Meaning of the diagnostics values
1 STRKS - Number of strokes
In operation, the movements of the actuator are summed up and displayed in this
diagnostics value as the number of strokes. Unit: 100% strokes, i.e. the path between 0 and
100% and back. The value is written in a non-volatile memory every 15 minutes. The non-
volatile memory can be set to zero using the
button.
2 CHDIR - number of changes of direction
Every change of direction of the actuator caused in the deadband is noted in the closed-loop
controller and added to the number of changes of direction.
The value is written in a non-volatile memory every 15 minutes. The non-volatile memory
can be set to zero using the
button.
3 CNT - number of fault messages
Every fault is noted in the closed-loop controller and added to the number of fault messages.
The counter can be set to zero using the
button.
4 A1CNT - Number of alarms 1 and
5 A2CNT - Number of alarms 2
These two counters indicate how often alarms 1 and 2 have been triggered. Activation of
alarms using the "AFCT" parameter is a requirement for this. The counters can be set to
zero using the
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. Requirement for linear actuators: Specification
of the lever arm using the "YWAY" parameter.
8 TUP - Response time open and
9 TDOWN - Response time closed
These values indicate the actuating times determined during the initialization process. The
unit is seconds.
