ment was in manual mode, the instrument will not
modify the valve position.

3 =

It starts in the same way it was prior to the power
shut down.
o If: - the time proportioning output is configured

- the instrument was in manual mode

the power output will be set equal to the last value
prior to power shut down.
o If: - servomotor control is configured

- the instrument was in manual mode
- P40 = "bUnP"

the instrument will not modify the valve position.
o If: - servomotor control is configured

- the instrument was in manual mode
- P40 is different from "bUñP"

the instrument will modify the valve position in order
to reach the value set in P40.

P40 = Transfer from AUTO to MANUAL
This parameter is skipped if P38 = OFF
When P5 = "Sñ.OL" and P6 = "no.Fb", this parameter is
forced to "bUñP" and it cannot be modified.
-

When the device is configured for one control output,
P40 can be set from 0 to 100

-

When device is configured for two control outputs, P40
can be set from -100 to 100.

Above the 100 value the instrument will show "bUñP" and
the transfer will be bumpless (the manual mode starts
with an output value equal to the last value in the auto
mode)
NOTE: If P40 is different from "bUñP" and an open loop
servomotor control with feedback potentiometer is
programmed, the instrument will reach the P40 value
using the feedback indication.

P41 = Conditions for output safety value
When P5 is different from "Sñ.OL" the P41 possible
selections are:
0 = No safety value ("Standard" effect)
1 =

Safety value applied when overrange or underrange
condition is detected.

2 =

Safety value applied when overrange condition is
detected.

3 =

Safety value applied when underrange condition is
detected.

P34 =

Maximum value of the proportional band calcu-
lated by the SMART algorithm.

This parameter is skipped if P33=0.
It is programmable from P35 value to 200.0 %.

P35 =

Minimum value of the proportional band calcu-
lated by the SMART algorithm

This parameter is skipped if P33=0.
It is programmable from 1.0 % to P34 value.

P36 =

Minimum value of the integral time calculated
by the SMART algorithm.

This parameter is skipped if P33=0.
It is programmable from 1 second (00.01) to 2 minutes
(02.00).

P37 =

Relative cooling gain calculated by SMART
function.

This parameter available only when device is configured
with two control output and P33 is different from 0.
OFF =

SMART algorithm does not calculate the rC
parameter value

On =

SMART algorithm calculates the rC parameter
value.

P38 = MANUAL function

OFF =

manual function is disabled

On =

manual function can be enabled/disabled by
MAN pushbutton or by contact closure on
logic input 2.

P39 =

Device status at instrument start up.

This parameter is skipped when P38 = OFF.
0 =

the instrument starts in AUTO mode.

1 =

the instrument starts in manual mode.
o If the time proportioning output is configured, the
power output will be set to 0.
o If servomotor control is configured, the
instrument will not modify the valve position.

2 =

It starts in the same way it was prior to the power
shut down.
o If the time proportioning output is configured and

the instrument was in manual mode, the power
output will be set to 0.

o If servomotor control is configured and the instru-
