Alarm counter 1
and
Alarm counter 2
Responses of alarm 1 and alarm 2 are counted with these two
counters. The prerequisite is the activation of the alarms with the
parameter ”40.AFCT”. The counters can be reset to zero with the
increment key
.
Operating hours
The operating hours counter is updated every hour as soon as the
positioner has been supplied with electrical power.
Determined actuating way
This value indicates the actuating way determined during initialization
according to the display at the end of an initialization. Prerequisite in
linear actuator: Specification of the lever arm with the parameter
”3.YWAY”.
Travel time up
and
travel time down
These values show the travel times which have been determined
during initialization. The unit is seconds.
Leakage
The value of the leakage measurement in %/min. can be read off here.
This measurement may take place during the initialisation phase or
here in this diagnostic menu.
The leakage measurement starts when the increment key is pressed
for more than 5 s and then released. During the measurement, the
value of the current position or ”tESt” is displayed interchangeably in
the upper line of the display. After 1 minute, the position change can be
read off in %/minute.
Note that the leakage measurement may only be started if the
positioner is in manual mode (”MAN”). If this is not the case, ”noMAn”
is displayed in the upper line of the display.
Potentiometer value bottom stop
and
Potentiometer value top stop
These two values indicate the measured values of displacement
measurement (potentiometer) at the bottom and top hard stops as
determined in automatic initialization. In manual initialization the values
of the manually reached limit positions are indicated here.
