they must be series connected
If more photocell pairs are connected, RX and TX units
of the safety set should be cross installed
"S1 Edge" OPENING/CLOSING PHASE SAFETY DEVICES
It is possible to connect devices (e.g. photocells or edges) with
nor- mally closed (NC) contact or 8K2 resistive edges to the "S1
Edge" input (terminal 9-10).
The factory wire bridge connected to PHO2 must be removed
when using this input.
These devices intervene while the door is moving, in particular:
- with the closed door they lock opening commands.
- with the opened door they lock closing commands.
- during the closing phase they command a brief inversion
- during the opening phase they command a brief inversion
Figure 38 show examples "PHR00" photocell connections.
10.6 – 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.
10.7 – 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
Paragraph 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 1 STEP is set to OFF and dip 2 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.
10.8 – AEREAL
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 NiceHome flashing lights range).
If an external antenna is connected, the series connected
wire must be disconnected.
