Hydrotouch DOL Pump Controller

Function Features

  • Operation:
    • Maximum run timer and auto alternation of pump duty
    • Anti seize timer runs pumps periodically during low use
    • Pump 1 can be configured as a main pump, jacking pump or a mixer
    • Maximum idle time ensures minimum tank level is maintained
    • Staggered pump start and stop
    • Pump limiting
    • Static lead pump for applications with low average flows but high peak flows
    • Supply tank level monitoring (if using level transducer in supply tank instead of backup transducer)
    • Manual override timer control when system is in fault shutdown
  • Fault protection:
    • Pump overload and prime loss shut-down
    • Automatic changeover on pump fault
    • High and low level/pressure shut-down
    • Supply tank low level protection
    • Pump cycle protection
    • Transducer redundancy switches to backup transducer if first one fails (if using secondary tansducer)

Optional Modifications

  • 316 stainless steel enclosure
  • Modbus TCP gateway with ethernet port
  • Netbiter remote access
  • Mains bypass, tank top up or well wash control with solenoid valve
  • UV lamp control
  • Generator input socket and automatic changeover
