Series description
CronoLine-IL-E

Design

Electronically controlled glanded single pump in in-line design with flange connection and automatic power adjustment

Application

The pumping of heating water (in accordance with VDI 2035), chilled water and water-glycol mixtures without abrasive substances in heating, chilled water and cooling systems.

Equipment/function

Operating modes

  • Δp-c for constant differential pressure
  • Δp-v for variable differential pressure
  • PID-Control
  • Constant speed (n=constant)

Manual operation level

  • Green button and display

Manual functions

  • Differential pressure setpoint setting
  • Setting the speed (manual control mode)
  • Setting the operating mode
  • Setting the pump ON/OFF
  • Configuration of all operating parameters
  • Fault acknowledgement

External control functions

  • "Overriding Off" control input
  • “External pump cycling” control input (only effective in twin-head pump operation)
  • Analogue input 0 – 10 V, 0 – 20 mA for constant speed (DDC) and remote setpoint adjustment
  • Analogue input 2 – 10 V, 4 – 20 mA for constant speed (DDC) and remote setpoint adjustment
  • Analogue input 0 – 10 V for actual value signal from pressure sensor
  • Analogue input 2 – 10 V, 0 – 20 mA, 4 – 20 mA for actual value signal from pressure sensor

Signal and display functions

  • Collective fault signal SSM
  • Collective run signal SBM

Data exchange

  • Infrared interface for wireless data exchange with IR-Stick
  • Plug-in position for Wilo IF-Modules (Modbus, BACnet, CAN, PLR, LON) for connection to building automation

Safety functions

  • Full motor protection with integrated trip electronics
  • Access disable

Dual pump management (twin-head pump or 2 x single pumps)

  • Main/standby operation (automatic fault-actuated switchover)
  • Pump cycling main/standby operation after 24 hours
  • Parallel operation
  • Parallel operation (efficiency-optimised peak-load activation and deactivation)

Technical data

  • Permissible temperature range of -20 °C to +140 °C
  • Mechanical seal for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.
  • Mains connection
    • 3~440 V ±10 %, 50/60 Hz
    • 3~400 V ±10%, 50/60 Hz
    • 3~380 V -5% +10%, 50/60 Hz

Compliance with electromagnetic compatibility without additional measures:

    • Interference emission for residential environment according to EN 61800-3:2018
    • Interference immunity for industrial environments according to EN 61800-3:2018
  • Protection class IP55
  • Nominal diameter DN 40 to DN 200
  • Max. operating pressure 16 bar up to +120 °C, 13 bar up to +140 °C
