coaxial 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.
