T 5724-8 EN Electric Actuators with Process Controller TROVIS 5724-8 (without fail-safe action) · TROVIS 5725-8 (with fail-safe action) For heating and cooling applications Application Electric actuators with integrated PID control modules for simple industrial applications as well as heating, ventilation and air-conditioning systems. For globe and three-way valves, e.g. Types 3222, 3213, 3214, 2488, 42-36 E, 3226 and 3260 as well as Series V2001 in valve sizes DN 15 to 50. The TROVIS 5724-8 and TROVIS 5725-8 Electric Actuators with Process Controllers are a combination of an electric actuator and an integrated digital controller with two PID control modules. The TROVIS 5724-8 Actuator is without fail-safe action and TROVIS 5725-8 with fail-safe action. The TROVIS 5724-8 has a manual override to manually move the valve in de-energized state. Special features •• Universal unit with integrated process controller for –– Flow temperature control based on the outdoor temperature (heating) –– Differential temperature control in district cooling plants •• The TROVIS 5724-8xx and TROVIS 5725-8xx are available in four ready-wired device versions including sensors and control line to facilitate installation •• Fast start-up using configured systems for fixed set point, follow-up, override, cascade or switchover control •• Operating panel with display for set point adjustment and adjustable operating functions, e.g. start/stop control sequence •• Set point range from –50 to +150 °C, adjustment range can be limited •• Maximum power consumption 5 VA (< 44 kWh p.a.), degree of protection IP 54 according to IEC 60529 •• Pump output to control a circulation pump can alternatively be used as a fault alarm output (connected wire L') •• Configuration, parameterization, diagnostic function and direct connection for monitoring using the TROVIS-VIEW software over Bluetooth® Typetested version The TROVIS 5725-8 Electric Actuator with Process Controller is tested in the force-locking version together with various SAMSON valves by the German Technical Inspectorate (TÜV) Fig. 1: TROVIS 5724-8 Electric Actuator with Process Controller according to DIN EN 14597. The registration number is available on request. Note: Details on Types 3222, 3213, 3214, 2488, 42-36 E, 3226 and 3260 as well as Series V2001 Valves can be found in Information Sheet u T 5800 EN and in the associated data sheets. Accessories for communication –– TROVIS-VIEW software The TROVIS-VIEW software can be downloaded free of charge from our website (u www.samson.de at Services > Software > TROVIS-VIEW). The software can also be supplied on a CD-ROM. Further details in Data Sheet u T 6661 EN.
