This pink colour seems that valve is in between condition.So we have to check the position of valve open and limit switch switch not acted or physically valve is in middle position.

Answer / elheiven

Up the torque limit then power cycle if the motor stalled is not working try to change main power pcb or power module

Answer / ejaz

Check the local display in the MOV. If valve have any issue it will show the exact error. for example MOTOR STALLED. MOTOR STOPPED. first check the phasically status on the local display

Q1: Consider part of a control loop, which excludes the transmitter, consisting of a process, a controller and a control valve which may be represented by two dead times of 0.5 min each and three exponential lags of 0.8 min., 1.0 min. and 1.5 min. respectively. We wish to express this system as an overall first order plus dead time (FOPLD) model ie gain, time constant and process dead time. (We will see later that this is often done, to simplify controller tuning). For this exercise, gain is considered to be 1.0. (A) If the transmitter is a flow transmitter whose behaviour can be described by a dead time of 0.2 min. and an exponential lag of 0.5 min. in terms of the overall dead time and overall first order lag how can the system behaviour be approximated ? Overall dead time = Overall time constant = (B) If the transmitter is a temperature transmitter with a temperature sensor in a protecting well whose behaviour can be described by a dead time of 0.7 min. and an exponential lag of 15 min. how can the overall system behaviour be approximated now? Overall dead time = Overall time constant =
