Installation / Setup

The installation/setup highlights for the MODEL FR“<A4C RECEIVER include the following:

– Unpacking: Carefully remove the receiver from its packaging and inspect for any damage. Retain the packaging for potential future use or inspection by the transport company.
– Placement: Ensure the receiver is well-ventilated and avoid excessively hot locations. Maintain at least one inch of clearance around the device and avoid covering it with books or papers.
– Mounting Options: The receiver can be positioned in various ways using the supplied mounts and rubber feet. Instructions are provided for changing the position by removing and reattaching parts.
– Power Requirements: The receiver is factory-set for 120 Volts 50/60 Hz AC but can be switched to 240 Volts AC. Adjust the switch on the back of the unit accordingly and secure it to prevent accidental changes.
– Grounding: Connect the ground terminal on the back of the receiver to the station’s ground. If used with other equipment, connect a grounding strip between all devices.
– Antenna Connection: The antenna input labeled “ANT” has a nominal impedance of 52 Ohms.
– Mute Function: The “MUTE” jack allows for an external standby switch connection. The receiver is shipped with a crossed plug in the jack, which should be removed if used with a transmitter.
– Audio Output: The “ANTIVOX” jack provides a high-impedance audio output for use with a transmitter’s anti-vox circuit.

Manual Overview

The Drake ESPAGNOL PS-7 Model 1502 is a regulated power supply providing 13.6 volts and up to 25 amperes of continuous current. It features a silicon monolithic integrated circuit for excellent voltage regulation and includes short-circuit and overvoltage protection. For troubleshooting, the unit automatically shuts off during overload or short-circuit conditions, and can be reset by toggling the power switch or removing the AC input. Overvoltage protection engages if output exceeds 16 VDC, grounding the output and blowing the primary fuse. Calibration and adjustments involve internal controls preset to 13.6 volts and 25 amperes. For line voltage programming, the unit is factory-set for 120 VAC but can be adjusted to 100, 200, or 240 VAC by repositioning internal switches and replacing the fuse accordingly. The auxiliary DC output is protected by an internal 1-amp fuse. For continuous high-demand operations, such as RTTY or SSTV, the optional FA-7 cooling fan is recommended, especially in environments exceeding 25°C. Repair services are available from the manufacturer, provided there is no external tampering.

Quick Issues Covered

• Diagnose power-up failures with voltage programming adjustments.
• Identify and replace fuses for overload protection.
• Trace circuits using provided schematics for fault isolation.

Installation / Setup

Ensure adequate space around the PS-7 for proper air circulation, especially near heat sources. Avoid placing objects on top of the unit to prevent overheating. The PS-7 is preset to operate at 120 VAC 50-60 Hz, but can be adjusted to other voltages by removing the programming plate and adjusting the voltage switches. For continuous heavy-duty operations, such as RTTY or SSTV, it is recommended to install the model 1529 FA-7 cooling fan if ambient temperatures exceed 25°C.

Safety & Warnings

Se debe tener especial atención para asegurar la provisión de un espacio adecuado alrededor de la PS-7 para la circulación apropiada de aire, especialmente cerca de fuentes de calor. Evite colocar libros, papeles u otros accesorios del equipo en la parte superior de la unidad para prevenir el sobrecalentamiento. En caso de sobrecarga o cortocircuito, el circuito regulador se apagará automáticamente y la unidad puede reiniciarse cambiando momentáneamente el interruptor ON-OFF a OFF o eliminando la tensión primaria de CA. El transformador de potencia está protegido por un fusible que debe ser reemplazado por otro del mismo tipo y rango si es necesario. Si la sección del regulador falla o uno de los transistores de paso entra en cortocircuito, la unidad se apagará automáticamente y un tiristor colocará la salida a tierra para proteger la carga, abriendo el fusible primario que debe ser sustituido después de corregir la causa de la sobrecarga.
