Chapter 3: Operating Instructions

Operating Manual

6

6.

Turn the CSP dial counterclockwise somewhere below the reading where the Safetimeter began

to count.

7.

Slowly turn the CSP dial clockwise and stop when the Safetimeter begins to count. The

number displayed in the CSP dial is the distance between the base of the P/V transducer and

the ram.

8.

Subtract 1/2 of the press stroke from the number displayed in the CSP dial to calculate the

Control Start Point.

Example: If the number displayed in the CSP dial is 240 (24.0”) and the press stroke is 6”, subtract 3”
(1/2 stroke) from 24.0” equals 21.0”. This is the mid-stroke position. While it may not represent the
exact 90 degree point of the crankshaft, it is close. This electronically measured point in the stroke will
start the Safetimeter, and fi res the Auto-Hand.

9.

Set the CSP dial to the result of Step 8. From the example, the CSP dial would be set to 210

(21.0”)

B. Setting the CSP dial when the press stroke is not known.

1.

Find the open height of the press by performing steps 1-7 in subsection (A). Record the

distance determined in step 7.

2.

Lower the press ram to the bottom of the stroke. Find the closed height of the press by

performing steps 2-7 in subsection (A). Record the distance determined in step 7.

3.

Using the two distances determined from steps 1 and 2, calculate the mid-stroke position using

the following method: Add the two measurements together and divide by two (2).

Example: Midstroke = (Open Height + Closed Height) ÷ 2

4.

Set the CSP dial to the above result.

C. Setting the CSP dial at the 90 degree crankshaft position.

To test at the 90 degree crankshaft position, or when the P/V Transducer cable is angled, the CSP will
act as a reference setting.

1.

Inch the press to 90 degrees by observing the crankshaft or stroke indicator.

2.

Perform steps 2-7 in subsection (A).
