User manual DALLEE ELECTRONICS STEAM SOUND VERSION 3

[. . . ] IN LOCOMOTIVE STEAM SOUND for various track power by DCv3 rev8 CAUTION: This device can be damaged by static discharge. 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. Save the anti-static bag for possible reuse of storing or shipping the sound unit! OVERVIEW: This device is an electronic, self contained, sound system for installation in model steam locomotives that are designed to operate with conventional DC track power, digital (DCC), other types of command control systems including radio with either track or battery power, or as a stationary sound system. [. . . ] In most cases the 1. 5 ampere (#702) will handle the load. Right Rail pickup CHOKE Battery power - must not exceed 24 volts DC. Use one 9 volt battery or a string of 6 AA or AAA batteries (24 volt DC maximum input). Typical operation of most sound systems for one good 9 volt batteries is about 8 hours, AA or larger is well beyond 50 hours! either rail may be used. looks like coil of wire with a lead on each end Formerly right rail pickup Left Rail Pickup 3 DC track power installation #2 with DALLEE controller #755. With rechargeable or standard battery. speaker When track voltage exceeds battery voltage, the sound system will operate from track voltage instead of battery voltage. Red Black White wires with a " " ARE a connection!wires crossing over (without a " ") DO NOT CONNECT! + ­ Gray Red CHOKE * Gray DC motor lighting circuits Right Rail pickup either rail may be used. Right / Left only used for reference. Left Rail pickup *Larger motors require a larger capacity choke. Optional main sound switch ON / OFF (shown sound "ON") #524 SPDT switch. Switch shown in the OFF position. Drawn as a spst. Chokes: ON / OFF switch Item 702 - 1. 5 ampere loads Item 703 - 5. 0 ampere loads 1N4002 or equivalent diode (item #374) Battery power - must not exceed 24 volts DC. Use one 9 volt battery or a string of 6 AA or AAA batteries (24 volt DC maximum input). Typical operation of most sound systems for one good 9 volt batteries is about 8 hours, AA or larger is well beyond 50 hours! Battery Holders #579 - single 9 volt (shown) #652 - holds 6 AA #654 - holds 2 AA #578 - 9 volt battery snap connector If using a standard battery instead rechargeable, do not connect/use a resistor! of Resistor needs to be calculated for battery type (you must know the charge currents of the batteries used) and maximum track voltage used. R = (Vtrk max - Vbatt nominal) / battery charge current This diagram allows for the use of rechargeable batteries. When track voltage exceeds battery voltage, the sound system will operate from track voltage and the battery will start to charge (when in the forward direction). If you need to charge the battery fully without the sound system on, place the locomotive on the track (with the motor not powered if present) and leave full track voltage on for 14 hours. The batteries will charge whenever the locomotive track power is set for the forward condition regardless of the sound system being on or off. They will not charge when the polarity on the track is set in reverse. When running in reverse, the sound system will only operate from the battery. A bridge rectifier could be used instead of a single diode alleviating this potential problem. ­+ 9V or 6-AA, or 6-AAA batteries For 12 - 14 volt maximum track voltage: 1 - Item #647 (8. 4v / 150mahr) rechargeable battery use 380 ohms (1/4 watt). 6 - Item #648 (1. 2v / 700mahr) rechargeable batteries in series, use 100 ohms (1/2 watt). For 18 volt maximum track voltage: 1 - Item #647 (8. 4v / 150mahr) rechargeable battery use 560 ohms (1/4 watt). 6 - Item #648 (1. 2v / 700mahr) rechargeable batteries in series, use 180 ohms (1 watt). 4 Stationary DC power installation using track power for notch setting. You can also add an auxillary Amplifier, see pages 8, 9, and 10. speaker Black Switch key: S1 - Whistle (momentary) S2 - Bell S3 - Cylinder blow down S4 - Main sounds off White Right Rail Left Rail either rail may be used.

After the cutout sets, mount the speaker Be sure to cover all sides of the cutout to the tender and speaker so no air can escape. If you have other openings, be sure to close them. Optical pattern mounted on drive axle top view of completed speaker installation. Optical Coupler (hi-lighted for ease of viewing) mounted to frame 3/16" from optical end to pattern. In this installation, the end mounting ears had to be trimmed to obtain clearance to the drive gear box. [. . . ]
