OPERATION INSTRUCTIONS A w Set up and switch on ONE transmitter with 10 in LOW mode Use HIGH only when necessary Switch on the photocells 2 on IMPULSE mode standard use or DIRECT mode Depending on the sport to be timed and the application it may be necessary select either direct trigger output to the timer or to have a period of time in which the photocells output pulse for timing is blocked Impulse between the impulse generated and the NEXT impulse sent The most popular method is to use Impulse settings so that you can adjust using the lower knob the Impulse signal width from 0 01 seconds to 2 4 seconds Direct ties the output trigger directly to the photocell sensor The impulse length is thus not adjustable and is always a function of how long the photocell signal is obstructed This can be very useful for determining out of alignment status or how many objects pass in sequence in front of the cells Watch very carefully for BOTH the BATT and OSC Oscillator Syncro Lock LEDs to illuminate briefly and then immediately go out This is the NORMAL start up condition and it is important to see it happen this way If the Transmitter OSC or BATT lights don t flash momentarily at power up or remain on or flash after power up remedial action is required as described below Battery Check When you switch on the photocell the LED 3 BATT illuminates briefly and goes2. looking for a center point of best aim Take your time and work back and forth if necessary using the two receivers and ONE transmitter at first Fine tune this alignment on LOW power until one transmitter is covering the TWO receivers perfectly gt Go back to the receivers and aim them again by using the sighting groove 1 Once roughly aimed carefully move each receiver to zero in on the transmitter signal using the SIGNAL LED condition as your only guide Once the SIGNAL LED starts responding to aiming avoid using the housing aS a rough guide and now use the SIGNAL LED reaction exclusively to fine tune the aim point You are in proper alignment when LED 4 SIGNAL is firmly and solidly off not even flickering and stays off even if you move the receiver photocell slightly the tap test gt Return to the transmit side and now finally fine tune the aim of the transmitter to the receivers with the aid of the red LED as seen through the lower lens of the receiver This luminous indicator placed under the receiving lens allows you to very accurately center the alignment of the transmitter on the receiver from across the line and is a huge assistance to assuring correct installation It should be possible on low power at 40m to easily find the solid centre point of the aim of one transmitter to both receivers gt Turn OFF the first transmitter once aligned and repeat the same process with the second transmit

LOW position and up to 80 m 260 ft in HIGH position PHYSICAL SET UP Transmitters are on one side receivers are on the other Do not set up in an opposite manner We recommend the use of 4 separate support posts one for each unit so that a disturbance or problem with on post will not case a failure of the entire A B concept DO NOT attempt to isolate the two sets The whole idea is to allow either or of the transmitters to cover the two receivers on the opposite side In such a set up the ohysical redundancy of the two receivers remains completely functional and accurate even if one of the transmitters should fail RECOMMENDED USE e The photocells must be placed within close vertical proximity to each other when used at the same timing line in order to avoid large differences in triggering times e For added timing system dependability use these photocells with our HL 553 impulse distributor and optocoupler e When the photocells are mounted connect both transmitters with the dedicated cable on the SYNCHRO 3 pins plug e Toline up correctly these double photocells line up first the upper transmitter with the upper receiver The bottom photocells are OFF e When the alignment is correct turns OFF the upper photocells and ON the bottom one and line up them correctly e Then switch ON again the upper photocells and test them masking one of the transmitter and after the other one TAGHeuer Timing Page 3 12

TAG Us TAGHeuer PROFESSIONAL TIMING HL2 33 PHOTOCELL USER MANUAL Version 11 2013 w TAGHeuer Timing Page 1 12 DESCRIPTION The Infra Red photocell HL2 33 set is composed of two transmitters HL2 33E and two receivers HL2 33R There are 4 matched units in each set allowing system A and B coverage of a timing line All units are internally battery powered only 2x 3 AA type per unit Adjustment of the output impulse time blocking after initial triggering is available on the receivers This photocell satisfies the most exacting requirements of sports timing and is normally used at finish lines where parallel redundancy of two sets of independent sensors is needed for A and B timing systems The sets of photocells 4 units in all are matched and tuned to work with each other and should be kept as a set Do not mix units with other sets since unwanted interference from the two sources of coded transmitters may result Any repairs and adjustments MUST be done as a matched set of 4 units The theory of operation is to provide two sets of photocells that are fail operational Both transmitters Tx are placed on one side of the finish together the receivers Rx are likewise placed together on the opposite side from the transceiver The transmitters should ultimately be aimed to cover BOTH receivers at the same time In this manner a failure or misalignment of one transmitter will still allow both receivers to operate norma
