9 TROUBLE 

SHOOTING 

When problems occur start checking the following: 

−

Validate that parameters in OVP software are suitable for the application. Start the OVP program and 
check important settings such as closing direction, working range and torque/force. 

−

Validate that the actuator is properly mounted on the valve. 

−

Validate that the valve is not blocked or jammed within the working range. 

A)  

Nothing happens when changing the control signal value 

1.

Check power, 24 V DC ± 15%. 

2.

Check the control signal, 4-20 mA. 

3.

If the surface of the actuator gets hot after 5 - 10 minutes, check that the “Shut-off” value in OVP is 
set to default 5 % of working range. 

4.

If you are controlling a turning valve, try to move the valve spindle by hand using a treaded M10 -pin 
in the clamp collar: 

a.

If you cannot move the valve spindle, break the 24 V and try again. 

b.

If you still cannot move the spindle, remove the Basic Unit and try to move the valve by hand. 

c.

If it is still a problem to move, examine the valve. 

d.

If the valve moves easily, check if there is any sticking force between valve and actuator. If not, 
remove the actuator and run it free. If nothing happens contact Oden. 

e.

If the actuator is running constantly and cannot be controlled, go to 6. 

5.

Perform a new Manual Power Calibration. 

6.

Still nothing happens. The actuator may be in a Power Calibration routine which has been interrupted. 
Turn off power to break the routine. Exit OVP and start the program again. Perform a Manual Power 
Calibration. (You might need a mechanical stop.) 

B) 

When giving the control signal maximum value the actuator gets hot 

1.

Check if the position signal is the same as the control signal (20 mA). The normal maximum 
difference between these two values should be <0.1 mA.  If it is larger, then the available mechanical 
working range is probably smaller than the working range setting in OVP (blocking situation). Reduce 
the working range in OVP to a value 5 degrees (for linear actuators 3 mm) lower than the available 
mechanical working range.  
There is a built-in safety temperature sensor which will stop the function of the actuator when the 
temperature exceeds maximum limit.. The power will reset when the actuator has cooled down. 

2.

Validate that the valve is not blocked or jammed within the mechanical working range. 

3.

Validate that the necessary torque (force) to move the valve is within what the actuator can deliver. 

C) 

No connection to OVP 

1.

Exit the OVP program and start again. 

2.

OVP 3.8: Check that the data cable is connected to the connection board and computer port and that 
the port is logical opened. If using an USB-serial adapter, try to direct it to port number 3.  
OVP 4.1: Try another serial port in the main menu. Connect the actuator and perform a power 
calibration by pressing the button “Power Calibration”. If the calibration fails, go to main menu and 
choose another serial port. 

3.

Check power, 24 V DC ± 15%
