  1. questionBDL168 - Using with Power Managers
    The BDL168 is designed to be used with power management devices such as PM42. The BDL168 is designed to operate “downstream” of the Digitrax boosters and power management devices. The BDL168 is the "last" device in the chain from booster to power manager to BDL168. It is connected ...

  2. questionAutomatic Reversing and Turnout Control
    Q: How do I use the AR1 and automatically control the turnout? I'm confused here. It is good that the AR1 controls the switching of the track power for a reverse loop automatically but it seems the turn out direction also needs auto control. Am I missing something here? Need help understanding.. ...

  3. questionPM42 Short Circuit/Auto-Reversing Failure when used with DCS50 (Zephyr)
    PM42 Short Circuit/Auto-Reversing Failure When used with Zephyr (DCS50) The PM42 is designed to control 4 independent power subdistricts that can be set up as either a “Short Circuit Manager” (the factory setting) or as an “Auto-Reversing Controller.” The PM42 factory se ...

  4. questionPM42 - Programming
    On Page 9 of the instructions (under 5.0 Op Sw Set Up) I am to connect my DT400 throttle to my powered PM42 . . . 1. Does “powered” mean having the PS-14 power supply to the PM42 connected and energized? Yes. We took another look at the documentation and it means that the PM42 shou ...

  5. questionPM42 - Trip Timing
    My dealer told me that the when the PM42 changes polarity on a section of track, that it should remain that way till another "short" is detected. Mine will change polarity for about 1 - 1.5 seconds and then change back. Is this normal and my dealer told me wrong? Your dealer is correct. You ma ...

  6. questionPM42 - Local Annunciation
    How can I remotely monitor the input and output status of a section of the PM42 that is configured to act as a circuit breaker at a remote location? The final output stage, of each section, of the PM4 or PM42 is a DPDT relay. The contacts of this relay act in a similar fashion as the contacts ...

  7. questionCommon Rail Wiring and Converting the Clinchfield
    I'm helping a friend rewire an existing layout from analog to digital. You might be familiar with the layout, it is the original Clinchfield layout that Model Railroader built back in the late seventies, believe it or not. The layout, of course, is blocked for analog through DPDT switches which ...

  8. questionReverse Loops Galore
    We have designed a layout at my place with double main line with reverse loop at each end. Plus there is a branch line with two reverse loops that in one loop is connected to the main line. The main lines stay double track even at the split. The branch stays single with only one connection with ...

  9. questionHow do I mount the 44 pin edge connector boards?
    My question is: How do I mount the PM42? Do I need a special housing in order to mount it under table? It appears to me that mounting it flush against a surface would prevent, or make it extremely difficult, to attach the 44-pin connector. Digitrax manufactures three devices which have a 44-pin ...

  10. questionUsing PM42 to correct shorts caused by thrown switches
    Q: If my layout is experiencing short because of a thrown switch, how can you reset the switch using DCC? Many Digitrax operators use the PM42 Power Manager, which provides protection to four power sub-districts. One segment of the PM42 is used to control track switch power, with the balance b ...

  11. questionPM42 - Powering with PS14
    The installation instructions indicate that a PS14 be used to power the PM42. Is it necessary that I cut the wire from the PS14 so that is can be attached it to the 44-pin connector, or is there a male adapter available for the connection? Yes, currently you will need to cut the wire, strip t ...

  12. questionSuper Empire Builder Power Requirements
    The answer to this question applies to all Empire Builder sets including Super Empire Builder Xtra Q: I have just purchased a Super Empire Builder set. My expectations are for it to operate an N-Scale switching layout right now with future expansion to a larger N-Scale layout. I am a little con ...

  13. questionPM42 - Power Management of an Auto Reversing Section
    Q: What is the preferred way of protecting a reverse loop with circuit breaker management and still having automatic reversing? A: There are two ways of protecting a reversing section with a circuit breaker and reversing section controller. 1. Use one PM42 (circuit breaker manager) and one AR ...

  14. questionPM42 - Auto-Reverse Section Protection with Circuit Breaker Manager with a Single PM42
    Q: Can two sections of a single PM42 be configured to perform both the task of a circuit breaker and also automatic reverse section control for a single reverse loop? The PM42 can be configured so that one section of the PM42 is used for circuit breaker operation, feeding into another section o ...

  15. questionPM42 - Power Management Circuit Breaker Control
    Q: What is the basic configuration and OpSw settings for a section of the PM42 when configured for circuit breaker control? A: The PM42 is a 4 section multi-purpose device where each of the four sections can be individually configured to act as either a circuit breaker, or automatic reverse loo ...

  16. questionPM42 - Programming Op Switches with a DT300 Throttle
    Q: How do I program the PM42 Op Switches with a DT300 throttle? A: The PM42 OpSw settings are used to set up the PM42, adjusting the trip current, short circuit management (including sensitivity), and/or auto-reversing. Note: The factory default setting on all PM42 OpSws is “thrown&rdq ...

  17. questionPM42 - Automatic Reverse Section Control
    Q: What is the basic configuration and Option Switch (OpSw) settings for each of the four sections of the PM42 when configured for automatic reverse section control? A: The PM42 is a 4 section multi-purpose device where each of the four sections can be individually configured to act as eithe ...

  18. questionPM42 - Programming Op Switches with a DT400 series throttle
    Q: How do I program the PM42 Option Switches (OpSw) with a DT400 throttle? A: The PM42 OpSw settings are used to set up the PM42, adjusting the trip current, short circuit management (including sensitivity), and/or auto-reversing. Note: The factory default setting on all PM42 OpSws is “t ...

  19. questionPM42 - Programming Op Switches with a Zephyr (DCS50 or DCS51)
