[68] 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 od
function will be aborted and auto-tune starts
immediately.
[69] St.P - Maximum power output used during
soft start
Available:
When at least 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 both the functions at the
same time. In other words, the program performs
the first ramp, if the power calculated by PID is
lower than the programmed limit, the instrument
operates with the requested power.
When the PID requires a power higher than the
limit, the instrument will limit the power to the one
programmed.
4.
The auto-tune function inhibits the soft start
function.
5.
The Soft start function is available also when
ON/OFF control is used.
[70] SSt - Soft start time
Available:
When at least one output is programmed as
control output.
Range:
oFF = Function not used;
0.01... 7.59 hh.mm;
inF =
Soft-start always active.
[71] SS.tH - Threshold for soft start disabling
Available:
When at least one output is programmed as
control output.
Range:
-1999... 9999 engineering units.
Notes: 1.
When the power limiter have a positive value (the
limit is applied to the heating action) the soft start
function will be aborted when the measured value
is greater than or equal to SS.tH parameter.
2.
When the power limiter have a negative value
(the limit is applied to the cooling action) the soft
start function will be aborted when the measured
value is lower than 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).
[72] nSP - Number of used set points
Available:
When at least one output is programmed as
control output.
Range:
1... 4.
Note:
Changing [72] nSp value the instrument operates as
follows:
•
[79] SPAt parameter will be forced to SP1.
•
The instrument verifies that all used set points are
within the limits programmed by [73] SPLL and
[74] SPHL.
•
If an SP is out of this range, the instrument forces its
value to the maximum acceptable value.
[73] SPLL - Minimum set point value
Available:
When at least one output is programmed as
control output.
Range:
From -1999 to [74] SPHL in engineering units.
Notes: 1.
Changing [73] SPLL value, the instrument checks
all local set points (parameters: SP1, SP2, SP3
and SP4) and all program set points (parameters:
[94] Pr.S1, [99] Pr.S2, [104] Pr.S3, [109] Pr.S4).
If an SP is out of this range, the instrument forces
its value to the maximum acceptable value.
2.
A [73] SPLL change produces the following actions:
•
When [80] SP.rt = SP, the remote set point will
be forced to be equal to the active set point;
•
When [80] SP.rt = trim, the remote set point
will be forced to zero;
•
When [80] SP.rt = PErc, the remote set point
will be forced to zero.
[74] SPHL - Maximum set point value
Available:
When at least one output is programmed as
control output.
Range:
From [73] SPLL to 9999 (E.U.).
Note:
For other details see [73] SPLL parameter.
[75] SP 1 - Set Point 1
Available:
When at least one output is programmed as
control output.
Range:
From [73] SPLL to [74] SPHL (E.U.).
[76] SP 2 - Set Point 2
Available:
When at least one output is programmed as con-
trol output and [72] nSP > 1.
Range:
From [73] SPLL to [74] SPHL (E.U.).
[77] SP 3 - Set Point 3
Available:
When at least one output is programmed as con-
trol output and [72] nSP > 2.
Range:
From [73] SPLL to [74] SPHL engineering units.
[78] SP 4 - Set Point 4
Available:
When at least one output is programmed as con-
trol output and [72] nSP = 4.
Range:
From [73] SPLL to [74] SPHL (E.U.).
[79] SPAt - Selection of the active Set point
Available:
When at least one output is programmed as
control output.
Range:
From SP1 to [72] nSP.
Notes: 1.
A [75] SPAt change produces the following actions:
•
When [80] SP.rt = SP, the remote set point will
