LED indicators

• DS1 (UON - Yellow): This LED indicator, labeled DS1, is used to indicate the state of the upper power switch or upper power circuit. When the upper power switch or circuit is turned on and actively conducting current, the DS1 LED illuminates, emitting a yellow light. It signifies that the upper power section is in an active state and functioning properly.
• DS3 (UFF - Green): The DS3 LED indicator, labeled DS3, is used to indicate the state of the upper power switch or upper power circuit when it is turned off. When the upper power switch is in the off state or not conducting current, the DS3 LED lights up, emitting a green light. It provides visual confirmation that the upper power section is inactive and not actively supplying power.
• DS2 (LON - Yellow): The DS2 LED indicator, identified as DS2, is used to indicate the state of the lower power switch. When the lower power switch or circuit is turned on and actively conducting current, the DS2 LED illuminates, emitting a yellow light. It signifies that the lower power section is in an active state and functioning properly.
• DS4 (LFF - Green): The DS4 LED indicator, labeled DS4, is used to indicate the state of the lower power switch or lower power circuit when it is turned off. When the lower power switch is in the off state or not conducting current, the DS4 LED lights up, emitting a green light. It provides visual confirmation that the lower power section is inactive and not actively supplying power.

Gate Driver Power Supply

• P15L: Represents the positive power supply voltage for the lower gate driver. It provides a +15 V direct current (dc) power to the lower gate driver circuit. This voltage level is crucial for enabling the proper operation of the lower gate driver and facilitating the control signals needed to drive the lower power devices effectively.
• N7L: Refers to the negative power supply voltage for the lower gate driver. It supplies a -7.5 V dc power to the lower gate driver circuit. This negative voltage is necessary to establish the appropriate biasing and voltage levels required for reliable and efficient gate control of the lower power devices. It ensures the proper functioning of the lower gate driver.
• P15U: Signifies the positive power supply voltage for the upper gate driver. It delivers a +15 V dc power to the upper gate driver circuit. Similar to the P15L, this voltage level is vital for facilitating the control signals and gate driving requirements of the upper power devices, ensuring their optimal performance and operation.
• N7U: Denotes the negative power supply voltage for the upper gate driver. It supplies a -7.5 V dc power to the upper gate driver circuit. This negative voltage plays a critical role in establishing the necessary biasing and voltage levels for effective gate control of the upper power devices. It enables reliable and efficient operation of the upper gate driver.

Third-Party Connectivity

GSM supports turbine control commands, data and alarms, alarm silence, logical events, and contact input sequence of events records with a resolution of 1 ms. One of three methods can be used to connect the system to the plant's DCS:

• Modbus link from the RS-232C port of the HMI Server to the DCS
• A high-speed Ethernet link at 10 Mbaud using the Modbus over TCP/IP protocol
• A high-speed Ethernet link at 10 Mbaud using the TCP/IP protocol and an application layer known as GEDS Standard Messages (GSM)

Fault Detection

• A system with redundancy may be less reliable than a system without redundancy. The system must be capable of detecting and reporting faults so that they can be repaired before a forced outage occurs.
• Fault detection is required to ensure that a component or group of components is functioning properly. One or more of the following methods are used to detect faults.
• Process operator inspection;
• Equipment operator inspection.
• Special hardware circuits for operation monitoring
• Hardware and software watchdogs
• Logic in software
• Heartbeats in software There are numerous potential failure points in complex control systems. To create foolproof fault detection, this can be very expensive and time consuming.
• The failure to control a system's outputs is the most dangerous. To achieve the highest level of reliability, fault detection must be determined as close to the output as possible. The Mark VIe provides a high level of detection and fault masking by voting the outputs of all three controllers and monitoring discrepancies using triple redundant controllers and I/O modules.

Output Processing

The three controllers' signal outputs are divided into three categories:

• Outputs are driven from individual I/O networks as single ended non-redundant outputs;
• Outputs exist on all three I/O networks and are merged into a single signal by the output hardware.
• Outputs exist on all three I/O networks and are output separately to the controlled process. This procedure may include external voting hardware.

The three signals feed a voting relay driver, which operates a single relay per signal for normal relay outputs. For critical protective signals, the three signals feed a voting relay driver, which operates a single relay per signal. Three independent relays are driven by the three signals, with the relay contacts connected in the standard six-contact voting configuration.
