Test of software limit switch alarms A1 and A2 as well as of fault
alarm contact A3.
Ifthetestisactivated,thecontactisswitchedvetimes.
RUN1/1RUN:softwarelimitswitchA1to≥2.2mA

RUN3/3RUN:faultalarmcontactA3to≤1.0mA
29* Position transmitter x/ix
3)
[ää], äæ, ESC
Operating direction of the position transmitter: it indicates assign-
mentbetweentravel/anglepositionandoutputsignalibasedon
CLOSED position.
Theoperatingrange(seeCode8)ofthevalveisrepresentedbythe
4to20mAsignal.Valuesexceedingorfallingbelowthelimits2.4
and21.6mAcanbeindicated.
Whenthepositionerhasnotbeenmounted(setpointsmallerthan
3.6mA),thesignalis0.9mAand3.8mAthepositionerhasnot
beeninitialized.WhenYESissetinCode32,thepositiontransmit-
terissuesthevalueasperCode30duringinitializationorzerocali-
bration.WhenNoissetinCode32,4mAisissuedduringarun-
ning calibration.
30* Fault alarm ix

HI, LO, [No], ESC
Select if and how alarms that cause the fault alarm contact to be
switched are also indicated by the position transmitter.

the operating range.
The momentary valve position is used in initialized positioners local-
lyasthestartvalue(bumplesschangeovertothetestmode).When
testing by software, the entered simulation value is issued as the po-
sition feedback signal for 30 seconds.
