Operation Manual Flow Transmitter DW-D
4.5 Adjusting of integration time
The DW-D Flow transmitter makes 18870 measurements pro minute. If the result of each
measurement would be shown on the display, the indication would change it’s worth
continuously and it would be very difficult to read off the indication. Therefore it is possible to
program a integration time between 0 and 3,4s. Then the average value of the values
measured within the programmed time is shown. A long integration time causes a slowly
changing indication which is easy to read. We recommend to maintain the standard
adjustment of 1s. For changing the integration time you can choose the wished time with help
of the buttons
and
in menu
INT.[s]
Button P takes over the adjustment.
4.6 The totalizer
The device is equipped by a totalizer, which adds the flow quantity. (Menu point
TOT: X
.) X
corresponds to the respective quantity. The unity results from flow unity. (for example l/min
corresponds to l). Actuating button
push down the memory to zero.
PRESS
+
to reset
appears (+ =
). Now actuate
as long as the appearing counter is
executed (20s).
In case of power failure or too low current the actual amount will be ensured. If necessary
voltage is back again the device notifies
POWER LOW / PRESS P &
respectively
PRESS P
&
. Pressing P and
(at same time) DW-D changes back to standard modus. After that the
device starts counting from the amount has been present at the time of power failure. This
guarantees that the operator is aware of that power supply was interrupted and so the amount
indicated perhaps not corresponds to the real quantity.
Attention:
The power failure supervising function only works if at menu point
BATT CHECK
(see 4.1) the function is activated
(ON)
The device has a 8 digit display so a big capacity is available. Nevertheless depending on
unity, flow quantity and time of flow the capacity may be quite different. If the max. indication
value is reached, DW-D starts with zero again. At the totalizer menu you see the actual value
in the moment of switch over to the totalizer function. That means always when the totalizer
menu is actuated the indication is updated.
The actual value only is indicated if the totalizer is defined as standard indication
4.7 Restriction of access by code number
In order to restrict of access of not authorizes persons to the programmed dates it is possible
to activate a code number. In the point of menu
PIN [+/-]
it is possible to adjust any code
number between 1 and 999 by help of the buttons
and
. By pressing P and
at the same
time the programmed code number is activated.
ENABLE
is appearing
.
If an adjustment in
any menu now should be changed the operator is asked for the code number. The number
can be entered liked described above. After that
PIN OK!
is appearing
.
Now the adjustment
can be changed. If
PIN NOT OK!
is appearing input was wrong. You now can repeat entering
the code number.
Attention:
Should the number be forgotten the adjustments can not be changed any more. At
point of menu
PIN [+/-]
restriction of access can be
switched off. Therefore code number has
to be entered as described above.
PIN OK!
And thereafter
DISABLE
is appearing
.
