sensALIGN5 EX components

sensALIGN 5 EX laser

The semiconductor laser diode emits a ray of red light (wavelength 630 – 680 nm)
which is visible where it strikes a surface. The Class 2 laser beam is emitted with a
diameter of approx. 5 mm (3/16”).

The laser is turned on by pressing its On/Off push button switch. The “beam active”
LED lights red.

WARNING

With the laser on, DONOTstare into the laser beam!

1: Vertical beam position adjustment thumbwheel; 2: “Beam active” indicator LED; 3: Rubber

housing; 4: Horizontal beam position thumbwheel; 5: Laser dust cap in “open position”; 6:
Laser emission aperture; 7: On/Off push button switch; 8: Locking knob

The beam is adjusted during set-up by changing its vertical and horizontal angles using the pos­ition thumbwheels, so that the beam strikes the sensor lens perpendicular to the lens surface.

The laser is water and dust resistant (IP 65). The internal optics and electronics are internally
sealed, preventing possible contamination.

CAUTION

The battery compartment is not watertight. If water enters this compartment, open it
and dry it out. The two AA size batteries should then be replaced.

ROTALIGNtouch EX 19

On-board help

Laser batteries

The laser is powered using two high energy AA size alkali-manganese 1.5 V batteries (use only
Duracell Industrial ID 1500 or Energizer E91). These provide a typical operating duration of
120 hours.

CAUTION

As the battery becomes depleted, the colour of the ‘laser active’ indicator LED changes
from green (full) to yellow (half full) to red (empty). When this occurs, the batteries
should be replaced.
If the laser is not in use for extended periods of time, a month or more, the batteries
should be removed from the unit.

Replacing laser batteries

Batteries must be changed only outside the explosive area! Note that only alkali-man­ganese batteries can be used in explosive atmospheres.

The batteries are replaced by undoing the quarter-turn screw (1) on the battery compartment
cover (2) by rotating it by at least 90° (1/4 turn). With the screw loosened, lift the cover, and
then use the red strap (3) to remove the batteries. Replace both batteries at the same time.

CAUTION

Under no circumstances may the two smaller housing hex head screws be removed, as
that would void all warranty coverage.

Used batteries should be disposed of in an environmentally-sound manner!

20 Version:2.3

On-board help

sensALIGN 5 EX sensor

The sensor contains two position detectors, which measure the exact position of the laser
beam as the shafts are rotated. The sensor also contains an electronic inclinometer for shaft
rotation measurements.
The sensor has two indicator LEDs on its front side, one green and the other red, to indicate
beam adjustment.
The sensor is powered using the intrinsically safe RFmodule via the module cable.

1: Distance marking; 2: Laser beam position LEDs; 3: Rubber housing; 4: Scratch-resistant

lens; 5: Sensor dust cap in “open position”; 6: Cable socket; 7: Locking knob

Opening the sensor/laser aperture

l (1) Lift the dust cap slightly in the direction shown by the bold red arrow.
l (2) Rotate the dust cap in either direction as shown by the bold red arrow.
l (3) Lock the dust cap in its “open position” highlighted in red.

Mounting components

Mounting brackets

Note

The system is delivered with fully assembled brackets, and with the intrinsically safe
sensALIGN 5 laser, sensALIGN 5 sensor and RF module already assembled. In this case,
the bracket holding the laser is mounted on the shaft on the left side of the couplings or
the solid coupling hub on the left side. The bracket assembly holding the sensor con­nected to the RF module is mounted on the shaft on the right side of the couplings or the
solid coupling hub on the right side.

Mount the brackets on either side of the coupling on either the shafts or on the solid coupling
hubs, and both at the same rotational position.

Please note the following in order to obtain the highest possible measurement accuracy and to
avoid damage to equipment:

CAUTION

Ensure that the brackets fit solidly onto their mounting surfaces! Do not use self-con­structed mounting brackets, or modify the original bracket configuration supplied by
PRÜFTECHNIK (for example, do not use support posts longer than those supplied with
the bracket).

Note

If the brackets have not been fully assembled, follow the mounting procedure below.

Bracket mounting procedure

l Choose the shortest support posts which will still allow the laser beam to pass over or

through the coupling. Insert the support posts into the bracket.

l Fasten them in place by tightening the hex screws on the sides of the bracket frame.
l Place the bracket on the shaft or coupling, wrap the chain around the shaft and feed it

through the other side of the bracket: if the shaft is smaller than the width of the bracket

ROTALIGNtouch EX 23

On-board help

frame, insert the chain from the inside of the bracket as shown in the diagram; if the
shaft is larger than the bracket width, insert the chain into the frame from the outside.

l Catch the chain loosely on the anchor peg (A).
l Turn the bracket thumbscrew to tighten the assembly onto the shaft.
l Clip the loose end of the chain back onto itself.

The bracket should now be tight upon the shaft. Do not push or pull on the bracket to check,
since this could loosen its mounting.

To remove the brackets, loosen the thumbscrew, then remove the chain from its anchor peg.

Mount intrinsically safe RF module, sensALIGN5 sensor and laser

l Mount the RF module on the support posts of the bracket fixed on the shaft of the right

machine (usually moveable machine). The module clamps on the support posts. It is
recommended to slide the RF module all the way down onto the bracket frame.

l Mount the intrinsically safe sensALIGN 5 sensor on the same support posts as the RF

module. The yellow locking knobs should be loose enough to allow the sensor slide onto
the support posts. Lower the sensor as close to the RF module as possible.

24 Version:2.3

On-board help

l Clamp the sensor onto the support posts by tightening the yellow knobs.

l Connect the sensor to the RF module using the RF module cable.

The shorter 90-degree connector of the RF module cable is connected to the 8-pin sensor
socket. The keyway orientation should be noted, and the knurled sleeve of the connector
screwed in until it is snug. The longer 90-degree connector of the RF module cable is
inserted into the four-pin socket on the side of the RF module with a groove, matching
the red dot on the plug to the groove on the socket to ensure proper plug orientation.

l Use its power switch (1) to turn the intrinsically safe RF module on.

The intrinsically safe RF module powers the intrinsically safe sensor.

Note

For details on the intrinsically safe RF module please refer to the included RF mod­ule operating handbook DOC 04.202.

l Mount the intrinsically safe sensALIGN 5 laser on the support posts of the bracket fixed

on the shaft of the left machine (usually reference machine) – as viewed from normal
working position. Ensure that the yellow locking knobs are loosened enough to let you
slide the housing onto the support posts.
Switch the laser on by pressing its On/Off push button (1). Ensure that the laser beam
can pass over or through the coupling and is not blocked.

26 Version:2.3

On-board help

Both the sensor (3) and laser (2) should be at the same height, as low as possible, yet high
enough for the beam to clear the coupling flange. They should also visually appear to be rota­tionally aligned to each other.
Make the final adjustments, loosening the brackets slightly if necessary, then rotating them,
and re-tightening.

In some cases, if the coupling is large enough, a coupling bolt can be removed and the laser
beam shot through the bolt hole, in order to avoid protruding radially beyond the coupling's
outer diameter (O.D.).

Both sensor and laser should be at the same height, as low as possible, yet just high enough
for the beam to clear the coupling flange. They should also visually appear to be rotationally
aligned to each other.

and then open the sensor aperture by lifting and rotating its dust cap until it rests on its “open”
position.

Note

It is highly recommended that before mounting the laser on its bracket, both yellow
adjustment thumbwheels be brought to the approximate center of their travel range.
This will ensure that the beam is emitted from the laser as straight as possible and not
at an angle.
Also make sure both brackets are rotationally aligned to each other.

Laser beam adjustment

Laser adjustment wizard

The laser adjustment wizard is the primary laser beam adjustment feature in the touch
device. If the sensor is initialized, and the laser beam is not centered, use the wizard to adjust
the laser beam correctly. The wizard arrows indicate the direction and amount in which move­ment should take place.

l The wizard arrows next to the laser position thumbwheels (1 and 2) indicate the dir-

ection and magnitude in which the thumbwheels are to be moved in order to adjust the
laser beam correctly.

l The wizard arrows away from the thumbwheels (e.g. 3) indicate the direction and mag-

Measurement

The desired measurement mode is selected while in the measurement screen.

Tap the measurement mode header [1] to access the measurement mode carousel.
Swipe the carousel up or down and select desired measurement mode.

In the above example, Multipoint measurement has been selected. The quality of the meas­urement may be displayed either as a measurement standard deviation (SD) or measurement
quality factor.
Standard deviation(SD) is the root mean square deviation (mean of the means) of the
measurement points. It describes how closely a group of data points are clustered around the
average of those data points. It is a measure of the measurement calibre. The smaller the SD,
the better the quality of the data collected.
Measurement quality is a factor defined by the following measurement and environmental
criteria: angular rotation, standard deviation of the measurement ellipse, vibration, rotation
evenness, angular rotation inertia, direction of rotation, speed and filter output. The higher the
factor, the better the quality of measurement.

The desired factor is set by tapping the corresponding item. The averaging is set by tapping
the 'Averaging' button.

Averaging

In certain industrial conditions, it may be necessary to increase the number of measurements
(recorded laser pulses) to be averaged when taking readings to attain the desired accuracy.
Particular cases include environments with increased machinery vibration. An increased aver­aging also improves the accuracy when measuring sleeve bearings, white metal bearings and
journal bearings.

Averaging is possible in ‘point’ measurements such as ‘Multipoint’ and ‘Static mode’.

Measurement quality

Measurement quality is depicted using the following colour codes:
Blue – excellent; Green – acceptable; Yellow – not acceptable; Red – poor

Measurement quality is based on the following measurement and environmental criteria:

l Rotation angle – the angle through which the sensor and/or shaft is rotated during meas-

urement

l Ellipse standard deviation – the root mean square deviation of the measurement points

on the calculated ellipse

l Environmental vibration – the level of external vibration e.g. from neighbouring running

machine(s)

l Rotation evenness – the smoothness of the measurement rotation e.g. if there is any fric-

tion during the rotation that ‘jerks’ the shaft

l Angle rotation inertia – abrupt changes in the measurement rotation speed e.g. releas-

ing and re-applying a break during the rotation

l Rotation direction – change in the measurement rotational direction
l Rotational speed – how fast the sensor and/or shaft is rotated during measurement
l Filter output – the amount of measurement data filtered out

Editing measurement data

To improve the quality of the alignment results, it is possible to edit measurement data that
could have been affected by external circumstances such as bracketing touching piping
arrangement. The editing options are accessed via the measurement table.

When in the measurement table screen, tap desired measurement (1) then tap (2) to
access the measurement data screen.

Broken ellipse

The most commonly used deviation diagram is referred to as 'broken ellipse'. During meas­urement, the laser beam traverses an arc that is dependent on the alignment condition of the
rotating shafts. Over a complete 360° rotation, the beam describes an ellipse. Cutting the
ellipse and laying it out flat results in the deviation diagram 'broken ellipse'. In this diagram
points out of track are clearly seen.

94 Version:2.3

On-board help

All deviation diagrams show the actual number of active and inactive points, the current stand­ard deviation (SD), and the total change in standard deviation (delta SD) when deviant points
are deactivated.

What is the effect of deactivating individual points?

Individual points are deactivated in order to lower the standard deviation value. Change in
standard deviation impacts the V and H results displayed in the results repeatabilty table. Res­ults with a green check mark indicate results with better standard deviation.
