3.2 Function
The transmitter can be operated in conjunction with the DigiLine Controller, with the Di-
giLine Power Supply units and the WINDOWS1) based measuring software DokuStar
(please see "Accessories") on a PC or with customized, digital signal evaluation.
Communication is carried out, depending on the address selector switch setting, via the
serial RS-232 interface using the relevant display units or via RS-485 using the Pfeiffer
Vacuum protocol. The relevant bus adapters are available for connection to Profibus sys-
tems (see Accessories).
The transmitter responds to measurement value queries, type queries and setting com-
mands.

Transport and storage
4 Transport and storage
Units without external protection must not come into contact with electrostatically charge-
able materials and must not be moved within electrical or magnetic fields.
In rooms with moist or aggressive atmospheres, the unit must be airproof shrink-
wrapped in a plastic bag together with a bag of desiccant.
Keep the original protective covers.

Installation
5Installation
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.
