Code 18
Fail-safe action of the actuator upon air/auxil-
iary power failure or device start-up.
Determined during initialization by the position
of the slide switch (see section 5.1).
In double-acting actuators, the fail-safe position
relates only to the failure of the auxiliary power
supply. There is no defined position when the
supply air fails.
Code 19
Reset criterion for running control loop moni-
toring.
A control loop error is issued when the delay
time is exceeded and the system deviation is not
within the tolerance band.
