5 A2CNT - number of alarms 2
The response of alarms 1 and 2 is counted using these two counters. Activation of alarms
using the "AFCT" parameter is a condition for this. The counters can be set to zero using the
increment button.
6 HOURS - operating hours
The runtime meter is incremented every hour as soon as electric auxiliary power is supplied
to the positioner.
7 WAY - determined actuator travel
This value indicates the actuator travel determined during the initialization process as per the
display at the end of an initialization process. Conditions for lift actuators: Specification of the
lever arm using the "YWAY" parameter.
8 TUP - actuating time up
9 TDOWN - actuating time down
These values indicate the actuating times determined during the initialization process. The
unit is seconds.
10 LEAK - leakage
If a leakage measurement was initiated during the initialization process, the leakage value in
%/min can be read here.
11 PST - monitoring of the Partial-Stroke test
The measured step time of the last partial stroke test is displayed here. A partial stroke test
can be initiated manually or a current partial stroke test can be interrupted by pressing the
larger button.
The following statuses are shown on the digital display:
●
OFF
The partial stroke test function is deactivated in the configuration menu.
●
FdIni - Failed PST Initialization
The partial stroke test reference step time measurement has failed.
●
notSt - No Test
A Partial-Stroke-Test was not executed yet.
●
###.# (measured step time in seconds)
The last partial stroke test was successfully executed.
●
SdtSt - Stopped Test
The last partial stroke test was interrupted.
