6.7 Digital inputs
The GEMÜ 1436 cPos makes it possible to use digital inputs
for specic functions.
It is also available to order with two exclusively digital inputs. In
addition to this, it provides the option of using the actual value
and set value inputs as digital inputs under certain conditions.
The wiring information under 6.7.1 only applies when the
GEMÜ 1436 cPos is used without the optional digital input
card.
The digital inputs facilitate the use of dierent functions to
control the positioner in addition to the analogue control
signals. For example, this means up to four parameter sets with
dierent settings can be stored and called up by two digital
inputs through a logical connective (ParmSet Bx function).
The positioner can be stopped by the signal from a digital input
(automatic control system deactivated, current valve position is
maintained) or started up by the valve safety position (function
OFF/ON or Safe/On). Furthermore, the output source of the
analogue actual value output is controlled externally (function
Poti/Ix).
On the Probus DP and DeviceNet eldbus versions, the digital
input functions can be used in addition as standard and do not
need to be ordered separately.
