DP-Level control

Summary

Product identification

The DP-Levelcontrol is a pump control and monitoring unit housed in a compact plastic casing, designed for either one or two pumps.

• Thermal circuit breaker connections (J403):
  • Terminal 121 and 120: Thermal circuit breaker first pump (NC) - causes alarm A03
  • Terminal 122 and 121: Thermal circuit breaker first pump (NC) - causes alarm A01
  • Terminal 221 and 220: Thermal circuit breaker second pump (NC) - causes alarm A04
  • Terminal 222 and 221: Thermal circuit breaker second pump (NC) - causes alarm A02
• Enable input: Terminals 001 and 002 (factory fitted with a wire jumper; if not bridged, pump control is disabled. For cables longer than 15 meters, a coupling relay must be fitted).

Control and Operation

The control unit is a level-dependent pump control and monitoring unit. It supports tank draining applications using various level detection methods:

• Float switch control: Pumps activate when the "float switch on" level is reached and empty the reservoir to the "float switch off" level. A high water alarm activates and a second pump starts (if present) upon reaching the high water level.
• Hydrostatic pressure sensor: Measures level and converts it to a 4-20 mA signal. Similar to float switch control, pumps activate and deactivate based on defined levels, with a high water alarm and second pump activation (if present) at high water.

The DP-Levelcontrol can be programmed via its Human Machine Interface (HMI) operating panel for limited parameters, or via a service port for full access using the "DP-Pumps Service Tool" software.

Control Panel Features:

• Display: 7-segment, 5-character display.
• Traffic light LEDs:
  • Red: Alert (one or more alerts)
  • Yellow: Warning (one or more warnings)
  • Green: Readiness for operation
• LED for pump operating status (per pump):
  • Red: Pump blocked by alert or no enable signal
  • Flashing yellow: Pump running in manual mode
  • Yellow: Pump OFF
  • Flashing green: Pump running
  • Green: Pump ready for operation
• "High water" LED: Red, lights up if a high water alert is output.
• Navigation keys: Arrow keys (up/down), ESC (cancel/move up menu), OK (confirm/move next digit).
• Manual-0-Automatic switch: Allows manual operation, pump off, or automatic control by the unit.

Measured Value Parameters (examples):

• 1-1-1 Level (Analog): Fill level in millimeters (if analog sensors are used).
• 1-1-2 Level (Digital): Switching levels if float switches or digital level switches are used.
• 1-1-3 Line Voltage: Line voltage in volts.
• 1-2-1 Operating Hours Pump 1.
• 1-2-2 Start Count Pump 1.
• 1-3-1 Operating Hours Pump 2 (for dual-pump stations).
• 1-3-2 Start Count Pump 2 (for dual-pump stations).
• 2-1-1 Pending Messages: List of acknowledged alerts.

Digital Level Indicator:

• Very low: Pump OFF
• Medium: Before base load pump is started
• High: Base load pump ON
• Very high: Peak load pump ON
• High water: High water alert and both pumps ON

Parameters (examples):

• 3-3-2 Stand-by Pump: Configures dual-pump (0), stand-by (1 pump HW) (1), or stand-by (2 pumps HW) (2) operation.
• 3-3-3 Draining/Filling: Sets operation mode to draining (0) or filling (1).
• 3-3-4-1 Level Pumps OFF: Stop level of pumps in millimeters (e.g., 250 mm).
• 3-3-4-2 Level Base Load ON: Start level of base load pump in millimeters (e.g., 400 mm).

• 3-3-4-4 Level High Water: Level for high water alert in millimeters (e.g., 600 mm).
• 3-3-5-3 Stop Delay: Stop delay of base load pump in seconds (factory setting: 0 s).
• 3-4-2 Measurement Method: Selects float switch (0), digital level switch (1), or 4..20 mA sensor (2).
• 3-4-3-1 Level at 4 mA: Measured value at 4 mA in millimeters (e.g., 200 mm).
• 3-4-3-2 Level at 20 mA: Measured value at 20 mA in millimeters (e.g., 1000 mm).
