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, the shield should be connected to ground 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 performances are governed by the value of the stored parameters.
At the first start up the instrument uses a “default” parameters set (factory parameter set); this set is a generic one (e.g. a
TC J input is programmed).
We recommend to modify the parameter set to suit your application (e.g. set the right input type, Control strategy, define an alarm, etc.).
To change these parameters you will need to enter the
“Configuration procedure”.
D [6] Unit (Engineering Unit) parameter allows to set the temperature units in accordance with the user needs
(°C/°F).
Be careful!
Do not change the Engineering Unit during process control as the temperature values inserted by the user (thresholds, limits etc.) are not automatically rescaled by the instrument.
5.1.1 Access levels to the parameter modifications and their password
The instrument have one complete parameter set. We call this set “Configuration parameter set” (or “Configuration parameters”).
The access to the configuration parameters is protected by a programmable password (password level 3).
The configuration parameters are collected in various groups. Every group defines all parameters related with a specific function (e.g. control, alarms, output functions).
Note: The instrument will show only the parameters consistent with the specific hardware and in accordance with the value assigned to the previous parameters (e.g. if you set an output as “not used” the instrument will mask all other parameters related with this output).
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 shows the measured value;
– The lower display shows the Set point value;
– The decimal figure of the less significant digit of the lower display is OFF;
– The instrument is performing the standard closed loop control.
Manual mode (oPLo) :
– The upper display shows the measured value;
– The lower display shows alternately the power output and the message oPLo ;
– 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 shows the measured value;
– The lower display shows alternately the set point value and the message St.bY
or od ;
– The instrument performs no control (the control outputs are OFF);
– The instrument is working as an indicator.
Auto mode with automatic program start up :
– The upper display shows the measured value;
– The lower display shows 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 performing a soak);
• The set point value alternate with the message St.bY
.
– 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 Entering the configuration mode
1. Push the button for more than 3 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. All parameter modifications are protected by a time out. If no button is pressed for more than 10 seconds the instrument returns automatically back to the
Standard display, the new value of the last selected parameter is lost and the parameter modification procedure is closed. Sometimes can be useful to enter the parameter configuration procedure with no timeout (e.g.: the first time an instrument is configured). In this case, use a password equal to the previously set password + 1000 digits
(e.g.: 1000 + 30 [default] = 1030).
It is always possible to manually end the parameter configuration procedure (see the next paragraph).
3. 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 shows the acronym of the first parameter group preceded by the symbol “
]
”.
In other words the upper display shows:
] inP .
The instrument is in configuration mode.
5.4 Exiting the configuration mode
Push the button for more than 5 seconds, the instrument will return to the “Standard display”.
Ascon Tecnologic - K Series - ENGINEERING MANUAL - PAG. 5
5.5 Keyboard functions during the parameter modification
A short pression on the button allows to exit the current parameter group and select the next one. 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, allows to enter in the selected group.
When the upper display is showing a parameter and the lower display is showing its value, it allows to store the selected value and to go to the next parameter within the same group.
Increases the value of the selected parameter.
Decreases the value of the selected parameter.
+ These buttons allow to return to the previous group.
Proceed as follows:
Push the button and maintaining the pressure push the button. At this point, release both the buttons.
Note: The group selection is cyclic as well as the selection of the parameters in a group.
5.6 Factory reset - Default parameters loading procedure
Sometimes, e.g. when you re-configure an instrument previously used for other works or from 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 condition it was at first Power ON).
The default data are those typical values loaded in the instrument before being shipped 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. By and buttons set the value -481;
4. Push button;
5. The instrument turns OFF all LEDs for some seconds, then the upper display will show dfLt (default) and then all LEDs are turned ON for 2 seconds. At this point the instrument it will restart as for a new Power ON.
The procedure is complete.
Note: The complete list of the default parameter is available in Appendix A .
5.7 All parameters configuration
In the following pages we will describe all the parameters of the instrument. However, the instrument will only show the parameters applicable to its hardware options in accordance with the specific instrument configuration (i.e. setting AL1t
[Alarm 1 type] equal to nonE [not used], all parameters related with the alarm 1 will be skipped).

• When the contact is open, the control action is an heating action and the active set point is SP1.
• When the contact is closed, the control action is a cooling action and the active set point is SP2.
2. When diF1 is equal to 18, diF2 setting is forced to 18 and diF2 value and cannot perform another additional function.
3. When diF1 and diF2 are equal to 18, the set point selection will be in accordance with the following table

.
Notes: 1. The hysteresis value is the difference between the Alarm threshold value and the point the where the Alarm automatically resets.
2. When the alarm threshold plus or minus the hysteresis is out from the input range, the instrument will not be able to reset the alarm.
Example: Input range from 0 to 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 wich generated the alarm and turning the instrument ON again.
3. All band alarms use the same hysteresis value for both thresholds.
4. 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);
- Set point equal to 250 (°C);
- Relative band alarm;
- Low threshold equal to 10 (°C);
- High threshold equal to 10 (°C);
- Hysteresis equal to 25 (°C).

LbA Group - Loop break alarm
General note about LBA alarm
The LBA operate as follows:
When you apply 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 (increases 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 furnaces, 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.
2. When LBA alarm is ON the instrument continue to perform the standard control. If the process response come back into the programmed limit, the instrument reset automatically the LBA alarm.
3. This function is available only when the programmed control algorithm is equal to PID (Cont = PID).
[48] LbAt - LBA time
Available: When [52] Cont = PID.
Range: • oFF = LBA not used;

oFF .
Enabled when the PID requires the maxidn Enabled when the PID requires the minimum power only both Enabled in both condition (when the PID requires the maximum or the minimum power).
Ascon Tecnologic - K Series - ENGINEERING MANUAL - PAG. 12
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 the 100% of the 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.

[53] Auto - Auto tune selection
Ascon Tecnologic has developed two auto-tune algorithms:
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 auto-tune is suitable when:
• The process is very slow and you want to be operative in a short time;
• When an high overshoot is not acceptable;
• In multi loop machinery where the fast method reduces the calculation error due to the effect of the other loops.
Note: Fast auto-tune can start only when the measured value (PV) is lower than (SP + 1/2SP).

[63] tcrH - Cycle time of the heating output
Available: When at least one output is programmed in order to be the heating output (H.rEG), [52] cont = PID and [55] SELF = no.
Range: • When [62] H.Act = SSr: 1.0... 130.0 seconds;
• When [62] H.Act = reLY: 20.0... 130.0 seconds;
• When [62] H.Act = SLou: 40.0... 130.0 seconds.
Note: Auto-tune functions calculate this value but, when necessary, it is possible to set it manually.
[64] PrAt - 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 are usually different.
This parameter allows to define the ratio between the efficiency of the heating system and the efficiency of the cooling one.
An example will help us tu explain you the philosophy.
Consider one loop of a plastic extruder.
The working temperature is equal to 250°C.
When you want to increase the temperature from 250 to
270°C ( Δ 20°C) using 100% of the heating power (resistor), you will need 60 seconds.
On the contrary, when you want to decrease the temperature from 250 to 230°C ( Δ 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 ([60] PrAt = 3) and says that the efficiency of the cooling system is 3 times more efficient than the heating one.
Available: When two control action are programmed (H.rEG and c.rEG) and [52] cont = PID and [55] SELF = no.
Range: 0.01... 99.99.
Note: Auto-tune functions calculate this value.
[65] c.Act - Cooling output (C.rEG) actuator
Available: When at least one output is e programmed in order to be the cooling output (c.rEG),
[52] cont = PID and [55] SELF = no.
Range: SSr Solid state relay output; rELY Relay or contactor;
SLou Slow actuator (e.g. compressors).
Note: For more details see [62] h.Act parameter.
[66] tcrc - Cycle time of the cooling output
Available: When at least one output is programmed in order to be the cooling output (c.rEG),
[52] cont = PID and [55] SELF = no.
Range: • When [65] c.Act = SSr: 1.0... 130.0 s;
• When [65] c.Act = reLY: 20.0... 130.0 s;
• When [65] c.Act = SLou: 40.0... 130.0 s.
Note: Auto-tune functions calculate this value but, when necessary, it is possible to set it manually
[67] rS - Manual reset (integral pre-load)
rS allows to drastically reduces 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 [52] cont = PID and [55] SELF = no.
Range: -100.0... 100.0%.

[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 control 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 control 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 control 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
Ascon Tecnologic - K Series - ENGINEERING MANUAL - PAG. 15
be forced to be equal to the active set point;
• When [80] SP.rt = trin, the remote set point will be forced to zero;
• When [80] SP.rt = PErc, the remote set point will be forced to zero.
2. The SP2, SP3 and SP4 selection is possible only if the relative set point is enabled (see [75] nSP parameter).
[80] 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 others are (as usual) 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 slave units will use the value coming from serial link.
The [125] tr.SP [Selection of the value to be retransmitted
(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 SPAt 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: An [80] SPrt change produces the following actions:
• When [80] SP.rt = rSP, the remote set point will be forced to be equal to the active set point;
• When [80] SP.rt = trin, the remote set point will be forced to zero;
• When [80] 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.
[81] SPLr - Local/remote set point selection
Available: When at least one output is programmed as control output.
Range: Loc rEn
Local set point selected by [79] SPAt;
Remote set point (coming from serial link).

Range: 0.01... 99.99 units per minute; inF Ramp disabled (step transfer).
General note about remote set point
When the remote set point (RSP) with trim action is programmed, the local set point range becomes the following: from [73] SPLL+ RSP to [74] SPHL - RSP.

]
PrG Group - Programmer function parameter
These instruments are able to perform a set point profile composed by 4 groups of 2 steps each (8 step 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.
In addition, each 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 and the instrument behaviour at program end.
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 30 minutes interval, it stores also the elapsed time of the soaks.
If a power down occurs during the program execution, at the next Power ON 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 [120] dSPu -
Status of the instrument at Power ON parameter must be set to AS.Pr

The most important step of the configuration procedure is completed.
In order to exit from configuration parameter procedure, proceed as follows:
– Press button;
– Press button for more than 10 seconds;
– The instrument returns to the “Standard display”.
Ascon Tecnologic - K Series - ENGINEERING MANUAL - PAG. 21
6. PARAMETER PROMOTION
Another important step of the instrument configuration is due to 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 [114] PAS2 parameter.
The last subset is the “Operator” set (Level1). This level si
NOT password protected.
Notes: 1. The “Limited access” parameters are collected in a list.
2. The sequence of the “Limited access” parameters is programmable and can be made according to your needs.
3. The parameter sequence 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, so that, before to start promotion procedure, we suggest to operate as follows:
1. Prepare the exact parameter list you want to make accessible for limited access.
2. Give a number to the desired parameters using the same sequence you want to have in the limited access.
3. Define which of the selected parameters will be available also at Operator level.
Example: I would like to obtain the following limited access list:
• OPEr - Operative mode selection;
• SP1 - First set point;
• SP2 - Second set point;
• SPAt - Set point selection;
• AL1 - Alarm 1 threshold;
• AL2 - Alarm 2 threshold;
• Pb - Proportional band;
• Int - Integral time;
• dEr - Derivative time;
• Aut.r - Manual start of the auto-tune.
But I want that the operator is enabled in changing: the operative mode, the SP1 and the AL1 values.
In this case the promotion list is:
Parameter Promotion Limited Access Operator
- OPEr -
- SP1 -
- SP2 -
- SPAt -
- AL1 -
- AL2 -
- Pb -
- Int -

Now, proceed as follows:
1. Push the button for more than 3 seconds.
2. The upper display will show display shows 0 .
PASS while the lower
3. By and buttons set a password equal to - 81.
4. Push button.
The instrument shows the acronym of the first configuration parameter group ] inP .
5. By button select the group of the first parameter of your list.
6. With the button select the first parameter of your list
7. The upper display will show the acronym of the parameter while the lower display shows its current promotion level.
The promotion level is defined by a letter followed by a number. The letter can be:
“ c ” The parameter is NOT promoted and is present only in configuration. In this case the number is forced to zero.
“ A ” Indicates that the parameter has been promoted to the limited access level. The number shows its position in the limited access list.
“ o ” Indicates that the parameter has been promoted to the Operator level. The number shows its position in the limited access list.
8. By and buttons assign to this parameter the desired position.
Note: Setting a value different from 0 the letter “ c ” changes automatically to “ A ” and the parameter is automatically promoted to the limited access level.
9. In order to modify the level from “Limited access” to “Operator” and vice versa, press button and, maintaining the pressure, press button.
10. The letter changes from “ A ” to “ o ” and vice versa. Select the second parameter that you want to add to the “Limited access” level and repeat steps 6, 7 and 8.
11. Repeat steps 5, 6, 7 and 8 until the list has been completed.
12. When you need to exit the promotion procedure, push button and maintain the pressure for more than 10 s.
The instrument returns to the “Standard display”.
Note: When you set the same number to two parameter, the instrument will use only the last programmed parameter.
Example: In the previous example, I must set for SP2 a promoton value equal to A3.
If now I set for SP3 a promotion value equal to o3, the Limited Access list and the operator list becomes:

7. OPERATIVE MODES
As we said at Paragraph 5.1, when the instrument is powered, starts immediately to work accordingly to the stored parameters value.
In other words, the instrument has only one status, the “run time” status.
During “run time” we can force the instrument to operate in three different modes: Automatic mode, Manual mode or
Stand by mode.
– In Automatic mode the instrument drives automatically the control output according to the parameter value set and the setpoint/measured value.
– In Manual mode the upper display shows the measured value while the lower shows the power output alternately to the oPLo message and the instrument allows you to manually set the output power.
No Automatic action will be made.
– In stand by mode the instrument operates as an indicator. It shows the measured value and forces the outputs to zero.
As we have seen, it is always possible to modify the value assigned to a parameter independently from the operative mode selected.
7.1 How to enter the “Operator level”
The instrument is showing the “Standard display”.
1. Press the button;
2. The upper display will show the acronym of the first parameter promoted to this level while the lower display shows its value;
3. With the and buttons assign to this parameter the desired value;
4. Press the button in order to store the new value and go to the next parameter;
5. When you want to reurn to the “Standard display” push the button for more than 5 seconds.
Note: The parameter modification of the Operator level is subject to a time out. If no button is pressed for more than 10 seconds, the instrument returns to the “Standard display” and the new value of the last selected parameter will be lost.
7.2 How to enter the “Limited Access Level”
The instrument is showing the “Standard display”.
1. Press the button for more than 5 seconds;
2. The upper display will show PASS while the lower display shows 0 .
3. With the and buttons set the value assigned to
[114] PAS2 (Level 2 password);
Notes: 1. The factory default password for configuration parameters is equal to 20.
2. All parameter modification are protected by a time out. If no button is pressed for more than 10 second the instrument returns automatically to the Standard display, the new value of the last selected parameter is lost and the parameter modification procedure is closed.
When you desire to remove the time out (e.g. for the first configuration of an instrument) you can use a password equal to 1000 plus the programmed password (e.g. 1000 + 20 [default] = 1020).
It is always possible to manually End the parameter configuration procedure (see below).
3. During parameter modification the instrument continues to perform the control.
In certain conditions (e.g. when a parameter change can produces a heavy bump to the process) it is advisable to temporarily stop the controller from controlling during the programming procedure (its control output will be Off). A password equal to 2000 + the programmed value
(e.g. 2000 + 20 = 2020) will switch the control out off during configuration. The control will restart automatically when the parameter modification procedure will be manually ended.
4. Press button;
5. The instrument will show on the upper display the acronym of the first parameter promoted to this level and on the lower display its value.
6. By and buttons assign to this parameter the desired value;
7. Press the button in order to memorize the new value and go to the next parameter;
8. When you want to return to the “Standard display” push the button for more than 5 seconds.
7.3 How to see but not modify the
“Limited Access Parameters”
Sometime it is necessary to give to the operator the possibility to see the value assigned to the parameter promoted in the Limited Access level but it is important that all changes are made by autorized personnel only.
In this cases, proceed as follows:
1. Press the button for more than 5 seconds;
2. The upper display will show display shows 0 .
PASS while the lower
3. By and buttons set the value -181 ;
4. Press button;
5. The upper display will show the acronym of the first parameter promoted to the level 2 and lower display shows its value;
6. Using button is possible to see the value assigned to all parameters present in level 2 but it will not be possible to modify it;
7. It is possible to return to the “Standard display” pushing the button for more than 3 seconds or pushing no buttons for more than 10 seconds.
7.4 Automatic Mode
7.4.1 Keyboard functions when the instrument is in Auto mode

Starts the “Direct set point modification” function (see below).
Displays the “Additional information” (see below).
Ascon Tecnologic - K Series - ENGINEERING MANUAL - PAG. 23
7.4.2 Direct set point modification
This function allows to modify rapidly the set point value selected by [79] SPAt (selection of the active Set point) or to the set point of the segment group (of the programmer) currently in progress.
The instrument is showing the “Standard display”.
1. Push button.
The upper display shows the acronym of the selected set point (e.g. SP2) while the lower shows its value.
Note: When the programmer is running, the instrument shows the set point of the group currently in use
(e.g. if the instrument is performing soak 3 the instrument shows [104] Pr.S3).
2. By and buttons, assign to this parameter the desired value;
3. Do not push any button for more than 5 second or push the button. In both cases the instrument stores the new value and returns to the “Standard display”.
Note: If the selected set point has not been promoted to the
Operator level, the instrument allows you to see the value but not to modify it.
7.4.3 Additional information
This instrument is able to show you some additional information that can help you in managing your system.
The additional information are related to how the instrument is programmed, hence in many cases, only part of these information are available.
1. When the instrument is showing the “Standard display” push button.
The lower display shows H or c followed by a number. This value is the current power output applied to the process.
H indicates that the action is a Heating action while c says that the action in progress is a Cooling action.
2. Push button again. When the programmer is running the lower display shows the segment currently performed and the Event status: r1.00
where the first character can be r for a ramp or S for a soak, the next digit shows the number of the segment (e.g.: S3 means Soak number 3) and the two
Less Significant Digits (LSD) indicate the status of the two events (the LSD is the Event 2);
3. Push button again. When the programmer is running the lower display shows the theoretical remaining time to the end of the program preceded by a P letter: P84.3
4. Push button again. When the wattmeter function is running the lower display shows U followed by the measured energy.
Note: The energy calculation will be in accordance with the [123] Co.tY parameter setting.
5. Push button again. When the “Worked time count” is running the lower display shows d for days or h for hours followed by the measured time.
6. Push button again. The instrument returns to the
“Standard display”.
Note: The additional information visualization is subject to a time out. If no buttons are pressed for more than 10 seconds the instrument automatically returns to the
Standard display.
7.4.4 The programmer function
In “Chapter 5” we have described all parameters related with the programmer and their action during program execution.
In this paragraph we give you some additional information and some application examples.
Note: The decimal point of the LSD of the lower display is used to show the programmer status independently from the displayed value selected by [114] diSP
(Display management).
Decimal point of the LSD
.
The relation between the programmer status and the
LED are the following:
• Program in RUN - The LED is ON;
• Program in Hold - The LED flashes fast;
• Program in Wait - The LED flashes slow;
• Program in end or reset - The LED is OFF.
Application example 1: Spray Paint Drying Booth.
When the operator is in the booth painting the car, the internal temperature must be 20°C and the air used for booth ventilation comes from outside.
Shutter
During the passivation and drying phases, the operator is out of the booth and the system closes the air shutter to recycle the internal air in order to reduce the power consumption.
Shutter
When the drying time is finished, before the operator is allowed to enter the boot, you must be sure that:
1. The air in the booth has been refreshed;
2. The temperature is lower than a limit. So that you need a profile like the one below:

Ascon Tecnologic - K Series - ENGINEERING MANUAL - PAG. 24
Application example 2: Edge banding machine with glue tank (for wood).
At working temperature the hot melt rapidly oxidizes and runs down from the “dispenser”.
For this reason, when the machine does not work for a certain time, it is suitable to move the temperature of the dispenser to a lower value (idle tempeature value).
In this cases the configuration is the following:
Out 1 = h.reg (heating output);
Out 2 = AL (alarm used to enable the dragger); diF.1 = P.run (dig. input 1 used for program Run/Restart);
Pr.F = S.uP.S (start at Power ON);
Pr.E = cnt (Instrument behaviour at the end of the program execution = continue).
Connect a proximity switch to Dig. Input 1 for panel detection.

7.6 Stand-by mode
This operative mode also deactivates the automatic control but forces the control output to zero.
In this mode the instrument operates as an indicator.
When the instrument is in stand by mode the upper display shows the measured value while the lower display alternately shows the set point and the message St.bY
.
Notes: 1. During stand by mode, the relative alarms are disabled while the absolute alarms are operative or not according to the ALxo (Alarm x enabling during Stand-by mode) parameter setting.
2. If you set stand by mode during program execution, the program will be aborted.
3. If you set stand by mode during self-tune execution, the self- tune function will be aborted.
4. During stand by mode, all functions not related with the control (wattmeter, indipendent timer,
“worked time”, etc.) continue to operate normally.
5. When the instrument is swapped from stand by to auto modes, the instrument automatically starts the alarm masking and the soft start functions.
8. ERROR MESSAGES
Dig In 1
Time
PWR
ON
When a new panel is detected before the end of the first soak time, the program restarts and the set point remains equal to Pr.S1.
If no panel is detected, the instrument goes to Pr.S2 (idle temperature) and remains there until a new panel arrives.
7.5 Manual Mode
This operative mode allows you to deactivate automatic control and manually program the output power percentage that is to be applied to the process.
When the instrument is in manual mode, the upper display shows the measured value while the lower display alternately shows the output power (preceded by H for heating action or C for cooling action) and the message oPLo (open loop).
When manual control is selected, the instrument starts to operate with the same power output as the last one supplied by automatic mode and can be modified using the and
buttons.
In case of ON/OFF control, 0% corresponds to the
“deactivated output status” while any value different from 0 corresponds to the “activated output status”.
As in the case of visualization, the programmable values range from H100 (100% output power with reverse action) to C100 (100% output power with direct action).
Notes: 1. During manual mode, the absolute alarms are operative while the relative alarms are disabled.
2. If you set manual modes during program execution, the program will be aborted.
3. If you set manual modes during self-tune execution, the self- tune function will be aborted.
4. During manual mode, all functions not related with the control (wattmeter, indipendent timer,
“worked time”, etc.) continue to operate normally.
8.1 Out of range signals
The upper display shows the OVER-RANGE and UNDER-
RANGE conditions with the following indications:
Over-range Under-range
The sensor break will be signalled as an out of range:
Note: When an over-range or an under-range is detected, the alarms operate as in presence of the maximum or the minimum measurable value respectively.
To check the out of span Error condition, proceed as follows:
Notes: 1. Check the input signal source and the connecting line.
2. Make sure that the input signal is in accordance with the instrument configuration. Otherwise, modify the input configuration (see Chapter 5).
3. If no error is detected, send the instrument to your supplier to be checked.
