1. APPLICATION AND METER DESIGN
The programmable digital panel meter N30O is destined for measu-
rements: number of pulses, frequency, period, worktime, encoder
position. Additionally, the meter enables the indication of the current
time. The readout field is a LED display, which allows the exposition
in colours: red, green and orange. The measured input signal can be
arbitrary converted by means of mathematic functions and/or a 21-point
individual characteristic.
Features of the N30O Meter:
ldisplay colour individually programmed in three ranges,
lprogrammable thresholds of displayed overflows,
l2 NOC relay alarms operating in 6 modes,
l2 switched relay alarms with a switching contact operating
in 6 modes (option),
lsignaling of measuring range overflow,
lautomatic setting of the decimal point,
lprogramming of alarms and analog outputs with the reaction
on the selected input quantity (main or auxiliary input),
ladditional counter input,
lcontrol inputs of the main input work, additional or both simultaneously,
lsignaling of additional input state,
lpossible control of counter operation by means of the meter keyboard,
lautomatic reset of counters at the set point value
lreal-time clock with the function of the clock supply support in case
of the meter supply decay,
lprogrammed averaging time – function of walking window with the

4. INSTALLATION
The meter has separable strips with screw terminals, what enables the
connection of external wires of 1.5 mm2cross-section for input signals
and 2.5 mm2for other signals.
One must prepare a hole of 92+0,6 ´45+0,6 mm in the panel, which the
thickness should not exceed 6 mm.
The meter must be introduced from the panel front with disconnected
supply voltage. Before the insertion into the panel, one must check the
correct placement of the seal. After the insertion into the hole, fix the
meter by means of clamps (fig. 2).

4.2. Examples of Connections
An example of a N30O meter and a inductive sensor connection with
an output of NPN and PNP type is presented on the fig. 5. The way to
connect a transducer with an output of contactron/relay type is pre-
sented on the fig. 6. In examples, the connection of the main input W1
is shown. Other inputs are connected in the same way but we must
remember, that all inputs are galvanically separated between them and
have a system limiting the input current. The range of voltages control-
ling the input should be in the 5..24 V d.c. range.

5.2. Messages after Switching the Supply on
After switching the supply on, the meter displays the meter name N30O
and next, the program version in the shape „ x.xx” – where x.xx is the
number of the current program version or the number of a custom-
made option. Next, the meter carries out measurements and displays
the value of the input signal. The meter sets up automatically the de-
cimal point position when displaying the value. The format (number of
places after the decimal point) can be limited by the user.
5.3. Functions of Buttons
- Acceptation button:
Þentry in programming mode (press and hold down ca 3 seconds),
has not gone by

13
Þmoving through the menu – choice of level,
Þentry in the mode changing the parameter value,
Þacceptation of the changed parameter value,
Þstop the measurement – when holding down the button, the result
on the display is not updated.
The measurement is still carried out.
- button increasing the value:
Þdisplay of maximal value, The pressure of the button causes the
display of the maximal value during ca 3 seconds,
Þentry in the level of the parameter group,
Þmoving through the selected level,
Þchange of the selected parameter value – increasing the value.
- button changing the digit:
Þdisplay of minimal value, The pressure of the button causes the
display of the minimal value during ca 3 seconds,
Þentry in the level of parameter group,
Þmoving through the selected level,
Þchange of selected parameter value – shift on the next digit,
- resignation button:
Þentry in the menu monitoring the meter parameters (by holding
down ca 3 seconds),
Þexit from the menu monitoring meter parameters,
Þresignation of the parameter change,
Þabsolute exit from the programming mode (holding down
ca 3 seconds).
The pressure of the button combination and holding
them down ca 3 seconds causes the erasing of alarm signaling. This
operation acts only when the support function is switched on.
The pressure of the button combination causes the era-

5.4. Programming
The pressure of the button and holding it down through ca 3
seconds causes the entry in the programming matrix. If the entry is pro-
tected by a password, then the safety code symbol SEC is displayed
alternately with the set up value 0. The write of the correct code causes
sing of the minimal value.
The pressure of the button combination causes the era-
sing of the maximal value.
The pressure of the button combination causes the display
of the second counter contents. A longer holding down (longer
than 3 seconds) causes the reset of the main counter (if the ser-
vice of counters from the keyboard is switched on). The auxiliary
counter is reset only from the Inp2 counter.
The pressure of the button combination longer than
3 seconds causes counting stop (for pulse counter and work time coun-
ter mode), in case when the button function is on.
The pressure of the button combination longer than
3 seconds causes count start (for pulse counter and work time counter
mode), in case when the button function is on.
The pressure and holding down the button during 3 seconds
causes the entry to the programming matrix. The programming matrix
can be proteced wit security code.
The pressure and holding down the button during 3 seconds
causes the entry to the menu monitoring meter parameters . One must
move through the monitoring menu by means of and
buttons. In this menu, all programmable meter parameters are only ava-
ilable for readout. In this mode, the menu Ser is not available. The exit
from the monitoring menu is carried out by means of the button.
In the monitoring menu, parameter symbols are displayed alternately
with their values.
The service algorithm of the meter is presented on the fig. 8.

5.4.1. Value Change Way of the Chosen Parameter
In order to increase the value of the selected parameter, one must
press the button. A single pressure of the button, causes the
increase of the value of 1. The increase of value when displaying the di-
git 9 causes the setting of 0 on this digit. The change of the digit follows
after pressing the button.
In order to accept the set up parameter, one must hold down the
button. Then, the write of the parameter and the display of its symbol
follows alternately with the new value. The pressure of the but-
ton during the change of the parameter value will cause the resignation
of the write.
5.4.2. Changing Floating-Point Values
The change is carried out in two stages (the transition to the next stage
follows after pressing the button):
1) setting the value from the range -19999...99999, similarly as for in-
tegral values;
the entry in the matrix, the write of an incorrect code causes the display
of the ErCod symbol. The matrix of transitions into the programming
mode is presented on the fig. 9. The selection of the level is made by
means of the button, however the entry and moving through
the parameters of the chosen level is carried out by means of
and buttons. Parameter symbols are displayed alternately with
their current values. In order to change the value of the selected pa-
rameter, one must use the button. To resign from the change,
one must use the button. In order to exit from the selected le-
vel, one must chose the ----- symbol and press the button. To
exit from the programming matrix, one must press the -button
during ca 1 second. Then, the inscription End appears for ca 3 se-
conds and the meter displays the measured value. In case of leaving
the meter in the parameter programming mode, the automatic aban-
don of the programming mode parameter (parameter, next the menu)
follows after 30 seconds and the meter displays the measured value.

19
2) setting of the decimal point position (00000., 0000.0, 000.00, 00.000,
0.0000); the button shifts the decimal point to the left, howe-
ver the button shifts the decimal point to the right;
The pressure of the button during the change of the parameter
value will cause the resignation of the write.
