ALGE-Timing P1a
The ALGE-Timing P1a is a photocell device designed for use in ice speed skating. It consists of a transmitter (P1a-TXd) and a receiver (P1a-RX) that communicate via modulated infrared beam. The transmitter sends the beam, and the receiver detects any interruptions, generating an impulse for each interruption.
Capabilities:
- Adjustable range: 2 to 25 meters.
- Fast reaction time: 300 µs, fixed at 2 ms.
- Powered by a rechargeable 12VDC battery for the transmitter and an external 5VDC power supply for the receiver.
- Simple adjustment: Align the transmitter and receiver approximately, then adjust until the receiver's indicator shows green, indicating proper alignment and no beam interruption.

Photocell P1a-TXd / RX
The ALGE photocell RLS1n is made with most advanced electronic and for the employment
on ice (Speed Skating).
Principal:
The transmitter (P1a-TXd) of the photocell sends a modulated infrared beam. The receiver
(P1a-RX) controls the infrared beam and makes an impulse for each interruption.
Power supply of the photocells P1a-TXd / RX:
P1a-TXd:
Internal Accu which can be load by a PS12A.
Aproxx. 16h working time with fully loaded accus.
P1a-RX:
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).
Instrument reading P1a-RX:
about 1/4 in the white field: not adjusted or beam interrupted
green field: adjusted to the reflector and beam is not interrupted

Photocell P1a-TXd / RX
Adjustement of the Photocell:
Place the P1a-TXd in the middle and the P1a-RX on both sides of the course
(picture on side 2) and align approximately.
Connect the P1a-RX with the Timer and switch it on. Also press the button of the P1a-TXd to
switch it on.
To adjust the photocells correctly, move it so long till the pointer is on the green field of the
instrument and it doesn´t oscillates
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.
