Pump Management Systems Wilo-Control Pump Control Planning Guide Building automation (BA) Automatically controlled processes have become vitally important in advanced building services technology. This particularly applies to all building and mechanical services in the areas of: - Heating systems - Cooling systems - Ventilation systems - Heat pump installations - Combined heat and power plants - Water Supply - Drainage, sewage disposal Automation Management Field Network Network Network Network M Operating station / operating unit Fig.: Building automation – schematic diagram Data interface unit Programming unit Operating unit Communications unit / Controller / ASR Space / Operating unit Data processing apparatus / Server station Application-specific control and regulatory unit M M M Connections within the functional levels Connections between the functional levels Programming unit The BA has the task of controlling the dependencies between the different trades involved in the technical building equipment (TGA). It is in particular the facility management that requires the intersectional exchange of information and data in order to run the building or estates with optimum efficiency and economy. As field devices, pumps are to be seen as components indispensable for operations in the TGA that utilise high power consumption. Operational reliability and economic efficiency of pumps and pump systems are guaranteed to the greatest possible extent by central availability and monitoring of these pumps and pump systems. Due to the rapid technical advances made in the areas of electrical engineering / electronics, potential-free contacts and analogue unit signals are being successively superseded by bus systems.

Pump Management Systems Wilo-Control Pump Control Planning Guide Integration in BA Different communications connections, depending on the kind and extent of a BA system, are required to communicate with signals, commands or data exchange. In Germany, design and functions of BA systems are precisely defined in standard specification VDI 3814. The scope of communication is crucial in determining whether potential-free contacts and analogue signals (2 control cables are required for each kind of information) or intelligent bus systems (all data via a bus line) are used for data transmission. Wilo pumps as well as their optional accessories are equipped with control terminals and respective internal relays enabling communication facilities in line with VDI 3814 requirements. Principle of operation: Mains voltage Control input Signalling relay “Overriding Off” SBM SSM Off 1) 0 0 On On; Pump faulty It is also possible to effect external control functions such as Overriding Off and Overriding Min. by means of customer-provided potential-free contacts, offering the following combinations: • Overriding Off: - Stratos / Stratos-Z / Stratos-D / Stratos-ZD with IF-Moduls -TOP-E/-ED (P 2 350 W) - CronoLine-IL-E / CronoTwin-DL-E - VeroLine-IP-E / VeroTwin-DP-E • Overriding Min.: - Stratos / Stratos-Z / Stratos-D / Stratos-ZD with IF-Moduls • Overriding Off, Overriding Max and Overriding Min: - Stratos / Stratos-Z / Stratos-D / Stratos-ZD with IF-Moduls Stratos PLR and analogue interface converter - TOP-E / -ED with IF-Moduls PLR and Wilo-Control AnaCon - VeroLine-IP-E / VeroTwin-DP-E with Wilo-Control AnaCon - CronoLine-IL-E / CronoTwin-DL-E with IF-Moduls PLR and Wilo- Control AnaCon Wilo Catalogue A2 - Glanded pumps Input NO contact SPDT contact Fault signal in compliance with VDI 3814 closed open closed open Run signal in compliance with VDI 3814 Connection optional Illustration: De-energised idle state (relay not active) 0 = relay inactive SBM = collective run signal 1 = relay active SSM = collective fault signal 1) Mains system voltage “Off” = total breakdown of electronics system 1 0 0 0 0 0 1 1 In addition to these functions the new pumps with communication capabilities feature the option of logging an extensive number of physical actual data. The latest sensor technology records hydraulic and electrical pump data and makes them available via a PLR or LON serial digital interface of the BA. All this information can be exchanged between a pump with communication capability (accessory modules required) and another BA unit via a 2-lead cable. Pumps with communication capability are: • Stratos / Stratos-Z / Stratos-D with IF-Moduls • TOP-E / -ED with IF-Moduls • CronoLine-IL-E / CronoTwin-DL-E with IF-Moduls • VeroLine-IP-E / VeroTwin-DP-E Systems integration The demands made of communication capabilities and functionality are guided through ever more complex hierarchies of building automation as a result of the rising demands made of mechanical services equipment (TGA – also referred to as technical building equipment) in large building projects. This leads to a situation where components at the field level are becoming increasingly technically sophisticated, because – among other things – they also fulfil functional needs at the automation level. In order to lower installation costs and thus investment costs of technical building equipment, and thus also those associated with pump systems, while at the same time increasing their economic efficiency and reliability, it is necessary to use systems with “open communications” and “distributed intelligence”. The Wilo-Control automation and monitoring system offers: • Monitoring and control in accordance with VDI 3814 with - potential-free contacts - analogue signals • Serial digital Interface PLR (Wilo-specific hardware and protocol) of pumps with communication capability is star-connected via a 2-lead cable to a Wilo interface converter or a company-specific coupling module (I / O modules). This connection permits transmission links of up to 200 m. Additional advantages are: - locking protection - immunity to interference - small cross-sections (0.75 mm 2) - shielded cable not required - ECM-protected at both ends - galvanically isolated - interference-voltage-proof up to 250 VAC • Serial bus-compatible Interface RS 485 (standard hardware, Wilospecific protocol) with digital interface converter for communication with digital monitoring units. The data protocol is to be co-ordinated with respective BA manufacturer. • Serial bus-compatible Interface LON with LONTALK protocol and transceiver type FTT10A for connecting electronically controlled LON-compatible Wilo pumps with infrared interfaces to LONWORKS networks. The LONWORKS technology offers installation advantages such as: - locking protection - immunity to interference - small cross-sections (0.75 mm 2 ) - shielded cable not required - ECM-protected at both ends - galvanically isolated - interference-voltage-proof up to 250 VAC - freely selectable topology. 203 Planning Guide Energy-saving pumps Standard pumps Special In-line Pumps Switching and Control Devices Pump Management Systems
