6.1.3.1 - Maintenance info screen
● MAINT OFF: maintenance is not reached yet.
● MAINT ON (time): Maintenance is reached according
to the selected date.
● MAINT ON (count): Maintenance is reached
according to the tool counter.
6.1.4 - CALIBRAtION menu
The calibration procedure is recommended to
compensate for any possible drift of the tool torque or
after each change of tool element.
6.1.4.1 - spINDLe MANu menu
This menu is used to calculate and to apply a torque
correction coefficient to the torque value of the selected
cycle.
The torque transducer inserted in line with the tool can
be connected to any measuring unit in the Desoutter
range.
Run a tightening cycle 5 times and manually enter the
values read on the standard instrument.
● The Reset value key resets the readings.
● The Reset coeff. key displays coefficient 1 by default.
Depending on the option selected (K Torque/spindle or K
Torque/cycle) in the "STATION menu", page 30, the Torque
correction coefficient is saved:
● Either in the tool memory.
● Or in the controller.
the torque and angle reports Must be
correct to allow the procedure to be
processed in normal conditions.
6.1.4.2 - spINDLe AutO menu
Specific to EC tools only !
The target of this operation is to recalibrate completely
the tool, for example after a motor change or a tool
electronic change. This needs skilled operators.
the tool will be tuned over its entire
operating torque range.
Equipment required:
● A torque measuring unit DELTA connected to the
CVIR II controller via a serial cable.
● The tool to be calibrated with a transducer and its
cable.
Program the measuring unit by pressing
/
to
display [standard] in the summary line, then
to
display [Calib CVIR].
Select the type of transducer to be used by pressing
then
/
.
If the measuring unit is not correctly connected or
programmed, an error message [Wait. for conn] is
displayed on the screen.
Follow the instructions displayed on the CVIR II screen.
10 tests can be run and they are performed at various
increasing speeds.
Run one test after another.
the tightening is performed up to the MAX
torque.
