Page 7: General Information
Congratulations on purchasing one of the finest HF amplifiers in the world today. ACOM is pleased that you have chosen one of our products, and we will endeavor to provide you with the information and support you need to enjoy your purchase for many years. -
Page 8: Features
Easy maintenance. Signatures of the amplifier internal status are stored in a nonvolatile memory for 7 most recent auto protection trips. This information can be forwarded to your dealer for diagnostics. Using an EXCEL APPLICATION (available from ACOM or your dealer free of charge) and a PC you can decode the signatures by yourself, too. -
Page 9: Safety Considerations, Explicit Definitions
1.5. Safety Considerations, Explicit Definitions The ACOM 1000 HF + 6 meters Linear Amplifier is a Safety Class I unit. The third grounding lead of its mains cord (which is colored yellow with two green stripes) and the ground stud on the rear panel of the amplifier (marked GND) must be connected to the station's grounding system for safe operation. - Page 10 User's Manual | ACOM 1000 | HF + 6m Linear Amplifier PRECAUTIONS: D A N G E R ! H I G H V O L T A G E ! The amplifier works with high voltages up to 3000V, which are LETHAL! For your safety, pull the amplifier power plug out of the mains wall outlet and WAIT AT LEAST 30 minutes EACH TIME BEFORE you remove the cover of the amplifier.

Page 11: Installation
N O T E Before you install your amplifier, thoroughly read this manual. First, carefully inspect the cardboard carton and its contents for physical damage. ACOM ships amplifiers in highly protected containers, but it cannot assure that mistreatment by shippers will not occur. -
Page 12: Amplifier Location Selection
User's Manual | ACOM 1000 | HF + 6m Linear Amplifier 2.3. Amplifier Location Selection N O T E The weight of the unit is about 22kg, which should preferably be handled by two persons. Position the amplifier near the place where it will be used. You will need an easy access to the command knobs and indicator's area, as well as to the rear panel cabling. -
Page 13: Figure 2-1 Connections
User's Manual | ACOM 1000 | HF + 6m Linear Amplifier Figure 2-1 Connections First, connect the ground stud of the amplifier (on the rear panel, marked GND) to the station’s grounding system (see Figure 2-1 Connections Connect a coaxial cable with a PL-259 plug from the transceiver output to the amplifier rear panel RF INPUT socket. - Page 14 User's Manual | ACOM 1000 | HF + 6m Linear Amplifier N O T E Your amplifier will not work if KEY-IN is not connected properly. Transceiver producers give different names to this output and they are for instance TX- GND, SEND, T/R-LINE, etc.

Page 15: Installation Of External Fan
User's Manual | ACOM 1000 | HF + 6m Linear Amplifier It is preferable that you use the wall outlet closest to the source. The installation leads should be at least 1.5mm² (AWG 15 or SWG 17). Check if the respective fuses can handle current up to 10A as well, and whether the voltage corresponds to the voltage for which the amplifier is set (see Section 2.2 Line Voltage... -

The control of the amplifier is accessible during OFF LINE and ON LINE states, each having several... -
Page 18: Operation
User's Manual | ACOM 1000 | HF + 6m Linear Amplifier 4. OPERATION Operation of the amplifier is simplified due to the TRI tuning aid, Auto-Operate function, and automatic protection system, so you'll be able to begin using the amplifier immediately after the installation. -
Page 19: Changing Operate And Standby Modes
User's Manual | ACOM 1000 | HF + 6m Linear Amplifier After the indicated period expires, the ON/OFF button stops flashing and lights green constantly. If the auto-operate function is selected to ON (see Section ), the green 5.2 Auto-Operate enabling and disabling OPER LED lights too. - Page 20 User's Manual | ACOM 1000 | HF + 6m Linear Amplifier The amplifier can operate safely as long as the REFLECTED POWER is LESS THAN 300W. Also, impedance matching is assured for loads presenting a VSWR of up to 3:1. Although for some loads and bands, matching is possible at even higher VSWR levels, the drive power must be reduced to prevent the REFLECTED POWER from exceeding 300W.

User's Manual | ACOM 1000 | HF + 6m Linear Amplifier Tuning to the left of the center would lead to the opposite: less gain and more power attainable. Of course, this requires more drive power, more plate current, and more plate heat, which shortens tube's-expected life, as its cathode would be faster exhausted. -
Page 24: Auto-Protection System
User's Manual | ACOM 1000 | HF + 6m Linear Amplifier 4.5. Auto-Protection System When any abnormal condition is detected, the amplifier will evaluate the risk and may use three different degrees of protection, depending on the nature of the problem. Each event is accompanied by a text telling you the reason. -
Page 25: Off Line Operation
User's Manual | ACOM 1000 | HF + 6m Linear Amplifier 5. OFF LINE OPERATION There is a control function and 14 information screens available in this state of the amplifier. You can enable/disable the Auto-Operate feature. You can also list the auto - protection signatures. The tube is not powered at all (only the micro-controller is active) during these operations. -
Page 26: Reading Auto-Protection Signatures
User's Manual | ACOM 1000 | HF + 6m Linear Amplifier 5.3. Reading Auto-protection Signatures On every Hard Fault protection trip of the amplifier, signature information is stored in its nonvolatile memory. The 7 most recent auto-protection trip signatures related to the amplifier internal status are stored there, which you can copy and forward to your dealer for diagnostics. -
