System Connection - Renishaw TONiC DOP Installation Manual

System connection

Approved ESD precautions must be followed at all times during
readhead and interface electrical connections.
The readhead is connected to the DOP interface via a small,
rugged connector to allow for easy feed-through
during installation.
Connecting the readhead
Remove the cover plate as shown
u
(2 x M2.5 hex head screws).
Taking care not to touch the pins, plug the
u
connector into the socket in the interface,
ensuring correct orientation as shown.
Refit the cover plate ensuring the cable ferrule
u
is located in the recess on the inside and
no wires are trapped under the cover plate.
Disconnecting the readhead
u Remove the cover plate on the interface
(2 x M2.5 hex head screws).
Gently lever the connector PCB (on the end of the cable)
u
out of the socket.
Place the connector in an anti-static bag.
u
Refit the cover plate.

Readhead mounting and alignment
Mounting brackets
The bracket must have a flat mounting surface and should enable conformance
to the installation tolerances, allow adjustment to the rideheight of the readhead,
and be sufficiently stiff to prevent deflection or vibration of the readhead during
operation.
Readhead set-up
Ensure that the scale, readhead optical window and mounting face are clean
and free from obstructions. To set nominal rideheight, place the readhead spacer
with the aperture under the optical centre of the readhead to allow normal LED
function during set-up procedure. Adjust the readhead to maximise the signal
strength and achieve a green set-up LED on the readhead (70 to 135% signal).
Aim for a blue LED on the interface.
NOTE: The readhead should be installed and set-up with the AGC switched off.
