NIVELCO UNICONT PMM-300 User manual

Thank you for choosing a NIVELCO instrument.
We are sure that you will be satisfied throughout its use.
1. APPLICATION
The UNICONT PMM-300 series is a universal display and controller. It can also be used as (one
or two channel) display and limit-switch depending on the configuration of the instrument. For the
complete range of the models, technical data and programming in detail see the INSTALLATION
AND PROGRAMMING MANUAL.
The aim of this User’s Manual is to give a concise guideline for applications of the UNICONT
PMM as a process display and limit switch.

You can change over from one Factory Default to another one by
disconnecting the instrument first. Push the three buttons simultaneously
and at the same time reconnect it again to the main.
Note:
By changing over from one Default Program to another will represent
reset of the programming performed by the customer i.e. it will result in
return to the parameters and settings of the Factory Defaults.

8. UNICONT PMM AS ONE-CHANNEL DISPLAY AND
LIMIT-SWITCH
8.1 SETTING FACTORY DEFAULT AND PROGRAMMING
The instrument will be delivered with Factory Default A. The active
Factory Default can be changed over by triple push-button operation and
checked in the Submenu point C.in1 (if you can be sure that the Factory
Default settings and parameters prevail).
C.in.1 Factory Default
xxx01110 “A” – Process control oriented
xxx11010 “B” – Process indicator with limit switch (4-20 mA input)
Note: “X” means that the position of EDS is irrelevant concerning Factory Default.
PARAMETERS OF FACTORY DEFAULT B:
Denomination Function/Value EDS/Parameter
Input
Position of the decimal point 4-20mA 999.9 C.in1 : 00111010
Scaling 4mA=0,0%
20mA=100,0% C.i1L : 0.0 C.i1H : 100.0
Operation mode Display, 1 input d.Cnt : 00000001
AL1 alarm relay operation Energised under the
lower alarm value d.AL1 : 00000001
AL1 energised over the min value 10% S.A1 : 10.0
AL2 alarm relay operation Energised over the
upper alarm value d.AL2 : 10000001
AL2 energised over the min value 90% S.A2 = 90.0
Current output 4-20mA proportional
to the current input C.out : 00001000
Output value assigned to the
minimum input value 0% C.o1L : 0.0 *
Output value assigned to the
maximum input value 100% C.o1H : 100.0 *
Operation of the buzzer in line with AL2 d.HSt : 01010000
Filtering of the input signal medium C.FLt : 00110000
*This setting means that with input 4-20 mA the output will also be 4-20 mA,
practically the input will be “retransmitted”.
8.2 CHANGING PARAMETERS OF FACTORY DEFAULT:
- Set % value of energising relay AL1 at Submenu point S.A1
- Set % value of energising relay AL2 at Submenu point S.A2
-SETTING HYSTERESIS OF RELAY AL1
Set position of hysteresis (e.g. control of filling) at Submenu point d.AHS:
(default parameter: 00000001)
Set value of hysteresis at Submenu point d.A1h e.g. 5%, d.A1h=5.0
- SETTING HYSTERESIS OF RELAY AL2
Set position of hysteresis (e.g. control of emptying) at Submenu point
d.AHS: (default parameter: 00000000)
Set value of hysteresis at Submenu point d.A2h e.g. 5%, d.A2h=5.0
- SETTING BUZZER:
At Submenu point d-HSt. (default setting:00000000, out of work)
8.3 SCALING
Assign values (e.g. level in meter or % to be displayed) to the input
signals
- Assign minimum value to the minimum input signal at C.i1L
- Assign maximum value to the maximum input signal at C.i1H
The displayed value will be proportional to the input signal.
For example: Input signal min: 4 mA C.i1L=100.0
Input signal max: 20 mA C.i1H=900.0
Is the input signal IN1=12 mA, the value of 500.0 will be displayed.
Note: Should the scaling be changed, the energising values of the ALARM
relays have to be modified.
8.4 LINEARISATION
Linearisation will be needed if the relation between the measured value
and the displayed value is not linear. This non-linear function can be
approached by a series of data-pairs. This makes possible for example
to display the volume of the medium in a horizontal cylindrical tank by
measuring the level. The UNICONT PM-33_ and the PM-34_ can
perform a linearisation of 32 data-pairs.
Steps of linearisation:
- The analogue signal arriving on IN1 has to be scaled. (See point 8.3)
- The enabling of linearisation and the modifiable analogue signal will be
set at Submenu point C.uSr.
- After setting C.uSr the data-pairs are to be entered at the Submenu
points I.t01 and O.t01.
The measured values and values to be displayed have to be entered at
Submenu points I.txx (in the measurement units of the input) and
Submenu points O.txx (in the measurement units of the output)
respectively. For example should the value at the Submenu point It01
be 15 and the value at the Submenu point O.t01 be 18, that means that
with the input signal reaching 15 the value of 18 will be displayed. The
32 point-pairs can be entered in optional order with the constraint that
increasing values of I.txx should come with increasing values of O.txx.
9. UNICONT PMM-300 AS TWO-CHANNEL DISPLAY
AND LIMIT-SWITCH
The UNICONT PMM-32_ and PMM-34_ are configured for applications
with two-channel display and limit-switch.
9.1 PROGRAMMING:
To programme the second channel you have to take the same steps as
described under 8.2. The setting of the decimal point will also be valid for
the second channel. (See below the steps with parameters of the
Factory Default B.)
- Selection of the input signal IN2 (4-20mA): C.in2: 00011010
- Scaling of the input signal IN2 4mA C.i2L: 0.0%
20mA C.i2H: 100.0%
- Display IN2 input signal in the bottom row set at d.Cnt: 00010001
- Alarm relay operation AL3: energised under the lower limit of IN2 set at
d.AL3: 10000011
- Set energising value of relay AL3 (10%) at Submenu point S.A3:10.0
- Alarm relay operation AL4 energised above the upper limit of IN2, set at
d.AL4: 10000011
- set energising value of relay AL4 (90%) at Submenu point S.A4:90.0
9.2 ARITHMETIC FUNCTION
Take following steps to make use of differential function
-Scale display of input signals IN1 and IN2.
-The enabling and the selection of the arithmetic function (difference,
summarise or average) will be set at submenu point C.nAt.

10001xxx Providing average PV=(IN1+IN2) / 2
Note: “X” means that the position of EDS is irrelevant concerning the arithmetic
functions.
9.3 ROUNDING:
Rounding may be necessary in applications where due to the technology
process the last digit displayed is fluctuating (waves on the surface of the
liquid) that has to be eliminated. Rounding, set by the last three digits of
the submenu point C.nAt will be performed according to the general rules
of the rounding.

11. DISABLING FUNCTIONS
The modifications of some parameters can be disabled by the use of an
access code or at the Submenu point d.nni or by push-buttons on the
front panel.
a, Disabling by access code
Modifications of the Submenu points under the Definition Table and the
Calibration Table can be disabled by the access code (the Submenu
points under the Parameter Table and the Standard Table can be
accessed).
There is no access code given in the Factory Default. In the Submenu
Point d.Pas (displaying 0) any four-digit access code chosen between
0001 and 8091 can be entered. Instruments with access code will display
at d.Pas the number of 9999. After entering the correct access code it
can be overwritten (giving either a new four-digit number or 0000 for
erasing the access code).
Note: In case of access code forgotten or lost, make use of the general
reset by repeated Triple Push-Button operation.
b, Disabling at Submenu point d.nni:
EDS Description Remark
xxxxxxx1 Alarm relays disabled
xxxx0xxx Display values settable by digits
(spinning wheel)
xxxx1xxx Display values settable in sequence
(by scrolling) Factory Default
xxxxx1xx After power supply failure the instrument
will be switched out with Er5.
c, Disabling by push-button (See Double Push-Button Operation)
Disabling access to the Menupoint Definition (table) by simultaneous
pressing of the push-buttons and
PE
over 25 sec. Repeated Double
Push-Button operation will release disabling.
12. ERROR MESSAGES
In case of entering incorrect values or operation failure an error code will
be displayed on the SV display.
