7.4.12 Tactile Sensor
Table 7-12 Tactile Sensor Troubleshooting
Symptom Possible Cause Recovery
During setup routine,
error indicates that the
tactile sensor is already
engaged
Tactile sensor cap is stuck in the
down position.
Visually inspect the sensor cap for fluid buildup. If
there is fluid, clean the cap, see 7.4.13.1 Tactile
Sensor Error. If there is no fluid, contact Asymtek
Technical Support.
The tactile sensor signal can be tested from the
Fluidmove Tools > IO menu. Select IO and inputs.
Locate the tactile cap signal display and monitor its
state as the cap is depressed and released. If the
state does not change, the precision switch may
have failed.
Needle-to-height-sensor
offset is inaccurate
Fluid build-up on probe tip or
tactile sensor cap may have
caused inaccurate height sensor
calibration.
1. Clean probe tip/tactile sensor cap, see 7.4.13.1
Tactile Sensor Error.
2. Perform a “Valve Offsets” routine in Fluidmove.
For assistance, refer to the Fluidmove User
Guide or Fluidmove Online Help.

1. Gently lift the tactile sensor cap off of the tactile sensor.
2. Use isopropyl alcohol and a soft cloth to remove any residual fluid from around the
circumference of the cap, the tactile sensor opening and the sensor tip.
3. Replace the tactile sensor cap.
4. In the Main Window, click on
Tools.
5. In the Tools Window, click on
I/O Test.
