6 Inputs and outputs
32 Positioner DC 6-06
A switch pulse must be at least 20 ms long to be detected by the control
electronics.
Digital inputs are not monitored for errors and must
not be used for safety-related functions as defined by
classification societies
Therefore it is recommended to use a monitored analogue
input instead of a digital input for the external stop request
( 5.2.1.2 External stop request by an analogue input).
6.2 Setpoint selection and stop request via analogue inputs
Analogue input 3 is permanently assigned by the system for the connection of an analogue
setpoint generator 4330 FuelSetpPWMOrAnalog = 0. The input stays open when a PWM
setpoint is used 4330 FuelSetpPWMOrAnalog = 1.
If an analogue stop request is necessary (4847 AnaStopRequestUsed = 1), analogue input 1
must always be used because it is permanently assigned by the system.

6.2.1 Adjusting the current/voltage inputs
Each of the current/voltage inputs has a lower (1510 AnaStop_Ref_0% or 1530
FuelSetAna_Ref_0%) and an upper reference value (1511 AnaStop_Ref_100% or 1531
FuelSetAna_Ref_100%). These two values in this order basically correspond to the 0 %
and 100 % value of the sensor/setpoint generator irrespective of which current or
voltage is to be externally applied. The current unfiltered value of the analogue input is
displayed in 3511 AnaStop_Value or 3531 FuelSetpAna_Value and the filtered value in
3510 AnaStop_Percent or 3530 FuelSetpAna_Percent. The filtered values correspond
directly to the displayed values in 2900 AnaStopSensor or 2350 FuelSetpoint.
