8. Maintenance
Maintenance work is restricted to removing the sensor from the process now and again and cleaning
any accumulated particles off the probe and the insulation section using a cloth.
This is designed to prevent accumulated material resulting in bridge formation against the earthed
environment since this has a signicantly adverse effect on the measurement. The other aim is to
prevent the probe becoming encased with accumulated material.
If the particles tend heavily towards accumulation the maintenance work should be carried out more
frequently. No maintenance work is required in the sensor housing or on the Evaluation unit.
9. Warranty
On condition that the operating conditions are maintained and no intervention has been made on
the device and the components of the system are not damaged or worn, the manufacturer provides
a warranty of 1 year from the date of delivery.
In the event of a defect during the warranty period, defective components will be replaced or
repaired at ENVEA Process plant free of charge as considered appropriate. Replaced parts will
become ENVEA Process property.
If the customer requests that parts be repaired or replaced at his site, the customer must pay the
travel expenses for ENVEA Process service personnel.
ENVEA Process cannot accept any liability for damage not suffered by the goods themselves and
in particular ENVEA Process cannot accept liability for loss of prot or other nancial damages
suffered by the customer.

10.1 Response to errors
• SYS_VITAL_ERR describes caking on the sensor and can be rectied by cleaning at the
customer.
- bridging occurring short-term is also detected
- indicated for at least 1 minute
- adjustable at the sensor (Service function)
• All other errors are serious hardware faults and cannot be rectied by the customer. The sensor
must be returned to the factory.
