7  Diagnostics and servicing

7.1 Maintenance

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

normal operation.

The cleaning helps that the type label and markings on the instrument 

are visible.
Take note of the following:

• 

Use only cleaning agents which do not corrode the housings, type 

label and seals

• 

Use only cleaning methods corresponding to the housing protec-

tion rating

7.2  Rectify faults

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

ures to rectify faults.

Maximum reliability is ensured. Nevertheless, faults can occur during 

operation. These may be caused by the following, e.g.:

• 

Voltage supply

• 

Interference in the cables

The first measure to be taken is to check the input/output signal as 

well as the power supply. In many cases, the causes can be deter-

mined and faults can be quickly rectified.

Depending on the reason for the fault and the measures taken, the 

steps described in chapter " 

Setup

" must be carried out again or must 

be checked for plausibility and completeness. 

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 also available outside normal working hours, seven 

days a week around the clock.

Since we offer this service worldwide, the support is provided in 

English. The service itself is free of charge, the only costs involved are 

the normal call charges.

7.3  How to proceed if a repair is necessary
