User manual DALLEE ELECTRONICS DIESEL SOUND VERSION 3 WAUTO HORN

[. . . ] IN LOCOMOTIVE DIESEL SOUND with automated Horn patterns by DCv3 AHrev0 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. [. . . ] 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. SOUND INFORMATION: All sounds are discussed assuming that the sound unit is fully powered at all times. If only powered from track power, the sounds will only start when sufficient track voltage is obtained. PRIME MOVER (DIESEL): sounds range from idle to full RPM with eight notches. With no power to the track / motor the sound system will produce engine idle sounds. As a throttle is advanced to put the locomotive in motion, a brake release will sound (see below) and the diesel will initially accelerate to notch #4, and then seek the correct notch setting for locomotive speed. There will be a distinct volume increase during acceleration. AIR RELEASE (POPS): Air is pumped continuously in a diesel locomotive to maintain pressure in the brake system and for other purposes. Periodically the pressure will increase and the excess will be released through the safety valve. These AIR RELEASE sound (pops) are generated at random intervals during idle and at all notch settings. BRAKE RELEASE: sound is produced when the throttle is advanced from the idle position. This brake release should always precede locomotive movement but will only occur if the diesel sound is actually at idle. This BRAKE RELEASE has been factory preset but is user adjustable. For DC operators, this requires approximatly 1. 5 to 2 volts of input voltage to sense a running mode. 1 HORN: sound is controlled by the reed switch trigger. [. . . ] The battery will be charged with or w/o the switch turned ON. All connections to J1 and J3 are the same as shown above. The external power source can be connected to the engine via a connector so it can be unplugged when operating the engine. Gray Horn Bell + ­ Red ON / OFF switch 1N4002 or equivalent diode (item #374) External power source. resistor same value as selected above. Reed Switch (physical) 9V, or 6-AA, or 6-AAA batteries + ­ The voltage of this external power should equal or be less in voltage than the resistor value selected for the track voltage range used (see upper section). If it is higher, then another resistor needs to be placed in series to lower the charge currents. 4 Auxillary Amplifier connections "Audio input" Connect to gray wire from sound system speaker output. Do not use the red speaker wire from the sound system. [. . . ]
