2 Installation Caution! Versions designed to handle temperatures up to 200 °C must be fitted with the dark gray graphite supplied with the valve. Do not use the UDP seals available as accesso - ries as they are only suitable for tempera - tures up to 150 °C.
3 Attaching the actuator to the valve If the actuator has not already been mounted on the valve by the manufacturer or when the original actuator on a valve is to be replaced with a controller with electric actuator, proceed as follows.
4 Electrical connections Upon installing the electrical cables, you are required to observe the regula - tions concerning electrical power in - stallations according to DIN VDE 0100 as well as the regulations of your local power supplier.
The default setting (WE) is configured for an application with a Pt 1000 flow temperature sensor and water flowmeter (see Fig. 3). 4.3 Type 5724/5725 Controller with Electric Actuator Domestic hot wat.
5 Manual override The direction of action and travel can be read off the travel indication scale. 5.1 Type 5757/-7 Controller with Electric Actuator Caution! Only activate the handwheel when the actu - ator is disconnected from the power supply.
6 Operation The controllers with electric actuators are adapted to the required control task by configuration and parameterization per - formed in TROVIS-VIEW Operator Interface: 4 Type 5757-7 : TROVI.
7 Maintenance The control valve is subject to natural wear. Depending on the conditions the valve is op - erated in, it needs to be checked at regular intervals. If leakage to the atmosphere occurs, remove the valve from the pipeline and replace the damaged parts.
