7 Maintenance and fault rectification

7.1 Maintenance

If the device is used properly, no special maintenance is required in

normal operation.

7.2 Rectify faults

The operator of the system is responsible for taking suitable meas-

ures to rectify faults.

SITRANS LVL200E offers maximum reliability. Nevertheless, faults

can occur during operation. These may be caused by the following,

e.g.:

•

Sensor

•

Process

•

Voltage supply

•

Signal processing

The first measure to take is to check the output signal. In many cases,

the causes can be determined this way and the faults quickly rectified.

Error

Reason

Rectification

SITRANS LVL200E sig-

nals "covered" without

being submerged (overfill

protection)
SITRANS LVL200E sig-

nals "uncovered" when

being submerged (dry run

protection)

Operating voltage too low Check operating voltage
Electronics defective

Press the mode switch on the signal conditioning in-

strument. If the instrument then changes the mode, the

vibrating element may be covered with buildup or me-

chanically damaged. Should the switching function in

the correct mode still be faulty, return the instrument

for repair.
Press the mode switch on the signal conditioning in-

strument. If the instrument then does not change the

mode, the electronics module is defective. Exchange

the electronics module.

Unfavourable installation

location

Mount the instrument at a location in the vessel where

no dead zones or air bubbles can form.

Buildup on the vibrating el-

ement

Check the vibrating element and the sensor for buildup

and remove the buildup if there is any.

Wrong mode selected

Set the correct mode on the signal conditioning instru-

ment (overflow protection, dry run protection). Wiring

should be carried out according to the idle current prin-

ciple.

Control lamp off

Error on the vibrating el-

ement

Check if the vibrating element is damaged or extreme-

ly corroded.

Interference on the elec-

tronics module

Exchanging the electronics module

instrument defective

Exchange the instrument or send it in for repair

tion occurs
