Detailed Description

DUPLEX INTELLIGENT PUMP CONTROL PANEL FOR SEWAGE LIFTING PUMP, WITH THREE PHASE, AC380V/50HZ Model L932-S Eliminates the need for at least 5 water level sensor or 3 float switches: stop-level, normal- level for one pump, high-level for two pumps, overflow-alarm level. Thus significant cost-savings result from dramatically reduced purchasing and clearing of sensors or float switch. More secure because it uses level transmitter, whereas sensors or float switch often fail because of the effect of sludge. Different water levels (depth) for starting or stop the pumps can be set via LCD screen directly and real time depth value displaying; Model L93S-S is specially designed for duplex sewage pumping system, by adopting level transmitter with 0.5-4.5V analog signal, pump user can easily set the different liquid depth for sewage pump operation and observe the dynamic liquid depth in the sump or sewage tank. Typical usage scenarios include: -Chemical, petroleum, pharmaceutical, mining, paper making industry -Cement plant, steel plant, power plant, coal processing industry -Municipal waste water treatment plants -Drainage system -Municipal engineering -Construction site Application & Control characteristic: Connecting 0.5-4.5V level transmitter to replace liquid probe, float switch Pump start and stop according to different depth value setting Duplex pump control Main pump / standby pump automatically alternate Main pump / standby pump automatically switch against malfunction Standby pump participate running if more flow coming Main technical data: Start type: Direct on line (DOL) Qty of controller pump: single pump Rated input voltage : AC380V, Three phase 50HZ/ 60HZ Rated output power : 0. 75kw-4kw (1 hp-5. 5hp) 5. 5kw-11kw (7.5hp-15hp) 15kw (20hp) - - - - Max Motor Output at 380V 3Ph | Relay Max Range(A) | HP | KW | 12A | 1.0 | 0.75 | 1.5 | 1.1 | 2.2 | 1.5 | 3.0 | 2.2 | 5.0 | 3.7 | 5.5 | 4 | 7.5 | 5.5 | 25A | 10.0 | 7.5 | 15.0 | 11 | 20.0 | 15 | 32A | - - - - Product function Over load protection Pump stalled protection Dry run protection with sensor free Under voltage protection Over voltage protection Rapid cycle protection Open phase protection Phase reversal protection Three phase unbalance protection Pump shaft anti-rust protection Product feature Pump start and stop depth value can be easily setting on the LCD screen Pump last five faults record displaying Pump accumulative running time displaying Presenting one dry contact point (BA port) for BMS system Present RS485 port (A+ / B) Remote monitor available (at option) Main installation data Working temperature: -25-- +55 Working humidity: 20%--90%RH, no drips concreted Degree of protection: IP54 Install position: Wall mounting Unit dimension (L x W x H): 302 x 240x 120mm
