337
8000 Error during digital position feedback. Actuator_H = TRUE and Actuator_L = TRUE.
The actuator cannot be moved to the substitute output value and remains in its current position. Manual
mode is not possible in this state.
In order to move the actuator from this state, you must deactivate the "Actuator endstop" (Con-
fig.ActuatorEndStopOn = FALSE) or switch to manual mode without endstop signals (Mode = 10).
If automatic mode was active before the error occurred, ActivateRecoverMode = TRUE, and the error is
no longer pending, PID_3Step switches back to automatic mode.
If pretuning, fine tuning, or transition time measurement mode and ActivateRecoverMode = TRUE were
active before the error occurred, PID_3Step switches to the operating mode that is saved in the Mode
10000 Invalid value at ManualValue parameter. Value has an invalid number format.
The actuator cannot be moved to the manual value and remains in its current position.
Specify a valid value in ManualValue or move the actuator in manual mode with Manual_UP and Manu-
20000 Invalid value at SavePosition tag. Value has an invalid number format.
The actuator cannot be moved to the substitute output value and remains in its current position.
40000 Invalid value at Disturbance parameter. Value has an invalid number format.
If automatic mode was acti
ve and ActivateRecoverMode = TRUE before the error occurred, Disturbance
is set to zero. PID_3Step remains in automatic mode.
If pretuning or fine tuning mode was active and ActivateRecoverMode = TRUE before the error oc-
curred, PID_3Step switches to the operating mode saved in the Mode parameter. If Disturbance in the
current phase has no effect on the output value, tuning is not be canceled.
The error has no effect during transition time measurement.
