2 1.0 WIRE PREPARATION Prior to crimping contacts, strip inch (4.83 mm 0.64 mm) of insulation from wire. Correctly stripped wire has neither insulation tearing nor stretching, nor strand damage. 2.0 CONTACT LOADING Circled numbers refer to location on DCT schematic (Section 7.0). Press shutheight should be set at inches ( mm). WARNING: Applicator die DCT is used in many types of presses (manual and auto-matic), therefore guarding is not provided. It is the PURCHASER S RESPONSIBILITY to GUARD all pinch points and moving parts. Before attempting any adjustments or repairs, ALWAYS DISCONNECT THE ELECTRICAL POWER. In order to properly install the contact: 1) Turn brake clockwise to release position (as shown on schematic). 2) Feed contacts into applicator die from left side. Ensure that insulation crimp ears enter the insulation crimp ear alignment groove. 3) Push contacts past feed finger. Continue pushing contacts until first contact is centered with cutter (ref 5.2). 4) Apply tension toward left and turn brake 180 counterclockwise to set position. 5) Slowly cycle press to ensure correct contact installation, alignment and feed (If the press will not cycle, crimp heights may be set too low; ref 3.0) 3.0 CRIMP SET-UP Crimp dial settings ( & ) are for reference only. Only crimps that meet the height and width specifications on TE print can be relied upon to perform correctly. Tensile strength alone is not an appropriate indication of crimp quality. Crimp height and width should be checked on a regular basis to ensure consistent quality. Adjustment of mechanical press may be required in addition to applicator die adjustment to achieve proper crimp heights. 3.1 CONDUCTOR CRIMP HEIGHT/WIDTH ADJUSTMENT Conductor crimp height and width must be as specified in TE drawing Change conductor crimp height by adjusting the lettered dial on top of the applicator die. Revision Letter: C1 Engineering Order Number: Page 2 of 6

3 Ascending dial settings give minimum crimp heights. Descending dial settings give maximum crimp heights. Dial steps are.005 inch (0.127 mm) each. Correct conductor crimps will capture all wire strands within the contact ears. Material extrusion (burrs) under the conductor crimp are normal but should not exceed.010 inch (0.25 mm). Note: Adjusting conductor crimp height will also affect insulation crimp height. 3.2 INSULATION CRIMP ADJUSTMENT Insulation crimp diameter should be the insulation diameter or less. Crimp shall neither hinder removal tool nor damage connector grommet. Reference TE drawing Change insulation crimp height by rotating dial counter-clockwise for maximum height and clockwise for minimum height. Dial steps are.010 inch (0.25 mm) each. Note: Adjusting insulation crimp height will affect conductor crimp height inversely (decreasing insulation crimp height will slightly increase conductor crimp height). 4.0 CONTACT REMOVAL To remove contacts from applicator die: 1) Turn brake clockwise to release position. 2) Lift feed finger while pulling contact strip from die. 5.0 TROUBLESHOOTING 5.1 WIRE STOP ADJUSTMENT Wire Stop is factory set and should only be adjusted if needed to meet this visual inspection: If crimped contacts do not pass this visual inspection, adjust wire stop as follows: 1) Disconnect electrical power to press. 2) Hand cycle press to move ram to the down position. 3) Loosen lockscrew on wire stop. 4) Slide wire stop to required position. 5) Tighten lockscrew. 6) Hand cycle applicator die to assure correct clearance operation. WARNING: 5.2 CONTACT FEED ADJUSTMENT Wire Stop should only be adjusted with ram cycled in the down position in order to avoid potential punch damage. Wire Stop must not touch any moving tooling.

4 Contact feed is set at the factory and should not require adjustment. To adjust contact feed to advance ( right) or to retard ( left): 1) Disconnect electrical power to press. 2) Remove cutter holder and cutter to view alignment with anvils. 3) Single-cycle press to locate contact above anvils (with brake tension applied). 4) Loosen feed adjustment lockscrew. 5) Turn feed finger adjustment counter-clockwise to advance feed (right ). 6) Turn feed finger adjustment clockwise to retard feed (left ). Brake must be released by turning clockwise while lightly pulling contact strip left. Reset brake by turning counter-clockwise after retarding contact feed. 7) Re-tighten lockscrew. 8) Replace cutter and cutter holder. 6.0 MAINTENANCE To ensure correct functioning and maximum service life of the applicator die, maintenance must be performed on a regular basis. This maintenance may include but is not limited to: 1) Lubrication of moving parts. 2) Removal of swarf (cut off material) from applicator, especially in areas including or near feed mechanisms, anvils, punches, etc. 3) Replacement of worn parts. 4) Visual inspection for loose hardware, broken or missing parts. 5) Proper operation of press safety equipment. WARNING: Before attempting any adjustments or repairs, ALWAYS DISCONNECT THE ELECTRICAL POWER. After performing maintenance, ALWAYS REPLACE any SAFETY GUARDS which may have been removed.
