User manual

Remarks: The decoder addresses for magnetic accessories
are combined in groups of four. The addresses 1 to 4 build
the first group. The addresses 5 to 8 build the second group
etc. Each 1-DEC-DC decoder can be assigned to any of
these groups. Which turnout of a group will be activated for
the addressing does not matter.
• If the decoder has recognized the assignment correctly the
connected turnout will move a little faster. Afterwards the
movement slows down to the initial 1,5 seconds again.
In case the decoder will not recognize the address it could
be that the two digital information connections (clamp 2) are
wrong way connected. For testing this, switch the power
supply off, exchange the connection on KL2 and start
addressing again.
• Leave the programming mode by pressing the programming
key S1 again. The decoder address is now permanently
stored but it can be changed at any time by repeating the
programming as described above.
• If you press now the first key of the programmed group of
keys or you send a switch signal for this turnout from a PC
the addressed turnout drive should move into the called
direction (round or straight) until end stop. In case the
movement goes in the wrong direction please exchange the
turnout connection.
Switching turnouts via loc-addresses
(Lokmaus 2® or R3®):
The decoder 1-DEC-DC can also control turnouts via loc-
addresses. For example with the functional keys F1 to F4 of
the Lokmaus 2® or R3®.
The turnout connected to output 1 will be switched with the
functional key F1 and the turnout connected to output 2 with
key F2 etc.
Each pressing of a functional key will release a movement of
the respective turnout from turning to straight or vice versa.
To program the loc-addresses a turnout drive has to be
connected to the output 1 (clamp KL9) of the decoder.
• Switch on the power supply of your model railway.
• Adjust the speed of all connected speed controller
respectively all lokmauses to zero (center position of the
adjusting dial).
• Press the programming key S1. Do not touch the
integrated circuits of the pc-board because any electrostatic
discharge can destroy the IC`s.
• The turnout drive connected to output 1 will now move every
1,5 seconds. This indicates that the decoder is in the
programming mode.
• Now adjust the required address on one Lokmaus and turn
the speed control dial away from the center position. If the
decoder has recognized the assignment correctly the
connected turnout will move a little faster. The decoder
1-DEC-DC will accept loc-addresses between 1 and 99.
• Adjust the speed control to zero again. The movement of
the connected turnout will slow down to the initial 1,5
seconds.
• Leave the programming mode by pressing the
programming key S1 again.
• If you press the functional key F1 the turnout connected
to output 1 will be switched over by each key stroke. In
case some further turnouts are connected to output 2 to 4 of
the decoder 1-DEC-DC this turnouts will be switched with
the functional keys F2 to F4 with each respective key stroke.
Attention:
• Each of the 4 decoder outputs can switch 1 Ampere max.
For securing the decoder components and the connected
turnout drives the decoder 1-DEC-DC includes an
overload fuse. This is an automatic fuse which will switch
back to normal operation with a few seconds delay as soon
as the current load will be below the maximum value.
Accessory:
For the assembly of the 1-DEC-DC below your layout base
plate is our assembly set MON-Set recommended. For the
ready assembled kits and the finished modules from version 2.0
we offer a suitable case under the order code LDT-01 a suitable
case with the dimension of 93x80x32mm within our program.
If you require for an outdoor application a suitable splash-
water protected case for the 4-fold turnout decoder 1-DEC-
DC from version 2 we can offer you a suitable case of the
dimension of 125x85x55mm under the order coder G-2-DEC.
You will receive this case together with a splash-water
protected cable inlet.
Trouble shooting:
What to do if something is not working as described above?
If you have purchased the decoder as a kit, please check
carefully all parts and soldered joints.
Here some possible functional errors and possible solutions:
1. During programming of the decoder addresses the turnout
moves within 1,5 seconds, but does not confirm the
programming with faster movement by pressing any key.
• Change cable connections at KL2.
• Interfered digital information at KL2 respectively larger
lost of voltage at the tracks! Connect the decoder directly
with cables to the digital control unit or to the booster
instead to the tracks.
• For kits: Is IC5 correct inserted into the socket? Has
resistor R6 actually 220kOhm or has this resistor been
mixed-up with the 18kOhm resistor R5?
2. The programming of the decoder address functions as
described, nevertheless the connected consumers can not be
activated.
• Interfered digital information on KL2 respectively larger
lost of voltage at the tracks result to unsafe data transfer!
Connect the decoder directly with cables to the command
station or the booster.
• For kits: Is IC4 correct inserted into the socket?
