When an auto-tune with automatic start at
power up and “od” function are programmed, the
autotune will start at the end of “od” delay.
[71] St.P - Max. 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
up and soft start function are programmed, the
instrument performs the soft start and than the
program function.
4.
The auto-tune function will be performed after soft
start function.
5.
The Soft start function is available also when ON/
OFF contro l is used.
[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.
[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 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 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 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 [76] SPLL end [77]
SPHL. If an SP is out of this range, the instrument
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
instrument checks all local set points (SP, SP2,
SP3 and SP4 parameters) and all the program set
points ([95] Pr.S1, [100] Pr.S2, [105] Pr.S3, [110]
Pr.S4 parameters). If an SP is out of this range, the
instrument forces it to the max. acceptable value.
2.
A [75] SPLL change produces the following actions:
• When [82] SP.rt = SP the remote set point will
be forced to be equal to the active set point;
• When [82] SP.rt = trim the remote set point
will be forced to zero;
• When [82] SP.rt = PErc the remote set point
will be 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] SPHL 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 to [76] SPHL engineering units.
[80] SP 4 - Set Point 4
Available:
When at least one output is programmed as con-
trol output and [74] nSP =4.
Range:
From [75] SPLL to [76] SPHL engineering units.
[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
will be forced to be equal to the active set point;
• When [82] SP.rt = trin - the remote set point
will be forced to zero;
• When [82] SP.rt = PErc - the remote set
point will be forced to zero.
2.
SP2, SP3 and SP4 selection will be shown
only when the relative set point is enabled (see
[74] nSP parameter).
[82] SP.rt - Remote set point type
These instruments will communicate with each other, using
RS 485 serial interface without a PC. An instrument can be
set as a Master while the other are Slave units. The Master
unit can send his operative set point to the slave units. In this
way, for example, it is possible to change simultaneously the
set point of 20 instruments by changing the set point of the
master unit (e.g. hot runner application).
SP.rt parameter defines how the slaves units will use the
value coming from serial link.
Parameter [100] tr.SP (selection of the value to be retrans-
mitted (Master)) parameter allows to define the value sent by
master unit.
Available:
When at least one output is e programmed as
control output and the serial interface is present.
