1 Applications
The E nergy C ontrol S ystem ( ECS ) allows for unambiguous cost center accounting.
Electrical as well as non-electrical energy and its consumption can be recorded,
optimized and billed to individual cost centers.
The U1601, U1602 and U1603 summators are at the heart of the Energy Control
System (ECS) and enable the recording and billing of both analog and digital quantities.
ECS operating software revision level: V2.57

2 System Description
• Analog signals from orifice plates, measuring transducers or other measuring
instruments are acquired, analyzed and stored together with meter pulses from energy
meters, flow meters and heat meters at the intelligent U1601 summator.
• Each summator can be connected to up to 12 energy meters with pulse output. Data
collected at the meter inputs are integrated and stored according to various criteria to
a semiconductor memory with battery back-up.
• 64 channels are available for the generation of sums and/or differences based upon
meter values. Values from other summators which are connected to the ECS LAN can
be used to generate virtual channels as well. All of the stored measurement values
can be displayed at the summator.
• Stored values can be read out from the U1601 summator with a PC , or can be remote
queried with the help of a modem . A radio-controlled clock for correct time
synchronization or a printer for the generation of reports can be connected to the
second RS232 interface.
• Several summators can be linked to one another via the ECS LAN , a multi-master
compatible RS485 field bus, for applications which required the use of more than 12
inputs (analog/binary). The linking of up to 255 summators from 16xx series
instruments via the ECS LAN allows for the establishment of a powerful energy control
system, which is controlled and monitored with a PC.
• All of the instruments connected to the bus can be queried and programmed from any
desired summator thanks to the multi-master system structure . A limit value violation at
summator M can thus trigger a signal at summator N. Each bus user has access to all
data and functions throughout the entire system.
• LON is a new type of intelligent bus concept with allows controllers, sensors and
actuators to communicate with one another. In addition, up to 63 nodes can be
connected to a U1601 summator via the integrated LON network.
• Two freely programmable relays allow for the generation of messages or the triggering
of specific actions if certain criteria have been fulfilled.
• User generated programs can be installed to the summators through the use of the
system-specific programming language , Energy Control Language (ECL). The
summators can thus be adapted to customer-specific calculations, analyses,
monitoring and optimization independent of the energy control system.
• ECSwin PC software for configuring parameters at the summators, and for reading in
energy consumption data and displaying them in tabular and graphic form.
