CC3820-R RESOLVER TRANSDUCER INFORMATION
A. General
The CC3820R Resolver Transducer is used as a position feedback device where absolute measurement is required. Both single and dual resolver versions are available. The dual resolver unit contains a fine resolver which is geared 64:1 to the coarse resolver enabling greatly increased accuracy and resolution. The CC3820R contains no electronics! It is a rugged electrical device and should be transformer-coupled to the control system to avoid any induced noise via control common. The resolver-to-digital electronics are mounted within the control system enclosure.
B. Installation
For installation instructions referenced the following specification:
Foot Mounts - CC450FM/(FM), CC46FM (46FM), or CC56FM (56FM)
Foot Mounts Alignment Installation Instructions - R102
(MM) Nema 56C Face Mount (Motor Mount) Installation Instructions - R103
(56C) Nema 56C Flange Mount Installation Instructions - R104
(FC) FC Flange Mount with Stub Shaft Installation Instructions - R105
(45P) CC45P Flange Mount Installation Instructions - R106
(46C) CC45C Flange Mount Installation Instructions - R107
Tapered Sleeve Adapter Installation Instructions - R108
For application of special mounting, installation instructions will be provided with shipped sensor.
C. Adjustments
No adjustments are required to install and use the CC3820R Resolver Transducer. Dual units are phased prior to shipment such that, at zero position, excitation on R1, R2 will produce output waveforms on both coarse and fine S1, S3 windings that are exactly in phase at zero degrees.
D. Maintenance
No maintenance is required. Should replacement become necessary, remove the (4) 1/4-20 x 7/8" socket head cap screws as shown in the installation instructions. Insert replacement in the frame's counterbore, and torque the (4) screws 15-19 ft-lbs. This way no alignment is required.
E. Electrical Connections - Reference to outline and connection drawings
Conduit - Remove (4) 10-32 x 5/8" fillister head screws with #10 lock washers and remove the O-Ring Sealed End Cap. Bring cables to resolver terminals through 1/2-14 NPT. Connect wires to terminals. Make sure the end of the resolver and the end cap are clean, and install end cap. Torque screws 20-30 in-lbs.
MS Connector - Solder wires to mating connector. Screw MS connector onto the bulkhead so that approximately two threads remain visible on the bulkhead connector.

CC3820R = Basic (Mill Duty) Design Resolver Transducer
1 = RESOLVER CONFIGURATION
____S = Single = 4096 total counts2 = GEAR RATIO - All gear trains are of anti-backlash design
Gear Down
____Duals available from 1:1 to 100:1 to and including 800:1
Also available are ratios between numbers, for example 2.5:1
X:X = # of input turns to resolver turns. Example: dual 4:1 means for every four turns of the machine shaft the fine resolver will turn once and 4 x 64 = 256 is the # of input turns before the coarse resolver will roll over.
Gear Up
____Duals available from 1:1 to 1:64Also available are ratios between numbers, for example 1:1.5
X:X = # of input turns to resolver turns. Example: dual 1:4 = 1 turn of machine shaft causes four turns of fine resolver will turn four times and 64/4 = 16 is the # of input turns before the Coarse Resolver will roll over.
3 = MOUNTING
____FM = CC450FM Foot MountAlso available various Adapter Plates for interfacing with existing devices, for example Selsyns, and Limit Switches
____DS = Base Plate to replace DS38204 = OUTPUT TERMINATION
____MS = Sealed MS connector with mateCarlen Controls, Inc. warrants its products to be free from defects caused by faulty materials or poor workmanship for a minimum period of one year from the date of shipment from Carlen Controls.
This warranty does not cover defects or damages caused by service or repair performed by anyone other than Carlen Controls. Do not attempt to open covers or housings where fasteners have been sealed.
Carlen Controls’ liability is limited to replacing, repairing or issuing credit at its option, for any products which are returned by the original purchaser during the warranty period. Carlen Controls makes no warranty that its products are fit for the use or purpose to which they may be put by the buyer, whether or not such use or purpose has been disclosed to Carlen Controls in specifications or drawings previously or subsequently provided, or whether or not Carlen Controls’ products are specifically designed and/or manufactured for the buyer’s use or purpose. Carlen Controls’ liability on any claim for loss or damage arising out of the sale, resale or use of any of its products shall in no event exceed the selling price of the unit.
Carlen Controls warranty covers only products manufactured by Carlen Controls. Products used in conjunction with Carlen Controls products but supplied by another manufacturer; such as Inland Motors’ tachometer and Hubbell overspeed switches, are covered by original manufacturer’s warranty.
Return Products Procedure
No products may be returned, whether in warranty or out of warranty, without first obtaining approval from Carlen Controls. Any returned product (s) must be accompanied by a return authorization number. Products must be returned, prepaid, to Carlen Controls (no COD or Collect Freight accepted). The status of any product returned later than (3) days after the issuance of a return authorization number will be subject to review.
Returned Product Warranty Determination
After Carlen Controls’ examination, warranty or out-of-warranty status will be determined. If upon examination a warranted defect exists, then the product (s) will be repaired at no charge and shipped, prepaid, back to the buyer.
Return Product Non-Warranty Determination
After Carlen Controls’ examination, the buyer shall be notified of the repair cost. At such time the buyer must issue a valid purchase order to cover the cost of the repair and freight, or authorize the product (s) to be shipped back as is, at the buyer’s expense. Failure to obtain a purchase order number or approval within (30) days of the notification will result in the product(s) being returned as is, at the buyer’s expense.
Rush Service
At times, the buyer may desire to expedite a repair. Regardless of warranty or out-of-warranty status, the buyer must issue a valid purchase order to cover the added rush cost service. Rush service is subject to Carlen Controls’ approval.
