控制和检测

A detailed analysis of all parameters at the installation site is required to ensure the highest energy saving and the lowest life-cycle costs. Besides weather data, available connecting loads as well as customer-specific data like travel and maintenance periods are included in the concept.

The individual concept of a control system can be integrated in an overall concept with various interlinked components. Both the connection to a visualisation system as well as the integration in existing higher-level control devices and condition-monitoring systems are possible at any time.

Depending on configuration, the following data will be processed in the logic:

Actual power consumption
Energy consumption per day / week / month / year
Status signal of all heating circuits available
Energy storage
Power supply data (power / current / energy)
Error messages
Warning messages to ensure preventive maintenance works
Weather data: wind direction and speed, precipitation type and quantity, air and rail temperature

eltherm systems do more than just trigger heating. They also monitor the complete system and detect errors – if any.

Technical options:

Nominal voltages from 24 V up to 1000 V AC and DC, supply via local network or overhead line
Stand-alone or connection to the control system through glass fibre or copper wires (GSM, GSM-R, Tetra, etc) – mixed operation of different medias possible
Control cabinet systems made of steel, stainless steel, aluminum sheet or glass fiber reinforce plastic (GRP) in protection classes up to IP 68 K
Surge protection systems
Evaluation of weather forecasting services to ensure a timely preheating of facilities

Server Based Control System

The central server offers several benefits:

Central modem pool
All alarms are sent to one place
All alarms are stored in the same database
Alarms can be rerouted into e-mails, SMS messages via server
All software is stored in one place, which means easy maintenance, upgrades and back-up routines
Customised user rights management
