Functional Description

DS3800HAIC1B is a Regulator Board developed by GE. It is a part of Mark IV control system. The user interface of the Mark IV Control System is designed for ease of use, with intuitive controls and clear displays. Operators can navigate through various screens to access detailed information on turbine status, performance data, and alarm conditions.

Features

• Modular connectors and retention levers allow it to attach securely to the drive. Retention levers are provided to hold the board firmly in place within the drive, ensuring stable and reliable connections.
• The board is populated with 9 jumpers, which can be configured to alter circuit paths and settings, and 2 trimmer resistor components for fine-tuning electrical resistance within the board. These components are crucial for customizing and optimizing the board’s performance for specific applications.
• A 20-pin connector is included for additional connectivity options, allowing the board to interface with other components within the drive system. Several test points are also present, facilitating troubleshooting and maintenance by providing easy access for signal measurement and diagnostics.
• It is designed to be used within a drive system that incorporates a board rack. The drive features modular connectors at the back of the rack, which the board’s matching modular connector plugs into. These connectors serve two primary functions:
• Power supplies provide the electrical current necessary to power the board.
  Signal transmission enables the board to send and receive signals. These signals include commands sent to other components for processing and incoming signals that the board processes. 

Locking Out an Alarm

Locking out an alarm involves several steps:

• Press the Display Functions switch.
• Select the Alarm Lockout option.
• Enter the drop number of the alarm using the Display Keypad.
• Press Enter.
• This procedure is used to temporarily disable an alarm, preventing it from being displayed or triggered. This is particularly useful during maintenance or when an alarm is known to be faulty and is pending repair.

Unlocking an Alarm

To unlock an alarm, the operator follows these steps:

• Press the Display Functions switch.
• Select the Alarm Unlock option.
• Enter the drop number of the alarm using the Display Keypad. The drop number will appear in inverse video to indicate it is being modified.
