Dcs52 Error Messages; Decoder Speed Step Settings - Digitrax Zephyr Express DCS52 Manual

15.0 DCS52 Error Messages

The DCS52 displays several types of error messages:
1. Short circuit shutdown occurs when the DCS52 detects a short circuit in
the power district where it is connected to the layout. This can be a loco
that has derailed, picked a switch or some other conductive material lying
across the tracks. In this case you will see this message "Local Booster
Track Fault" will scroll in the Scrolling Help Text line. The DCS52 will
beep 3 times and the track status light will blink. Once the short is cleared,
the DCS52 will resume normal operations.
2. Input overvoltage: The DCS52 will display the message "HIGH Input
DC voltage" and beep continuously when the input power to the DCS52
causes the internal voltage level to exceed about 16.9V DC. The DCS52
is designed to operate with DC input power only with a PS314 power
supply.
3. Input undervoltage: The DCS52 will display the message "LOW Input
DC voltage" and beep continuously when the input power to the DCS52
causes the internal voltage level to drop below about 9.5V DC. The
DCS52 is designed to operate with DC input power only with a PS314
power supply.

16.0 Decoder Speed Step Settings

Within the DCC format there are several ways decoders and command stations
communicate speed step information. All of your decoders and command sta-
tion must be "speaking the same version of the DCC language" for everything
to work smoothly. Digitrax DCS52 is set at the factory to send 128 speed step
mode information because the 128 speed step format provides for the best
speed control available. All Digitrax decoders are 128 speed step decoders.
Some older non-Digitrax decoders use other speed step formats and won't
respond to your DCS52 sending 128 speed step information.
If you have a non-Digitrax decoder that can't run in 128 speed step mode,
you can change the number of speed steps the DCS52 sends to that decoder
so that you will be able to control the decoder. This is called Status Editing
the decoder. When you status edit a decoder, the DCS52 will send a different
format to that decoder without affecting the 128 speed step operation of the
Digitrax and other 128 speed step decoders on the layout.
NOTE: Status editing does not reprogram anything in the decoder. It only
changes the messages that are sent to the decoder by the command station.
