What's New?

April 30, 2013 – May 2, 2013

Vincent Associates®, the manufacturer of UNIBLITZ® Electronic Shutters and Shutter Systems, will exhibit their line of UNIBLITZ® shutters at SPIE’s Defense, Security & Sensing 2013.

General Specifications

The following provides additional information on the Electronic Synchronization System on our LS, VS, CS and XRS type shutter devices and our Manufacturer's Warranty. Please note, the synchronization system available on the NS type devices, is described separately.

The Electronic Synchronization System provides a feedback signal after the shutter transfers to the open state. The system incorporates an infrared emitting diode, an infrared sensitive detecting transistor, and an interrupting vane. The vane is attached to the shutter so as to block the light path between the emitter and detector in the closed position. When the shutter transfers to the 80% open position, the vane is removed from the infrared light path, allowing the emitter to switch the detector to the active state. See Figure #3 for the CS25 and CS35 schematic with the Electronic Synchronization system. This system uses a similar activation flag attached to the mechanism, which triggers a reflective emitter/detector device. See Figure #4 for the sync schematic of the Electronic Synchronization system for a shutter equipped with a 5-pin connector (exception – CS25 and CS35 – as indicated, these devices have a specially designed synchronization system – see Figure #3). See Figure #5 for the CS25/CS35 schematic without the Electronic Synchronization. See figure #6 for the schematic of all other shutter models with Electronic Synchronization. See Figure #7 for the schematic of all other shutter models without Electronic Synchronization. Please note that the CS90HS shutter device will contain two 24 ohm coils wired in parallel to provide a total resistance of 12 ohms. All other standard devices (LS,VS, and CS type) devices contain a single 12 ohm coil. This allows the CS90HS to be driven by all standard UNIBLITZ® drive systems.

The Synchronization system for the NS type devices incorporates a small magnet mounted to the driving mechanism and a Hall Effect sensor. When the device achieves approximately 80% of full open, the magnet causes the Hall Effect sensor to change state producing a signal to indicate that the shutter has switched to the active state. See Figure #8 for the NS shutter schematic which incorporates the Electronic Synchronization system. See Figure #9 for NS shutter models without Electronic Synchronization.

Support circuitry for the Electronic Synchronization System is built into the VCM, VDM and VMM type drive equipment. See the Timing section's Figure 1 for typical synchronization output waveform in the timing specifications.

Warranty

LIMITED PRODUCT WARRANTY: All Products manufactured by VINCENT ASSOCIATES® (MANUFACTURER) are warranted to meet published specifications and to be free of defects in materials and workmanship as defined in the specifications for 365 days - one year - (WARRANTY PERIOD) from the date of original shipment of the product. DSS series shutters are additionally warranted to achieve two million cycles within the WARRANTY PERIOD (as defined in the CYCLE WARRANTY CRITERION). MANUFACTURER will, at its own option within the WARRANTY PERIOD, repair or replace without charge any listed item discovered to be defective excepting transportation charges. Burned out or otherwise damaged actuator coils are not covered under this warranty. Any defective product returned to the MANUFACTURER must follow the RETURN MATERIAL AUTHORIZATION PROCEDURE as defined below. This warranty does not extend to cover damage resulting from alteration, misuse, negligence, abuse, normal wear and tear, or accident. The MANUFACTURER will consider the return of unused equipment if returned within 30 days from the original date of shipment, subject to a 20% restocking charge. This offer does not apply to used or damaged equipment. This warranty extends only to the original purchase and is not available to any third party, including any purchaser assemblies or other Products of which the goods may become component equipment.

CYCLE WARRANTY CRITERION: One "cycle" is considered one open and one closure of the shutter. DSS Shutter must be operated with the ED12DSS driver or equivalent H-Bridge type shutter driver circuit at +10.7VDC across the actuator coil for the specified duration. DSS Shutter must be operated within the defined environmental, electrical and mechanical specifications as listed on the device's data sheet. After one year (WARRANTY PERIOD), the cycle warranty is null and void. If returned, the device must be accompanied by a written statement indicating the approximate number of cycles contained on the device, include all parameters to which the shutter was operated and follow the RETURN MATERIAL AUTHORIZATION PROCEDURE as defined below.

RETURN MATERIAL AUTHORIZATION PROCEDURE: MANUFACTURER will only accept returned Products from customers that have obtained an RMA (Return Material Authorization) number from the MANUFACTURER. The customer must also include an itemized statement of defect(s). The Product will then be evaluated per the MANUFACTURER'S standard repair guidelines. Any Product which has been returned to the MANUFACTURER but which is found to meet the applicable specifications and not defective in materials and workmanship shall be subject to the MANUFACTURER's standard evaluation charge. The MANUFACTURER assumes no liability for customer returned material.

LIMIT OF LIABILITY: The buyer's exclusive remedy and the limit of MANUFACTURER'S liability for any loss whatsoever shall not exceed the purchase price paid by the buyer for the goods to which a claim is made. MANUFACTURER does not give any implied warranties of merchantability, fitness for a particular purpose, or of any other nature in connection with the sale of any Products.
