The laser trigger / RPM sensor (in short: sensor) is used as
trigger for vibration measurements and for RPM measure-
ments using a PRUFTECHNIK measurement data collector.
SAFETY INFORMATION
•
Read these instructions carefully prior to use.
•
Use original accessories only.
•
Do not use defective sensors.
•
Do not open the housing.
•
Prior to the installation of measuring components,
switch off the machine and secure it against restarting
according to the applicable regulations.
•
Comply with the applicable safety regulations when per-
forming measurements on machines.
•
Check that the measuring setup can move freely prior to
restarting the machine. Avoid contact of the measuring
setup with rotating machine parts. Risk of injury and
property damage!
•
For storage and transportation, short-circuit the magnet-
ic pole at the stand using the washer supplied. This is to
minimize the magnetic field strength. Observe the safe-
ty data sheet (MSDS) for the magnet holder VIB 3.420
(www.pruftechnik.com).
•
The sensor is in compliance with the relevant European
Directives. The complete Declaration of Conformity is
available at www.pruftechnik.com/certificates.
INSTALLATION
•
Switch the machine off and secure it against uninten-
tional restarting.
Mount sensor to stand:
•
Guide the sensor mount through
the clamping device, until the
knurled nut is centered above the
mount.
•
Hand-tighten the knurled nut.
Mount stand to machine:
•
Select a suitable position on the machine according to
the following criteria: Cleanliness, magnetic properties,
permissible measuring distances, minimum diameter for
curved surface: 40 mm.
•
Carefully place the magnetic base with one edge first to
avoid high impact loads.
•
Attach the measuring mark to the machine shaft.
•
Using the cable, connect the sensor to the measuring
device.

ADJUSTMENT
•
Align the sensor with the laser to the measuring mark.
•
Switch on the laser as follows for adjustment purposes:
-
In "Balancing" operating mode, switch on the laser via
the dialog menu on the measuring screen.
-
In "Multimode" operating mode, start a RPM measure-
ment, or activate the "Coast-down Analysis" measuring
task. The laser switches on automatically.
Do not look into the laser beam! Risk of eye injury!
•
Unlock the ball joint at the stand.
•
Rotate and tilt the fixture, until the
C
laser beam hits the measuring mark. To
achieve stable signals, align the sensor
