'44.AFCT' Alarm function

Possible settings:
Purpose:
Factory setting:
160
● BIN1 or BIN2 =
contact uP or doWn closes, or
contact -uP or -doWn opens
If the binary input is activated, the actuator uses the value defined
by the "'35.YA' Start of manipulated variable limit / '36.YE' End
of manipulated variable limit (Page 155)" parameter for
controlling in "Automatic" mode.
● BIN1 or BIN2 contact closes = StoP or -StoP contact opens
In "Automatic" mode, the piezo valves are blocked when the
binary input is activated. 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 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
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, the firmware version is displayed when the button
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".
OFF
See representation below
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 via the communication interface.
The direction of action of the binary outputs can be adjusted from
"High active" to "Low active" for the next system.
