OVERVIEW
The CS90 is the third release in the new UNIBLITZ®CS series. The small form factor allows a 90 mm aperture to beinstalled into applications not presently accessible with existing UNIBLITZ®VS series shutters. As with the CS45 and CS65, the CS90 has beendesigned to provide accurate, repeatable exposures for a wide varietyof applications. The small form factor allows a 90 mm aperture to beinstalled into a seven-inch diameter housing. To increase the unit’s flexibility, the shutter can be supplied in an un-housed version for OEM applications or in situations inaccessible to most shutters due to
spatial limitations.
The device incorporates a dual actuator system. This dualactuator system incorporates the drive circuit for the auxiliary actuator onto the device, allowing the shutter to be controlled with existing VMM and VCM UNIBLITZ®drive units only. Please note that the 122-BP will not operate the CS90at this time. (For more information regarding the use of OEM drivers - either UNIBLITZ® or of your own design, please contact technical support.) As an option, the shutter can be equipped the electronic synchronization system.
When gating high intensity light sources, the CS90 can be equipped with polished stainless steel reflective blades. This option protects the shutter blades from the light source’s damaging effects by reflecting the energy away from the blade surface. Look for future availability of “Z” (AlSiO) and “ZM” (AlMgF2) coated blades in this device.
To further enhance the flexibility of the CS90; an optional #103 mounting ring is available to allow the shutter to be easily mounted in many non-specific applications. Additional information regarding the #103 mounting ring can be found in the specific datasheets entitled “MICROSCOPE, VIDEO, or UNIVERSAL MOUNTING SYSTEMS” oronline under “products”, “Mounting Systems”.

When operating this device without UNIBLITZ® drive equipment, (i.e. using adriver of your own design, etc.) please request and review the CS90 Shutter Electrical Configuration Layout. Please note the 122-BP driver should not be used to operate the CS90 at this time. Only VMM and VCMtype drivers are recommended to operate the CS90.

The question regarding enhancement of shutter speed with the application of user supplied lubricants has been repeatedly asked. It is our experience that lubricating the shutter blades will actually slow the shutter down and eventually render the shutter inoperable. UNDER NO CIRCUMSTANCES SHOULD ANY TYPE OF LUBRICANT BE APPLIED TO THE SHUTTERBLADE AREA. DO NOT USE THE 122-BP OEM CONTROLLER TO DRIVE THE CS90. PLEASE CONTACT TECHNICAL SUPPORT BEFORE USING ANY OEM DRIVE CIRCUIT.
Unhoused Style
The CS90un-housed style is the basic configuration of this device and is best suited for OEM applications. Mounting can be accomplished through six0-80 (flat head required) clearance holes located around the unit’s perimeter on a 6.670 inch diameter bolt circle. These holes, as indicated, are 60 degrees apart. Unless otherwise specified, this standard unit is terminated to a 7-pin male connector through a 7-wire six-inch cable assembly. (The six 2-56 holes are not recommended formounting due to the potential for interference with the shutter’s sixblades.) DUE TO THE ACTUATOR CONFIGURATION AND THE ON BOARD AUXDRIVER, DO NOT USE THE 122-BP CONTROLLER TO OPERATE THE CS90. PLEASE CONTACT OUR TECHNICAL SUPPORT STAFF WHEN USING ANY OEM DRIVER DESIGN.
Housed Style
The CS90#3 housing style allows a number of mounting configurations. A ¼-20threaded hole is provided for post mounting. The 4.00inch x 40TPIexternal thread located on the rear side, and the specific mountingholes located on the front side (see Figure #2 and Figure #3) can beinterfaced directly into your application or fitted with a variety ofuser specific mounting options. For the CS90, the #103 Mounting Ring isa mounting option available that simplifies mounting the housed styleonto a flat surface. Additional information regarding the #103 mountingring can be found in the specific data sheet entitled “MICROSCOPE &VIDEO MOUNTING SYSTEMS” or on-line under “products”, “MountingSystems”. The unit terminates with a 7-pin male connector asillustrated. DUE TO THE ACTUATOR CONFIGURATION AND THE ON BOARD AUXDRIVER, DO NOT USE THE 122-BP CONTROLLER TO OPERATE THE CS90. PLEASECONTACT OUR TECHNICAL SUPPORT STAFF WHEN USING ANY OEM DRIVER DESIGN.
