5.1 Simulation
Test switch (option with E30 R, C, T)
As an option, a test switch can be integrated
in the housing to simulate a switching condi-
tion.
By turning on the test switch, an additional
capacitance is provided. Through this, the
function of the oscillator and the connected
instruments can be tested.
The numbers in parantheses relate to the
illustration "Adjustment elements“.
Note
When the changeover switch (6) is set to
position 3, it is possible that the additional
capacitance is not sufficient to carry out a
test.
The test switch can only be used for simula-
tion of a max. level (overfill protection).
Test
• Make sure that the A/B-switch (4) is set to
position A. In normal operation, the test
switch is set to position 0.
• Set the test switch to position 1. Turning the
test switch to position 1 increases the ca-
pacitance of the uncovered electrode,
causing the oscillator to respond and trig-
ger an alarm signal; the control lamp (2)
lights and the connected instruments are
activated.
Note
It is absolutely necessary to set the test
switch to its initial position (position 0) after
the test.
5.2 Maintenance
The instrument is maintenance free.
5.3 Repair
Repair work usually involves opening the
instrument to diagnose and correct defects.
For safety and warranty reasons, any internal
work on the instrument, apart from installation
and wiring, must be carried out only by
VEGA personnel.
In case of a defect, please return the respec-
tive instrument with a short description of the
error to our repair department.
