Aimco Brakes Monitor UEC4800TP Instruction Manual

  
Input and Output check (wiring diagnosis of the terminals and the tool)

By monitoring the input condition to the terminal block and making the compulsory signal output to 
either the terminal block or the tool, UEC checks the incoming wirings of the terminals of UEC, the tool 
and the sensor cable connected.   
 
If you enter the IN-OUT CHECK screen, UEC starts from the check of the input terminals.   









Input terminals now been switched on are colored in blue.       ...

   
Zero point adjustment
UEC displays the values of the torque sensor’s zero point and the cal number confirmed by the zero 
check and cal check.     
Displayed values are of the absolute values.   










[ZERO] shows the zero point value, and [PROOFREADING VALUE] shows the calculated value of 
CAL x Proofreading Ratio x Tool Ratio.   
If the zero point deviates around [0], touch 
 to have UEC correct the zero point deviation.    A 
message      ZERO POINT ADJUSTING…      appears in...

  
WORK No. change

UEC makes the work number change by short-circuiting the input signal terminals and the common 
terminal.    In accordance to the setting value of WORK SIG. SEL. of the MODE SETTING screen, the 
input signals to the terminals become different.

%Torque polarity change

Unless torque polarity of UEC is changed over, UEC is unable to either measure the torque of the left-
hand threaded fasteners or control the geared transducerized tools because the torque signal from the 
tool is input in the minus direction.    You need to change over the UEC’s torque polarity for left-hand 
threaded fasteners.    Change over is made by DIP switch in the board inside of UEC.

Basic setting 
The BASIC SETTING screen consists of two pages.         
First screen (1/2) 
 










 
TORQUE LOW    (Torque low limit value)  
Default:  80.0 [Nm] 
Setting range:  0.0 –999.7 
Setting condition:    Torque low limit value < Torque CUT value 
]Function^ 
Value for the measured torque low limit judgment 
 
TORQUE HIGH (Torque high limit value) 
Default:  60.0 [Nm] 
Setting range:  0.4 –999.9 
Setting condition:    Torque CUT value < Torque high limit value...

  
TORQUE SENSOR 1 (Torque sensor resistance value []) 
Default:  700 
]Function^ 
Resistance value consisting of torque sensor circuit 
Choose from 480, 700 or 350, which agrees to the specifications of torque sensor connected.     
Set [700] for EC wrenches     
Do not enter any value for MC wrenches.    Setting value is not displayed on the screen if the sensor 
select switch is set to MS.     
 
TORQUE SENSOR 2 (Torque sensor rated strain value)  
Default:  750 
Setting range:    100 - 4400...

PROOFREADING RATIO 
Default:  1.00 
Setting range:  0.01 _ 9.99   
]Function^ 
This is the proofreading ratio which makes the break-away torque agree to the UEC displayed 
torque.   
 
 
TOOL RATIO 
Default:  1.00 
Setting range:  0.01 – 9.99 
]Function^  
This is the reduction ratio of the geared pulse tool.     
 
 
PROOFREADING VALUE  
Default:  1000 
Setting range:  0.01 – 9.99 
]Function^  
Proofreading ratio x Tool ratio x CAL value...

   
MODE Setting 
MODE SETTING screen consists of four pages.       
First screen  (1/4)











INITIAL ERROR (Initial error detection)      (former name: MODE 1) 
Default:  0 
Setting 0:    Not detect the initial error 
Setting 1:    Detect the initial error 
]Function^ 
Use to detect the double-fitting or cross thread.   
UEC detects the initial error if the consumed time from start torque level to torque cut value is less 
than time of the initial error detection timer....

FASTENING ERROR   
(After of post error detections LO.E/CYL.E/F.E)      (Former name: MODE 3) 
Default : 1 
Setting  :  0  UEC gets non-operative status unless 
 is touched or reset terminal is switched 
on.  Valve remains switched on.   
Setting  : 1  Next operation performs start-reset without touching 
 or switching on reset 
terminal, and UEC gets operative status.   
If 0 is set to EXTERNAL START, the torque input (greater than start torque value) of 
next operation performs start-reset and...
