21* Required transit time
OPEN (w ramp open)
[0] to 240 s, ESC
Time required to move through the operating range when the valve
opens.
Limitation of the transit time (Code 21 and 22):
For some applications it is recommendable to limit the transit time of
the actuator to prevent it from engaging too fast in the running pro-
cess.
Code 21 has priority over Code 15.
NOTICE !
The function is not activated when the fail-safe function or solenoid
valve is triggered nor upon failure of the auxiliary power.
22* Required transit time
CLOSED (w ramp closed)
[0] to 240 s, ESC
Time required to move through the operating range when the valve
closes.
Code 22 has priority over Code 14.
NOTICE !
The function is not activated when the fail-safe function or solenoid
valve is triggered nor upon failure of the auxiliary power.
23* Total valve travel
[0] to 99 · 10 7 , RES, ESC
Exponential reading from
9999 travel cycles on -
wards
Totaled full valve travel cycle
Can be reset to 0 by selecting RES.
Note
The total valve travel is saved in a non-volatile memory after every
1000 full valve travel cycle.
