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.

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
.
