Page 5: Verify Your Soft Touch Sensor Board Is Correct
VERIFY YOUR SOFT TOUCH SENSOR BOARD IS CORRECT The SOFT TOUCH sensor board can be configured in several ways. Before turning power on, check to be sure that the three switches are in the MFDC (up) position. MFDC POSITION SOFT TOUCH FOR PNEUMATIC RIVETERS |... -
Page 6: How System Operates
SOFT TOUCH PINCH-POINT SAFETY SYSTEM FOR INSTALLATION ON PNEUMATIC RIVETING MACHINES HOW THE SYSTEM OPERATES: When the voltage from the foot switch goes HIGH, this voltage goes to the 9280-TS7 SOFT TOUCH detection board, terminal #9. The output terminal #11 (SVL) goes HIGH to turn on solenoid valve SVL. This closes the riveting mandrel under low force using low air pressure on the forward port of the riveter air cylinder. -
Page 7: Hose Connections
HOSE CONNECTIONS Note: If the riveting machine has an existing solenoid valve or pneumatic foot switch, this system REPLACES these components. Connect to air cylinder port that opens the riveting mandrel. If cylinder Connect to point between air filter/ is spring return, install a 1/2” plug water trap and input to existing into this bulkhead. -
Page 8: Preparing Riveter
PREPARING RIVETER Tool Bar Type Mounting The tooling bar must be electronically isolated from the riveter frame. Counterbore the two screw pockets in the tooling bar so that they will clear the new phenolic tubing, phenolic washers, and steel washers. Drill and tap a hole in the tooling bar for connection to one of the blue wires from the SOFT TOUCH system. - Page 9 PREPARING RIVETER Direct Tool Mounting Type The lower tooling must be electronically isolated from the riveter frame. Bore out hole in bottom of riveter and install phenolic or nylon sleeve and washers. Drill and tap a hole in the frame and install a crimp terminal with one wire as shown. Install a copper or brass terminal pad as shown and connect the other blue wire.

Page 12: Depth Switch Option, Rst-403, Rst-404
OPTIONAL DEPTH SWITCH RST-403, RST-404 This option allows use of either CONTINUITY DETECTION or closure of a DEPTH SWITCH to turn on the full rivet pressure. It is useful when parts being riveted have a non- conductive coating. INSTALLATION: RST-403: Mount the PNP proximity switch that is supplied with this option on the body of the rivet machine using the mounting bar. - Page 13 OPTIONAL DEPTH SWITCH RST-403, RST-404 CONTINUED Wire the switch to match the appropriate hookup below. USE IN PRODUCTION: Turn the key counter-clockwise to the CONTINUITY position. The yellow panel indicator will glow. In this position, high riveting pressure will only be applied when electrical continuity is detected between the upper and lower riveting mandrels.

Page 14: Adjusting Soft Touch Valves
ADJUSTING THE SOFT TOUCH VALVE SYSTEM Set the CLOSE pressure regulator inside the enclosure so that the CLOSE PRESSURE gauge on the door is at approximately 3psi. Set the OPEN pressure regulator inside the enclosure so that the OPEN PRESSURE gauge on the door is at approximately 12 psi. -
Page 15: Setting Maximum Detect Time Switches, Blank Time
SETTING SOFT TOUCH BOARD MAXIMUM DETECT TIME SWITCHES Locate the four-section ADD FOR DETECT TIME DIPswitch on the left side of each SOFT TOUCH board. This switch is marked: 1, .75, .5, and .25 seconds. Set the switches to a value that is about 2 times how long it will take for the riveting mandrel to close. The on-board computer adds the value of these switches. -
Page 16: Startup Procedure
START-UP PROCEDURE Turn on power to the SOFT TOUCH control. The SOFT TOUCH annunciator panel should go through a test procedure and then the READY LED should turn on solidly. If the READY LED does flashes slowly or quickly see the trouble shooting section in this direction book. -
Page 17: Testing Riveting Mandrel Closing Force
TESTING MANDREL CLOSING FORCE Adjust the pneumatic system to produce safe closing mandrel closing force using the directions on page 9. Use the TEST switch to close the riveting mandrel each time you make a change in the pressure regulator settings. A successful pneumatic setting will provide a force under 25 pounds between the mandrel and lower tool. -
