ROGRAMMING
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.

TEPS 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.

:
xxxxx
y one-digit parameter address ( 0, 1 , … 9 )

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.
