P34 = Maximum value of the proportional band
calculated 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
calculated 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 .
O = 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
instrument was in manual mode, the instru-
ment 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 = "bUmp"
the instrument will not modify the valve
position.
o If: - servomotor control is configured
- the instrument was in manual mode
- P40 is different from "bUmp"
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 = "smOL" and P6 = "no.fb", this
parameter is forced to "bUmp" 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
"bUmp" and the transfer will be bumpless (the
