Features and Functionality

The DP-Levelcontrol is a level-dependent pump control and monitoring unit designed for either one or two pumps.

• General:
  • Compact plastic housing
  • Includes a display
  • DOL (Direct On Line) starting
• Level Detection:
  • Float switch/digital level switch
  • Analog sensor (4...20 mA)
• Operating Principles:
  • Float switch control: Measures level with float switches; pump switches on/off at defined levels; high water alarm activates second pump (if present).
  • Hydrostatic pressure sensor: Measures level and converts to a 4-20 mA signal; pump switches on/off at defined levels; high water alarm activates second pump (if present).
• Programming:
  • Limited parameters available via the Human Machine Interface (HMI) operating panel.
  • Full access to parameters via the service port using a special service port cable.
• Motor Protection:
  • Connects to a thermal circuit breaker (bimetal element) to trip the pump in case of excessive heat build-up. Alerts can be auto-acknowledged or require manual acknowledgement depending on the circuit.
• Control Panel:
  • 7-segment, 5-character display
  • Traffic light LEDs (Red: Alert, Yellow: Warning, Green: Readiness for operation)
  • LEDs for pump operating status (Red: blocked, Flashing yellow: manual mode, Yellow: OFF, Flashing green: running, Green: ready)
  • "High water" LED (red)
  • Navigation keys (Arrow keys, ESC, OK)
  • Manual-0-Automatic switch for each pump (Manual: short period, 0: off, Automatic: controlled by unit)
• Service Interface:
  • Accessible when the control unit is open.
  • Requires an RS 232 cable and "DP-Pumps Service Tool" software (available from DP-Pumps website or Service CD-Rom).
• Measured Value Parameters (Examples):
  • Level (Analog): Fill level in millimetres (if analog sensors are used)
  • Level (Digital): Switching levels if float switches or digital level switches are used
  • Line Voltage: Line voltage in volts
  • Operating Hours Pump 1/2
  • Start Count Pump 1/2
  • Pending Messages: List of acknowledged alerts
• Digital Level Indicator: Provides digital display of current level with associated actions (e.g., Very low: Pump OFF, High: Base load pump ON, High water: High water alert and both pumps ON).
• Additional Connections (J601):
  • Auxiliary voltage for lifting unit: Terminals 18 and 19 (not for present device variant).
  • Signalling output: Terminals 30 and 31 (12.6-13.2 V DC, max. 200 mA) for external alarm equipment.
  • External alarm: Terminals 40 and 41 (e.g., for dry-running protection via NC float switch or sensor). Pumps stop when contact closes (factory setting, configurable via Service Tool). High water alert has priority.
  • Remote acknowledgement: Terminals 50 and 51 to acknowledge alerts remotely.
• Additional Connections (J403): Inputs for thermal circuit breakers for Pump 1 (Alert P1: A03, A01) and Pump 2 (Alert P2: A04, A02). Contacts must be bridged if not available at the pump.
• Enable Input: Terminals 001 and 002. If not bridged, pump control is disabled. Fitted with a wire jumper at the factory. For cables longer than 15 metres, a coupling relay is required.

Parameters and Alerts

The control unit allows setting various parameters and provides alerts/warnings. Parameters displayed depend on the operating mode and measurement method.

• Setting Parameters (Examples):
  • 3-3-2 Stand-by Pump: 0 = dual-pump station with peak-load operation (factory setting), 1 = stand-by pump (one pump ON at high water), 2 = stand-by pump (two pumps ON at high water).
  • 3-3-3 Draining/Filling: 0 = draining (factory setting), 1 = filling.
  • 3-3-4-1 Level Pumps OFF: 250 mm (factory setting) for pneumatic, bubbler, 4-20 mA.

  • 3-3-5-3 Stop Delay: 0 s (factory setting).
  • 3-4-2 Measurement Method: 0 = float switch (with hysteresis; factory setting), 1 = digital level switch (without hysteresis), 2 = 4-20 mA sensor.
  • 3-4-3-1 Level at 4 mA: 200 mm (factory setting).
  • 3-4-3-2 Level at 20 mA: 1000 mm (factory setting).
  • 3-7-1 Check Run ON/OFF: 0 = functional check OFF (factory setting), 1 = functional check performed after idle period of one week.
