User manual DALLEE ELECTRONICS STEAM SOUND VERSION 3 W AUTO WHISTLE

[. . . ] IN LOCOMOTIVE STEAM SOUND with automated Whistle patterns by DCv3 AWrev8 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. [. . . ] Before proceeding with the installation read the balance of the instructions carefully so you will be completely familiar with what is required and what sounds you should hear. The circuit board should be mounted so that at minimum, the volume control is accessible either through the frame or via a hatch or a hole in the locomotive body shell. Be certain that the components on the circuit board do not come in contact with any metal objects as such contact can destroy the sound system. The speaker should be mounted as per available space bearing in mind that sound reproduction is enhanced when a speaker is properly enclosed and baffled. If a DC locomotive is not moving, there is no track power, therefore to have sound it is necessary to have a separate power supply for the sound system. For in locomotive use, this separate supply is a battery. Without a battery, the sound will not work at lower track voltages. Drawings are supplied for multiple types of connections. If using batteries, we suggest the use of one 9 volt or 6 AA or 6 AAA batteries in series to maximize volume potential and battery life. When connecting the battery (DC) power leads be absolutely certain that wires connect to the proper DC input leads. Installation of the reed switches is easily done by making the appropriate wire connections and placing the reed switch in the proper location for magnet activation. When removing the reed switches, be careful not to crack the glass. Do not bend the leads at the glass ends, use a needle nose pliers to hold the wire entering the glass and then bend the wire. Bending at the glass will break or deform the alignment of the reed switch. Carefully solder wires and cut excess lead ends. Reed switches are not warranted under any circumstance since they are quite fragile and EXHAUST CHUFF is the most notable sound of a steam locomotive in motion. The sound is the result of the used steam from the cylinders being vented through the stack. Each cylinder will exhaust twice during each drive wheel revolution and since most steam locomotives have two cylinders, the exhaust should chuff four times for each drive wheel revolution. EXHAUST CHUFF sounds should vary from a very slow chuff rate to an almost continuous roar at high speed. EXHAUST CHUFF should also vary as to the load on the locomotive with a heavy train making a louder exhaust. This sound system will vary the EXHAUST CHUFF sound either by voltage supplied to the track / motor or, as an option using switch contacts or our OPTICAL INPUT (Item #583), with actual movement of the drive wheels or other axles (see pg 6). When the sound system is initially powered on, voltage variable automatic exhaust chuff is in operation. [. . . ] Switch closure should occur on peaks of quartering lobes. We recommend using optics since they can switch much faster, don't bounce, and do not interfere with the mechanical operation of the axle. Item #707, as shown, is a subminiature micro switch for this purpose, in lieu of using optics (0. 32"L X 0. 1" W X 0. 26" H). Some engines already have switches installed. [. . . ]
