❓ Frequently Asked Questions (FAQ)

Q1: What is the purpose of FSC 10302/1/1?
A1: It monitors 5 VDC and 24 VDC power supply lines and generates a watchdog signal to ensure downstream output modules are supplied correctly.

Q2: Can the module be replaced while the system is powered?
A2: Yes, but it may trigger a system central unit reset during replacement, so caution is recommended.

Q3: Is the module suitable for redundant power configurations?
A3: Absolutely. It’s designed to function within both single and redundant power supply systems.

Q4: Where should this module be installed?
A4: In an I/O rack position that connects to the horizontal bus (e.g., slot 1, 2, or 11–18).

Q5: How does it help in system safety?
A5: It prevents undetected power issues by removing the watchdog signal if voltage drops occur, forcing downstream modules to fail-safe mode.

Q6: What happens if both power supplies fail?
A6: The module disables the watchdog output, signaling a fault to the system. This results in a safe shutdown or alarm.

Q7: Does it work with all I/O modules in the FSC system?
A7: Yes, it is compatible with FSC output modules that use watchdog inputs.

Q8: What is the expected lifespan of the module?
A8: Designed for long-term use in industrial systems, typically over 10 years under normal conditions.

Q9: Is software configuration required?
A9: No software setup is needed. It functions based on hardware configuration and placement.

Q10: What is the physical size and weight?
A10: It measures approximately 127 × 25 × 203 mm and weighs 0.2 kg.
