OPERATOR INFORMATION AND FUNCTIONS
In general, the N410-P will always function at Operator level. The information displayed and the
functional keys available are dependent upon the SETUP-settings and the active function.
NOTE:
If the key-sign is displayed,
the particular key(s) or functions are not accessible!

To enter a batch quantity
To change the PRESET-value, following procedure must be followed:
1) Press PROG: the word "PROGRAM" will be flashing,
2) Use the numerical keypad 0-9 and decimal position (set with SETUP 1.2 of the
configuration menu) to enter the desired value.
3) Set the new PRESET-value by pressing ENTER.
Figure 5: Example display information during programming preset value.
When data is altered but ENTER has not been pressed, and then the alteration can still be
cancelled by pressing RESET: the former value will be reinstated. The PRESET-value can be
used time after time until a new value is programmed.
Please note that alterations will only be set after ENTER has been pressed!
▪
Batch maximum / minimum
When you program a new value which is not valid - the batch size is too large or too small -
the increase or decrease-sign(e.g.
) will be displayed while you are programming; the new
value will not be accepted but the minimum or maximum allowed value will be set.
▪
Tank fill symbol
The batch process can be visualized with the tank fill symbol. This graphical
representation can be enabled or disabled.
When the batch overfills the preset quantity by 2.5% the graph will show two overspill
arrows indicating this condition.
▪
Starting up the batch process
The batch process can only be started up when "READY" is displayed. The batch process is
started by pressing the START-key. Depending on the SETUP-settings, one or two relays will
be switched. The arrows at the display indicate if the ACTUAL-value will be counting up or
down.
Once the PRESET quantity is reached, the batch outputs will be switched off and the batch
process is ended. A next batch can be started with the same PRESET quantity or a new value
can be entered.
The N410-P is equipped with a smart
– self learning – overrun correction: at the end of the
process, the outputs will be switched-off earlier as the PRESET value, taking the overrun
quantity of previous batches into account. The result is an accurate batch, even in slowly
varying circumstances. During overrun, a clock will be displayed and R1 / R2 will be flashing.
