1.0 GENERAL
1.1 LASER SAFETY PRECAUTIONS
The KOHTECT AVV-711 alignment system is the class II laser device at typical wavelength of 670nm,
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 laser the beam at any time!
Do not direct laser beam on to the people’s eyes!
ATTENTION!
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.
Warning!
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.
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 AVV-711 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.
2.0 TECHNICAL DESCRIPTION
2.1. DESIGNATION
AVV-711 alignment system (further as System) is designed for:
checking of shaft alignment of mechanisms;
The checking of shaft alignment means adjustment of the relative position of two coupled machines (e.g.
motor and pump) so that the centre line of the axis will be concentric when the machines are running
during normal working conditions.

2.6 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.
Parallel misalignment of axes – Offset (displacement)
Angular misalignment of axes – Gap
Parallel and angular misalignment of axes – (Offset + Gap)
