ALGE PHOTOCELL RLS1n
The ALGE photocell RLS1n is made with most advanced electronic. You can use the reflection
photocell RLS1n for a distance from 1 to 25 Meter. If you need a longer distance than 25
Meters you have to use the type RLS1nd, which consist of a separate transmitter and re-
ceiver photocell.
Principal:
The transmitter of the photocell sends a modulated infrared beam. The receiver controls the
infrared beam and makes an impulse for each interruption.
If transmitter and receiver is built into one case we call it reflection photocell. The infrared
beam is sent to a reflector. The function of the reflector is like a mirror, which reflexes the
beam to the receiver.
The other type of photocell (RLS1nd) has on one side a transmitter and on the other the
receiver. The infrared beam goes direct form the transmitter to the receiver.
Types of Photocells:
RLS1n: Infrared reflection photocell
RLS1nd: Infrared photocell with separate transmitter and receiver
RLS3c: Three-fold-photocell for track and field
Power Supply for the Photocell RLS1n:
+Up to 100 m cable length from the ALGE timing device by a 3-wire cable (this cable
includes the power supply and impulse line).
+Internal Alkaline battery or NiCad battery (data cable with 2 wires, distances of some
Kilometers are possible).
The internal battery supplies the RLS1n for:
Alkaline C-Cell Battery: about 40 hours NiCd C-Cell Rechargeable Battery: about 18 hours
Meter Indication:
about 1/4 in the white field: not adjusted or beam interrupted
green field: adjusted to the reflector and beam is not interrupted

Input of the battery: Press down to open
batterycompartment
Insert the battery:
Input the battery as far as possible into
the battery compartment. When closing
the cover press the battery into the
compartment.
Switch on of internal Battery:
The internal battery of the photocell RLS1n you can switch on with switch (1).
upper position = battery on lower position = battery off
Attention: If you use a battery be carefull that the battery is switched of when you do not use the photocell.
Otherwise the battery will be empty if you need the photocell the next time.
If you use no battery the switch position does not matter.
Adjustment of the Photocell RLS1n:
+Fasten the fastening-bracket for the photocell and reflector at a pole
+Screw the photocell and reflector on the fastening-bracket
+Twist the reflector toward the photocell
+Connect the cable (e.g. 001-10) at the photocell and timing device
+Turn the timing device (and photocell if intern battery) on
+Open the socket joint of the photocell (turn the yellow knob counter-clockwise)
+Aim at the reflector by using the sight on top of the photocell
+The needle of the level meter has to move as far as possible into the green field
+Close the socket joint of the photocell (turn the yellow knob clockwise)
+If you interrupt the infrared beam of the photocell you hear a beep of the timing device.
The needle of the lever moves into the white area.

Weather Cover:
You can move out the weather cover in order to
protect the lens from snow and rain.
When using the RLS1n on a glecier please use
always the weather cover.
Please notice that the sun is not allowed to
shine direct into the lense of the photocell. This
could destroy the photocell.
