Ebsray® pump controllers are an integral and fundamental part of a complete pumping system, ensuring proper pumpset performance and protection against operation outside the specified duty point. Protection is afforded with the "Three-Tier" Protection System, which monitors temperature, pressure and motor current. Optional models are available for total "LPG system" control. Ebsray pump controllers also include protection against dry-running/empty tank, closed or blocked discharge, high LPG temperatures and rapid cycling.
The basic functions of the system are:
- HBT – Operation of the pumpset will be halted if the internal motor temperature exceeds a preset maximum level.
- DPS – Operation of the pumpset will be halted if differential pressure falls below a preset minimum level during operation or is not developed within a preset time after startup.
- MOL – Operation of the pumpset will be halted if motor current exceeds a preset maximum level.
