GENERAL
SAFETY PRECAUTIONS
Be sure the machines to be measured, cannot be started unintentionally as this can cause
injuries. For this purpose, before the mounting of equipment, either block the power switch
in the “Off” position or remove the safety fuses. These precautionary rules must be
followed until the measuring system is dismantled from the measured machine.
LASER SAFETY PRECAUTIONS
The KOHTECT qb701 alignment system is the class II laser device at typical wavelength of
650nm, delivered output power of less than 1 mW and maximum radiant energy per pulse
of 0.1 mJ. The Class II laser comply with requirement outlined by USA’s FDA as well as
international ANSI, BS 4803 and IEC 825 standard. Be sure to follow the following safety
precautions to avoid personal injuries and damage to the system
Do not look directly into the laser beam at any time!
Do not direct laser beam on to the people’s eyes!
ATTENTION!
Do not expose qb701 parts to heavy impacts, high humidity and extreme temperature.
Do not try open / dismantle measuring units and the display unit –this can damage the
system, and your after-sales service warranty will come void.
INJURY RESPONSIBILITY DISCLAIMER
Neither the NPP KOHTECT enterprise nor our authorized dealers are liable for the damages
caused to machinery or equipment by use of the qb701 system. We carefully check text of
this manual to eliminate errors, nonetheless there may be mistakes or inaccuracy involved.
We will be grateful for your reporting to us about any error, and we will be able to correct
them in the subsequent editions of the manual.

TECHNICAL DESCRIPTION
DESIGNATION
qb701 alignment system (further as System) is designed for measurement of shaft axis
misalignment of coupled machines, and calculation of movable machine adjustment
required to eliminate misalignment that exceeds permissible tolerances;
The machine alignment means adjustment of the relative position of two coupled machines
(e.g. motor and pump) so that the center line of the axis will be concentric when the
machines are running under normal working conditions.

MISALIGNMENT PARAMETERS
Misalignment of any rotating machine is expressed in parallel (Offset) and angular (Gap) of
the shafts. Most frequently in practice, both of them are present simultaneously. Different
kinds of misalignment of axes are shown in Fig. 2.
The parallel (Offset) and angular (Gap) misalignment of axes is determined in two
mutually perpendicular planes. For the purpose of elimination of the parallel and angular
misalignment of axes, in each of the planes a correction of position of the movable
machine (M) will be done.
For the horizontal mounted machine –the movable machine (M) position is adjusted in the
horizontal and vertical planes.
For the vertical mounted machine, operator determines arrangement of the correction
planes, basing on considerations of the convenience and technological effectiveness of
moving of the movable (M) machine.
Stationary machine (S) - in the process of eliminating of the axes misalignment the
position of this machine stay static, i.e. it does not move.
Movable machine (M) –the machine, which position is adjusted for eliminating of the
parallel and angular misalignment of axes.
The measurement system calculates the values of the angular and parallel misalignment of
axes in the plane of the coupling (in two mutually perpendicular planes), and the
adjustment values for the machine feet on the movable (M) machine, that is necessary for
elimination of this misalignment of axes. Fig. 3 shows misalignment of axes and the values
for its correction just for vertical plane.

Angular misalignment of axes –Gap

MOUNTING TRANSDUCERS
•Firmly tighten rods 1 into the shaft brackets 2.
•Put thumb nut 3 into the bracket 2, then hook the chain 5 on the stud 4.
•Firmly tighten the thumb nut 3. Shaft brackets with rods must be mounted at the
same angular position.
•Mount transducers on the rods. Always try to mount transducers at minimal
possible radial height. Make sure that transducers are not touching brackets or
machine parts.
