GE IS220YSILS1B Core Safety Protection I/O Pack
The IS220YSILS1B Core Safety Protection (YSIL) I/O pack and associated terminal boards provide an independent backup overspeed protection system. They also provide an independent watchdog function for the primary control (Mark VIeS controller). A protection system consists of three TMR YSIL I/O packs mounted onto a TSCA terminal boards. Three serial cables connect from the TSCA to three SCSAs.
Mark VIeS control is designed with a primary and backup trip system that interacts at the trip terminal board level. Primary protection is provided with the YTUR pack operating a primary trip board (TRPG, TRPA). Backup protection is provided with the YSIL I/O pack operating emergency trip relays (ETRs) on the TRPA.
YSIL accepts 12 speed signals (probes), including basic overspeed, acceleration, deceleration, and hardware implemented overspeed. It monitors the operation of the primary control (Mark VIeS controller) and can monitor the primary speed as a sign of normal operation. YSIL checks the status and operation of TSCA through a comprehensive set of feedback signals. The I/O pack is fully independent of, and unaffected by, the Mark VIeS controller operation.
SIL Capability:
• SIL 2 in HFT = 0 architectures (1 out of 1, 2 out of 2).
• SIL 3 in HFT = 1 architectures (1 out of 2, 2 out of 3).
In the ToolboxST application, when the YSIL variable Speed1 is configured for either Stale Spd En or Speed Dif En (enabled), it must be connected to the controller's speed signal.
For an additional level of protection (LOP), YSIL expects a continuously updated output (ContW dog) from the controller. The variable ContW dog Output must be connected and programmed to be incremented each frame. If the value is not updated within five frames, YSIL generates a trip. This feature allows YSIL to independently verify that the application code continues to run in the controller.
The YSIL I/O pack provides an additional LOP by monitoring the operating health of the system controller.
The following rules apply if this protection is used:
• Simplex main controller with TMR backup protection is supported by the Mark VIeS backup trip board, TSCA. In this configuration, one port on each of three YSIL I/O packs connects to the controller IONet.
• Dual Main Controllers with TMR backup protection is supported by the Mark VIeS backup trip board, TSCA. This configuration uses the dual controller TMR output standard network connection. The first YSIL pack has one network port connected to the R IONet. The second pack has one network port connected to the S IONet. The third pack has one network port connected to the R IONet and one network port connected to the S IONet. The third YSIL monitors the operation of both controllers.
• Triple Main Controllers with TMR backup protection is supported when operating with a TMR main control (2 out of 3). The Mark VIeS backup trip board, TSCA supports this configuration. The network configuration connects the first YPRO pack to the R IONet, the second to the S IONet, and the third to the T IONet.
