Weidmuller PTX800A - Configurable counter and totalizer - Handbuch (Seite 32)


Totalscalingfactor
The total scaling factor sets the ratio between the total display and the
rate display. It must be a power of ten (i.e., 1000, 100, ..., 0.01, or 0.001).
Numberofsamples
The PTX800A calculates the rate every 60 mS. The analogue output
and display are then updated from the average over the programmed
number of samples. For example, if you set the number of samples to
10, the analogue output and rate display will be updated every .6 s.
Ratetimebase
The rate timebase setting sets the timebase for the rate display. It can
be set to days, hours, minutes or seconds.
Displayrateortotal
Use the display rate/total setting to choose the measurement that will
normally be on display.
EnableResetkey
The front panel reset key can be used to reset the total. You can
disable this feature (for added security) using this setting.
Alarmsdisable/enable
If you do not need alarms, you can disable them. This simplifies the
setup process, as all of the parameters related to the alarm operation
are skipped.
Alarmtype
Each alarm channel can monitor the total or the rate. Total alarms
operate when the setpoint is exceeded. A ‘total’ alarm trip condition
clears when the total is reset.
Setpoint
The setpoint is the display value at which an alarm activates. It can be
changed during normal operation if the setpoint security option is off.
