نظام التحكم في الضغط من Kromschroeder TC2R05W/W (84765631)
The Krom schroder TC 2 84765631 tightness control of two shut-off valves before burner start or after shutdown. Adjustable testing time adapts to various volumes, leaks, and inlet pressures. Suitable for solenoid valves with quick or slow operation, including starting load. Kromschroder TC 2 84765631 tightness control technical data: Weight: 1, 49 kg F1: protection of valve outputs (terminals 15 and 16), fault signal (terminal 12) and supply of the control inputs (terminals 2,7 and 8). F2: protection of the safety interlock/controller enable signal (terminal 6). The input current at terminal 1 must not exceed 5 A. TC switching cycles: 250,000 pursuant to EN 13611. Reset: using a button on the device or by remote reset. Gas type: natural gas, town gas, LPG (gaseous), biogas (max.0.1%-by-vol. H2S) and air. The gas must be clean and dry in all temperature conditions and must not contain condensate. Measurement time tM: 5 to 30 s, adjustable. Set at the factory to 30 s. Medium and ambient temperatures: -20 to +60°C (-4 to +140°F). No condensation permitted. Long-term use in the upper ambient temperature range accelerates the ageing of the elastomer materials and reduces the service life. Storage temperature: -20 to +40°C (-4 to +104°F). installation altitude: 2000 m AMSL. 5 cable glands: M16 x 1.5. Cable cross-section: min. 0.75 mm2 (AWG 19), max.2.5mm2 (AWG14). Valve opening time: 3 s. Housing made of impact-resistant plastic. Connectors: aluminium. Enclosure: IP 65.
