e) Set the SW702 (LTACH) and SW703 (RTACH) switches to accommodate the voltages measured in

step c) above.  Both switches are set in exactly the same way.  Use the chart below.  If the machine
was run at half speed, multiply the voltages by 2 and use those values for the switch-setting chart
below.

Note

:  Remember to use the computed, not the measured, voltage for RTACH.  Multiply the

computed voltage by 2 if the machine was run at half speed.

f) Set the LTACH span pot.  Run the machine at maximum speed.  Measure the LTACH output

voltage at test points TP701 (+) and TP703. Adjust the LTACH Span pot. (RT701) for 10.0 volts.

g) Set the RTACH span pot.  With the machine still running at maximum speed, measure the RTACH

ouput voltage at test points TP702 (+) and TP703.  Adjust the RTACH Span pot. (RT702) for 10.0
volts AT THE CORE DIAMETER.  As an alternate method, measure the roll diameter and adjust
the RTACH Span pot. to a voltage equal to:

10 x (core diameter)/(roll diameter).

h)

Note

:  If you ran the machine at half speed, set the output voltages at 5.0 volts in steps f) and g)

above.

6.4 DIGITAL METER (See Page 6 for description)

Before using the Digital Meter, it must be adjusted to accommodate the expected maximum tension. 
THIS HAS BEEN DONE AT THE FACTORY.  NO CHANGES SHOULD BE NEEDED!

The calibration procedure is the same as for the analog meter.  Refer to Section 4, page 18.

CAUTION:

  When setting the ZERO pot. pay attention to the under-range indicator.  The correct

setting is where the light just goes out as the ZERO pot. is turned clockwise.

*****  

OPTIONAL PROCEDURE

  *****

The range of the Digital Meter is set at the factory, and is based on the maximum tension desired by
the user.  Use the following procedure to reset the range if you need to read higher tension than the
meter was originally set to read.   

NOTE

:  There has been a change of terminology on the circuit board from the original design. The

older terminology is in parentheses in the following procedures.
