VMF-RLC16-V111 Relay Controller | Critical Steps
Function: Provides 16 configurable safety relays (NO/NC/form C) for trip/alert signaling in VM600 protection systems.
200-570-101-015: Standard unit200-570-000-111: Redundant pair configuration
Commissioning Sequence
-
Safety Pre-Checks
- Verify SIL2/PLe certification labels match application requirements.
- Disconnect upstream power before wiring (arc flash risk).
-
Hardware Installation
- Power Input: 24V DC ±10% to
PS1/PS2(redundant) terminals. - Relay Wiring:
- Terminate load cables to screw terminals (max 5A @ 250V AC / 30V DC per channel)
- Connect chassis ground to dedicated lug (≤0.1Ω resistance)
- Power Input: 24V DC ±10% to
-
Configuration
- Set relay logic via VM600 ConfigTool:
- Navigate:
Hardware→RLC16→Trip Logic - Assign triggers (e.g., Channel 1 = Turbine overspeed)
- Navigate:
- Redundant Models (
000-111only):- Link primary/secondary modules via fiber-optic sync cable (ST connectors)
- Enable
Cross-validationin software
- Set relay logic via VM600 ConfigTool:
-
Relay Validation Testing
- Force trip signals from VM600 software.
- Measure relay response time: ≤8ms (activate-to-contact closure).
- Verify contact resistance: ≤100mΩ with 10A load.
Operational Monitoring
| LED Status | Indication | Action |
|---|---|---|
| Green (PWR) | Power OK | Normal operation |
| Red (FLT) | Internal fault | Check event log (VM600 software) |
| Amber (SYNC) | Redundancy sync active (000-111) |
Validate heartbeat signal |
| Channel LEDs | Red = Tripped, Green = Ready | Verify trip source |
Critical Requirements
| Aspect | Specification |
|---|---|
| Environmental | -40°C to +85°C (derate >60°C) |
| Electrical Clearance | ≥150mm from >600V conductors |
| Relay Life | 100,000 cycles (resistive load) |
| Firmware Updates | Use Vibro-Meter ServiceTool + SD card (FAT32) |
Troubleshooting
| Issue | Resolution |
|---|---|
| Relay fails to trigger | 1. Check trip logic assignments 2. Test coil voltage (min. 18V DC) |
| Redundancy sync loss | 1. Inspect fiber-optic cable 2. Verify identical firmware versions |
| Contact welding | Replace relay cartridge (P/N 200-575-003-010) |
