If more photocell pairs are connected, RX and TX units of
the safety set should be cross installed (see Fig. 38c).

24V
accessories’ power
supply
TERMINALS: 8-5, 10-5.
Nominal voltage 24V
, max. 250mA, output for powering
external accessories as photocells, radio receivers, etc.
Real voltage output can be greater than nominal value, check the
compatibility of external accessories.

Wired commands
TERMINALS: 6-7-8-10.
Inputs for the start, stop wired commands can be customized to
open, stop (Paragraph 15.1).
They can be locked to prevent tampering with the system (Paragraph
15.2).
START CONTACT
The “START” input (terminals 7-8) is a normally open gate activa- tion
command by wire.
The activation method is set up by dip switches 1 and 2 - see Par-
agraph 4.1.
This input is a voltage free (dry contact) only. Connecting power to
this input will void warranty.
TIMER FUNCTION: if START contact is kept closed (for in-
stance through a timer-controlled or bistable relay), control
unit opens the gate and leaves the gate opened. The auto-
mation does not accept closing commands (neither automatic
nor wired) until START contact is reopened.
In this mode, dip switch 3 STEP is set to OFF and dip 4 AUTO
to ON to ensure that the gate never remains locked open.
If multiple START contacts are connected, connect the
contacts in parallel.
If START contact is kept closed during the control unit
starting after a blackout, the gate will immediately execute
the start command.
STOP CONTACT
The “STOP” input (terminals 6-8) is for immediately stopping
and locking any movement of the gate.
This input is a normally closed and voltage free (dry contact)
only. Connecting power to this input will void warranty.
To restore operation this contact must be closed.

Antenna
TERMINALS: 13-14.
Antenna terminal for transmitter signal reception. A wire is factory
connected to this terminal.
For extending the reception range, an external antenna can be con-
nected (present in the King Gates flashing lights range).
If an external antenna is connected, the series connected wire
must be disconnected.
