Description Of The Device; Led Signals - V2 SENSIVA-WL Manual De Instrucciones

DESCRIPTION OF THE DEVICE

The photocell SENSIVA-WL consists of a battery powered
transmitter and a receiver that is powered by the control unit.
m
WARNING: It is not advisable to use photocells with
low voltage motors and inverter motors
Features:
• 2 batteries included with the device
• Adjustable up to 180° on the horizontal axis and 30° on the
vertical axis
• Possibility to connect a resistive or traditional safety edge on
the transmitter: when the edge activates, the transmitter stops
the transmission
• Ability to set two different transmission codes to
simultaneously use two pairs of photocells without mutual
interference
• Automatic signal detection slow down in the event of snow to
avoid undesired activations caused by the fall of the flakes
• Maximum range adjustment on two levels
• Led to simplify the tuning of the system
• Led to indicate when the battery is low
WALL INSTALLATION (Fig.1)
For correct installation, follow the instructions below very
carefully:
• Decide where the photocells are to be installed, taking into
account the need for the photocells to be fixed on a flat, linear
surface.
m
PLEASE NOTE: position the photocells so as to avoid
the receiver RX facing into the sun.
m
ATTENTION: the minimum distance between the
transmitter and the receiver must be over 1 metre.
• Decide where to place the channels for the power supply
cables.
• Open the photocell casing and use the base A to mark out the
positions of the fixing holes.
• Fix the base using the gasket F.
• Make the electrical connections.
• Insert the batteries in the battery compartment of the
transmitter.

LED SIGNALS

TRANSMITTER
The red led starts to flash when the battery begins to be low.
Normally it is turned off.
RECEIVER
The red led is used to perform the tuning of the system, indicating
the quality of the signal received from the transmitter.
DIP-SWITCHES AND JUMPERS (Fig. 3)
The dip-switches and jumpers on the electronic circuits of the
photocells are used to set the operation of the system.
TRANSMITTER (TX)
DIP-SWITCH 1 - ON
DIP-SWITCH 1 - OFF
DIP-SWITCH 2 - ON
DIP-SWITCH 2 - OFF
DIP-SWITCH 3
DIP-SWITCH 4 - ON
DIP-SWITCH 4 - OFF
NOTE: To reduce consumption and prolong battery life, it is
recommended to set dip-switch 4 correctly.
RECEIVER (RX)
DIP-SWITCH 1 - 2 - 4
DIP-SWITCH 3
JUMPER J2

Safety edge input enabled (3-4)
Safety edge input disabled
8K2 resistive edge
Traditional edge with N.C. contact
Transmission code: by setting the DIP
to ON or OFF the TX transmits two
different codes.
TX and RX of the same pair must have
the same setting.
Two pairs in the same installation
must have different settings to avoid
mutual interference
- Range from 10 to 20 m
- Consumption = 100 µA
- Autonomy = 1.5 years
- Range from 5 to 10 m
- Consumption = 30 µA
- Autonomy = 4 years
Keep on OFF
Transmission code: by setting the DIP
to ON or OFF the TX transmits two
different codes.
TX and RX of the same pair must have
the same setting.
Two pairs in the same installation
must have different settings to avoid
mutual interference
Position A - relay output with normally
closed contact
Position B - relay output with normally
open contact
