FAQ
FAQ
Q1: What is the main function of the 9905‑976 module?
A1: Monitors rotating machinery speed, detects overspeed conditions, and triggers trips to protect equipment.
Q2: Why use three sensors and a 2/3 voting logic?
A2: Enhances system safety; only when two sensors detect overspeed does it trip, reducing false trips.
Q3: What type of speed sensors are supported?
A3: Magnetic pick-ups (MPU).
Q4: What is the trip response time?
A4: Up to 40 milliseconds.
Q5: Does the trip mechanism de-energize the system?
A5: Yes, it cuts power when overspeed is detected.
Q6: Can the module be configured on-site?
A6: Yes, it has a 12-key keypad and display for local configuration.
Q7: What is the operating temperature range?
A7: –25°C to +60°C.
Q8: Is it suitable for critical safety applications?
A8: Yes, it is a high-reliability, redundant protection system for critical rotating equipment.
