[70] od - Delay at power ON
Available:
When at least one output is programmed as
control output.
Range: oFF
Function not used;
0.01... 99.59
hh.mm.
Notes: 1.
This parameter defines the time during which
(after a power ON) the instrument remains in
stand by mode before to start all other function
(control, alarms, program, etc.).
2.
When a program with automatic start at power ON and
od
function are programmed, the instrument performs
od
function before to start the program execution.
3.
When an auto-tune with automatic start at power
ON and od function are programmed, the auto-
tune will start at the end of od delay.
General notes about soft start function.
The soft start function allows to limit the power output for
a programmable time ([72] SSt) or up to a programmed
threshold value ([73] SS.tH) (the first of the two).
When soft start function is running the lower display will
show the message “SSt” alternately to the value selected by
[120] “LdSP” parameter.
[71] St.P - Maximum power output used during
soft start
Available:
When at list one output is programmed as control
output.
Range: -100... +100%
.
Notes: 1.
When St.P parameter have a positive value, the
limit will be applied to the heating output(s) only.
2.
When St.P parameter have a negative value, the
limit will be applied to the cooling output(s) only.
3.
When a program with automatic start at Power
ON and soft start function are programmed,
the instrument performs the soft start and the
program function at the same time.
4.
The auto-tune function will be performed after soft
start function.
5.
The Soft start function is available also when
ON/OFF control is used. In ON condition the
instrument will partialize the output using the
programmed cycle time ([66] tc.H or [68] tc.c).
[72] SSt - Soft start time
Available:
When at list one output is programmed as control
output.
Range: oFF
Function not used;
0.01... 7.59 hh.mm;
inF
Soft start always active (
no “SSt” indication
).
[73] SS.tH - Threshold for soft start disabling
Available:
When at list one output is programmed as control
output.
Range: -1999... 9999
engineering units.
Notes: 1.
When the power limiter has a positive value (the
limit is applied to the heating action) the soft start
function will be aborted when the measured value
is greater or equal to SS.tH parameter.
2.
When the power limiter has a negative value (the
limit is applied to the cooling action) the soft start
function will be aborted when the measured value
is lower or equal to SS.tH parameter.

SP Group - Set Point parameters
The SP group will be available only when at least one output
is programmed as control output (H.rEG or C.rEG).
[74] nSP - Number of used Set Points
Available:
When at least one output is programmed as
control output.
Range: 1... 4
.
Note:
When you change the value of this parameter, the
instrument operates as follows:
•
[81] A.SP parameter will be forced to SP.
•
The instrument verifies that all used Set Point are
within the limits programmed by [75] SPLL and
[76] SPHL. If an SP is out of this range, the instru-
ment forces it to the maximum acceptable value.
[75] SPLL - Minimum Set Point value
Available:
When at least one output is programmed as
control output.
Range:
From
-1999
to
[76] SPHL
engineering units
Notes: 1.
When you change the [75] SPLL value, the inst.ru-
ment checks all local Set Points (SP, SP2, SP3 and
SP4 parameters) and all Set Points of the program
([95] Pr.S1, [100] Pr.S2, [105] Pr.S3, [110 Pr.S4
parameters). If an SP is out of this range, the instru-
ment forces it to the maximum acceptable value
2.
A [77] SPLL change produces the following actions:
•
When [82] SP.rt = SP the remote Set Point is
forced to be equal to the active Set Point.
•
When [82] SP.rt = trim the remote Set Point
is forced to zero.
•
When [82] SP.rt = PErc the remote Set Point
is forced to zero.
[76] SPHL - Maximum Set Point value
Available:
When at least one output is programmed as
control output.
Range:
From
[75] SPLL
to
9999
engineering units.
Note:
For other details see [75] SPLL parameter.
[77] SP - Set Point 1
Available:
When at least one output is programmed as
control output.
Range:
From
[75] SPLL
to
[76] SPHL
engineering units.
[78] SP 2 - Set Point 2
Available:
When at least one output is programmed as con-
trol output and [74] nSP > 2.
Range:
From
[75] SPLL
to
[76] SPH
L engineering units.
[79] SP 3 - Set Point 3
Available:
When at least one output is programmed as con-
trol output and [74] nSP > 3.
Range:
From
[75] SPLL

[76] SPH
L engineering units.
[80] SP 4 - Set Point 4
Available:
When at least one output is programmed as con-
trol output and [74] nSP =4.

From
[75] SPLL

[81] A.SP - Selection of the active Set Point
Available:
When at least one output is programmed as
control output.
Range:
From
SP
to
[74] nSP
.
Notes: 1.
A [81] A.SP change produces the following actions:
•
When [82] SP.rt = SP - the remote Set Point
