3.4: Using Auto-Hand
The Auto-Hand is designed to release or push press controls. It can release a two-
hand control or inch button, or push an E-Stop button. Auto-Hand is not required if
you are using one of the optional Manual Start Switches.
Using Auto-Hand with Two Hand or Inch Control (Release to Stop)
The Auto-Hand releases or pushes buttons with a spring-loaded plunger. When the
plunger is pushed, it will latch into position. The Safetimeter provides a voltage pulse
to energize a solenoid that releases the spring loaded plunger. If the two-hand control
has a ring guard, the Auto-Hand should rest on the guard and the three support
legs are not needed.
1. Connect Auto-Hand to the Safetimeter. Depress the plunger and place the
extended end over one of the two-hand buttons. Rest Auto-Hand on the
button’s ring guard. If no ring guard exists, screw in the three legs to serve as a
rest. Use your other hand to press the other button.
2. Cycle the press. The Auto-Hand will actuate when the desired CSP is reached,
releasing the button and initiate a press stop.
NOTE: The Auto-Hand can only release 10 lbs. of force and may not release if pushed
against the button with excessive force. In this case, use one leg as a spacer,
to prevent applying excessive force. Place over switch and repeat step 2.
NOTE: Be sure the press has stopped before the bottom of the stroke. Readings are
invalid if the press goes through the bottom of the stroke before stopping. If
this happens, increase the CSP setting slightly until the press stops before
the bottom.
3. Remove Auto-Hand and restart the press to return the ram to top stop.
4. Read the Safetimeter display. This value is the Stop Time or Safety Distance,
depending on the display mode selected prior to the test.
Using Auto-Hand with and E-STOP Button (Push to Stop)
1. Screw the plunger extension into the plunger end that retracts when the
plunger is depressed. This end is used to push an E-STOP button. Attach the
three legs to this side, if required.
2. With the Auto-Hand plunger depressed, place the unit over the E-STOP button
to be pushed. Check that the plunger extension is adjusted out far enough to push the
button when the Auto- Hand releases.
