TROVIS 5757-3 Electric Actuator with Process Controller - 1

TROVIS 5757-3 Electric Actuator with Process Controller for domestic hot water heating Application Electric actuator with integrated digital controller used to position force-locking valves in nominal sizes DN 15 to 25. Domestic hot water heating control in instantaneous heating systems used in small to medium-sized buildings connected to a district heating or local heat supply network. The TROVIS 5757-3 is a combination of an electric actuator and an integrated digital controller. It is especially designed for DHW heating in instantaneous heating systems for small to medium-sized buildings. It is particularly suitable for mounting to SAMSON Types 3222, 3222 N, 2488 and 3267 Valves as well as to special versions of Type 3226 and Type 3260 Valves. Special features •• Control using two different set points, e.g. DHW temperature and DHW temperature for thermal disinfection. A binary input is used to switch between the set points. •• Function to maintain water temperature constant, preventing the heat exchanger from cooling down between tapping •• Direction of action reversible –– Globe valve opens when the actuator stem retracts (increasing/increasing) –– Three-way mixing valve mixes/diverts the flow(s) when the actuator stem extends (increasing/decreasing) Fig. 1: TROVIS 5757-3 Electric Actuator with Process Controller •• Limit value monitoring: –– The valve is closed by the actuator when the maximum adjustable limit is exceeded –– The frost protection function is started when the temperature falls below the minimum adjustable limit •• Configuration, parameterization, diagnostic function and direct connection for monitoring using the TROVIS-VIEW software –– Direct data transmission using a connecting cable (direct connection to computer) –– Data transmission over a memory pen •• Maintenance-free •• Special valve version available for small tapping amounts Accessories –– TROVIS-VIEW configuration software for TROVIS 5757-3 Electric Actuator with Process Controller –– Hardware package with a memory pen-64, a connecting cable and a modular adapter (order no. 1400-9998) –– Memory pen-64 (order no. 1400-9753) –– Type 5207-0060 Pt 1000 Sensor –– Sensor pocket (order no. 1400-9249) –– Water flow sensor with extension cable with mating connector (order no. 1400-9246) Note: Details on Type 3222, Type 3222 N, Type 3267, Type 3226 and Type 3260 Valves can be found in the Data Sheets u T 5866

TROVIS 5757-3 Electric Actuator with Process Controller - 2

Electrical equipment The actuator consists of a digital controller which is integrated into the electric actuator housing. The actuator requires a Pt 1000 temperature sensor (e.g. Type 5207-0060) to be connected for it to function. The fast-response Pt 1000 sensor allows the temperature to be controlled to the corresponding set point almost immediately. Two set points W1 and W2 can be used. A binary input is used to switch between the set points. The digital controller is connected to a temperature sensor on the input side which can be optionally upgraded by a water flow sensor or a flow...
