6. Exercising and Cleaning
6a. Weekly Exercising
To ensure continued smooth valve movement, the valve
should be operated (exercised) once a week over its entire
operating range.
6b. Cleaning
Use a damp cloth to clean the actuator.
Do not use any detergent or chemical product that may
seriously damage or compromise the function of the valve.
6c. "Error" in Actuator's Display
If the actuator's shaft encounters excessively high torque, the
digital display of the V5004TF actuator will show:
Fig. 4. "Error" in actuator display
This can be caused by:
• The valve (which may be worn-out or defective);
• Manual operation while the actuator is powered.
After correcting the cause of the error, reset the ERROR
display by pressing the UP and DOWN buttons simul-
taneously for 3 seconds.
6d. Cleaning the Valve's Adjustment Screw
The adjustment screw of the V5004T Kombi-QM should be
cleaned regularly – usually, once annually or after every 5,000
cycles. Under certain environmental and operational con-
ditions, it may be necessary to perform this task more
frequently.
6e. Dismounting the Actuator
To dismount the actuator, proceed as follows:
Turn the connection ring between the valve and the actuator
and remove the actuator.

NOTE:
To avoid damage due to condensation from the
valve stem, be sure that the actuator is not
mounted upside down. Please note that care must
be taken when installing the actuator: Even only
minor angular deviations can compromise proper
actuator operation.
7. Initial Setting
Upon powering up the device, the display indicates "Go-0"
and the initial setting to the valve zero point is automatically
adjusted.
Do not press any buttons during this adjustment process as
this might interfere with the automatic adjustment of the initial
setting of the valve zero point and thus result in incorrect flow
control.
How to set: To enter the setting mode, press the MODE
button several times until the required setting is displayed
(e.g., S-01). After 2 s, the value of the selected setting is
displayed and can now be changed, if desired, using the UP
and DOWN buttons. After changing the value, you must press
the MODE button within 5 s in order to save the changed
value – otherwise, the change will not be saved and the
display will return to its basic value.
