Description
The infrared photocells ERONE mod. SEF2420AV are a security device designed to
the protection of areas in which are operating automatic closing systems.
The alluminium covers allows an antivandalic installation.
The product is composed by a couple of adjustable optic infrared devices TX and
RX, operating at 880 nm wavelength.
The rated range is 20 mt under all whether conditions ( rain, fog, dust ).
The reduced dimensions allow an easy installation procedure on any type of
structure.
The adjustable optic both horizontally ( ±40° ) and vertically ( ±15° ) allows the
best alignment in any installation condition.

Recommended cable cross-section:
- transmitter photocells 2 x 0,6 mm
- receiver photocells 4 x 0,6 mm
Connect the output contact to the terminals C eand NO for a normally open
contact or C and NC for a normally closed contact ( Fig. 7 ).
Alignment
Align the transmitter and the receiver so that the beam is established and the red
led (LR) goes off ( Fig. 6 and Fig. 8 ).
Sensitivity adjustment
If the distance between the transmitter and the receiver is less than 5 metres remove
the bridge on the transmitter ( Fig. 12 ).
Adjust the sensitivity with the trimmer on the receiver ( Fig. 8 ).
The optimum detection is obtained when a voltage of 3,2 Vdc is read across
terminals T and P ( read the voltage with a voltmeter - Fig. 9).
On the transmitter
The green led is ON when the transmitter is powered.
On the receiver
- The green led is ON when the receiver is powered ( Fig. 11 );
- The red led is ON when the beam is not established (Fig. 11).
