Electronic control unit for level control of one (AD) or two (BD) d.o.l. starting submersible pump(s).
The BasicLogo with the standard features meets all the necessary requirements for the reliable control of sewage pumps. It can be adapted to individual requirements and is suitable for use with both non explosion protected and explosion protected submersible pumps (AD/BD ...Ex types).
The control unit can be combined with a large variety of different level controls to suit the application concerned, and it is supplied with a buzzer as standard with a facility for off the line operation.
All AD/BD ...ExM control units have a run dry protection (DRP) and an integrated static air level control with two independently operating pressure switches, which ensure high operating safety and low maintenance and therefore lower costs. In addition, the control units have a facility to adjust the pump follow-up time and start-up delay after a power failure, thereby optimising the pressure drainage system.
All BD types (for two pumps) automatically start up pumps 1 and 2 alternately. The resting pump is switched on during peak load or fault. Alternative operation of the unit without peak load function is possible, but with automatic switchover to the standby pump in the event of a fault. Variegated automatic start delay time after a power failure to prevent extreme rushes of current.
