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.
The factory settings cover the most common applications. Single parameters can be modified with the
Belimo Service Tools MFT-P or ZTH EU.
Simple direct mounting on the damper shaft with a universal shaft clamp, supplied with an anti-rotation
device to prevent the actuator from rotating.
Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or
remains locked).
Adjustable angle of rotation with mechanical end stops.
The actuator is overload protected, requires no limit switches and automatically stops when the end stop
is reached.
The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out
a synchronisation. The synchronisation is in the home position (0%).
The actuator then moves into the position defined by the positioning signal.
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)
