OPERATIVE MODE

1)Remove the instrument from its case.

2)Set the internal dip switch V101 in closed condi- tion

3)Re-insert the instrument.

4)Switch on the instrument.

DISPLAY FUNCTION

The upper display shows the measured value while the lower display shows the programmed set point value (we define the above condition as “normal display mode”).

NOTE : When the rate of change (Grd1, Grd2) is utilized, the displayed set point value may be different from the operating set point.

It is possible to change the information on the lower display as follows:

-Push FUNC pushbutton for more than 3 seconds but less than 10 seconds.

The lower display will show " r. " followed by

the power value of the OUT programmed as "rEV" control output (from 0.0 to 100.0%*).

-Push FUNC pushbutton again. The lower display will show "d." followed by the power value of the

OUT programmed as "dir" control output (from 0.0 to 100.0%*).

*The graphic symbol " . " means 100%.

-Push FUNC pushbutton again. The display will return in "Normal Display Mode".

NOTE : The two power outputs are displayed only if the relative function has been previously configured.

When no pushbutton is pressed during the time out (see P36), the display will automatically return in "Normal Display Mode".

In order to keep the desired information continuously on the lower display, depress s or

tpush-button to remove the timeout.

When return in "Normal Display Mode" is desired, push FUNC push-button again.

INDICATORS

°C Lit when the process variable is shown in Celsius degrees.

°F Lit when the process variable is shown in Fahrenheit degrees.

SMRT Flashing when the first part of the SMART algorithm is active.

Lit when the second part of the SMART algorithm is active.

OUT1 It will flash with a duty cycle proportional to the linear output value.

OUT2 Lit when OUT 2 is ON or alarm 1 is in the alarm state.

OUT3 Lit when OUT 3 is ON or alarm 2 is in the alarm state

Other functions are shown by decimal points:

REM

SP2

MAN

REM = Flashing, when the instrument is controlled via serial link.

SP2 = Flashing at slow rate when SP2 is used. Flashing at fast rate when a set point from serial link is used.

MAN= Flashing at slow rate, when the instrument is in MANUAL mode.
