2.8.2 Select Parameter Set 
 
  To view results of all saved rundowns, regardless of Paramete r 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 cus tom and choose the columns 
from the selection menu  
   You can restrict the number of rundowns you want to see by selecting the 
Max. Rows (0 means all)  
   The Rundowns are ordered by latest first. So the Recent...

2.9    Log Info  
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...

2.10    Statistics  
The statistics page takes a collection of final torque samples from a rundown file then 
calculates and displays statistical information about the collection. In addition, a histogram is 
plotted, and the fi nal 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.  Torque...

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 rundowns 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 Limit  – 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...

Histogram of Final Torque Samples 
The histogram shows the frequency count of the number of times that a specified interval, or  
bin, occurs in the collection of final torque samples.  The range of the histogram is equally 
divided in to a specified number bins using the following equations:  
  The width   
  of the frequency bin is   
o   
o  Where:   
   m is the selected Number of Bins . 
   max is the upper ceiling for the torque range to be evaluated ( Range 
Ceiling ) 
   min is the...

Final Torque Sample Graph 
The Final Torque Sample graph shows the final torque of each rundown in the collection.   
For reference, the Parameter Set values for Torque Hi, Torque Low, and Torque Target 
are taken from the first rundown in the collection and plotted as vertical lines.  
 
 
 
2.11    AcraVision   
AcraVision displays the current rundown information in an easy to read screen.  If there is 
a  failure in the tightening the Torque/Angle  is displayed in red.

 Hyper -terminal like screen that can be used to monitor the serial output messages from 
the iEC controller    
 
3.  Addendum 
3.1  Fault codes   
Fault codes are displayed to inform the operator about what is happening in the Controller 
and why something doesn’t behave as expected.

3.2 Trouble Shooting 
Fault Description  
TID Timeout:  No Communication between the tool and controller. This fault condition 
is usually caused by a problem in the tool ID board. Try connecting another tool to the 
controller  
    Tool GND:  The tool ground loop is broken. This fault condition is usually caused by  a 
problem in the controller  or tool . Try the tool and cable on another controller. The fault 
can be intermittent.   
    Power on Throttle:  The System thinks that the throttle is...

 48 
Tool Level: The tool transducer output voltage has exceeded the maximum or 
minimum allowable value. Try the tool on another system.  
 
Locked rotor : The controller has not sensed hall transitions from the motor for a 
period of time. This is possible if the tool is trying to achieve a high torque at a low 
speed. Increase the rundown speeds and make sure the tool is calibrated properly. It 
is also possible that the controller is faulty. If the tool does not run at all try 
connecting it to a...
