Maintenance Although this photocell is built to work in hard conditions, we
advise you to open sometimes the aluminium cover and to let it
dry when the photocell has been exposed to humidity.
Special Note In case you use an external power supply, we advise you to
place, in any case, 3 internal batteries. These will insure the
functionning of the photocell in case of current cut off or falling
voltage.

HL 2-35 PHOTOCELL
USER’S MANUAL
DESCRIPTION
The infra-red photocell HL 2-35 is composed of one transmitter (HL 2-35E) and one receiver (HL 2-
35R) with internal or external power supply and adjustment of duration of output impulse. This photocell
offers exceptional quality for the price, satisfying the most exacting requirements of sports timing.
Principle
Transmitter Receiver
The above photocell works perfectly with a distance between transmitter and receiver of up to 40 m.
(130 ft.) in "LOW" position and up to 80 m (260 ft) in "HIGH" position.
OPERATION INSTRUCTIONS
Switch on the transmitter with ➁in LOW or HIGH mode.
Switch on the receiver with ➁.
a) Battery check
When you switch on the photocell, the LED ➂"BATT" illuminates briefly and goes out.
INew Batteries ➂does not illuminate
II Used batteries ➂flashes slowly (once every 2 sec.).
The batteries insure at least 30 hours of functioning at 20° C.
III Flat batteries ➂flashes rapidly (once every sec.).
The batteries must be replaced. If this arises during the
timekeeping the batteries will insure at least 6 hours of
functioning at 20° C.
WARNING Battery (hours of utilisation) is very much reduced under 0° C and
depends on their quality. We strongly recommend to use new
batteries as soon as LED ➂flashes.
b) Lining up the photocell
When you switch on the receiver, the LED "SIGNAL" ➃illuminates as long as the transmitter is
not lined up with the transmitter.
First set up the transmitter on the receiver by using the sighting groove ➀.
Then aim the receiver by using the sighting groove ➀.You are in alignment when LED ➃
"SIGNAL" is switched off and stays so even if you move slightly the photocell.
A luminous indicator placed under the receiving lense allows you to align accurately the
transmitter on the receiver.
Transmitter and receiver must be steadily fixed on supports ref. HL4-3 or on tripods.
When you cut the beam between the transmitter and receiver, the LED "SIGNAL" ➃comes on.
The impulse is given at the output connections ➆.
c) Adjusting length of impulse ➅
➅➅
➅
Depending on the sport to be timed, it may be necessary to have a period of time in which the
apparatus is blocked between the impulses in order to eliminate interference caused by the
moving body.
Min. adjustment : Duration of impulse 1/100 sec.
Max. adjustment : Duration of impulse 2 sec.
d) Output jacks ➆

Open collector outlet - working contact (short circuit between black and green terminals)
Green terminal : Impulse
Black terminal : Ground
e) Changing the batteries
Remove the screw underneath the case. Slide the electronic unit out of the case. Change the 3
batteries observing the polarities marked on the bottom. Be sure to use good quality Alcaline type
1.5 volt batteries (UCAR Energizer E-91 e.g.). Put the electronic unit back in the case and do up
the screw carefully.
