The damper actuator type 227VM contains a dyna-mic differential pressure sensor. The volume flow is measured according to the defined flow directi- on. An integrated microprocessor controls measu- rement and control of the actuator and communi- cations. For pressure independent control of VAVboxes. The actuator controlled by proportional con-trollers, ositioners or DDC systems. Simple realisa- tion of different operating modes can be utilised by using override control signals. > Nominal voltage 24 VDC / 24 VAC 19,2...30,0 VDC / 19,2...28,8 VAC Motion (Power safe mode)2.5 W / 4,0 W / 6,5...

Flow / Unit Shows the actual flow in m3/h, l/s, cfm or % and Diag for diagnosis. This display matches with the feedback signal U. The display starts flashing if the servomotor hits an end stop before matching actual to reference flow. An overflow (higher pressure as 250Pa = 1.0inWC) is indicated in the display by a small circle. Turning the value selector allows unit selection. The appropriate dot is toggled as indicator. The units are converted according to the given precision as described below (see Vnom). Vmin Allows to set the desired minimum flow for the external reference signal Y=0V...
