Thank you for choosing NIVELCO instrument
We are sure that you will be satisfied throughout its use!
1. INTRODUCTION
The UNICONT PDF-01 and PDF-01-6/A/C Ex devices are 2-wire on-site indicators that can be inserted into a 4 … 20 mA current loop without the need for
additional power supply. Since the displayed value is proportional to the input, the units are suitable for indication of temperature, pressure, level, etc. values,
the information carried by the loop current. The customer can program the engineering units and the indication range.
The HART capable UNICONT PF-01-4 and PF-01-8/B/D Ex 3-wire process indicators require additional power supply. Besides displaying the loop
current or the process values, these units convert input current to HART signals and so enable devices that have analogue outputs only to be integrated into
HART multidrop systems. The ratio between the input and output current can be programmed.
The intelligent electronics and HART communication enables versatile signal processing and remote programming. The software uses the Universal HART
commands No. 1-3, 6, 7, 11-18 and device specific commands No128-132, 135 and 139 of the HART Revision 5.
Robust enclosure makes applications under harsh conditions also possible. Explosion proof versions are available for hazardous environments.

4. INSTALLATION AND ELECTRIC CONNECTION
The devices are suitable for working in closed area or they can be used in open-air applications. When choosing the installation place please ensure proper
space for the mounting, programming and checking the display. Mounting the units on the wall or to a support can be done with using 2 pcs of M4 nuts. To avoid
overheating the instrument should be protected against direct sunshine.

BKI15ATEX0013X/1 ♦pdf4012a0600p_06 ♦7 / 20
4.1 WIRING
• 2-wire indicators are used in 4–20 mA current loops. They do not require external power supply.
• 3-wire devices are powered with 10 V…36 V DC (Ex type devices: 10 V...30 V DC) through the output.
• Make sure, that current values on the internal terminals should not exceed overload capability limits.
• Wiring should be done with shielded cable, specified under ‘Technical Data’ table.
• Devices should be grounded by using their grounding screws.
• The screw terminals can be accessed after removal of the housing cover and the display module.
• After wiring and programming the cover should be screwed to tightness of the sealing.
!
The types with stainless steel housing are not allowed to be set up and installed until,
the „Ex d” certified cable gland is not fixed to the place of the red plastic closing cap with proper sealing!
The metal plug may only be removed if 2 cable glands are used.
!
The housing cover of the flameproof device is allowed to remove only when the unit is de-energized!
The housing cover can be removed after unscrew the M2 size hex socket set screw
or after dismounting the safety locking bolt by unscrew the M4 size hex socket set screws.
!
The instrument may be damaged by electrostatic discharge (ESD) via its terminal, thus apply the precautions commonly used to avoid
electrostatic discharge e.g. by touching a properly grounded point before removing the cover of the enclosure.
A possible electrostatic discharge can cause damage for the instrument. Do not touch the internal terminals!
!
After wiring and programming the housing cover should be closed properly and the hex socket set screw or the safety locking bolt should be
tightened! The sealing ring must be replaced if damaged, otherwise the IP class of the device can be jeopardized.

4.2 SAFETY REGULATIONS FOR THE EX CERTIFIED UNITS
– WARNING! DO NOT OPEN WHILE ENERGIZED!
– Devices should be grounded by connecting their grounding screws to the equipotential system.
– Intrinsically safe units with Ex ia IIC, Ex ia IIB or Ex d+ia IIB markings can only be used in certified intrinsically safe loops with the previously given
technical data.
– The aluminium content of equipment with metallic enclosure exceeds the limit, the devices must be protected against impact and friction effects.
– The size of the macrolon window of intrinsical safe equipment with metallic enclosure exceeds the limit, thus the devices must be protected against
electrostatic charges.
– Equipment with plastic housing are susceptible to electrostatic charges, thus the devices must be protected against electrostatic charges.
– The units with stainless steel housing (with Ex d or Ex d+ia protection type) are allowed to be operated only with using properly sealed „Ex d” certified
cable gland.
5. PUTTING INTO OPERATION, PROGRAMMING
Lighting of the VALID LED indicates that the Unicont, installed and wired
correctly, will operate according to the Manufacturer’s settings (see 5.1. Default).
The device operates in MEASUREMENT mode. It is indicated by the format of
the displayed value and that the PROG display is not lit.
