Installing Carriage Switch
Fit carriage switch terminal block assembly to the left-hand
side of the cassette (Fig. 28), using the fasteners supplied, to a
torque of 5Nm. Stick the designator label next to terminal block
assembly (Note: Two terminal locations are unused).

Fit the ‘flexform’ grommet strip into the aperture in the lower
left side of cassette (Fig. 30) and feed cables through.
Position carriage switches to cassette floor over the two
tapped holes and loosely fix with two M4 x 6mm screws (Fig
29).

Insert racking handle and rotate clockwise until the racking
drive stops. The racking indicator will read CONNECTED.
Place setting gauge in position and hold firmly against forward
face of racking drive. Adjust the position of the carriage switch
until the upright face on the clear plastic moulding is just in
contact with the gauge (Fig 32). Fully tighten fixing screws to
5Nm.

The standard configuration is two switches for each position as
illustrated above (Fig. 33).
Note, the carriage switch will maintain a disconnected
indication even when the ACB is fully withdrawn or removed.
The 6 circuits may be re-configured by customer to give up to
3 at DISCONNECTED, 6 at TEST or 6 at CONNECTED - in
any combination up to a 6 circuit maximum. Configuration
procedure is as follows:
•
Unhook the return springs, first from the carriage switch frame
and then from the clear plastic moulding.
•
Remove 2 off M4 x 6mm carriage switch fixing screws (if fitted
to the cassette base) leaving the carriage switch held in
position by the wiring.
•
Lift the carriage switch slightly and slide out the moulding from
the rear of the assembly.
•
The trip pins on the moulding are snapped in from its
underside
and can be pushed out using fingers or an
appropriate screwdriver in the slot between the retaining legs.
•
Reconfigure by snapping the pins back into the required
locations ensuring that the head on the trip pin is radially
located in the adjacent slot (Fig. 33).
•
Slide moulding fully back into carriage switch frame and
reconnect the
left hand
return spring.
•
Reset the position of the carriage switch as described above.
•
Reconnect
the
right hand
return spring.
