SIS TMR Kernel Power Management
The 5466-1049 module is engineered for triple modular redundancy (TMR) architectures, providing regulated 5 VDC power to the kernel sections of the MicroNet controller. The system utilizes three independent kernel sections (A-B-C), each requiring one dedicated power supply module installed in the primary slot. The module facilitates fail-safe state execution by maintaining power bus integrity, supported by onboard health monitoring. A single front-face LED provides visual status of the 5 VDC and 5 V precharge outputs. This module is exclusively compatible with TMR5200 CPU units; integration with non-compliant CPU architectures will result in system-level faults.
Frequently Asked Questions
Q: Is it permissible to hot-swap a single 5466-1049 module while the TMR controller is active?
A: No. To replace the module, all kernel sections (A, B, and C) must be fully powered down and the modules removed collectively. Hot-swapping individual power modules in an energized state is not supported and may lead to backplane bus instability.
Q: What is the specific role of the fault LED on the front faceplate?
A: The fault LED monitors the operational status of the 5 VDC rail and the 5 V precharge circuit. If the LED indicates an error, it signifies that the regulated output voltage has fallen outside the permissible operating tolerance, necessitating a full system power-down for diagnostic inspection.
Field Installation Guidelines
- Module Placement: Install the 5466-1049 in the first slot of each designated kernel section (A, B, and C). Ensure modules are only installed in compliance with TMR5200 CPU configurations.
- Environmental Constraints: The unit is rated for Class I, Division 2, Groups A, B, C, and D locations. Ensure the cabinet environment is maintained within the 0 deg C to +55 deg C range to prevent derating of the 10 A output capacity.
- Grounding & Shielding: Verify that the chassis backplane ground is connected to the cabinet earth bus to minimize electromagnetic interference, in accordance with CE (EMC) certification requirements.
- Removal Protocol: Prior to installation or removal, ensure all kernels in the MicroNet TMR system are completely powered down to avoid damaging the module connector pins or the backplane interface.
