PROFIBUS-PA User + Installation Guideline
(PNO document 2.092).
At the binary input, a passive floating con-
tact can be used. The positioner signals the
circuit status via the bus protocol.
NOTE
The connection of limit switches, binary
input and forced venting function requires
an additional cable gland that must replace
the cap fitted on the housing.
Accessories:
Cable gland M20 x 1.5, nickel-
plated brass, order no. 8808-0143
3.2.1 Forced venting
For positioners with forced venting function,
a voltage of 6 to 24 V DC must be applied
to the relevant terminals.
The forced venting function can be acti-
vated or deactivated over an internal
switch. See chapter 4.3 for more details.
CAUTION
If there is no voltage connected or when the
voltage signal is interrupted, the positioner
vents the actuator and does not respond to
the reference variable.
