Adaption of stroke range
The first time the supply voltage is switched on, i.e. at the time of commissioning, the
actuator carries out a stroke adaption, which is when the operating range and position
feedback adjust themselves to the mechanical stroke.
Manual triggering of the adaption can be carried out by pressing the "Adaption" button
or with the PC-Tool.
Rotary knob emergency setting
position
The "Emergency setting position" rotary knob can be used to adjust the desired
emergency setting position (POP) from 0% to 100% in 10% increments.
The rotary knob is in reference to the adapted or programmed height of stroke.
In the event of an electricity interruption, the actuator will move into the selected
emergency setting position, taking into account the bridging time (PF) of 2 s which was
set ex-works.
Settings: The rotary knob must be set to the "Tool" position for retroactive settings of
the emergency setting position with the BELIMO service tool MFT-P. Once the rotary
knob is set back to the range 0 … 100%, the manually set value will have positioning
authority
Bridging time (PF)
Electricity interruptions can be bridged up to a maximum of 10 s.
In the event of an electricity interruption, the actuator will remain stationary in
accordance with the set bridging time. If the electricity interruption is greater than the
set bridging time, then the actuator will move into the selected emergency setting
position (POP).
The bridging time set ex-works is 2 s. This can be modified at the site of operations
with the use of the BELIMO service tool MFT-P.
Settings: The rotary knob must not be set to the "Tool" position!
Only the values need to be entered for retroactive adjustments of the bridging time
with the BELIMO service tool MFT-P.
