The upper display shows the process variable and PRG
indicator is lit.
The instrument can be in AUTO mode or in MANUAL mode.
When the instrument is in MANUAL mode, the upper display
shows the measured value, the middle display shows "ñ."
followed by the main power output value and the lower display
shows "S." followed by the secondary power output value (for
more details see the "MANUAL MODE" paragraph) and PRG
and MAN indicators are lit.
When the instrument is in AUTO mode, the upper display shows
the measured value, the middle display shows the operative set
point, the lower display shows the main power output on the two
MSD and the secondary power output on the two LSD; the
decimal point between the two indications is flashing.
By pushing the FUNC pushbutton it is possible to select the
same indications described at point e, f, g, h, i, l, m and n of the
previous paragraph.
OUTPUT POWER OFF FUNCTION during programmer mode
By this mode it is possible to disable the process control.
In this mode, the instrument operate as an indicator and:
- the middle display shows O.P.O.;
- the lower display and the bargraphs are void;
- the time proportional control outputs are set to zero;
- the linear control outputs are set to the initial scale value;
- the servomotor output maintain the same position has prior to
the power output mode.
- all alarm are in “NO alarm condition”;
- all the events not related with the end of program or with the
Output Power OFF mode are in OFF condition;
- all the logic input status (exception made for RUN/Hold input)
are ignored;
- all the analog retransmissions are forced to the initial scale
value.
It is possible to program a digital output in order to signal when
the instrument is in OPO mode.
When the instrument is turned off in OPO mode, at power up it

Exiting from O.P.O. mode, the instrument operate as in presence
of a power on condition and the alarm masking and the soft start
