Overview
The 20320 Annunciator or Brain is a digital system designed for monitoring and protecting natural gas engines and compressor equipment. The system works by monitoring a variety of inputs and shutting down the engine if an input crosses user-defined shutdown conditions. Additionally, the system monitors, displays, and datalogs the inputs for later user review. The system also contains analog and digital outputs for controlling various processes in the compression system.
All setup and status information is available through the EMIT Interface Module (EIM) or Dynamic Control Touchscreen (DCT) interfaces. The same display can be used for interfacing with other modules, such as the Air Fuel Ratio Controller (AFRC) or ignition. The annunciator can work in tandem with other modules, if present, in various scenarios, or can act as a standalone annunciator.
Key Concepts
Input Types
The following inputs are available on the annunciator:
- Digital Inputs: Can be normally opened or normally closed, and are closed to ground on a faulted or unfaulted condition.
- Analog Inputs: Can be configured to accept 4-20mA, 0-5V and 1-5V sensors. Most commonly used for pressure sensors, though any sensor of the above type can be used.
- Thermocouples: Can be configured to Type K or Type J and monitors temperatures on the system.
- Magnetic Pick Up: Used to monitor the speed of the engine or compressor
Input Class
Each input will belong to a certain input class, which determines if an input is armed. If an input is armed it will fault if it reaches a fault condition. If it is not armed, the input will not fault regardless of the reading. The following are the input classes and their arming condition.
- Class ESD: The input is always armed, even in test mode. For every other input class, the input will not be armed in test mode regardless of class.
- Class A: The input is always armed (Except test mode).
- Class B1: The input will start unarmed after a ‘reset’ button press, and becomes armed after the B1 timer expires.
- Class B2: The input will start unarmed after a ‘reset’ button press, and becomes armed after the B2 timer expires. Generally, the B2 timer is intended to be the shorter B timer.
- Class C: The input will start unarmed after a ‘reset’ button press, and will become armed after it first becomes clear (unfaulted). There is also an optional global C timer to arm all C inputs after a specified time
Alarm Action
Each input will also have an alarm action, which determines what happens when an input is armed and faulted.
- Shutdown: The engine will be shut down. The first input to fault causing the shutdown will be saved for user review.
- Warning: The warning lamp will be illuminated and the state changed to “Running with warnings”
- No Action: Nothing will happen when an input faults. However, the input is still enabled to be viewed in the system.
- Disabled: The input is totally disabled
Additional Alarm Warning
Up to 8 inputs can also have a secondary warning, which will cause an alarm event to be added to the alarm screen when a certain criteria is met. This can be added regardless of the other action of the input (except disabled).
