'41.AFCT' Alarm function

Possible settings:
Purpose:
Factory setting:
164
● BIN1 = bLoc1
Use this parameter value to interlock the "Configuration" mode
against adjustment. The lock is performed e.g. with a jumper
between terminals 9 and 10.
● BIN1 = bLoc2
If binary input 1 has been activated, the "Manual" as well as
"Configuration" modes are blocked.
● 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 "'32.YA' Manipulated variable limiting Start / '33.YE'
Manipulated variable limiting End (Page 160)" 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 will be displayed when the mode button
is pressed.
If one of the above functions is activated simultaneously with the
"BIN1" and "BIN2" parameters, then: "Blocking" takes priority over
"uP". "uP" takes priority over "doWn". "doWn" takes 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.
