● BIN1 or BIN2 = PSt or -PSt
Using binary inputs 1 or 2, a partial-stroke test can be triggered by actuation of your
choice of a normally closed or normally open switch.
● BIN1 or BIN2 = OFF (factory setting)
No function
Special function of binary input 1: If binary input 1 is activated in "P-manual mode" by
means of a jumper between terminals 9 and 10, then when the mode button is pushed
the firmware version will be displayed.
If one of the above functions is activated with the "BIN1" and "BIN2" parameters
simultaneously, then: "Blocking" has priority over "uP" and "uP" has priority over "down".
10.4.2.14 Description of parameters 44
44.AFCT - Alarm function
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 alarm module. In addition, alarms can also be
read out over the HART communicator (optional).
The direction of action of the binary outputs can be adjusted from "High active" to "Low
active" for the next system.
