1. INTRODUCTION
The UNICONT PDF-4/501 and PDF-401-6/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-4/501-4 and PF-401/8/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 areas or they can be used in open-air applications, too. Installation location should be selected so that proper
space is available for handling, programming and checking the display. Mounting the units on the wall or to a support can be done with using 2pcs of M4 nuts.
4.1 WIRING
•2-wire indicators are used in 4… 20 mA current loops. They do not require separate power supply.
•3-wire devices are powered with 10…36 VDC through the output.
•Current values on the terminals should not exceed overload capability limits. *
•Wiring should be made with shielded cable, specified under ‘Technical Data’.
•After removal of the cover of the housing and the display module the screw terminals can be accessed. ** Cover of the flame proof housing can be
removed after unhooking the safety clamp. Device should not be under power.
•After wiring and programming the cover should be screwed to tightness of the sealing. The safety clamp of the flameproof cover should be fastened.
*Max. 150 mA for 2-wire and max. 200 mA for 3-wires devices.
** Devices should be grounded by using their grounding screws.
!
The unit may be damaged by electrostatic discharge (EDS) at its terminal, thus the precautions commonly used to avoid
electrostatic discharge e.g. by touching a properly grounded point before removing the cover of the enclosure should be applied.
