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. 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. [. . . ] 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.

[. . . ] The optical coupler comes with laser printed stripes. In larger tenders with a lot of air passage between the tender top and frame, it may becomes necessary to make your own enclosure as shown here. Especially if you don't want to drill the top open (or it's an oil burner). 11 alternative lighting you might also want to consider installing our Adjustable Regulated Lighting board. The RL-ADJ (item 379) comes with four 2. 7v lamps (item 383) but is capable of driving eight lamps, as shown. You can set the intensity desired (1. 25 - 6. 2 volts). [. . . ]
