1. Clean ends of scale and the area
where end clamps are to be fitted
using Renishaw scale wipes or
one of the recommended solvents
(‘Storage and handling’, page 3).
2. Thoroughly mix up a sachet of RGG-2 two
part epoxy adhesive and apply a small
amount to the underside of the end clamp.
4. Immediately position end clamp over the
end of the scale and push down to ensure
complete adhesion. Allow 24hours at 20°C
for full cure*.
3. The end clamp features two small regions
ofcontact adhesive. These will temporarily
hold the end clamp in position while the
epoxycures. Remove the backing tape from
either side.
CAUTION: Ensure that excess epoxy
iswipedaway from scale as it may affect
thereadhead signal level.
*To ensure scale end movement of typically <1µm, stabilise the system at least 5°C higher than the maximum customer
application temperature for a minimum of 8hours. For example: Customer application = 23°C axis temperature.
Stabilise the system at 28°C for a minimum of 8hours.

System connection
Readhead only (no interface)
The ATOM readhead is available in several variants:

Cable variant with a 15-way D-type connector

Cable variant with interboard connector

FPC variant
None of these readhead variants has an integral calibration (CAL) button. Provision should be made
in the customers’ electronics for momentarily connecting the CAL line to 0V to initiate the calibration
routine, switch AGC on /off or restore factory defaults. See page 36 for pin-out information.
Calibration is an essential part of system set-up that optimises the incremental signals and phases the
reference mark. See page 28 for information on the calibration routine.
For FPC variants
Ensure that the FPC cable being used has the following specications:

16core

Conductor pitch 0.5mm

Minimum exposed conductor strip length 1.5mm


NOTE: The FPC cable must be connected before tting the readhead lid. The lid is secured by the readhead mounting screws.
Approved ESD precautions must be followed at all times during readhead electrical connection.
System connection (continued)
3. Pull the FPC cable straight back to remove it.
CAUTION: Do not pull upwards or sideways as
this may damage the readhead.
2. Ensure locking lever is fully open before removing
the FPC cable.
2. Applying pressure to the whole locking lever,
push it down to lock the FPC cable in place.
CAUTION: Do not push the locking lever down if
no FPC cable is inserted as this will damage the
locking mechanism.
Removing the FPC cable
1. Placing your finger on the whole of the locking
lever, slowly lift it up and away todisengage the
locking mechanism.
CAUTION: Do not use tools such as screwdrivers
or tweezers to open the locking lever as this may
cause damageto the connector or pcb.
Inserting the FPC cable
1. Ensure the locking lever is up (open) before
fullyinserting the FPC cable into the connector.
CAUTION: Check correct orientation of cable
before inserting into the connector. Readhead will
be shipped with connector in the open position.
3. When the system has been connected, proceed
with‘Readhead mounting and alignment’, page 23
and‘System calibration’, page 28.
