Installation Requirements - Roco LINE Mode D'emploi

Contents of Set
The following parts and assemblies are included in the turntable set as de-
livered:
• 1 turntable pit, equipped with complete bridge (including motor shed,
imitation of hand crank with locking lever, etc.), permanently installed
under-floor drive, complete 360° attached concrete filler pieces with 24
pieces 9° and 24 pieces 6° segments, without access tracks.
• 1 package art.no. 42616 with four access tracks for 2-rail 2-conductor
DC layouts; (*)
• 1 bag with 12 pieces 3° and 12 pieces 1° filler pieces;
• 1 bag with 2 simulated bridge signals and two contact coil springs for
position indication of the turntable bridge;
• 1 manual control unit;
• 1 Power distributer
• 1 8-conductor connecting cable turntable/manual control unit with 8-
pole flat connectors attached at each end:
• 1 5-conductor connecting cable manual control unit/control transformer
with 5-pole flat connector attached at manual control unit and ends

Installation Requirements

1) Power supply
a) Control and drive motor:
14-16 volt AC
b) Running current within the turntable area: same as used on the layout
everywhere else:
• either 0 -12/14 volt DC (international standard 2-rail DC system);
• or 0-16 volt AC (3-rail AC system with centre conductor; on access track
with centre-stud contacts, on the bridge with simulated ribbed sheet
metal cover between rails).
It is recommended to assign a separate control transformer to the turntable
and its surrounding operating area in both 2-rail DC and 3-rail AC systems;
the iltumination/ magnetic ar-ticle output terminatsof this transformer are
used for operation of theturntable and possible' illumination of the area,
while the running power output terminals are used to supply running power
on the turntable and surrounding areas. A control transformer with exten-
ded slow-speed range of the running power is particularly wellsuited (e.g.
ROCO 10704) since it permits very sensitive shunting.
2) Mechanical track standards:
a) Bridge
The rail profiles on the bridge are designed to accept wheel profiles accor-
ding to NEM (and MNRA) as welt as wheel sets used with 3-rail AC systems
which generally use higher wheel rims.
b) Access tracks:
As shown In the list of supplied items (page 5 of these instructions) the
turntable is factory delivered with a package art.no. 42626. lf the turntable
is to be used on a layout built with 3-rail AC track, the access track package
42616 (with four access tracks without centre studs) should be exchanged,
at time of purchase, against a access track package 42617 (containing three
access tracks with centre stud contact, as previously described in chapter
"Contents of Set" on page 5. In case of "K" track of the 3-rail AC system no
additional parts are required, for "M" track the system-specific conversion
tracks from "M" to "K" track must be provided additionally.

with insulation removed at the other end for attaching to the control
transformer:
• 1 four-colour instruction booklet (German language);
• 1 B&W, text only, manual (English).
(*) = The factory-delivered turntable contains one set of access tracks for
2.1 mm (code 83) 2-rail DC layouts. If the turntable is to be used for
a 3-rail AC layout your stockist will, at your request and without char-
ge, exchange the supplied package with 2.1mm 2-rail track against one
containing 2.5 mm 3-rail AC access tracks.
Please Note!
Only complete packages will be exchanged, i.e. one package art.no. 42616
against one package art.no. 42617, but not individual access tracks!
Also refer to the explanation of the intentionally different number of tracks
in art.no. 42616 (4 access tracks) and art.no.42617 (3 access tracks) in the
last paragraph on page 6.
The different number of access tracks in package 42616 (fig. 9, access track
for 2-rail DC layouts) and 42617 (fig. 10, access track for 3-rail AC layouts)
are not errors in packaging but compensate the difference in manufactu-
ring cost and selling price so that access track packages can be exchanged
against each other without price differential).
Notes:
a)
If the turntable is used on 2-rail DC layouts with 2.5 mm (code 100) pro-
file track (e.g. standard ROCO track system) where only rolling stock with
wheelsets conforming to NEM or NMRA standards are used, the access
tracks from package 42616 can be used. All access tracks which are directly
joined to 2.5 mm rails of the layout must be connected with the transfer
fishplates (rail joiners) 42612 (see fig. 11).
For simplicity it is recommended to use the ROCO LINE track without road-
bed for the connecting shed tracks which have no further connection to the
remainder of the layout even though the entire layout is set up with 2.5 mm
profile track.
b)
When using the turntable on layouts with hollow profile rails (especially
existing PIKO- or HRUSKA track systems) the transfer tracks 42414 must be
used instead of transfer fishplates (see flg. 12). The recommendation made
in a) above is equally applicable to the shed tracks.
c)
Use of the turntable on layouts with rolling stock having so-called "fine-
scale" wheelsets (RP 25 of NMRA) is possible without limitation or change
when using access tracks 41616.
3) Installation location:
To assure trouble-free operation of the turntable for many years it is impor-
tant to make sure that the area of the layout where the turntable will be
located is absolutely flat and horizontal. Only then is it possible to avoid
hardly visible twisting of the turntable pit during installation which will re-
sult in uneven movement of the bridge and unreliable operation!
