LV24A-MP-REGlobe Valve Actuator, AC/DC 24 V

• 500 N, 15 mm
• AC/DC 24 V, modulating, MP-Bus
• Operating range DC 2...10 V
• Position feedback DC 2...10 V
• Actuating time motor 150 s / 15 mm
• IP 54, Manual override with push-button, can be locked

Mode of operation: Conventional operation: The actuator is connected with a standard modulating signal of DC 0 ... 10V and drives to the position defined by the positioning signal. The measuring voltage U serves for the electrical display of the actuator position 0 ... 100% and as slave control signal for other actuators.

Operation on the MP-Bus:

The actuator receives its digital positioning signal from the higher level controller via the MP-Bus and travels to the position defined. Connection U serves as communication interface and does not supply an analogue measuring voltage.

Converter for sensors: Connection option for a sensor (passive or active sensor or switching contact). The MP actuator serves as an analogue/digital converter for the transmission of the sensor signal via MP-Bus to the higher level system.

Parameterisable actuators: The factory settings cover the most common applications. Input and output signals and other parameters can be altered with the PC-Tool MFT-P or with the Service tool ZTH EU.

Installation on third-party valves: The retrofit actuators for installation on a wide range of valves from various manufacturers are comprised of an actuator, bracket, universal valve neck adapter and universal valve stem adapter. Adapt the valve neck and valve stem to begin with, then attach the retrofit bracket to the valve neck adapter. Now fit the retrofit actuator into the bracket and connect it to the valve. Whilst taking the position of the valve closing point into account, secure the actuator to the bracket and then conduct the commissioning process. The valve neck adapter/actuator can be rotated through 360° on the valve neck, provided it is permitted by the size of the installed valve.

Installation on Belimo valves: Use standard actuators from Belimo for mounting on Belimo globe valves. The installation of retrofit actuators on Belimo globe valves is technically possible.

Manual override: Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked). The stroke can be adjusted by using a hexagon socket screw key (4 mm), which is inserted into the top of the actuator. The stroke spindle extends when the key is rotated clockwise.

High functional reliability: The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.

Combination valve/actuator: Refer to the valve documentation for suitable valves, their permitted medium temperatures and closing pressures.

Position indication: The stroke is indicated mechanically on the bracket with tabs. The stroke range adjusts itself automatically during operation.

Home position: Factory setting: Actuator spindle is retracted. The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out an adaption, which is when the operating range and position feedback adjust themselves to the mechanical setting range. The actuator then moves into the position defined by the positioning signal.

Direction of stroke switch: When actuated, the direction of stroke switch changes the running direction in normal operation.

Adaption and synchronisation: An adaption can be triggered manually by pressing the „Adaption“ button or with the PC-Tool. Both mechanical end stops are detected during the adaption (entire setting range). Automatic synchronisation after pressing the gearbox disengagement button is configured. The synchronisation is in the home position (0%). The actuator then moves into the position defined by the positioning signal. A range of settings can be adapted using the PC-Tool (see MFT-P documentation)
