QUICKFIX INSTALLATION HANDBOOK

a) Remove the front panel by undoing the
four M4 fixing screws on the front panel,
using the 2mm Allen key. Keep the
screws and washers together, washers
are essential to prevent damage to the
Level Crossing front panel membrane/
label. The front panel will just lift off (the
Signal Box unit may require gentle
prising to remove the front panel from the
inner edges of the case). An earth lead
will be attached to the Level Crossing
front panel and its push fit spade can be
pulled away from the tag of the panel.
b)
Remove the Card Pullers from their
stowage location on the right hand side.
A) Remove all eight M3
slotted head screws
(and their washers)
from the left hand
Connection Plate
and the Connector
Retention bracket.
This plate may be
lifted away from the
‘D’ connectors.
IMPORTANT:
THIS
PLATE MUST BE
REMOVED BEFORE
ATTEMPTING TO
PULL THE CARD
FRAME FROM THE
CASE. DO NOT UNDO THE FRONT
FOUR M6 SLOTTED SCREWS .
b) Loosen the four M6 hexagonal head
bolts (two each side of the case), using
the 10mm ring spanner. Remove the
lower bolts each side, then support the
frame with one hand whilst removing
the two upper bolts. Pull the frame (still
attached to the left and right brackets)
out of the case. Remove the remaining
earth tag, at the rear of the case, to
allow the frame to be separated from
the case. Carefully stow all of the
removed items.
