EC Declaration of Conformity
The qb701 complies with EMC Directive 2004/108/EC and other relevant European safety and performance standards.
Technical Description
The system measures shaft misalignment in parallel (offset) and angular (gap) values, calculating necessary adjustments for correction.
Specifications and Features
  • Measurement accuracy: 1%+0.01
  • Laser type: Visible red 635-670 nm, <1 mW
  • Operating temperature: -10 to +55°C
  • Power supply: Rechargeable Li-Ion battery
  • Features: Horizontal and vertical alignment, editable tolerances, shimming simulator.
System Package
Includes a display unit, two transducer units, mounting brackets, charger, USB cable, and carrying case.
Mounting and Adjustment
Transducers should be mounted at the same angular position on shafts, with laser beams aligned to transducer windows.
Getting Started
Instructions for powering, resetting, and navigating the menu are provided, with auto-save functionality.
Device Setup
Configure settings such as date/time, auto-off delay, connection type, interface language, and display brightness.
Horizontal Machine Alignment
Mount transducers, run the alignment program, enter dimensions, and set parameters for accurate alignment.
Measurement Mode – Clock Type
Measure misalignment by turning shafts to 9, 12, and 3 o’clock positions, taking readings at each to calculate corrections.
Transducer’s Positions Conventions
Adhere to angular positions: 6 o’clock - 0°, 9 o’clock - 90°, 12 o’clock - 180°, 3 o’clock - 270°.
Parameters
Run the Horizontal program, choose New Task, edit dimensions, and toggle settings like Spacer shaft and data input type.
Tolerance Setup
Use predefined RPM/tolerance tables or enter user-defined values, saving changes as needed.
Taking Measurements
Clock Mode: Take readings at 9, 12, and 3 o’clock positions. Multipoint Mode: Collect readings at any position from 3 to 36. Auto Shooting Mode: Automatically record data at stable positions.
Readings Quality Assessment
Data quality is assessed by standard deviation, indicated by color-coded dots: Blue (impossible), Green (good), Yellow (acceptable), Red (poor).
Result Screen
Displays misalignment and required corrections with directions for adjustments shown by blue arrows.
Movable Machine Adjustment
For vertical adjustments, use 6 or 12 o’clock positions; for horizontal, use 9 or 3 o’clock positions.
Machines with Spacer Shaft
Activate the Spacer Shaft option and follow the Horizontal program procedure.
Lock Feet Pair
Swap movable machine if needed, enter missed dimensions, and lock feet pair as required.
Report File Saving
Save report files at any alignment stage to an internal SD card or USB drive.
Soft Foot
Run the Soft Foot program to eliminate conditions before alignment by loosening and tightening bolts.
Vertical Machine Alignment
Mount transducers, run the Vertical program, mark positions, enter dimensions, and set parameters for alignment.
Machine Correction @45
Place transducers at 45° positions to avoid turning shafts when switching correction planes.
Charging Batteries
Charge using a USB type AC charger or PC/laptop USB port, with automatic termination upon completion.
Firmware Upgrade
Ensure full battery charge and follow steps to upgrade firmware using a USB thumb drive or Windows Mobile Device Center.
Firmware Upgrade Procedure
1. Initiate upgrade by pressing the designated key.
2. Confirm start of upgrade.
3. Replace existing files by pressing specified key and confirming.
4. Choose 'NO' when prompted, then proceed.
5. Complete upgrade and turn off device.
Standard Tolerances of Shaft Misalignment
Outlines alignment tolerance standards for machinery with flexible coupling, categorized by speed (rpm) with offset and angular measurements.
Delivery Set
Includes control display unit, measuring transducer units, brackets, chains, supporting rods, AC charger, tape measure, carrying case, operating instructions, ConSpect Software, and USB cable.

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...

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