● BIN1 or BIN2 =
Contact uP or doWn closes or
Contact -uP or -doWn opens
If the digital input is activated, the actuator uses the value de‐
fined by the "'35.YA' Start of manipulated variable limit / '36.YE'
End of manipulated variable limit (Page 151)" parameter for
controlling in 'Automatic' mode.
● BIN1 or BIN2 =
Contact StoP closes or
Contact -StoP opens
When the digital input is activated, controlling the pneumatic
block is blocked in "Automatic" mode. The actuator remains at
the last position. Leakage measurements can be performed in
this way without using the initialization function.
● BIN1 or BIN2 = PSt or -PSt
Using the digital input DI1 or DI2, a partial stroke test can be
triggered by actuation of either a normally closed or normally
open contact.
● BIN1 or BIN2 = OFF
No function
Special function of digital input DI1: If digital input DI1 is activa‐
ted in 'P-manual mode' by means of a jumper between terminals
9 and 10, the firmware version will be displayed when the
button is pressed.
If one of the above functions is activated simultaneously with the
"BIN1" and "BIN2" parameters, then: "Blocking" has priority over
"uP". "uP" has priority over "doWn". "doWn" has priority over "PST".
Factory setting: OFF
8.4.2.15 '44.AFCT' Alarm function
Possible settings: See corresponding representation below
Purpose: This parameter can be used to determine the value at which going
above or below a given offset or angle will result in a message. The
triggering of alarms (limits) is relative to the MPOS scale. Alarms
are signaled through the Digital I/O Module (DIO). In addition,
alarms can also be read via the communication interface.
The direction of action of the digital outputs can be adjusted from
"High active" to "Low active" for the next systems.
Factory setting: OFF
