Undesired movement of the connected actuators and
non−defined switching states of the electronics can cause
personal injury or material damage.
Before carrying out installation and/or maintenance work,
switch off the following in the sequence specified:
1. Compressed air supply
2. Line voltage supply of the HGPPI−... internal electronics.
C au tion
Pressures above 6 bars can destroy internal components.
Observe the permissible operating pressure range.
Note
Please note that the maximum permitted bus length
depends on the baud rate. The allocation of the baud
rate to the bus length can be found in Table3/3.
A bus segment is a bus cable which may contain up to
32 stations (devices). The ends of the bus segment must
be fitted with a terminating resistor. Use plugs with a built−in
terminating resistor if the HGPPI−... is installed at the end of
a bus segment.
