2.3. 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.
Figure 6: Example display information during the process.

data is kept while the display shows HOLD (flashing).
2. Press HOLD, START, The interrupted batch is resumed.
OR:
Press HOLD, RESET: Stops the batch process at any time, the batch sequence is ended as
a completed batch and the remaining quantity of the batch is ignored.
3. When the batch is stopped and the display shows READY, press RESET for 3 seconds.
You can start a new batch when the display shows 0.
Figure 7: Example display information when interrupted.
▪Power failure during a batch process
When during a batch a power failure occurs, the latest batch information is saved and made
available again at power-up. It is not possible to resume the batch. After the power failure, the
display will show “powerfail”. Before a new batch is possible, the user must confirm the power
failure by pressing the reset-key.
The following information is available on request:
▪Flowrate indication
During batching, the actual flowrate will be displayed after pressing the RATE-key. To return
to the main display: press RATE again or wait for 20 seconds.
▪Display total and accumulated total
When the TOTAL-key is pressed once, the resettable total will be displayed. After pressing
this key again, the accumulated total will be displayed.
The accumulated total cannot be reset. The value will count up to 9,999,999,999. The
measurement unit and the number of decimals are displayed according to the configuration
settings for preset. To return to the main display: press TOTAL again or wait for 20 seconds.
▪Clear total
Total can only be reset if no batch process is active (status: READY).
This function might not be available due to configuration settings.
The value for total can be re-initialized. To do so, select Total and press RESET:
the flashing text "PUSH RESET" will be displayed.
To avoid a reset at this stage, press another key than RESET or
wait for 20 seconds. If RESET is pressed again, TOTAL will be reset to zero.

the functions from the terminals remain available. Note that certain keys on the keypad can be
locked-out with SETUP 9.5 or password protected: read par. 4.2.11.
Read “Terminal 8-11” to lock the batch process.
Terminal 3 to 5, 29 to 32; Flowmeter inputs and supply:
Three basic types of flowmeter signals can be connected to the unit: pulse, active pulse or coil. The
screen of the signal wire must be connected to the common ground terminal.
The input signal type has to be selected with the correct SETUP-function (read par. 4.2.8.).

Sine-wave signal (Coil):
The N410-P can be connected to flowmeters that have a coil output signal. With SETUP 6.1 two
sensitivity levels can be selected:
•COIL LO: sensitivity from about 120mVp-p.
•COIL HI: sensitivity from about 20mVp-p
Figure 13: Terminal connections - Coil signal input (typical)
Reed-switch:
The N410-P is suitable for use with flowmeters which have a reed-switch. To avoid pulse bounce
from the reed-switch, it is advised to select REED LP - low-pass filter (read par. 4.2.8.)

Namur:
The N410-P is suitable for flowmeters with an Namur signal. The N410-P is able to power the Namur
sensor, as an external power supply for the sensor is not required.

Pulse-signal NPN / NPN LP:
The N410-P is suitable for use with sensors which have a NPN output signal. For reliable pulse
detection, the pulse amplitude has to go above 1.2V. Signal setting NPN-LP employs a low-pass
signal noise filter, which limits the maximum input frequency - read par. 4.2.8.
Figure 16: Terminal connections - NPN signal input (typical)
Active signal:
If a sensor gives an active signal (read chapter 3). The detection levels are 50% of the selected
supply voltage; approx. 4V (8-1 DC) or 6V (12 DC) or 12V (24 DC).
Figure 17: Terminal connections - Active signal input (typical)
Pulse-signal PNP / PNP LP:
The N410-P is suitable for use with sensors which have a PNP output signal. For reliable pulse
detection, the pulse amplitude has to go above 1.2V. Signal setting PNP-LP employs a low-pass
signal noise filter, which limits the maximum input frequency - read par. 4.2.8.
A sensor supply voltage of 8.2, 12 or 24V DC can be provided by terminal 29.

Terminal 8 - 9; External control - Start
With this function, the batch controller can be STARTED remotely. The input must be switched with
a potential free contact to the GND-terminal number 8 for at least 100msec.
Figure 19: Terminal connections - External start (typical)
Terminal 8-10; External control - Hold
With this function, the batch process can be interrupted and brought to HOLD status. The input must
be switched with a potential free contact to the GND-terminal number 8 for at least 100msec.
Figure 20: Terminal connections - External hold (typical)
Terminal 8-11; External control - Reset Batch
With this function, the batch process in HOLD status can be cleared remotely with this RESET
function. The input must be switched with a potential free contact to the GND-terminal number 8 for
at least 100msec.
Terminal 11 can also be used to block the batch process: as long as this input is switched to
Terminal 8, it is not possible to start a batch (the START button on the keyboard is blocked as well).
