KOHTECT qb701 LASER SHAFT ALIGNMENT SYSTEM USER’S MANUAL

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...

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. S transducer installed on the shaft of Stationary machine M transducer installed on the shaft of...

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...

SYSTEM PACKAGE The System includes (Fig. 1): 1- AVV-711 display unit 2- two measuring transducer units – S, M 3 3- universal chain brackets for mounting of measuring units S, M 4- measuring tape 5- 120…240 Volts AC charger 6- USB PC communication cable 7- Operating instructions manual and ConSpect freeware on the internal drive of display unit 8- Carrying case with form-inserted 8 SYSTEM OVERVIEW Power button Detector window Laser aperture Locking thumb nut Mini USB charger connector

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. S, M transducers to be installed at the same height with labels faced up S transducer installed on the stationary machine Datum lines for measuring of dimension input M transducer...

LASER BEAM ADJUSTMENT • Loosen thumb nut and horizontally adjust transducer so the middle of the laser line is at the transducer’s window. Slightly tighten thumb nut then vertically adjust laser line to the center of the transducer’s window. Firmly tighten the thumb nut. Adjust second transducer in the same way. Use an angular adjustment only. Do not change transducers installation height!

GETTING STARTED COMMON CONTROL KEYS CONSIDERATION To turn ON/OFF display unit and transducers – press and hold the power button ~2 sec. In case the system hangs and device did not respond to any keys - press and hold the power button for ~10 sec, the system will be reset. To close any currently active window, without saving, except main menu of the device, press button (it serves as escape key). button in most cases causes applying (saving) changes (invoke selection) and exit (from edit box; or from current window, except such windows as collect data, aligning, soft foot and so on where it...

qb701 User’s Manual SETUP MENU ITEMS – to setup date and time – to set device auto off delay in seconds. When set to 0 – auto off is disabled. – to install license file which enables measurement functions. Press 9, browse to the license file, press Enter to open and install licenses. + Function enabled, valid until 01.01.2099 Serial number – to switch between wireless/cable transducers connection. For wireless connection – press 1 or 2 to enter number of transducers to be connected

qb701 User’s Manual – to choose user interface language keys to choose language, then press – to switch qb701 into USB mass storage device mode. By default device can be connected to the PC via Microsoft Windows Mobile Device Center. USB mass storage device mode can be used as alternative. – to adjust the display backlight brightness to choose default alignment biaxial mode. In biaxial mode both horizontal and vertical machine aligning with live data update could be made at a static transducers position (e.g. 3 h). For QB-TSM transducers the only available mode is 1-D
