User manual DALLEE ELECTRONICS DIESEL SOUND VERSION 3

[. . . ] IN LOCOMOTIVE DIESEL SOUND for various track power by DCv3 rev8 CAUTION: THIS DEVICE CAN BE DAMAGED BY STATIC DISCHARGE. PLEASE EXERCISE CARE DURING INSTALLATION TO AVOID THIS POSSIBILITY. DISCHARGE YOURSELF TO AN ELECTRICAL GROUND (OUTLET COVER SCREW) BEFORE REMOVING THIS DEVICE FROM ITS ANTI-STATIC BAG. PLEASE READ INSTRUCTION SHEET COMPLETELY BEFORE ATTEMPTING TO INSTALL AND OPERATE THIS PRODUCT. [. . . ] Add a large electrolytic capacitor (470 mfd @ 25 vDC or larger) across this DC supplies output (when power is off). Make sure you observe the polarity markings of the capacitor ! Gray Gray S4 S3 S2 #524 SPDT switch. Switch shown in the OFF position. Drawn as a spst. Red S1 Red Stationary AC power installation using track power for notch setting. speaker You can also add an auxillary Amplifier, see pages 8, 9, and 10. Black Switch key: S1 - Horn (momentary) S2 - Bell S3 - Force Notch 8 S4 - Main sounds off White Red Gray Right Rail Left Rail either rail may be used. Right / Left only used for reference. + ­ ON / OFF switch Red Gray + extra filter capacitor observe polarity ! #524 SPDT switch. Switch shown in the OFF position. Drawn as a spst. fixed AC power 10 - 18 vAC you MUST NOT EXCEED 18 volts AC. DC voltage created from AC is 1. 414 X vAC, 18vAC = 25 vDC !A HUM in the audio output is because the DC power is not filtered enough. Add a large electrolytic capacitor (470 mfd @ 25 vDC or larger) across the DC output as shown (when power is off). Make sure you observe the polarity markings of the capacitor ! Gray Gray S2 Red S4 S3 Red S1 5 DCC receiver installation using motor power for notch settings and function control for HORN, BELL, Full RPM, Main Sounds ON / OFF speaker Black receiver motor leads (Orange / Gray is standard practice). If you are using a seperate receiver merely connect the motor leads to pins 2 (black) and 3 (white) of J3. The sound system presents a load of 480 to 980 ohms (depends on speed set control setting). Make sure that your receiver is operating in the same step mode as the transmitter !! M White Red Gray Connect motor if present DCC track power input Gray No connection is required to J2. All of the sound system power is supplied from the track via J1. Gray S4 S3 S2 S1 Function key: S1 - Horn (momentary) S2 - Bell S3 - Force Notch 8 S4 - Main sounds off Connect S1 thru S4 to function control desired. You do not need to connect functions you do not intend on using. S1 - HORN function. Connect to desired function output of module. Some DCC systems offer a momentary type function. It is best to use what the system you are using suggests. Digitrax - use F2 function Wangro - use F3 function Red Red S2 - BELL function. Suggest function as set by DCC system you are using. Digitrax - use F1 function Wangro - use F2 function S2 -> S4 - function. When using an extra receiver you can use either Forward or Reverse lamp function output of module. Normally not activated = "high". [. . . ] Cut the white wire off or remove from the connector. adding remote volume control when using an Auxillary Amplifier adding manual control to the IN LOCOMOTIVE DC SOUND system as a stationary unit to adjust diesel notches or steam chuff rate. Connect input power, speaker, and all other connections as shown in stationary or other types of installations except no input connections should be applied to the DC motor/track input header (J3) pins 2, or 3. Instead, connections should be done as shown below. All other input power, speaker, switch connections should be done as before. Basic setup for both types of operation: Set NOTCH CONTROL (speed set) full CCW. [. . . ]
