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.

3.5 MAINTENANCE REPAIR,AND STORAGE CONDITIONS
UNICONT PDF units do not require maintenance on a regular basis. Repair under or after the guarantee period should only be carried out by NIVELCO.
Unused devices must be stored within the ambient temperature range specified in the technical data, with a maximum of 98% relative humidity.

10 / 24  pdf4012m0600p_06  BKI15ATEX0013X/1
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.
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 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.

5.3 PROGRAMMING
UNICONTs can be programmed by programming keys and the procedure can be followed on the display. HART capable models can also be programmed
remotely via the MultiCONT controller or with the aid of a HART modem and EView2 software installed on a PC. During on site programming remote
programming is not possible and vice versa.
Adjustment of the UNICONT to the conditions of the actual application can be carried out by programming the parameters. If the unit has already been
programmed it is going to work according to the last setting.
The unit will work during programming in accordance with the parameters set previously.
The new, modified parameters will only be effective after returning to Measurement Mode.
If the transmitter is left in Programming Mode by mistake, it automatically returns to Measurement Mode after 3 minutes and is going to operate with the
parameters entered during the last completed programming cycle.
5.3.1. STEPS OF PROGRAMMING
‘Double key pressing’ (pressing two keys simultaneously) has to be used to get into and out of PROGRAMMING mode. It is also used in programming mode.
This is represented in the manual with the symbols of the two keys and the ‘+’ sign in between them. That is:
E
+ (getting into PROGRAMMING mode). This
procedure is should be carried out as follows: press the first key (
E
) and keep it pressed while pressing the key shown after the ‘+’ sign ( ). The two keys
should be kept pressed simultaneously for about 3 s (until the display changes).
After double key pressing of
E
+ the device gets into PROGRAMMING mode and ‘PROG’ symbol is blinking. One of the following two images appears and
parameters can be changed.

When ‘PROG’ is blinking programming can be performed. Since modification of P10 makes the unit restart and reset DEFAULT values it is suggested to begin
programming with checking and / or changing this parameter.
When ‘PROG’ is lit, parameters are being protected by secret code and can only be read out. Applying this code (See P19) provides protection against
unauthorised or unintended parameter modifications.

Remarks:
Double key pressing is indicated by ‘+’
If, after pressing
E
, blinking does not jump over from the parameter address to the parameter value, then this means that
 the parameter is either read-out type, or
 the secret code prevents the modification (see P19)
If the modification of the parameter value is not accepted i.e. the parameter value keeps blinking after pressing ENTER
E
 the modified value is either out of range, or
 the entered code is not valid

5.3.2. PARAMETERS –DESCRIPTION AND PROGRAMMING
Attention! Before programming it is suggested to read the description of parameter P10 carefully!
P0: - - - a Setting input current (Ia) that is to be assigned to displayed value (Da) See Figure 9, 10 and 11 FACTORY DEFAULT: 4 mA
P1: - - - a Setting input current (Ib) to be assigned to displayed value (Db) FACTORY DEFAULT: 20 mA
The current value can be entered in P0 and P1 manually
For instance, entering 5.6 mA in P0 should be performed as shown below:
1. Press
E
+ to get into PROGRAMMING mode
2. Press to go to P0
3. Press
E
to go to the parameter value
4. Press / / to adjust the display to 5.6
5. Press
E
+ to return to MEASUREMENT mode
If the actual current value is to be entered in P0 or P1 it can automatically be set by the GET VALUE function. To do so the above described
procedure should be performed, but pressing +(instead of / / ) (step 4.). Successful setting is indicated by the message ‘SET’
displayed.
Remarks:
If the input current range is set for 4 – 20 mA, than the value of P11 can not be set below 4 mA in P0 and the value of P1 can not exceed 20 mA.
An input current value outside of this range would make VALID LED and current value display blinking.
P2: Setting displayed value (Da) to be assigned to input current Ia See Figure 9, 10 and 11 FACTORY DEFAULT: 0.0
P3: Setting displayed value (Db) to be assigned to input current Ib FACTORY DEFAULT: 100.0
P4: Setting output current pertaining to the input current Ia (for 3-wire models only) FACTORY DEFAULT: 4 mA
P5: Setting output current pertaining to the input current Ib (for 3-wire models only) FACTORY DEFAULT: 20 mA
