Troubleshooting

Malfunction

Possible reasons

Recommended action

Temperature at the

sensor exceeds the

set point.

Seat and plug are worn or leak.

Clean the seat and plug.

Replace the damaged seat and plug.

Contact SAMSON's After-sales Service.

Foreign particles blocking the plug

Remove foreign particles.

Replace damaged parts.

Contact SAMSON's After-sales Service.

Sensor installed in the wrong location.

Change the mounting position.

Sensor installed incorrectly.

Immerse the temperature sensor with its entire

immersion depth in the process medium.

Avoid an installation site where idle times or

heat buildup can occur.

Regulator or K

coefficient too large

Check the sizing.

Change K

coefficient, if necessary or

install a different sized regulator.

Contact SAMSON's After-sales Service.

Control thermostat defective

Replace the control thermostat.

Temperature at the

sensor fluctuates.

Regulator or K

coefficient too large

Check the sizing.

Change K

coefficient, if necessary or

install a different sized regulator.

Contact SAMSON's After-sales Service.

Sensor installed in the wrong location.

Change the mounting position.

Sensor installed incorrectly.

Immerse the temperature sensor with its entire

immersion depth in the process medium.

Avoid an installation site where idle times or

heat buildup can occur.

Slow control

response

Time constant is too large for the control

loop.

Fill the thermowell with thermal paste or

remove the thermowell.

Use a sensor with smaller time constant (e.g.

vapor pressure thermostat).

Sensor installed incorrectly.

Immerse the temperature sensor with its entire

immersion depth in the process medium.

Avoid an installation site where idle times or

heat buildup can occur.
