Thank you for choosing a NIVELCO instrument.
We are sure that you will be satisfied throughout its use!
1. GENERAL DESCRIPTION
The UNICONT PMM-500 universal display and controller instruments are 1/16 DIN (48x48mm) size, panel
mountable, modern, easy of use microprocessor based devices supporting versatile functions. EEPROM
memory ensures data- and program protection during power outages.
The universal input can be connected with wide range of temperature sensors (Pt-100 RTD-s and most type
of thermocouples), or standard analogue current and voltage signals (mA, mV, V).
The instrument operates its control outputs in accordance to selected control algorithm generated from the
measured input values of various physical parameters.
The control algorithm can be ON-OFF, or PID, therefore it can provide differential control, or can realize
multiple control characteristics.
Using the Auto Tuning mode, the instrument provides optimal settings without entering any P-I-D
parameters.
The controller has multiple outputs: relay, SSR-driver, analogue current-, or voltage output, RS485
communication. The modular structure provides wide selection of output variations. In accordance to the
mechanical structure of the output boards (plug-in PCB-s) there is a possibility to order special (differing
from the standard) variations.

The RS485 Modbus RTU serial output provides digital communication interface with PC and remote
programming possibility.
Some models have 24V DC output performing power supply for transmitters.
The large bi-coloured 2-line, 7-segmented, 4-digit LED display provides easy reading even from far distance.
It indicates the Process (PV) and a Set-point (SV) Value, as well the programming steps or other settings.
Operation modes and alarm signals are indicated with LED-s. The 4 push-buttons provide easy
programming.

4. DIMENSIONS
The unit can be mounted into a
suitable 1/16DIN (48x48 mm) cut-
out place. Insertion length of the
unit is 110mm, the additional
dimensions can be seen on the
drawing below.

5. MOUNTING
The unit can be mounted with the help of the
attached mounting accessory to the suitable cut-out
hole. Be careful with the sealing, which provides
proper sealing from the front panel. Suitable
distances between multiple units should be taken
into consideration.
The cut-out dimensions in case of single, or multiple
units should be the following, and width of the
mounting-plate is Lv=3-9 mm.
Using the optional PAM-500-0 front plate size
adapter the 48x48mm sized unit can be mounted to
an existing 96x48mm cut-out hole. In case of using
the front plate size adapter, the width of the
mounting-plate is Lv=3-5 mm

Notes:
Connect the line voltage (live and neutral) as illustrated via a
two-pole isolating switch (preferably located near the equipment)
and an anti-surge fuse.
All analogue and communication signals must use shielded
cable. The shield should be grounded at one end only.
Two wire RTDs leads should be less than 3 metres long,
resistive leg and the common legs of the RTD (4-5 points) should
be connected.
Four wire RTDs can be used, provided that the fourth wire is left
unconnected.

After powering ON the unit performs an automatic self-test and flashes all front-plate LEDs for a moment. At
first turning ON, or after replacing an output module indication can be seen on the

Loop Alarm
A loop alarm is a special alarm, which detects faults in
the control feedback loop, by continuously monitoring
process variable response to the control output(s). The
loop alarm can be tied to any suitable output. When
enabled, the loop alarm repeatedly checks if the control
output(s) are at the maximum or minimum limit. If an
output is at the limit, an internal timer is started:
thereafter, if the high output has not caused the process
variable to be corrected by a predetermined amount 'V'
after time 'T' has elapsed, the loop alarm becomes
active. Subsequently, the loop alarm mode repeatedly
checks the process variable and the control output(s).
When the process variable starts to change value in the
correct sense or when the output is no longer at the limit,
the loop alarm is deactivated. For PID control, the loop
alarm time 'T' is always twice the Automatic Reset
parameter value. For On-Off control, a user defined
value for the Loop Alarm Time parameter is used. The
value of 'V' is dependent upon the input type. For
Temperature inputs, V = 2°C or 3°F. For Linear inputs, V
= 10 least significant display units.
Control output limits are:
0% for Single output (Primary only)
controllers
-100% for Dual output (Primary and
Secondary) controllers
Correct operation of the loop alarm depends upon
reasonably accurate PID tuning. The loop alarm is
automatically disabled during manual control mode and
during execution of the Pre-Tune mode. Upon exit from
manual mode or after completion of the Pre-Tune
routine, the loop alarm is automatically re-enabled.
