Siem ens Variable speed drives SED2 CM1N5192en
Building Technologies 2018-02-28
Use
The SED2 is used for energy-optimized speed control of pump and fan motors in HVAC
applications:
∂ Demand-controlled speed control for supply and exhaust air fans in air handling
systems
∂ Demand-controlled speed control for circulating pumps in HVAC systems
∂ Variable Air Volume (VAV) plants
∂ Cooling tower fans
∂ Condensate pumps
Product documentation
The "Getting started" guide is a short guide in the form of a CD booklet; it contains all
notes and parameters necessary to configure the SED2 based on the factory settings.
The Commissioning Guide contains all information required for mounting, installing and
commissioning the SED2 variable speed drives. It is supplied with the product and also
contains a number of typical SED2 application examples with the relevant information
on the parameter settings.
The Planning Manual is intended for the support of system houses and HVAC planning
engineers when planning and sizing drive systems for HVAC plants.
Without additional control logics, the SED2 support two operating modes. In the comfort
mode, the supply air and extract air fans are controlled exactly according to the actual
demand. Thus, a high level of comfort is guaranteed at lowest energy consumption.
If a fire control panel signals a fire, the SED2 change their operating mode to the fire
emergency mode. This operating mode ensures that rooms for example are specifically
controlled by means of overpressure to make sure escape routes are kept free of
smoke.
This document focuses on interplay between the SED2 and harmonics in the power
supply system.
The document provides practical knowledge, aimed at identifying harmonics at an early
stage and selecting the right approach to solve problems.
