DCC / ANALOG TURNTABLE
1. Introduction
Dear Customer!
Thank you for purchasing the “HELJAN DCC / Analog Turntable”.
Your new HELJAN Turntable has many features; therefore it is important to carefully read this guide before
installing it on your layout. The turntable is like a small computer, working on very small voltage / impulses,
therefore it is important always to keep the moving components (gears, optical eye etc.) very clean.
HELJAN has produced a turntable that meets all the requirements needed for a modern DCC layout.
If installed and used correctly, this product will give years of service!
2. Before you get started
a)
Your turntable should be powered from its own transformer (not included).
Check the output of the transformer is correct for this use before making any electrical connections.
The ideal voltage to operate the turntable is 15v AC, 500 mA.
b)
The opening in the wall of the pit houses the optical sensor and is used as the ``zero point´´.
For the indexing to work properly, this area and the small gear teeth and ring rail moulded in the bottom of the
pit, must be clean and open at all times. If you wish to paint or weather the pit further, mask off these areas
before starting. Please note that it´s not possible to make a position directly at the ``zero point´´.
Before installing the pit, cover the centre pivot hole with tape to keep out dust and debris.
Your new turntable must be installed on a flat, stable and level surface. Determine the location for your pit and
use the enclosed template to cut the mounting hole in your baseboard. Allow at least 2¼´´ (5.7 cm) of clearance
below the pit. The zero reader is mounted directly below a mounting boss; be sure to provide clearance in your
baseboard for the reader too.
Pre-drill the positions for the mountings as shown on the template with an 8 mm bit. Secure the pit in place using
eight screws and washers (not included) - do not over tighten as this could cause the pit to warp.
If you are using foam / polystyrene for the surface of your layout, open the areas for the mounting bosses slightly
and push the pit into place.
Make sure the pit is level, secure and properly supported before proceeding.
When you have removed the bridge from the pit, it´s important that the power is switched off.
3. Adjustment of tracks
With the pit in place, you can install the approach/exit tracks. The indexing can be programmed for up to 48
different stopping positions, so you can add tracks almost anywhere around the pit – but remember, don’t install
tracks in the ``NO TRACK´´ areas.

DCC / ANALOG TURNTABLE
The bridge is equipped with a Code 83 rail-profile; if you are using another profile for your track, use of transition
tracks may be necessary. The top of your rails and the bridge rails must be level.
For a smooth transition between the bridge and service tracks, you need to modify your rails by filing the inside
at a slight angle for about 3/16´´ (4 mm) (see Fig. 1).
For the rails to sit correctly on the lip of the pit, you must
remove a few sleepers from the end of the track.
Remove with a file
Important note: Leave a gap of about 1/16´´(1.5 mm)
between the end of each service track and the bridge.
All service tracks must align with the bridge rails in a
straight line. The bridge can be used as a guide.
Wire the service tracks (parts not included) for power as
desired.
You must fix the position of your service tracks, before you program the positions.

4. Connection – Wiring-diagram
a)
Please note that your DCC Turntable automatically reverses the track polarity in the “ No Track” area. It is
therefore important that you are aware of the polarity over and under the “No Track” area.

b)
All red wires should be connected.
All blue wires should be connected.
If a short circuit occurs when the loco is running onto the bridge, the wires in screw terminal 1 and 2 should be
reversed.
c)
Finish by vacuuming and cleaning your Turntable.
Clean the contacts in the pit and on under the bridge. See Fig. 4
Contact under bridge: Clean in Propyl Alcohol or similar
and finish by wiping with a dry cloth.
Contacts in Pit: Clean in Propyl Alcohol or similar. Use a
cotton bud and be careful, not to bend the contacts,
because this may affect the contact to the bridge.
It is important that the power is switched off when you
clean the contacts

5. Functions and overview of the Control Box
a)
Operational overview
The electronic control integrated into the Control Box for the turntable has the following characteristics:
Analogue and digital operation
The turntable can be used on analogue model railway layouts as well as digital model railway layouts run in DCC
format. In analogue operation the turntable is run via the control box. In digital operation it is possible to remotecontrol the turntable from a digital control unit via the Control Box.
The electronic control automatically recognizes the operational mode (analogue or digital) and the digital format
DCC that is run.
Settings
The electronic control allows you to define up to 48 individual stops of the bridge.
Please note: Stops can be added or deleted separately at any time. Also please note, that when a
position/stop is set, a 180 degree position/stop, from current position, is automatically set.
Running
The motor running the bridge is driven with a starting and braking delay that replicates the
operational characteristics of the prototype.

6. Finish by calibrating. See Section 6B.
b)
Calibrating the bridge / menu point
The bridge will automatically calibrate itself, when travelling past the zero position during
normal operation. The zero position is where the sensor is located in the side of the pit.
However, there are times when you have to calibrate the bridge
(See section 5D `Menu of the control box´ for more information).
To calibrate, follow these instructions:
1. Scroll to the menu point
.
2. Press the function key ``GO/SET´´. ``Cal´´ in the display starts to flash.
In case you want to cancel, press ``ESCAPE´´.
3. Press the function key ``GO/SET´´ again ``Cal´´ in the display flashes half as quick as before.
The bridge will start to turn first slow, then fast until it reaches ``0´´-position and then stop at the pre-installed
position 1.
Please note, If the bridge does not stop at position ``1´´ after calibration a counting error has
occurred and the bridge needs to be calibrated again.
c)
Setting a programmed stop of the bridge / Menu point
1. Scroll to the menu point ``Prog´´.
2. Press the function key ``GO/SET´´. ``Prog´´ in the display starts to flash. In case you want to

3. Start the bridge moving by pressing the function keys ``UP´´ or ``DOWN´´ for a short time.
To stop the bridge at the selected position press the function keys ``UP´´ or ``DOWN´´ again.
The fine tuning of the position can be done with the ``UP´´ and ``DOWN´´.
Attention: Always finish positioning the bridge in the same direction you started programming in.
4. Save the chosen position by pressing the function key ``GO/SET´´ again.
5. ``P´´ in the display is shown and the highest available number for a position is suggested
in the display. If necessary choose a lower number by pressing the function key ``UP´´ or ``DOWN´´.
Selecting a lower number is equal to inserting a position between already programmed positions. This implies
That all programmed positions above the point of insertion is incremented by one position number.
6. Save the chosen number by pressing the function key ``GO/SET´´ again.
7. Finish by calibrating the bridge. See section 6B.
Special feature: Please note, that when a position/stop is set, a 180 degree position/stop, from current
position, is automatically set.
NOTE: It is not possible to make a position directly at the ``zero point´´.
Note: If you accidentally push the ``GO/SET´´ when you wish to stop at a desired position,
the display flashes with a suggested position number. Press ``ESCAPE´´. The bridge stops and
the display shows ``Prog´´ .Push ``GO/SET´´ and then the ``UP´´ or ``DOWN´´ function keys
twice and find the correct position. Always stop with ``UP´´ function key.
Please note: The program does not allow to leave out a number for a stop. Example:
You have already four stops (which have been assigned the numbers 1 to 4)
You want to set a new stop (the fifth)
Either
no. 5 (which is suggested automatically)
Or
a lower no. (1, 2, 3, 4)
In case you choose a lower number (e.g. no. 2) the program automatically renumbers the stops
As shown below:
New stop
Old stops
Stop numbers before setting the fifth stop
Stop numbers when setting the suggested
number for the new fifth stop

NOTE: Positions 1 and 2 (are related to the zero point) are not programmable positions; start with track 3 when
you program tracks. When you have made minimum 2 new stops, you are able to remove the
pre-installed position 2. Also please note that it´s not possible to make a position directly at the ``zero point´´.
d)
Deleting a programmed stop of the bridge / Menu point
In order to delete a position of the bridge follow these steps:

DCC / ANALOG TURNTABLE
1. Scroll to the menu point ``del´´
2. Press the function key ``GO/SET´´
3. Press the function key ``GO/SET´´ again. The display shows a ``d´´
and the number of your current stop. If you want to delete another stop than the chosen one, simply choose
another by pressing the “UP” or “DOWN” buttons. Please note that deleting a position causes all positions
above the deletion point to be decremented by one position number.
4. Delete the chosen stop by pressing the function key ``GO/SET´´ again.
All positions with a number higher than the deleted one are renumbered automatically.
Please note: After completion of deleting desired positions, the display always returns to show Tr 1.
7. Driving the bridge to a programmed stop / Menu point
In order to change the bridge’s position, follow these steps:
1. Scroll to the menu point ``tr´´. The digit no. shows the current position of the bridge.
2. Press the function key ``GO/SET´´. ``tr´´ in the display starts to flash.
In case you want to cancel, press ``ESCAPE´´.
Remark: In order to avoid involuntary changes of the bridge’s position by pressing the function
keys ``UP´´ or ``DOWN´´ by accident you need to press the function key ``GO/SET´´ first before
choosing a new position for the bridge. When just pressing the function keys ``UP´´ or ``DOWN´´
you will scroll from one menu point to another.
3. Press the function keys ``UP´´ or ``DOWN´´ to choose the number of the track position to go to. Only the
numbers of stops that have been programmed are shown.
4. Press the function key ``GO/SET´´ again. ``tr´´ in the display flashes half as fast as before
and the bridge will move to the next track position.
Please note: If the bridge is already at the selected position number and you’ve gone all the way to step 4, then
The bridge will do a 180 degree turn from its current position.
8. Maintenance
As operation can be affected by dust, it is recommended to cover your Turntable between operating sessions.
Zero Point: Make sure this area and the pit edge is always clean and free of dust.
84089121
Page 9
WWW.HELJAN.DK
DCC / ANALOG TURNTABLE
Use Propyl Alcohol or a similar cleaner to clean the contacts on the bottom of the bridge and in the pit, should
they get dirty.
Important note: Any time the bridge is removed from the pit, you must calibrate (see 6B) before resuming
operation in order for the bridge to find the positions correctly.
Lubrication: In normal use, the drive mechanism should only require servicing about once a year. Use plastic
compatible lubricants made especially for hobby products – NEVER use household oils or lubricants!
Remove the screws from the cover. Apply a drop of light oil to both motor bearings and the drive gear train. (See
Fig. 5)
Reverse these steps to reassemble – make sure the motor leads are positioned as shown.

9. FAQ
If the bridge doesn’t stop at programmed position and won’t move again or the control box
reads ``C´´:
Proper contact is not being made between the wipers and the bridge centre post. See 4C for cleaning contacts
and finish by Calibrating, see 6B.
If the bridge, in “Prog. Mode”, is running much slower CCW than CW:
It is recommended to let it run at least 1 turn CCW in “Prog. Mode”. Then the mechanical parts will be more
flexible.
When driving the bridge to another stop the bridge does not stop exactly at the set position:
1. Possible cause: The bridge has been removed from the pit or its position has been altered by hand or the
power supply has been interrupted while the bridge was moving or a position has just been programmed.
Calibrate the bridge again (see section 6B).
2. Possible cause: When setting a new stop the positioning of the bridge was not finished in the same direction
it was started. Due to technical reasons this does not allow an exact re-finding of the position. Delete the position
and set it again (see chapter 6D).
The display in the Control box reads Err1:
There is no contact to the bridge. Please try to clean the contacts as described in the Installation Instructions,
section: Troubleshooting. Also please check the wire-connection.

In DCC Mode: If the DCC Command station does not respond. Make sure the Control Box is set to Tr
mode.
10. DCC Uhlenbrock / Lenz / ESU
a)
The Turntable is compatible with the official NMRA Digital Command and Control (DCC) standard.
The turntable is connected to your layout by connecting the control box terminals directly to
the Booster output of your main control station. The connection details are depicted in figure 3, page 4.
In case of a short-circuit, when driving a loco onto the bridge, the wires connected to the turntable control box (1
and 2) need to be swapped.
The control box comes with a default accessory value of 057 (see section 10b for changing the default set digital
value) and it occupies the next 25 sub-addresses. Please mind that no other accessory decoder should be
located in the range covered by the control box. Please note that the accessory decoder address has no
influence on the loco address.
Please note: The set value is not identical with the digital address (as this is an accessory decoder´s address).
From the factory there are two preprogrammed positions on the turntable (1 and 2):
This means that track 1 will be assigned address 225 Red/curve, track 2 will be assigned address 225 Green/
straight.
Track 3 will be assigned address 226 Red/curve, track 4 will be assigned address 226 Green/ straight.
Now you'll be able to control the turntable like any other accessory decoder on your layout.. While controlling the
turntable from your digital control unit, the control box will depict which track position the turntable is turning
toward, (this requires that the control box menu is set in “tr” mode.
Furthermore can computer software you may wish to use to control your main layout, also control the turntable.
Setting the turntable’s digital address / Menu point
b)
In order to set the turntable’s digital address, follow these steps:
1.
Scroll to the menu point “Adr”.
2.
Press the function key ``GO/SET´´. “Adr” in the display starts to flash. If you want to cancel, press ``ESCAPE´´.
3.
Press the function key ``GO/SET´´ again. The display shows a flashing “A” and the 3-digit number of the current
address.
4.
Choose a new value by pressing the function keys ``UP´´ or ``DOWN´´.
Advice: The keys have a repeating function: When pushing them for a longer time the values are not altered one
by one but very quickly.
5.
Save the chosen value by pressing the function key ``GO/SET´´ again.
Please note: The set value is not identical with the digital address (as this is an accessory decoder’s address).
c)
Further information regarding changing the control box's accessory address:
First of all you need to find the address to assign to the included control box. This is accomplished by finding the
desired accessory sub-address and performing the following calculation:
84089121
Page 11
WWW.HELJAN.DK
DCC / ANALOG TURNTABLE
57x4=228. Accessory address = ( (DCC Address - 1) * 4 ) + 1
for example if DCC Address = 57 then
Accessory Address = ( (57-1) * 4 ) + 1 = 225.
Please note that the bridge already has the digital address set to 57, so no calculation is need, unless you wish
to change the address.
Please note: The Control box must be in the “Track mode” (Tr must be displayed on the Control Box) in
order to be able to drive the bridge from track to track via the digital command station (DCC).
Please note: The Control box supports both state-full and state-less, also referred to a permanent and
momentary – accessory decoders.
d)
The lowest accessory address selectable on the control box is 1, this yields accessory subaddress 5 for track position 1 and 1017 for track 48.
The highest accessory address selectable on the included control box is 248, this yields accessory sub-address
993 for track position 1 and 1017 for track 48.

On a DCC System that has multiple options other than DCC (like Intellibox from Uhlenbrock), the accessory
decoder settings should be set for DCC.
If the booster shuts down (eg. short circuit on the track), while the Turntable bridge is running, you may need to
calibrate the Turntable (see section 6b, page 8) to restore accuracy.
