Multiplier
 - Configures the tool to in clude gearing added to the base model. 
Units: Gear Ratio * 100. 
a.  Example: Adding a multiplier with a gear ratio of 5:1, Multiplier setting = 5. 
 
 
Obstruction Torque  - In 1st 90° degrees of rotation in  the tightening direction cycle will be 
aborted if this torque is exc eeded. If the tool rotates 90° degrees and stops without any 
obstruction, the value is too low. 
 
Open Loop  - After reaching the open position, this  open loop torque prevents the...

Buttons and LED’s 
 
Calibrate Buttons - After a tool has been  worked on, it is possible the relationship between 
hall sensors and magnet have c hanged.  Using the Tool Button Calibration screen calibrates 
the field between the two.  Test Trigger, Ccw,  Center and Cw positions and send the values 
to the Tool. 
  
LED States  - Turns the tool lights on, off, or fl ashes.  Used for testing of the Tool

Service and Calibration Log 
 
The  Service  Parameters  are  stored  in  the  memory  of  the  Tool  and  they  can  be  viewed  in 
this  screen.  The  Next  Service  cycl
e  or  Next  Service  date  in  this  screen  will  turn  red  if  they 
exceed the value the service is due.

2.8 Rundowns 
Data for rundowns in all or selected Parameter Sets can be displayed in a tabular format. 
This information can then be saved as a “Ms.csv” File. 
 
  You can print the rundown results by  using File ->Print in the menu. 
 
  Rundowns must be saved to a file before the statistics function can be used to 
evaluate the data. 
 
  Controller memory can be cleared by cl icking the “Clear  iEC Rundown Memory” 
button

2.8.2  Select Parameter Set 
 
  To view results of all saved rundow ns, regardless of Parameter Set, select 
zero (0) 
   To view results of rundowns for a specific Parameter Set, select the 
appropriate Parameter Set number 
   To select the colums you  want to see, select custom and choose the columns 
from the selection menu 
   You can restrict th e number of rundowns you want to see by selecting the 
Max. Rows (0 means all)  
   The Rundowns are ordered by latest first. So the Re cent...

Log info describes the usage of the Controller and the tools that have been used with 
that controller.  
 
POR Counts
 - Number of times the controller power has been cycled. 
 
Controller Cycles  - Number of rundown the controller has completed. 
 
Tool Log  - Displays history of tools that  have been previously connected to the 
controller. 
 
Monthly Usage  - Displays history of the number  of rundowns the controller has 
preformed divided in to...

2.10  Statistics 
The statistics page takes a collection of final torque samples from a rundown file then 
calculates and displays statisti
cal information about the collecti on. In addition, a histogram is 
plotted, and the final torque for each rundown is displayed graphically. The maximum 
number of rundowns that can be  evaluated is 2048. If more data is stored in the file, then 
data for only first 2048 rundowns are used.  Tor que values are...

PSet Selection (Parameter Set):  
a.  Only rundowns with the PSet selected  are used in the collection. In addition, 
Only Rundowns with settings for  Torque High Limit, Torque Low Limit, and 
Target that match the first rundown are used in the collection. 
b.  If 0 is selected for the PSet, all rundow ns in the file will be used in the 
collection.

Stats: 

  POP:  Population; The total number of observations used to calculate the statistical data. 
   Mean:  (Sum of All Readings)  / (Number of Readings) 
    CP: Overall capability, which is the ratio of  6 sigma to the tolerance.  The equation for 
CP is:      (Torque High Limi t – Torque Low Limit) / 6 Sigma 
   CPK:  Process capability, which takes both sigma and mean into account.  The equation 
for CPK is the smaller of:  (Torque High Limit – Mean) / 3 Sigma    or   (Mean – Torque 
Low...
