Your call has been recorded under the GDAP-Hotline Case HLC0162. Please use this number for further follow-ups. Would you please provide the name of the customer?
This error refers to the thickness sensor in the sensor unit. Please try to clean the holes/felts and restart the BPS C4. If the error still occurs please try to replace a spare sensor unit.
If the error disappears with the new sensor then the old sensor needs to be repaired. Please kindly provide feedback. Thank you.
