Range Of Applications - roco 10727 Bedienungsanleitung

Please note:
The control unit, art.-no. 10727, was particularly developed to be used together with the 8010727100. It
is also possible to operate the control unit 10727 with the transformers 10718 or 10725 (fig. 1-3). Then
it must be observed however that because of the higher output voltage the locomotives would travel a
bit too fast compared with the original.

Range of applications:

Pulse duration controlled power supply with infinitely variable speed control for d.c. traction cars.
Start-up
The control unit is primarily intended to be used together with the transformer, art. no. 10718, 10725
and 8010727100, which supplies a voltage about 15V. On the rail plug of the control unit has a pulse
duration controlled power supply with an infinitely variable d.c. voltage of max. 18 V (maximum pulse
amplitude). (fig. 4)
1. Supply plug
Please connect the transformer to the supply plug. (fig. 1-3)
2. Rail plug
Please connect the rail to the rail plug. (fig. 1-3)
3. Knob
The Knob is used to select the direction for the locomotive and to infinitely control its speed: the farther
the knob is turned from the middle position, the higher the locomotiv's speed. The power supply is
turned off in the middle position (0 – position) and the control unit disconnected from the track system
(or the overhead lines). The knob is also used to reset the short-circuit detection by turning it to middle
position.
Note:
Because of your control system, pulse with controlled drive controllers are not suitable for bell-type
armature motors with air-cored armature (examples Faulhaber, Escap, Canon and others); the use of pulse
with-controlled drive controllers with bell-type armature motors can cause irreparable damage to this
type of motor.
Since the control unit does not have a built in contact separation between the supply voltage and
the regulated output voltage, more than one control unit may be operated with a mutual transformer
if all of the cars in your set are operated via a sub-line only or an overhead line only. Troublefree
operation of mixed sub-line and overhead line systems will only be possible if each control unit
(whether overhead or sub-line) has its own transformer. For mixed operation, a grouped power sup-
ply (i.e. all control units for sub-line using one transformer and all control units for overhead lines
using another transformer) will cause reciprocal interference between the various electrical circuits
and therefore unpredictable reactions between the cars. If all-sub-lines or all-overhead lines are
used, several control units may be connected to a mutual transformer. Both poles of the individual
electric circuits must, however, be isolated (for all-sub-lines operation insulating rail bonds in both
rails, for all-overhead line operation also in the overhead line).
