8 Maintenance and fault rectification

VEGAPULS 66 • 4 … 20 mA/HART - two-wire

28438-EN-170927

8 Maintenance and fault rectification

8.1 Maintenance

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

normal operation.

8.2 Rectify faults

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

ures to rectify faults.

VEGAPULS 66 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 measures to be taken are to check the output signals as well

as to evaluate the error messages via the display and adjustment

module. The procedure is described below. Further comprehensive

diagnostics can be carried out on a PC with the software PACTware

and the suitable DTM. In many cases, the causes can be determined

and the faults rectified this way.

Should these measures not be successful, please call in urgent cases

the VEGA service hotline under the phone no.

+49 1805 858550

The hotline is manned 7 days a week round-the-clock. Since we offer

this service worldwide, the support is only available in the English

language. The service is free, only standard call charges are incurred.

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 stable

Level fluctuations

Set damping via the display and adjustment module

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

In Ex applications, the regulations for the wiring of intrinsically safe

circuits must be observed.
