Page 6: General Overview
This situation requires calculation of the regulator pressure based on the process equipment weight and AFD orientation. To monitor the Carriage position the AFD82 must be connected to a DC power source and an analog input device through a PushCorp high-flex cable. - Page 7 AFD82 Manual ORP, equipment, then the brackets must be removed and the problem corrected. PushCorp, Inc. can design and fabricate brackets to user supplied specifications as an option. Figure 1: Carriage bolt hole pattern The bolt pattern on the Carriage has been designed to facilitate process equipment installation.

Page 8: Mounting The Afd82
Mounting Bracket is supplied. Adapter plates or "quick-change" attachments can be used as well for mounting. The AFD82 has (2) two 4mm dowel pins pressed into the base for location and alignment of the cover and Mounting Bracket. -
Page 9: Mounting The Afd80-1 Vertical And Afd80-2 Horizontal
The AFD80-1 and AFD80-2 are supplied with a standard Mounting Bracket shown in Figure 4. A minimum of (3) three holes should be utilized to secure the Mounting Bracket to the robot mounting flange.

(4) Four M8x1.25 Socket Head Cap Screws are used to attach the Mounting Bracket to the AFD82 force devices. Once the Mounting Bracket is removed, mounting holes may be placed anywhere within the crosshatched area shown in Figure 4. -
Page 11: Maximum Carriage Load Calculations
Figure 6: AFD80-3 Mounting Bracket hole locations 3.3 Maximum Carriage Load Calculations The Linear Rail bearings that support the AFD82 Carriage have been selected to provide optimal performance with respect to capacity, size, and low friction. To ensure continued optimal performance it is very important not to overload these bearings. The following diagrams and associated equations are provided to check your application for excessive loading. - Page 12 AFD82 Manual ORP, Copyright PushCorp, Inc. 2001. All rights reserved...

Page 13: Pneumatic Connection
The pneumatic supply system should be configured as shown in the Figure 7. Figure 7: Pneumatic configuration To apply force in the positive + direction, on an AFD81 or AFD82, a Supply Line must be connected to the + Supply Air Port. To apply force in the negative - direction, on an AFD82, a Supply Line must be connected to the - Supply Air Port. -

AFD remains clear of foreign matter. A Purge Port on the AFD82 (See Figure 8.) provides a pneumatic connection to supply this air flow. The port accepts a metric R 1/8 tapered pneumatic fitting. PushCorp can provide fittings for english or metric tubing. -
Page 15: Adjusting Carriage Preload
ORP, 4.0 Adjusting Carriage Preload The required preload on the AFD82 Linear Rails has been set at the factory for optimal performance and, in general, should not require field adjustment. However, there are situations that could arise that cause the Linear Rails to need adjustment. Often a loose, or tight, Carriage on a new AFD is indicative of an improperly designed process equipment bracket. - Page 16 5. After verifying that the Carriage no longer moves laterally, tighten the (2) two Movable Linear Rail M8x1.25 Socket Head Cap Screws on the Moveable Rail side to the torque specified in Section 6.0..

Page 19: Achieving Desired Force
D.C. offset errors. 6.0 Achieving Desired Force The AFD82 is a passive force device that requires the user to provide pressure to the pneumatic actuators. Pressure in the actuators results in an output force at the Carriage. - Page 20 ) so, for every 1.0 psi (0.07 bar) of supply pressure the AFD applies 1.4 lbs (89 N/Bar) of force. This makes the AFD82 very easy to setup. To apply a 20 lbs. (89 N) force just set the supply pressure to 14.3 psi (1 Bar). This, however, does require the user to supply one (the AFD82 requires two) precision pressure regulator to accurately adjust the applied force.
