TARGET VALUES
INTRODUCTION
Most machines develop a certain amount of
heat while running. In the best case both the
driving and the driven machine are affected
equally requiring no input of compensation
values. But in some applications the driven
machine is either hotter, i.e. a pump for hot
liquid, or cooler than the driving machine.
Machine manufacturers define the thermal
expansion of machines differently, but in most
cases, you will find it as a factor of deliberate
misalignment expressed in parallel offset and
angular error.
In the EVO system, you can pre-set target
values before starting your alignment work.
Accepted values are feet values and angle
and offset values.
The entered values are target values. Target
values mean that these are the values at
which the machine should be positioned when
not running (cold condition) in order to obtain
correct alignment while the machine is
running (hot condition).
