HydroTOUCH DOL & Soft Start

Enclosure:
- IP56 weatherproof rating
- Powder coated mild steel
- Inner door and removable gland plate
Protection:
- Padlockable mains power isolator switch
- Circuit breaker protected low voltage control and input circuitry
- Individual pump isolation
- Contactor and thermal overload protection of pumps
- Overload protection for strobe
Alarms:
- Visual (strobe) and audible (buzzer) alarms
Control & interface:
- Hydrotouch colour touch screen interface
- Main screen with system, pump, fault and sensor status
- Individual pump monitoring screen with status, run hours and number of starts, auto/off/manual control of pumps
- Graphical overview screen for monitoring system operation
- Alarm screen with date and time stamped faults
- Logged data screen with power and water usage graphs, trend graphs for pressure, level and flow, pump run timers and and system event counters
- System diagnostics screen for easy fault finding, pump rotation testing
- Easy setup commissioning wizard
- Advanced parameter adjustment
Inputs:
- 2x analogue 4-20mA input for transducers
- 3x digital 24Vdc inputs for float/pressure/flow switches
- 1x digital, pulse input for flow meter
- Standard terminal setup: Primary and secondary level transducers, backup low level float and high level float
Outputs:
- 1-12 pump supply outputs
- 5x assignable BMS volt free outputs
- 2x analog 4-20mA BMS outputs for analogue readings
- Modbus RS485 connections

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)
