The "Soft start" function allows to limit the maximum
output power (see OLH operative parameter) for a
programmable time (see tOL operative parameter)
at the instrument start up when the measured value
is lower then the programmable threshold.
Insert the threshold value, in eng. unit.
P11 = Safety lock P11 = Safety lock P11 = Safety lock P11 = Safety lock P11 = Safety lock
0 = device unlocked. All the parameters can be
modified
1 = device locked. No one of the parameters can
be modified except the SP.
2 to 499 = Select the secret code (to be
remembered) and during the "operative during the "operative during the "operative during the "operative during the "operative
mode" mode" mode" mode" mode" and scrolling the "software key"
parameter, the display will show one of the
following figures:
A) The device is "Unlocked"
and all parameters can be
modified.
To make the device
O F F O F F O F F O F F O F F
"Locked" insert a number
different from the "secret
n n n n n n n n n n n n n n n
code". Now no one of the
parameters can be modified
except the SP.

one of the parameters can be
modified except the SP.

To "Unlock" the device,
insert the "secret code".
500 to 999 = Selecting a secret code between these
two numbers, every thing will occur as ex-
plained above except that when the device is
"Locked" the parameters that can be modified
are the set point and the alarm threshold.
P12 = output maximum rate of rise P12 = output maximum rate of rise P12 = output maximum rate of rise P12 = output maximum rate of rise P12 = output maximum rate of rise
This parameter is available only if Pb is different
from 0.
It is programmable from 1 to 10 % of the output
signal per second.
Setting a value greater then 10%/s the instrument
shows "InF" and no ramp limitation is applied.

For RTD input with decimal figure, P13 is is
programmable from 0.2 to 20.0 °C.
For all the other inputs, it is programmable from 2
to 200 engineering units.
The configuration procedure is completed and the
instrument shows " -.-.-.-. " on both displays.
When it is desired to end the configuration
procedure push the FN pushbutton; the display
will show "COnF".
When it is desired to access to the advanced
configuration parameter procede as follows:
1) using and pushbutton set the 219 code.
2) push the FN pushbutton.
