Functional Description
DS200SVAAG1A is a Voltage Attenuator Board designed and developed by GE. It is a part of General Electric Drive control system. A voltage attenuator board is a circuit board designed to attenuate or reduce the amplitude of an input voltage signal to a desired level. Attenuation refers to the process of reducing the strength of a signal without significantly affecting its waveform. In the context of electronic circuits, an attenuator is a device that can reduce the amplitude of a signal while maintaining its integrity.
The voltage attenuator board typically contains one or more resistive voltage divider circuits, which use a combination of fixed resistors to divide the input voltage by a specific ratio. By selecting appropriate resistor values, the board can provide a specific level of attenuation that meets the requirements of a particular application. The attenuated signal can then be output to other circuits or devices. Voltage attenuator boards are commonly used in audio and video applications, as well as in measurement and testing equipment. They can be used to reduce the level of a high-amplitude audio or video signal to prevent distortion or to provide a more appropriate level for further processing. In testing applications, voltage attenuator boards can be used to reduce the voltage of a signal to a safe level for testing or analysis without damaging the test equipment.
Features
- It has multiple test points and eight cable attachment terminals. The terminals on the board are given numbers that begin with the letter SC. The first three terminals, for example, are designated as SC1, SC2, and SC3.
- If you suspect that the board isn't working or is having intermittent problems, the test points on the board can help. Only a qualified servicer with qualified testing equipment can use the test points. If you suspect a problem, however, it is best to first use the diagnostic tools available on the drive. The diagnostic tool will generate a report detailing the components and their performance. It can be used to identify problems or areas that can be improved.
- The drive features a control panel with a two-line display as well as a keyboard for selecting options and scrolling through menu options. There are two types of menu options.
- Most are used to gain access to configuration areas for editing and viewing. The configuration defines the parameters that govern how the drive operates and can be changed via the control panel. Other menu options allow you to run the diagnostic tools. After the tool generates a report, you can save it to your laptop or other device. You can save the file for later use, which may be useful for comparing diagnostic results after a repair is completed.
Product Attributes
- It is designed for use in GE turbine control systems. The board is responsible for attenuating the voltage of the signal received by the turbine control system from various sensors, such as temperature sensors, pressure sensors, and speed sensors. The attenuated voltage signal is then sent to the control system for processing.
- The board consists of several key components, including resistors, capacitors, and amplifiers. These components work together to attenuate the incoming voltage signal to the appropriate level for processing by the control system.
- The board is designed to be easily installed into the GE turbine control system and is compatible with a variety of different sensors. It is also designed to be durable and reliable, with a long lifespan and minimal maintenance requirements.
IDOS OS
- IDOS schedules the I's microprocessor tasks to support the turbine's and driven device's operation, control, and protection. IDOS is a priority-based, interrupt-driven, preemptive scheduling system.
- Tasks are assigned a priority code ranging from 0 to 15, with 0 being the lowest and 15 being the highest. Because it is interrupt-driven and preemptive, an interrupt with a higher priority code takes precedence over other tasks that are running at the time the interrupt is received. The priority code for MS-DOS, which runs under IDOS on the I, is 4. GEDS handles optimal priority scheduling, which cannot be changed by the user. IDOS is the top-level operating system when it is invoked during startup (via the AUTOEXEC.BAT file).
- Its primary function is to allow real-time communication with the control panel(s), particularly for alarm annunciation. When loading and running other DOS-based programs on the I, several precautions should be taken. RAM disks are not recommended because the amount of extended memory available on a typical factory-configured I is insufficient to support RAM disks. Expanded or extended memory managers do not improve I operation and are not recommended.
Backup Interface
- On the cabinet door is a small backup interface. It displays key control parameters and alarms on a liquid crystal display with two lines of 40 characters each. It can also be used to issue operator commands. An RS422 connection can be used to provide a second backup interface for remote mounting. The door has an emergency stop pushbutton. It has a latching contact that must be turned and pulled in order to be reset.
- For remote mounting, loose emergency stop pushbuttons can be provided. The trip solenoids are hardwired in series with all emergency stop pushbuttons. Diagnostics monitor the trip circuitry and cause a separate trip to be initiated in the application software.
Replacing Software
- Remove one of the old card's two EPROM chips (U6 or U7) and insert it into the appropriate socket on the new SLCC. When removing and inserting EPROMs, use the proper extraction/insertion tool to avoid component damage. To avoid memory chip damage, make sure the chips are properly oriented when inserting them into sockets.
- Repeat steps 1 and 2 for the remaining EPROMs.
- Install new EPROMs if the failure symptoms that caused the card to be replaced persist.
