Changing The Type Of Protection - ABB CoriolisMaster FCB330 Instrucciones De Uso

Carrying out the check
1. Switch off the power supply and wait for at least two
minutes before opening the housing.
2. Remove a cable gland which is not being used. Cable
glands certified to ATEX or IECEx are usually used,
e.g., M20 x 1.5 or 1/2" NPT thread.
3. Connect the device being used to test the pressure in
place of the cable gland you removed. Check that the test
device has been installed and sealed correctly.
4. Carry out the test with the test device (see chapter
"Important notes to test the device").
5. Remove the test device and put the cable gland back in
place correctly.

Changing the type of protection

When installed in DIV 1 / Zone 1 the FCB330/350, FCH330/350 and FCT330/350 models can be operated at Signal Data
INPUT / OUTPUT
with different types of protection:
— Signal Data INPUT / OUTPUT as intrinsically safe ia (ib) / IS or
— Signal Data INPUT / OUTPUT as non-intrinsically safe
Initial installation
DIV 1 / Zone 1:
Signal Data
INPUT / OUTPUT as non-
intrinsically safe
DIV 1 / Zone 1:
Signal Data
INPUT / OUTPUT as
intrinsically safe ia (ib) / IS

Before the power supply is switched on again, the housing,
seals, thread, and cable entries must be subjected to a visual
inspection. There must be no evidence of damage.
IMPORTANT (NOTE)
For sealing original spare parts should be used
only.
Spare parts can be ordered from ABB Service:
Please contact Customer Center Service acc. to
page 1 for nearest service location.
IMPORTANT (NOTE)
When selecting a location for the transmitter,
make sure that it will not be exposed to direct
sunlight.
If exposure to direct sunlight cannot be avoided,
a sun shade should be installed.
The limit values for the ambient temperature must
be observed.
