03Features
Design and Functions
- Separate monitoring functions address flow, temperature, and sensor wiring.
- The flow relay is energized when flow is present and during the power-on delay.
- The temperature relay is energized when the configured temperature threshold is exceeded.
- The wire-monitoring relay de-energizes for wire break or short circuit.
- Liquid or gas behavior is selected by the documented terminal link.
- Flow and temperature switch points are adjusted by front potentiometers.
- COMBICON connections simplify cabinet wiring and controlled replacement.
Product Identity
Manufacturer: ifm electronic
Model: SN0150
Product Type: VS3000 Control Monitor for Flow Sensors
04Applications
- Cooling-water and lubrication-flow supervision.
- Air and gas flow monitoring with the documented terminal selection.
- Temperature limit and sensor-wire supervision in machine utilities.
- DIN-rail signal evaluation for compatible ifm modular flow sensors.
05Lifecycle & Replacement
- Match SN0150 and the connected ifm sensor before replacement.
- Record both switch points, the power-on delay, liquid or gas selection, and relay wiring.
- Provide the specified fast-acting miniature fuse and adequate cabinet convection.
- After service, verify safe operation, including wire-break and short-circuit behavior.
- Do not replace the monitor with a visually similar unit without checking sensor compatibility and relay logic.
FAQFrequently Asked Questions
