Installation
5.1 Vacuum connection
Mounting orientation
The installation position can be freely selected. The preferred position is a horizontal to
vertical position so that condensate and particles do not penetrate the measurement
chamber.
Connecting the trans-
mitter
Remove the protective cover, which is required during maintenance work.
Make the flange connection.
5.2 Electrical connection
Communication is effected, depending on the position of the address selector switch at
the transmitter, via Serial Interface RS-232 or via the RS-485 (address settable from 1-
15).
CAUTION
Vacuum component!
Dirt and damage impair the function of the vacuum component.
When handling vacuum components, ensure that they are kept clean and are protect-
ed against damage.
Ensure that the connection flange is clean, dry and free of grease.
CAUTION
Excess pressure in the vacuum system 1.5 to 4 bar
Damage to health through emission of process media, because elastomer washers
cannot withstand the pressure.
Use sealing rings with an outer centering ring.
CAUTION
Excess pressure in the vacuum system > 1 bar
Danger of injuries by inadvertent opening of elements under stress due to parts flying
around.
Only use stressed elements, which can be opened and closed with appropriate tools
(e.g. strap retainer-tension ring).
NOTE
Damage to the transmitter!
Only connect the connection cable when de-energized.
Never establish a connection to the transmitter using a live cable.
