Totalizer Function and Display
The totalizer display can be accessed by selecting “Totalizing” in the Menu
(press the Menu button and use the up and down buttons to select).
Pressing the Menu button again will close the totalizer display.
The totalizer screen looks as follows:
When the totalizer display activated, the following settings can be
chosen:
(use the up and down buttons for selecting the display line “>”)
Button: Function:
@ line 1 press Enter for Channel select key (channel 1 to 4).
@ line 2 press Enter for Change totalizer status from “Disabled” into
“Running” or vice versa.
@ line 3 press Enter for Reset counter value (totalizer must be
in “Disabled” mode).
@ line 4 press Enter for This line displays the selected engineering unit.
When the text “Wrong ENG settings” is
displayed, the engineering unit selected is not
correct (the totalizer function needs a time
related engineering unit). In this case the Enter
button can be used to change the change
engineering unit to a time related unit
Menu: Leave the totalizer display function.
If totalizer is active (running mode) this is noticed on the standard display
mode by a “t” behind the channel number (example for channel 1: display
reads “1:t” or “1>t”).
Pressing the Enter button will activate the totalizer display, when a channel
indicates the “t” and this line is selected (indicated by “>”).
Max. Value
The totalizer value of the first line normally uses 7 positions and 5 positions
for the used engineering unit. If the totalizer value has more than 7
positions it uses up to max. 10 positions. The engineering unit is simply
shifted outside the range of the display.
The absolute maximum totalizer value is 4.000.000.000
(displayed without the dots). If the max. Value is exceeded the
totalizer will reset to 0 and continues counting from zero again.
No alarm will be generated.
Engineering Time Units
The totalizer can only be started when the engineering units are per
seconds, per minute or per hour. In minutes the totalizer counter runs 60x
faster in case of minutes versus hours and 3600x faster in case of
seconds versus hours. Assuming the full-scale value is identical.
