  • Page 7: Operating Function

    If the measuring point is mounted on DA 56 the differential pressure over the load can be measured by using the balancing instrument TA-CBI or measuring instrument TA-CMI. Installation of balancing valve STAD (STAF) is recommended to enable flow measurement, commissioning and troubleshooting with TA-CBI/TA-CMI.
  • Page 8 Setting DN 15-50 . Unscrew the fixing screw (4) - Allen key 2 mm - on setting wheel (). 2. Turn the setting wheel clockwise to increase the differential pressure and vice versa. 3. On the setting wheel there is a mark which shows how much Dp changes at one turn of the setting wheel.
