CronoLine IL-E 50/190-11/2-R1-S1

Glanded centrifugal pump with in-line design for pipe installation with built-in frequency converter for electronic control for constant or variable differential pressure (dp-c/dp-v).

Design:

• Single-stage low-pressure centrifugal pump
• Spiral housing in in-line design (suction and discharge ports with the same flanges in one line), flanges PN 16 – drilled acc. to EN 1092-2
• Pressure measuring connections (R 1/8) for mounted differential pressure sensor (version ...-R1 without differential pressure sensor)
• Pump housing and motor flange with cataphoretic coating as standard.
• Mechanical seal S1 recommended for water-glycol mixtures with glycol proportions up to max. 50% by volume and a fluid temperature of -20 °C up to max. +90 °C to +110 °C and also if the water-glycol mixture contains oil.

Accessories:

• Mounting brackets for fixing to the foundation
• IR-Stick
• IF module PLR
• IF module LON
• IF module Modbus
• IF module BACnet
• IF module CAN
• Control system VR-HVAC
• Control system CCe-HVAC
• Control system SCe-HVAC
• Differential pressure sensor (DDG)

Standard equipment:

• One-button manual operation level for:
  • Pump On/Off
  • Setpoint and speed adjustment
  • Selecting the control mode: Δp-c (constant differential pressure), Δp-v (variable differential pressure), PID controller, n-constant (constant speed)
  • Selection of operating mode in dual-pump operation (main/standby operation, parallel operation)
  • Configuration of operating parameters
  • Fault acknowledgement
• Pump display for indication of:
  • Control mode
  • Setpoint (e.g. differential pressure or speed)
  • Error and warning messages
  • Actual values (e.g. power consumption, actual value of the sensor)
  • Operating data (e.g. operating hours, energy consumption)
  • Status data (e.g. status of SSM and SBM relay)
  • Device data (e.g. pump name)

Additional functions

• 1x “Overriding OFF” control input
• 1x “External pump cycling” (effective only in twin-head pump operation)
• 1x Analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for constant speed (DDC) or remote setpoint adjustment,
• 1x Analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for actual value signal from pressure sensor
• IR interface for wireless communication with Wilo-IR-Stick operating and service device,
• Slot for Wilo IF modules for connection to the building automation system,
• Configurable, potential-free fault and operating/standby signal
• 1x Interface to dual-pump communication
• Three-phase AC motor with frequency converter
• Integrated dual-pump management
• Adjustable time interval for pump cycling (in dual-pump operation)
• Integrated full motor protection
• Different operating modes for heating (HV) or air-conditioning (AC) applications
• Access disable
• Different operation levels: Standard/service
