Preparation
Prior to beginning the installation the machine should be studied to determine the Encoder(s) position and to
ensure the brackets are suitable, or if custom brackets are required.
In order to reduce erroneous readings caused by machine wear it is recommended that the encoder be tted as
close to the machine lead screw or axial drive shaft as possible.

If for any reason the machine axis travel is greater than the actual scale travel, ‘mechanical stops’ should be
tted to the machine to avoid damage caused by over-travel. Newall will not accept responsibility for encoder
damage caused by machine over-travel.
It is important the Scale be kept at least 13mm (0.5”) away from any magnetic sources such as magnetic bases
or chucks.

Reader head alignment
Scale mounting - double ended
Scale mounting - single end (300mm (12”) travel or less)
Mounting faces
The reader head can be mounted on any 3 of the faces shown in g 3.
Alignment tolerance to machine
The reader head should be mounted with both planes parallel to the axis of travel within ± 0.05mm (0.002”).
See g 4 and 5.

Traverse the machine to its maximum position towards the non cable entry side of the reader head. Slide the
scale through reader head and t assembly (g 6 & 7) onto end of scale. Mark the position of the pillar.
Drill & tap to suit pillar (g 1 & 2). Loosely t assembly to pillar, pass scale through, slide scale forwards and
back whilst tightening the screws until it passes smoothly through head and bracket. Once aligned repeat at the
other end.

For Spherosyn300 remove the white nylon snap rivet from end of the scale.
Once reader head is aligned, slide the scale through and into the single end support and secure into place.
Position the block in the correct position, mark the slot. Drill & tap to suit xing (g 8 & 9). Once secured check
alignment by gently sliding scale in and out through head and block. Grub screws are available for adjustment.
You can single end mount with the standard link, pillar brackets or with the optional single end mount brackets
shown above.
Fitting the scale guard
Cable routing
Final check
Care should be taken to ensure that all cables are routed and secured to the machine avoiding any mechanical
interference with any part of the machine or encoder movement. Routing should also avoid sources of electrical
noise and interference. Cable clamps are supplied.
Note: The armoured cable is an integrated part of the reader head. If the cable becomes damaged this will
require a replacement reader head. Ensure all connectors are located in a position to avoid uid contamination.
Each Encoder includes a protective guard. The guard can be attached to the machine casting or by means of
the scale support pins via the button head screws provided.
For single end mounting use machine faces.
After the guard is attached, move the machine axis to both extents of its travel ensuring that the guard does not
interfere with or rub against the Reader Head.
Prior to putting the linear encoder system into operation after installation, slowly traverse the machine axis to
ensure that all cable routings are correct and machine over-travel cannot occur.
