    20th century. Now there is the ZTC 505 Digital Controller, with RealFeel™ controls that look and perform like the real controls of a traditional locomotive.
  • Page 6 Multiple Train Control One ZTC 505 can command up to 12 locos in motion at any one time from up to 9,999 different loco numbers. A roster is maintained of the currently running engines so that only one button press is needed to swap between each one.
  • Page 7 ZTC Controls Ltd. 505 Manual How the System Works To use the ZTC System you do not need to know any of the technicalities, but the basics are: - The actual voltage on the track is in the range of 12 to 24 VAC according to the gauge or scale requirements.

  • Page 8: Connecting Power To The Ztc 505

    To prevent short circuits an insulated joint must be placed at the entry and exit of the loop. However, if the loop section is fed by a ZTC power booster (ZTC 550), continuous running will be possible through the loop. The booster senses the polarity of the track signal needed and automatically switches itself at either the entry or exit as the train passes the insulated joint.

    The regulator lever is used to control the speed of the loco. Its immediate affect on the speed of a loco depends on other settings of the ZTC 505 and the settings of the decoder module in the loco concerned.

    TRACK 3.0 Liquid Crystal Display (LCD) The ZTC 505 comes equipped with a display unit that plugs into the back of the ZTC 505. The display unit can be tilted by loosening the two Display Tilt Adjust screws located on either side of the Display Unit with your fingers.

    CURRENT 3.3 Overload The ZTC 505 is equipped with overload protection in the event that a short circuit occurs. On detecting a short circuit, track power is momentarily turned off. The OVERLOAD lamp will light when this happens and a "beep" will be heard. If the short circuit is cleared, then power will be automatically restored.

    Depending on the loco control mode (14, 28 or 128 steps – see Section 5.1) Once set, the above settings are stored in the ZTC 505 and do not need to be set again, unless a change is required.

  • Page 17: Operating Our Ztc 505

    For new decoders use the number 3 which is the default value. 5.1 Loco Control Mode The ZTC 505 can be configured to send speed control signals to a loco decoder in one of three modes. These are the 14 step, 28 step and 128 step modes. The higher the number of steps, the smoother and more precise the speed control.

    LOCO ENTER R running, but the ZTC 505 controls are now assigned to the other loco number. However, the newly assigned loco can only be controlled once the regulator has been moved to the OFF position, and the reverser lever has been returned to the MID position and then moved to FWD or REV as required.

  • Page 19: Switching Control Between Running Locos

    ZTC 505 will search for the first loco that is halted, delete it from the roster, and then add the new loco to the roster. If all 12 locos are in motion, the system will halt the first loco in the roster, delete it, and then replace it with the new loco number.

    Alternatively use a separate lead from the same transformer as used for the Master ZTC 505 controller. In this case you will need to add a second connector to the output of the transformer wired the same way round as the first.

  • Page 23: What You Need To Know About Loco Decoders

    ZTC Controls Ltd. 505 Manual 7.0 What You Need to Know About Loco Decoders For independent operation of several locos on the layout, each loco needs to have a loco decoder installed (except loco 0, see Section 5.3). A loco decoder contains a miniature computer chip that responds to commands (speed up, slow down, turn on lights, etc.) sent...

    The method of resetting ZTC loco decoders to factory settings. The method used depends on the type of decoder concerned. 7.8 ZTC 203, 205, 206 , 213, 214, 215, 216, 217, 218, 226, 227 and 251 Reset these decoders using the following keystrokes: ENTER R →...

    It can only be found by experimentation for a given model. On ZTC decoders, numbers 0 to 255 are possible although if it needs numbers above 100, it would suggest that the model has considerable friction! Other makes of decoder may use different values for this CV (see decoder instructions).

  • Page 27: Cv 3 And Cv 4 Loco Acceleration And Deceleration

    On ZTC decoders the range is 0 - 255 with 255 being the full power value. If zero is ever set the loco will never move. A lower practical limit is about 32 for very sensitive motors.

    7.17 CV 29 Basic Configuration Register The default value for CV 29 for ZTC decoders is the value 2. If you get the motor wiring the wrong way round (setting the ZTC 505 to a forward direction results in the loco going backwards), it can be fixed without rewiring the loco by changing the CV value to 3.

    The unit should be returned to ZTC for re-calibration. 10.3 Transformer Test The ZTC 505 is able to estimate the voltage of the transformer powering it, to determine if the voltage value is in an acceptable in range. This is performed by pressing the following keys: →...

  • Page 40: Installation

    505. THIS WILL RESULT IN AN ELECTRIC SHOCK HAZARD AND WILL DESTROY THE UNIT The input power requirements of the ZTC 505 is low voltage only. Never attempt to directly connect live mains supply to the unit. A low voltage mains transformer or power supply must be used.

  • Page 41: Input Terminals

    As an alternative, an external DC low voltage power supply can be used to power the ZTC 505 using the G (ground) and +P (+ve power) terminals. It should be 12 to 24 volts, regulated DC only. A capacity of 1.5 9-17 VOLTS to 5 amps will be needed depending on your operational requirements.

  • Page 42: Recommended Track Wiring Gauge

    So it is better to use the heaviest recommended gauge wire for the job at the outset. See the table for more information. ZTC supply a self adhesive copper tape (ZTC 320) which is rated at 20 Amperes and ideal for all gauges. A flexible connection cable (ZTC 100), rated at 10 Amperes, is also available.

    2. It can therefore feed any separate siding, stub, or through track on your layout. In the programming mode of operation, an internal relay within the ZTC 505 disconnects the rest of the layout and only the programming track remains energised at a low power level. This allows the set-up of a loco with decoder when it is placed on this special section.

    The loop must be Isolated at both ends However, if the loop section is fed by a ZTC 550 power booster, continuous running will be possible through the loop. The booster senses the phase of the track signal needed and automatically switches itself at either the entry or exit as the train passes the insulated joint.

    CLEAR 15.2 Physical Register Mode In Paged Mode, some older non ZTC makes do not page properly nor will they work in the Direct Mode. Their physical registers (the equivalent of CVs) can all be directly accessed by keying numbers 2001 to 2008 to correspond to 1, 2, 3, 4, 5, 6, 7 and 8. The decoder programming is then the same as for Paged Mode using these +2000 CV numbers.
