CronoLine IL-E (High Flow, VSD)

In-Line Design

Pumping of heating water (acc. to VDI 2035), cold water and water/glycol mixtures without abrasive substances in heating, cold water and cooling systems.

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

• Energy savings due to integrated electronic power adjustment.
• Optional interfaces for bus communication using plug-in IF-Modules.
• Simple operation with Green Button Technology and display.
• Integrated dual pump management.
• Integrated full motor protection (PTC thermistor sensor) with trip electronics.

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

Single-stage, low-pressure centrifugal pump in in-line design with:

• Mechanical seal
• Flange connection
• Lantern
• Coupling
• Drive with integrated electronic speed control

Materials:

• Pump housing and lantern: EN-GJL-250
• Impeller
• Standard version: EN-GJL-200
• Special version: Bronze CuSn 10
• Shaft: 1.4122
• Mechanical seal: AQEGG; other mechanical seals on request

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 (effective only in dual 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-Monitor/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)
