MultiTrode Safe-TL Backup Controller
View Safe-TL Datasheet >>
The Safe-TL is the next generation of backup control for lift stations and pump stations. Most wastewater utilities around the world install independent high level backup alarms. A small number have installed backup control via PLCs or level relays. With EPA pressure, and budget cuts for staff, more are looking for a comprehensive but cost-effective backup system.
The Safe-TL provides a complete and cost-effective single pump backup solution. Typically a 3-sensor MultiTrode level sensor is connected to the SafeSmart and installed above the primary level - perhaps close to the imminent surcharge point.
In the event of primary level or primary control failure the Safe-TL can take over pump control - allowing the utility more time to deal with the problem. The Safe-TL includes detection of pump thermal problems so avoids the situation of burning out pumps in a backup system.
- Pump control for one pump (either primary or redundant control)
- One level alarm - either high or low
- Manual (hand) operation from an external selector switch or keypad
- Pump thermal protection (thermistor, thermal switch
or Flygt FLS) - Adjustable delays for pump start/stop and alarms
- Failed Probe detection (requires new failsafe probe)
- Adjustable conductivity sensitivity for MultiTrode probe
- Parallel operation with MultiSmart
- Seal and thermal protection from Flygt FLS input
- Remote mount keypad
When used as a backup with an over-ride manual/off/auto switch, the controller will also provide thermal protection in manual mode.
The controller will detect a probe signal failure using the new failsafe MultiTrode probe.
