General Information

The Barlo Safety Beam consists of 4 basic components: All assemblies are manufactured with the highest grade of components available to assure reliable operation, even in harsh environmental conditions.

High Voltage Power Supply (12096)- this is a 120VAC to 700VDC high-energy capacitive-discharge supply that is mounted on the top of the visor assembly. The components are hand soldered and then it is encapsulated in a two-part, temperature stable, epoxy.
Trigger Circuit (12095), This is a 22-24KV-trigger source that is mounted inside the visor assembly.
Traffic Signal Housing; we use the best available traffic signal housing complete with colored and clear lenses.
Flash Tube (12093), We have the flash tube manufactured specifically for this operation. The glass tube is approx. 23cm in length and 1cm in diameter filled with a Xenon Gas mixture formulated to produce a long life - bright flash combination.
Theory of operation: The High Voltage Power Supply charges its capacitors up to approximately 650 to 750VDC, applying it to the ends of the flash tube and to the triggering circuit. The trigger then produces a 22-24KV, 35ms pulse to the wrap wire on the outside of the flash tube causing the xenon gas to conduct producing the brilliant flash, the power supply then recharges and repeats the process at the frequency specified for the operation.

Operating Instructions

Unpacking
The Barlo Safety Beam units are carefully manufactured, packed and shipped in specially designed cartons to eliminate as much breakage as possible. However, a high voltage device such as this can develop "leaks" that can lead to malfunctions and component failure if not corrected prior to installing the unit in the field. The following procedures must be followed to avoid time consuming and costly repairs.

1. Carefully open and remove the Barlo light from the shipping carton and place all packing material back in the box and store for future use.

WARRANTY CONSIDERATIONS CAN NOT BE GIVEN TO ANY EQUIPMENT THAT IS NOT RETURNED PROPERLY PACKED IN THE ORIGINAL CONTAINER.

2. Perform a visual inspection of the unit for freight related damage to the box and the glass components of the Barlo. Visually inspect the Xenon flash tube for damage. Make absolutely sure the trigger wrap (Red wire) is not touching the negative (Brown) feed to the flash tube. This sometimes occurs when the Barlo is dropped during shipping.

ALL DAMAGE MUST BE REPORTED IMMEDIATELY TO THE CARRIER FOR INSPECTORS TO SUBMIT CLAIM.

3. Bench Test the Barlo. Screw in an incandescent bulb into the socket and connect 135VAC to the terminal block located in the inside back wall of the signal housing.

ALLOW THE UNIT TO FLASH FOR A PERIOD OF AT LEAST 12 HOURS PRIOR TO INSTALLING IT IN THE FIELD. If the flash tube suffered any microscopic cracks during shipping, this bench test will reveal it, saving the installer from a return trip to replace a broken tube.

 

Trouble Shooting
If the strobe unit fails to operate, follow these procedures to isolate the cause.

ONLY QUALIFIED PERSONEL SHOULD ATTEMPT TO SERVICE THIS DEVICE.

CAUTION: This power supply retains 500 to 800 VDC for long periods of time AFTER the AC power is removed. NEVER touch the xenon flash tube without discharging the power supply.

1. Check the supply voltage

There should be approximately 135VAC input to the strobe power supply. The incandescent bulb should illuminate.

2. Remove Colored Lens

Carefully remove the colored lens. Connect a 0-1000 Volt DC Meter to each end of the Xenon Flash Tube, Connect the - to the brown wire and the + to the blue wire (never touch the red wire (22 - 24KVDC) or try to take a voltage reading from this wire) apply AC power. The voltage reading should be between 600 and 800 VDC. If it is not replace the power supply with a new one part#12096.

3. Listen for a faint "clicking "

If the power supply is within the limits described in step 2, listen for a faint "clicking " sound coming from the flash tube area. This sound is the trigger pulse, if you can hear it the flash tube is likely defective, if you can not hear it, the trigger is likely to be the problem. To discharge the power supply prior to removing the flash tube, remove AC power from the unit, disconnect the terminals to the incandescent light bulb from the terminal block in the back of the housing. Touch each end of the Xenon flash tube with one of the wires from the incandescent bulb (there will be a bright momentary flash of the incandescent bulb as it discharges. Use your voltmeter to check for the presence of any voltage at the ends of the flash tube. If it has discharged reconnect the incandescent wires on the terminal block, If not repeat operation or connect a 140 Ohm 5 watt resistor to each end of the xenon tube. If the Barlo Light needs further evaluation it should be returned to your local distributor or Elliott Equipment Corp. for repairs.
