CONNECTION CONFIGURATION
LEDs to indicate the operating mode
Default configuration
POWER LED lights The device is supplied with
(green) operating voltage.
flashes Autotune function activated.
LIMIT (y) LED lights With MFC:
(blue) indicates that the correcting
variable of the valve has almost
reached 100 %. In practice, this
usually means that the pressure at
the controller is insufficient to
realize the desired flow rate.
With MFM:
indicates that the process value has
almost reached the nominal flow
rate.
flashes The device is in an operating mode
other than control or Autotune.
with fieldbus
devices:
COMMUNI- lights The device communicates via bus
CATION LED or RS232.
(yellow)
ERROR LED lights Not a serious error, e.g. Autotune
(red) not completed successfully or faulty
LED.
flashes Serious error, e.g. sensor breakage
or faulty internal voltage supply.
