2.1 GENERAL NOTES ABOUT WIRING
1. Do not run input wires together with power cables.
2. External components (like zener barriers, etc.)
connected between sensor and input terminals may
cause errors in measurement due to excessive and/
or not balanced line resistance or possible leakage
currents.
3. When a shielded cable is used, it should be connected
at one point only.
4. Pay attention to the line resistance; a high line resistance
may cause measurement errors.

5. CONFIGURATION PROCEDURE
5.1 INTRODUCTION
When the instrument is powered, it starts immediately to work
according to the parameters values loaded in its memory.
The instrument behaviour and its performance are governed
by the value of the stored parameters.
At the first start up the instrument will use a “default” parameter
set (factory parameter set); this set is a generic one (e.g. a TC
J input is programmed).
WARNING! Before connecting the output actuators,
we recommend to configure the parameters to
suit your application (e.g.: input type, Control
strategy, alarms, etc.).
To change these parameters you need to enter the
“Configuration mode”.
Note: An engineering unit change (parameter [5] unit)
does NOT produce the automatic re-scaling
of all parameters related with the engineering unit.
5.2 INSTRUMENT BEHAVIOUR AT
POWER ON
At power ON the instrument can start in one of the following
mode depending on its configuration:
Auto mode without program functions.
–The upper display will show the measured value;
–The lower display will show the Set point value;
–The decimal figure of the less significant digit of the upper
display is OFF;
–The instrument is performing the standard closed loop control.
Manual mode (OPLO).
–The upper display will show the measured value;
–The lower display will show the power output and the MAN
LED will lite;
–The instrument does not perform Automatic control;
–The control output is equal to 0% and can be manually
modified by and buttons.
Stand-by mode (St.bY).
–The upper display will show the measured value;
–The lower display will show alternately the set point value
and the message St.bY or od;
–The instrument does not perform any control (the control
outputs are OFF);
–The instrument is working as an indicator.
Auto mode with automatic program start up.
–The upper display will show the measured value;
–The lower display will show one of the following information;
• The operative set point (when it is performing a ramp)
• The time of the segment in progress (when it is perform-
ing a soak);
NOTE VERY WELL: In all cases, the decimal figure of the
less significant digit of the lower display is lit.
We define all the above described conditions as
“Standard Display”.
5.3 HOW TO ENTER THE
“CONFIGURATION MODES”
The configuration parameters are collected in various
groups. Every group defines all parameters related with a
specific function (e.g.: control, alarms, output functions).
1. Push the button for more than 5 seconds.
The upper display shows PASS while the lower display
shows 0.
2. Using and buttons set the programmed password.
Notes: 1. The factory default password for configuration
parameters is equal to 30.
2. During parameter modification the instrument
continues to control the process.
In certain conditions, when a configuration
change can produce a heavy bump to the
process, it is advisable to temporarily stop the
control during the programming operations (the
control output will be Off). In this case, use a
password equal to 2000 + the programmed value
(e.g. 2000 + 30 = 2030).
The control will restart automatically when the
configuration procedure will be manually closed.
3. Push the button.
If the password is correct the display will show the acronym
of the first parameter group preceded by the symbol: ].
In other words the upper display will show: ]inp
(group of the Input parameters).
The instrument is in configuration mode.
5.3.1 How to exit the “Configuration mode”
Push button for more than 5 seconds, the instrument will
come back to the “standard display”.
5.4 KEYBOARD FUNCTIONS DURING
PARAMETER CHANGING
A short pression on the button exits from the current
parameter group and selects a new parameter group.
A long pression allows to close the configuration
parameter procedure (the instrument returns to the
“standard display”).
When the upper display is showing a group and the
lower display is blank, this key allows to enter in the
selected group.
When the upper display is showing a parameter and
the lower display is showing its value, this key allows
to store the selected value for the current parameter
and access the next parameter within the same group.
Increases the value of the selected parameter.
Decreases the value of the selected parameter.
+ These two keys allow to return to the previous
group. Proceed as follows:
Push the button and maintaining the pressure,
push the button; release both the buttons.
Note: The group selection is cyclic as well as the selection
of the parameters in a group.

5.5 FACTORY RESET - DEFAULT
PARAMETERS LOADING PROCEDURE
Sometime, e.g. when you re-configure an instrument
previously used for other works (or by other people) or when
you have made too many errors during configuration and
you decided to re-configure the instrument, it is possible to
restore the factory configuration.
This action allows to put the instrument in a defined
condition (the same it was at the first power ON).
The default data are those typical values loaded in the
instrument prior to ship it from factory.
To load the factory default parameter set, proceed as follows:
1. Press the button for more than 5 seconds;
2. The upper display will show PASS while the lower display
shows 0;
3. Using and buttons set the value -481;
4. Push button;
5. The instrument will turn OFF all LEDs for a few seconds,
then the upper display will show dFLt (default) and after
that all LEDs are turned ON for 2 seconds.
At this point the instrument restarts as for a new power ON.
The procedure is complete.
Note: The complete list of the default parameters is available
in Appendix A.
5.6 PARAMETERS CONFIGURATION
In the following pages we will describe all the instrument
parameters. However, the instrument will only show
those parameters applicable to the hardware options in
accordance with the specific instrument configuration
(i.e.: setting AL1t [Alarm 1 type] to nonE [not used], all
parameters related to alarm 1 will be skipped).

Notes: 1. When a TC or RTD input is selected and a decimal
figure is programmed (see the next parameter) the
max. displayed value becomes 999.9°C or 999.9°F.
2. All changes to SEnS parameter setting will force the
[2] dP = 0 and it will change all parameters related
with dP (e.g. set points, proportional band, etc.).
[2] dP - Decimal point position
Available: Always.
Range: When [1] SenS = Linear input: 0... 3.
When [1] SenS different from linear input: 0 or 1.
Note: All changes to decimal point position will produce a
change to all the parameters related with it
(e.g.: set points, proportional band, etc.).
[3] SSc - Initial scale read-out for linear inputs
Available: When a linear input is selected by [1] SenS.
Range: -1999... 9999.
Notes: 1. SSc defines, for linear inputs, the value that is to
be displayed when the instrument measures the
minimum measurable value.
The instrument is able to display the measured
value until it reaches a value of 5% lower than SSc,
below which shows the Underrange message.
2. It is possible to set an initial scale read-out higher
than the full scale read-out in order to obtain a
reverse read-out scaling.
E.g.:
0 mA = 0 mBar and 20 mA = -1000 mBar (vacuum).
[4] FSc - Full scale read-out for linear input
Available: When a linear input is selected by [1] SenS.
Range: -1999... 9999
Notes: 1. FSc defines, for linear inputs, the value that is to
be displayed when the instrument measures the
maximum measurable value.
The instrument is able to display the measured
value until it reaches a value of 5% higher than
FSc, above which shows the Overrange message.
2. It is possible to set a full scale read-out lower
than the initial scale read-out in order to obtain a
reverse read-out scaling.
E.g.:
0 mA = 0 mBar and 20 mA = -1000 mBar (vacuum).

[5] unit - Engineering unit
Available: When a temperature sensor is selected by
[1] SenS parameter.
Range: °c = Celsius;
°F = Fahrenheit.
Note: An engineering unit modification does NOT produce
the automatic re-scaling of all parameters related
with the engineering unit (e.g. alarm thresholds,
proportional band, etc.).
[6] FiL - Digital filter on the measured value
Available: Always.
Range: oFF (No filter) 0.1 to 20.0 s
Note: This is a first order digital filter applied on the measured
value. For this reason it will affect the measured value
but also the control action and the alarms behaviour .
[7] inE - Selection of the Sensor Out of Range type
that will enable the safety output value
Available: Always.
Range: our = When an overrange or an underrange is
detected, the power output will be forced to
the value of [8] oPE parameter.
or = When an overrange is detected, the power
output will be forced to the value of [8] oPE
parameter.
ur = When an underrange is detected, the power
output will be forced to the value of [8] oPE
parameter.
[8] oPE - Safety output value
Available: Always.
Range: -100... 100 % (of the output).
Notes: 1. When the instrument is programmed with one control
action only (heat or cool), setting a value outside of the
available output range, the instrument will use Zero.
E.g.: When heat action only has been programmed,
and oPE is equal to -50% (cooling) the instrument
will use the zero value.
2. When ON/OFF control is programmed and an out
of range is detected, the instrument will perform
the safety output value using a fixed cycle time
equal to 20 seconds.
[9] io4.F - I/O4 function selection
Available: Always.
Range: on = Out 4 forced to ON (used as a transmitter
power supply);
out4 = Used as digital output 4;
dG2.c = Digital input 2 for dry contact;
dG2.U= Digital input 2 driven by 12... 24 VDC.
Notes: 1. Setting [9] io4.F = dG2.C or dG2V, the parameter
[24] O4F becomes not visible while [11] diF2
parameter becomes visible.
2. Setting [9] io4F = on the [24] O4F parameter and
the [11]diF2 parameter will NOT be visible.
3. Setting [9] io4F different from dG2.c or dG2.U, the
instrument forces [12] diF2 parameter to nonE.
If [11] diF1 was equal to (SP4 or UPDN) it will be
forced to nonE.
4. The transfer from [9] io4F = on to [9] io4F = Out4
makes parameter [24] O4F visible equal to nonE.

Available: When [28] AL1t is different from nonE or
[28] AL1t is different from SE.br.
Range: 1... 9999 engineering units
Notes: 1. The hysteresis value is the difference between
the Alarm threshold value and the point the Alarm
automatically resets.
2. When the alarm threshold plus or minus the
hysteresis is out of input range, the instrument
will not be able to reset the alarm.
Example: Input range 0... 1000 (mBar).
–Set point equal to 900 (mBar);
–Deviation low alarm equal to 50 (mBar);
–Hysteresis equal to 160 (mBar)
the theoretical reset point is 900 - 50 + 160 = 1010 (mBar)
but this value is out of range.
The reset can be made only by turning the instrument
OFF, removing the condition that generates the alarm and
then turn the instrument ON again.
–All band alarms use the same hysteresis value for both
thresholds;
–When the hysteresis of a band alarm is bigger than the
programmed band, the instrument will not be able to reset
the alarm.
Example: Input range 0... 500 (°C).

]LbA group - Loop break alarm
General note about LBA alarm
The LBA operate as follows: applying the 100% of the power
output to a process, the process variable, after a time due to
the process inertia, begins to change in a known direction (in-
creases for an heating action or decreases for a cooling action).
Example: If I apply 100% of the power output to a furnace,
the temperature must go up unless one of the component in
the loop is faulty (heater, sensor, power supply, fuse, etc...)
The same philosophy can be applied to the minimum power.
In our example, when I turn OFF the power to a furnace, the
temperature must go down, if not the SSR is in short circuit,
the valve is jammed, etc..
LBA function is automatically enabled when the PID requires
the maximum or the minimum power.
When the process response is slower than the programmed
limit the instrument generates an alarm.
Notes: 1. When the instrument is in manual mode, the LBA
function is disabled.

Ascon Tecnologic - KR5 Line - ENGINEERING MANUAL - Vr. 0.0 PAG. 14
2. When LBA alarm is ON the instrument continues
to perform the standard control. If the process
response comes back into the programmed limit,
the instrument automatically resets the LBA alarm.
3. This function is available only when the programmed
control algorithm is equal to PID (Cont = PID).

[54] LbAS - Delta measure used by loop break
alarm (loop break alarm step)
Available: When [52] LbAt is different from oFF.
Range: From 1 to 9999 engineering units.
[55] LbcA - Condition for LBA enabling
Available: When [52] LbAt is different from oFF.
Range: uP = Enabled when the PID requires the maxi-
mum power only;
dn = Enabled when the PID requires the mini-
mum power only:

Enabled in both condition (when the PID re-
quires the maximum or the minimum power).
LBA application example:
LbAt (LBA time) = 120 seconds (2 minutes);
LbAS (delta LBA) = 5°C.
The machine has been designed in order to reach 200°C in
20 minutes (20°C/min).
When the PID demands 100% power, the instrument starts
the time count.
During time count if the measured value increases more
than 5°C, the instrument restarts the time count. Otherwise
if the measured value does not reach the programmed delta
(5°C in 2 minutes) the instrument will generate the alarm.

[57] Auto - Auto tune selection
Ascon Tecnologic has developed three auto-tune algorithms:
–Oscillating auto-tune;
–Fast auto-tune;
–EvoTune.
1. The oscillating auto-tune is the usual auto-tune and:
• It is more accurate;
• Can start even if PV is close to the set point;
• Can be used even if the set point is close to the
ambient temperature.
2. The fast type is suitable when:
• The process is very slow and you want to be opera-
tive in a short time;
• When an overshoot is not acceptable;
• In multi loop machinery where the fast method reduces
the calculation error due to the effect of the other loops.
3. The EvoTune type is suitable when:
• You have no information about your process;
• You can not be sure about the end user skills;
• You desire an auto tune calculation independently
from the starting conditions (e.g. set point change
during tune execution, etc).
Note: Fast auto-tune can start only when the measured
value (PV) is lower than (SP + 1/2SP).

6 = EvoTune with automatic start at the first
power up only;
7 = EvoTune with manual start;
8 = EvoTune with automatic restart at all set
point change.
Note: All auto-tunes are inhibited during program execution.
[58] tunE - Manual start of the auto-tune
Available: When [56] cont = PID.
Range: oFF = The instrument is not performing the auto-tune;
on = The instrument is performing the auto-tune.
[59] HSEt - Hysteresis of the ON/OFF control
Available: When [56] cont is different from PID.
Range: 0... 9999 engineering units.
[60] Pb - Proportional band
Available: When [56] cont = PID.
Range: 1... 9999 engineering units.

[64] tcH - Cycle time of the heating output
Available: When at least one output is programmed in order
to be the heating output (H.rEG), [56] cont = PID
Range: 1.0... 130.0 seconds.
[65] rcG - Power ratio between heating and cooling
action (relative cooling gain)
The instrument uses the same PID parameter set for heat
and for cool action but the efficiency of the two actions is
usually different.
This parameter allows to define the ratio between the efficien-
cy of the heating system and the efficiency of the cooling one.
An example will help us to explain the philosophy.
Consider one loop of a plastic extruder. The working tem-
perature is equal to 250°C.
When you want to increase the temperature from 250 to
270°C (DT = 20°C) using 100% of the heating power (resis-
tor), you will need 60 seconds.
On the contrary, when you want to decrease the temperature
from 250 to 230°C (DT = 20°C) using 100% of the cooling
power (fan), you will need 20 seconds only.
In our example the ratio is equal to 60/20 = 3 ([65] rcG = 3)
and it say that the efficiency of the cooling system is 3 time
more efficient of the heating one.
Available: When two control actions are programmed
(H.rEG and c.rEG) and
[55] cont = PID.
Range: 0.01... 99.99.
Note: Auto-tune functions calculate this value.
[66] tcc - Cycle time of the cooling output
Available: When at least one output is programmed in order
to be the cooling output (c.rEG), [56] cont = PID.
Range: 1.0... 130.0 seconds.
[67] rS - Manual reset (integral pre-load)
It allows to drastically reduce the undershoot due to a
hot restart. When your process is steady, the instrument
operates with a steady power output (e.g.: 30%).
If a short power down occurs, the process restarts with a
process variable close to the set point while the instrument
starts with an integral action equal to zero.
Setting a manual reset equal to the average power output
(in our example 30%) the instrument will start with a power
output equal to the value it will use at steady state (instead
of zero) and the undershoot will become very little (in theory
equal to zero).
Available: When [56] cont = PID.
Range: -100.0... +100.0%.
[68] Str.t - Servomotor stroke time
Available: When [56] cont = 3Pt.
Range: 5... 1000 seconds.
[69] db.S - Servomotor dead band
Available: When [56] cont = 3Pt.
Range: 0... 100%.
[70] od - Delay at power up
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 up) the instrument remains in
stand by mode before to start all other functions
(control, alarms, program, etc.).
2. When a program with automatic start at power up

Ascon Tecnologic - KR5 Line - ENGINEERING MANUAL - Vr. 0.0 PAG. 16
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 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.

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 simultane-
ously 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-

Ascon Tecnologic - KR5 Line - ENGINEERING MANUAL - Vr. 0.0 PAG. 17
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.
Range: rSP = The value coming from serial link is used
as remote set point (RSP);
trin = The value coming from serial link will be
algebraically added to the local set point
selected by A.SP and the sum becomes
the operative set point;
PErc = The value coming from serial will be scaled
on the input range and this value will be
used as remote set point.
Note: A [82] SPrt change produces the following actions:
• When [82] SP.rt = rSP - 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.
Example: A 6 zone reflow-oven for PCB.
The master unit sends its set point value to 5 other zones
(slave controllers).
The Slave zones use it as a set point trim.
The first zone is the master zone and it uses a set point
equal to 210°C.
The second zone has a local set point equal to -45°C.
The third zone has a local set point equal to -45 (°C).
The fourth zone has a local set point equal to -30.
The fifth zone has a local set point equal to +40.
The sixth zone has a local set point equal to +50.
In this way, the thermal profile will be the following:
–Master SP = 210°C;
–Second zone SP = 210 -45 = 165°C;
–Third zone SP = 210 -45 = 165°C;
–Fourth zone SP = 210 - 30 = 180°C;
–Fifth zone SP = 210 + 40 = 250°C;
–Sixth zone SP = 210 + 50 = 260°C.
Changing the SP of the master unit, all the other slave units
will immediately change their operative set point.
[83] SPLr - Local/remote set point selection
Available: When at list one output is programmed as control

[90] di.CL - Display colour
Available: Always.
Range: 0 = The display colour is used to show the
actual deviation (PV - SP);
1 = Display red (fix);
2 = Display green (fix);
3 = Display orange (fix).
[91] AdE - Deviation for display colour management

Range: 1... 9999 engineering units.
[92] diS.t - Display time out
Available: Always.
Range: oFF = The display is always ON;
0.1... 99.59 minutes and seconds.
Note: This function allows to turn OFF the display when no
alarm is present and no action is made on the instrument.

returns to the normal operation.
[93] FiLd - Filter on the displayed value
Available: Always.
Range: oFF = Filter disabled;
From 0.0 (oFF) to 20.0 engineering units.
Note: This is a “window filter” related to the set point; it is applied
to the displayed value only and it have no effect on the
other functions of the instrument (control, alarms, etc.).
[95] dSPu - Instrument Status at power up
Available: Always.
Range: AS.Pr = Starts in the same way it was prior to the
power down;
Auto = Starts in Auto mode;
oP.0 = Starts in manual mode with a power output
equal to zero;
St.bY = Starts in stand-by mode.
Notes: 1. When you change the value of [96] oPr.E, the in-
strument forces [97] oPEr parameter equal to Auto.
2. During program execution the instrument stores
the segment currently in use and, by a 30 minutes
interval, it stores also the elapsed time of the soak.
If a power down occurs during program execution,
at the next power up the instrument is able to
continue the program execution starting from the
segment in progress at power down and, if the
segment was a soak, it is also capable to restart
from the soak time minus the stored elapsed time.
In order to obtain this features, the “[95] dSPu -
Status of the instrument at power up” parameter
must be set to “AS.Pr”.
If the “[95] dSPu” parameter is different from “AS.
Pr” the storing function is inhibited.

These instruments are equipped with 2 pages of 4 program
each (8 programs total).
Each program is composed by 6 groups of 2 steps each (12
steps total)
The first step is a ramp (used to reach the desired set point),
the second is a soak (on the desired set point).
When a RUN command is detected the instrument aligns
the operative set point to the measured value and starts to
execute the first ramp of the selected program.
When you need a program with more than 12 segments it is
possible to link the selected program with the next one.
Example:
You are preparing the Page 1, Program 1 but you need 20
steps.
At the end of the 12 segments of Program 1 you will find a
parameter “[164] P1.c2 – Program 1 continue on Program 2”;
setting YES you will link Program 1 with Program 2.
Now you can program the 8 steps (of Program 2) necessary
to complete your profile.
Running Program 1, the instrument performs the first
program followed by the 8 steps of program 2.
In addition, every soak is equipped with a wait band which
suspends the time count when the measured value goes out
of the defined band (guaranteed soak).
Moreover, for each segment it is possible to define the status
of two events. An event can drive an output and make an
action during one or more specific program steps.
Some additional parameters allow to define the time scale,
the automatic RUN conditions, the repetition number and the
instrument behaviour at the end of the program.
Notes: 1. All steps can be modified during program execution.
2. During program execution the instrument stores the
segment currently in use and, by a 1 minute interval,
it stores also the elapsed time of the soaks.
If a power down occurs during program execution, at
the next power up the instrument is able to continue
the program execution starting from the segment in
progress at power down and, if the segment was a
soak, it is also capable to restart from the soak time
minus the elapsed time memorized.
In order to obtain this features, the [95] dSPu
“Status of the instrument at power up” parameter
must be set to AS.Pr.
If [95] dSPu value is different from AS.Pr, the
storing function will be inhibited.
The structure of the programmer parameters is based on:
–1 group with the “global” parameters [PrG group](page
selection, active program selection status of the active
program, etc.).

Ascon Tecnologic - KR5 Line - ENGINEERING MANUAL - Vr. 0.0 PAG. 20
–1 group for every program (Page 1:Pr1, Pr2, Pr3 and Pr4
and Page 2: Pr5, Pr6, Pr7, Pr8).
NOTE VERY WELL:
In paragraph 4 we will described all parameters related with
the programmer and their action during program execution.
5.7 HOW TO EXIT FROM PARAMETER
CONFIGURATION
When all the important steps of the configuration procedure
are completed, it is possible to exit from the parameters
configuration procedure:
• Push button.
• Push button for more than 10 s. The instru-
ment returns back to the “standard display”.
6. PARAMETER PROMOTION
Another important step of the instrument configuration is
caused by the possibility to create a custom HMI (interface)
in order to make the instrument easy to use for the operator
and comfortable for the assistance.
By a special procedure, named promotion, the OEM can
create two parameter subsets.
The first one is the “limited access” level. This subset is protected
by the password programmed by [86] PAS2 parameter.
The last subset is the “Operator” set (Level1). This level is
NOT password protected.
Notes: 1. The “limited access” parameter are collected in a list;
2. The elements of the “limited access” parameters
are programmable and can be made according to
your needs.
3. The parameter list of the operator level is the
same programmed for “limited access” level but
only specified parameters can be displayed and
modified. This set must be create according to
your requirements.
6.1 PARAMETER PROMOTION
PROCEDURE
The limited access parameter set is a list and it is a subset
of the configuration parameters.
Before to start the promotion procedure, we suggest to
operate as follows:
1. Prepare the exact parameter list you want to make
accessible for limited access.
2. Define which of the selected parameters must be
available also at Operator level.
Example: I would like to obtain the following limited access list:
• AL1 - Alarm 1 threshold;
• AL2 - Alarm 2 threshold;
• SP - First set point;
• SP2 - Second set point;
• A.SP - Set point selection;
• tunE - Manual start of the auto-tune.
But I want that the operator will be able to change: the SP
value and the AL1 value. In this case the promotion list is:
Parameter Promotion Limited Access Operator
- AL1 - oPEr AL1 AL1
- AL2 - ASS AL2
- SP - oPEr SP SP
- SP2 - ASS SP2
- A.SP- ASS A.SP
- tunE - ASS Tune
Now, proceed as follows:
1. Push the button for more than 3 seconds.
2. The upper display shows PASS while the lower display
shows 0.
3. By and buttons set a password equal to -81.
4. Push button.
The instrument displays the acronym of the first
configuration parameter group
]
inP.
5. Press the button to select the group of the first
parameter of your list.
6. Press the button to select the first parameter of your list.
7. The upper display shows the acronym of the parameter
while the lower display its current promotion level.
The promotion level is defined by a message.
The possible values are:
conF: The parameter is NOT promoted and is
present only in configuration.
In this case the number is forced to zero.
ASS: The parameter has been promoted to the
limited access level.
The number indicates the position in the limited
access list.
oper: The parameter has been promoted to the
Operator level.
The number indicates the position in the limited
access list.
8. By and buttons assign to this parameter the
desired level.
9. Select the second parameter that you want to add to the
assistance level and repeat step 6, 7 and 8.
10. Repeat step 5, 6, 7, 8 until the list has been completed.
11. When you need to exit from promotion procedure, push
button and maintain the pressure for more than 10 s.
The instrument returns back to the “standard display”.
Example: In the previous example, I have set for SP1 a
promotion value equal to ASS.
If now I set for SP1 a promotion value equal to oPEr, the
Limited Access list and the Operator list become.
Parameter Promotion Limited Access Operator
- AL1 - oPEr AL1 AL1
- AL2 - ASS AL2
- SP - oPEr SP SP
- SP2 - oPEr SP2 SP2
- A.SP- ASS A.SP
- tunE - ASS Tune
