9.4 Rectify faults

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

ures to rectify faults.

The first measures are:

•

Evaluation of fault messages via the adjustment instrument

•

Checking the output signal

•

Treatment of measurement errors

Further comprehensive diagnostics options are available with a PC

with PACTware and the suitable DTM. In many cases, the reasons can

be determined in this way and faults rectified.

Connect a multimeter in the suitable measuring range according to

the wiring plan. The following table describes possible errors in the

current signal and helps to eliminate them:

Error

Cause

Rectification

4 … 20 mA signal not sta-

ble

– Fluctuations of the

measured variable

– Set damping appropriate to the instrument via the

display and adjustment module or PACTware/DTM

4 … 20 mA signal missing

– Electrical connection

faulty

– Check connection according to chapter "

Connection

steps

" and if necessary, correct according to chapter

Wiring plan

– Voltage supply missing

– Check cables for breaks; repair if necessary

– Operating voltage too

low or load resistance

too high

– Check, adapt if necessary

Current signal greater than

22 mA or less than 3.6 mA

– Electronics module in

the sensor defective

– Exchange the instrument or send it in for repair

The below tables show typical examples of application-related meas-

urement errors with liquids. The measurement errors are differentiated

according to the following:

•

Constant level

•

Filling

•

Emptying

The images in column "

Error pattern

" show the real level as a broken

line and the level displayed by the sensor as a continuous line.

Reaction when malfunc-

tion occurs

Procedure for fault recti-

fication
