7 Maintenance and fault rectification
7.1 Maintenance
If the instrument 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.
VEGASWING 51 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 be taken is to check the output signal. In many
cases, the causes can be determined this way and the faults rectified.
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 available to you 7 days a week round-the-clock. Since
we offer this service world-wide, the support is only available in the
English language. The service is free of charge, only the standard
telephone costs will be charged.
Error Cause Rectification
Green signal
lamp off
Voltage supply in-
terrupted.
Check the voltage supply and the ca-
ble connection
Electronics de-
fective
Exchange the instrument or send it in
for repair
Red signal lamp
lights (switching
output high-im-
pedance)
Error with the
electrical con-
nection
Connect the instrument according to
the wiring plan
Shortcircuit or
overload
Check the electrical connection
Red signal lamp
flashes (switching
output high-im-
pedance)
Virbating fre-
quency out of
specification
Check the vibrating element on build-
up and remove it
Buildup on the vi-
brating element
Check the vibrating element and
the sensor if there is buildup and re-
move it
Vibrating element
damaged
Check if the vibrating element is dam-
age or extremely corroded
Depending on the reason for the fault and the measures taken, the
steps described in chapter "Set up" may have to be carried out again.
