When the program starts, the highest temperature that is set in the program is determined. If, during the program, the furnace is 50/122 °C/°F hotter than the highest program temperature, the controller switches the heating and the safety relay off and an error message is displayed.
Pre-set function with forced convection furnaces: When a program is started on the controller, the air circulation motor starts. It remains in operation until the program is finished or stopped and the furnace temperature has fallen below a set value (e.g., 80/176 °C/°F).
The kWh counter calculates the power theoretically consumed over the time the heater is turned on for a heating program at nominal voltage. However, there may actually be deviations: If the voltage is low, the power consumption displayed will be too high, and for a higher voltage the power consumption displayed will be too low. Aging heating elements may also cause deviations.

10.7 What is a Holdback?
A holdback is a temperature band around the program setpoint. Should the actual value drift outside this band the holdback function will pause the setpoint adjuster and remaining time and maintain the current setpoint value for as long as necessary for the actual value to return within the temperature band.
The holdback cannot be applied if the processes have to be completed following a precise time specification. The delay of a segment by a holdback is not acceptable, for example, when the actual value approaches the setpoint slowly or there are delay effects in multizone controls/charge controls.
Holdback only affects the master zone in “Auto” and “Manual” modes. The other control zones are not monitored. With “Extended” holdback, the selected control zones are monitored. This function is not yet available in the VCD software.
The holdback monitoring is only possible in dwell times.
In “Auto” and “Manual” modes, for charge control the charge thermocouple is the control zone for the holdback.
There are 3 holdback modes:
Holdback = AUTO: There are no effects of a holdback on the program except when switching over from ramps to dwell times. Here, the controller waits for the dwell time temperature to be achieved. The program waits at the end of a ramp for the dwell time temperature to be reached. Once the dwell time temperature is reached the controller jumps into the next segment and the processing is continued.
Holdback = EXTENDED (only P570/P580): When ramps switch over to hold times, the controller waits until the hold time temperatures are reached in all selected control zones. When the hold time temperature is reached in all selected zones, the controller jumps to the next segment and processing continues. If a control zone leaves the entered holdback band after it has been reached, a warning message is generated referring to the zone leaving the positive or negative band. Note: The evaluation that a temperature has entered this band is reset if there is a power failure. During a power failure, there is no message that temperatures are out of the band. Note: If a thermocouple in this band that is used to monitor the extended holdback breaks, in addition to the warning about the breakage, another warning is output: “Out of undertemperature band”.
Note: The charge measuring point should be monitored only in programs with active charge control. Otherwise, the program cannot run correctly. Note: The cooling measuring point should be monitored only in furnaces with a separate cooling thermocouple. Otherwise, monitoring cannot be carried out correctly.
Holdback = MANUAL: A tolerance band can be entered for each hold time. If the temperature of the master zone (or the charge thermocouple with charge control) leaves the band, the program is stopped (Hold). The program continues when the master zone is in the band again. If 0 °C is entered as the band, the program is not stopped and is timecontrolled, regardless of the temperatures that are measured. This band does not work in ramps and prolongs the hold time when the temperature leaves the band.
If the value entered is “0”, the program works “purely time-controlled”. No influence of the program takes place.
46

Paramter Entry:
In program input, operators can set the holdback to “Auto”, “Manual” or “Extended” in the start segment (program-wide parameters).
10.8 Changing a Running Program
A running program can be changed without ending it or changing the saved program. Remember that no past segments can be changed unless you again go to the desired segment, using the function [SEGMENT JUMP].
Note: With a manual segment leap it may happen that more than one segment is skipped per leap. This depends on the current temperature of the furnace (automatic application of actual value).
Note Changes made to a running program remain only until the program is finished. The changes (including hold function) are deleted when the program is finished or if there is a power outage during the program.

If the current segment is a ramp, the current actual value after the program change, is accepted as a setpoint and the ramp is continued at this point. If a current dwell time is changed, then a change in the running program has no impact. Only a manual segment jump into this segment results in the execution of a change in the dwell time. The changes on following dwell times are executed without any restrictions.

The following steps must be performed to change an active program:

Change current program

SUPERVISOR

Procedure

Operation Display

Comments

Select [Furnace]

Select [Change Active Program]

This can be selected only when a program is running. The administrator can block access to this function for supervisors in the settings.

When a program is active only individual segments can be changed. Global parameters such as the holdback operating mode and charge control cannot be changed.
After saving the change, the program is continued at the time of the change.

10.9 Performing Segment Jumps

Besides changing a program, it is also possible to jump between the segments of a running program. This can make sense if, for example, a dwell time needs to be shortened.

Note: With a manual segment jump it may happen that more than one segment is bypassed per step, even if this was not intended. This depends on the current temperature of the furnace (automatic application of actual value).

The following steps must be taken to execute a segment step:

11.2 Measurement Range Calibration
Note This correction function corresponds to “instrument correction offsets” according to AMS 2750F.
The measurement range from the controller to the thermocouple can exhibit measurement errors. The measurement range consists of the controller inputs, the measurement wires, sometimes terminals and the thermocouple. If you discover that the temperature value on the controller display no longer agrees with the value of a comparison measurement (calibration), this controller offers the option of an easy matching of the measurement values for each thermocouple. By entering up to 10 base points (temperatures) with the relevant offsets these temperatures can be matched very flexibly and precisely. When an offset of a grid point is entered, the actual value of the thermocouple and the entered offset are added. Examples: · Adaptation using a comparative measurement: The control thermocouple outputs a
value of 1000 °C. Calibration measurements near the control thermocouple return a temperature value of 1003 °C. By entering an offset of “+3 °C” at 1000 °C, this temperature is raised by 3 °C and the controller, then also returns a value of 1003 °C. · Adaptation using a transducer: Instead of the thermocouple, a transducer supplies the measurement range with an actual value of 1000 °C. The display outputs a value of 1003 °C. The deviation is “-3 °C” from the reference value. Hence, the offset that must be entered is “-3 °C”. · Adaptation using a calibration certificate: On the calibration certification (for example for a thermocouple) there is, at 1000 °C, a deviation of “+3 °C” from the reference value. The correction is “-3 °” between the display and the reference value. Hence, the offset that must be entered is “-3 °C”. · Adaptation using a TUS measurement: During a TUS measurement, a deviation of the display from the reference band of “-3 °C” is determined. Here, the offset that must be entered is “-3 °C”. Caution The thermocouple calibration certificate does not take into account the deviations of the measurement range. Deviations of the measurement range must be determined by a measurement range calibration. The two values are added together to produce the correction values that need to be entered.
Caution Please observe the instructions at the end of the section.
49

The setting function in this instance follows specific rules:
· The values between two support points (temperatures) are linearly interpolated. That means that a straight line is projected between the two values. The values between the supporting points are then on this line.
· The values below the first support point (for example, between 0 and 20 °C) are located on a straight line that is connected (interpolated) with 0 °C.
· Values above the last supporting point (for example >1800 °C) are project further with the final offset (a final offset at 1800 °C of +3 °C is also used at 2200 °C)
· Temperature inputs for the support points must be in ascending order. Support points that follow gaps (“0” or a lower temperature for a support point) are ignored.

11.3 Control Parameters

Control parameters define the behavior of the controller. For example, the control parameters influence the speed and accuracy of control. This allows users to adjust the controls to suit their particular requirements.
This controller provides a PID controller. The output signal of the controller consists of 3 parts:

· P = proportional portion

· I = integral portion

· D = differential portion

Proportional Portion

The proportional portion is a direct reaction to the difference between the setpoint and the actual value of the furnace. The larger the difference, the larger the P-portion. The parameter that influences this P-portion is the parameter “Xp”.
Here the following applies: The larger the “Xp”, the smaller the reaction to the deviation. So it acts inversely proportional to the control deviation. At the same time, this value describes the deviation, for which the P-portion rises to = 100 %.

Example: A P controller should, for a control deviation of 10 °C, output a power of 100 %.

Xp is therefore set to “10”.

[%]

100%

[°]

Integral Portion

The integral portion grows as long as a control deviation is present. The speed at which this portion grows is determined by the constant TN . The bigger this value is, the more slowly the I-portion increases. The I-portion is set using the parameter [TI] unit: [Seconds].
Differential Portion

The differential percent reacts to the change in the control deviation and works against it. If the temperature in the furnace approaches the setpoint, the D-portion acts against this approach. It “dampens” the change. The D-portion is set using the parameter [TD] unit: [Seconds].

The controller calculates a value for each of these percentages. Then all three percentages are added together and the results is the power output of the controller for this zone in percent. Whereby, the I- and D-portions are each limited to 100 %. The P-portion is not limited.

Caution
The I-portion is only enlarged until the P-portion has reached its maximum value. From then on the I-portion is no longer changed. In certain situations, this can prevent major overshooting.

Note
The control parameters are set in the same way as for Nabertherm controllers B130/B150/B180, C280 and P300-P330. If a controller is replaced, the controller settings can be transferred and then be optimized. Series 400 controllers (B400, B410, C440, C450, P470, P480) use the same control parameters as Series 500 controllers (B500, B510, C540, C550, P570, P580).

11.4 Properties of the Controls
This section describes how to adjust integrated controllers. Depending on the features, controllers are used for zone heating, charge control and controlled cooling.

11.4.1 Smoothing
A heating program usually consists of ramps and dwell times. Overshooting is a likely possibility when the program progresses from one segment to the next. In order to dampen this tendency to overshoot, the ramp can be “smoothed” just prior to the transition into th dwell time.

11.4.2 Heating Delay

Set heating delay Procedure Select [Settings]

If a furnace is loaded hot and with the door open, the cooling of the furnace will result in intensive reheating and overshooting after the door has been closed.
This function can delay the switching on of the heating so that the heat stored in the furnace first raises the temperature in the furnace again. If the heating switches on again after the delay time, the heating need not reheat the furnace as much and overshooting is avoided.

Caution
In order to be able to use this function the door switch signal (“Door closed” = “1” signal) must be connected to an input of the controller module. The setting of the corresponding input can only be performed in the service level and, hence must be set before the controller leaves the factory.

11.4.3 Manual Zone Control

Display A1 in % A2 in %

It is possible that for furnaces with 2 heating circuits that do not have their own multi-zone control, different output powers are needed.
Using this function you can individually adapt the power of two heating circuits to the process. The controller has two heating outputs whose ratio in relation to each other can be set differently by the optional reduction of one output power. When shipped from the factory, both heating outputs are set to 100 % output power.

The setting of the ratios of the two heating circuits and their output powers are shown in the following table:

10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 200

Example:

At the setting “200”, the furnace is heated only through output 1 (A1), for instance for a furnace for fusing applications, if only the ceiling heater is to be used and the side or floor heater is to be turned off. Note that when operating with reduced heating power, the furnace may no longer be able to reach the maximum temperature specified on the type plate!
At setting “100”, the furnace is operated with both heat outputs without reduction, for instance for an even temperature distribution when baking clay and ceramics.
At setting “0”, output 1, for instance, the ceiling heater in fusing furnaces, is turned off. The furnace is heated only through the heater attached to output 2 (A2), e.g. the side and floor (see the furnace description). Note that when operating with reduced heating power, the furnace may no longer be able to reach the maximum temperature specified on the type plate!
The settings can only be saved globally and not program-dependent.

Caution
Consult the furnace directions to determine which output (A1) (A2) is responsible for which heating range. For furnaces with two heating circuits, Output 1 is always the upper and Output 2 is always the lower heating circuit

11.4.4 Integrating the actual value as setpoint for the program start
Application of the actual value is a useful function to shorten heating up times. Normally, a program starts at the start temperature that was entered in the program. If the furnace is below the start temperature of the program, the specified ramp is still started and the furnace temperature is not applied. When deciding the temperature at which it will start, the controller always bases its decision on which temperature is higher at that time. If the furnace temperature is higher, the furnace starts at the current furnace temperature; if the start temperature set in the program is higher, the program starts with the temperature that is set there. This function is switched on when the controller is delivered.
With segment leaps actual value application is always activated. Therefore, segments may be skipped with segment leaps.
Example:
A program with a ramp from 20 °C to 1500 °C is started. The furnace still as a temperature of 240 °C. With activated take over actual value the furnace does not start at 20 °C but at 240 °C. The program can be substantially shortened.
This function is also used for segment steps and program changes in a running heating program.

The following steps must be performed to activate or deactivate the automatic take over value:

11.4.5 Controlled Cooling (option)
A furnace can be cooled in different ways. Cooling can be controlled or uncontrolled. Uncontrolled cooling takes place with the cooling fan set at a fixed speed. Controlled cooling also processes the temperature of the furnace and can set the correct cooling level at all times with variable speed control or flap settings without the intervention of the operator. Controlled cooling is necessary if the furnace is to use a linear cooling ramp that is faster than the natural cooling of the furnace. This is possible only within the physical limits of the furnace.
This controller is suitable for controlled cooling such as this. In a heating program, controlled cooling can be switched on and off for specific segments. In addition to activating a cooling function, the exhaust air flap must be opened permanently via an extra function or a switch setting. A description of the extra functions and the functionalities or other operating elements can be found in the separate switchgear description. Controlled and uncontrolled cooling cannot be activated at the same time. Using these functions is under the assumption that cooling is prepared in the furnace and activated in the controller ([SERVICE] menu). Otherwise, this option cannot be selected in program input. We recommend that cooling be activated only in a cooling ramp (decreasing setpoint).
The controlled cooling is realized with the help of a tolerance band around the setpoint (see the figure below). This tolerance band consists of 2 limit values that enclose a monitoring range.
This range is uses as a hysteresis when switching between heating and cooling. The range should not be too large. A range of 2 – 3 °C has proved to be practical.
If the furnace temperature exceeds the upper band (1), cooling is activated (a fan for example) and all zones of the heating are switched off. If, during cooling, the furnace temperature falls below the lower band (3), the cooling is switched off.

Temperature

If the furnace temperature is below the lower band (3), the heating is reactivated. If, during heating, the furnace temperature rises again above the upper band (1), the heating is switched off completely. If there is a malfunction in the cooling thermocouple during active cooling, the system switches over to the thermocouple of the master zone.
Time 1A = upper band, 1B = setpoint, 1C = lower band, 1D = cooling, 1E = heating Fig. 3: Switching between heating and cooling Note When the switchover from heating to controlled cooling is made, the I and D parts of the controller are also deleted. To observe the control parameters of controlled cooling, please read “Information Menu > Display PID Output”.
For controlled cooling, the thermocouple in the set master zone or a cooling thermocouple connected especially for controlled cooling is decisive (this depends on the furnace model). Documentation thermocouples or thermocouples from additional zones are not considered here. This applies also if charge control is active. If controlled cooling is selected for a program segment, the zone thermocouple is switched to the cooling thermocouple for the complete segment. If no cooling thermocouple is connected, the thermocouple from the master zone is used for controlled cooling. With active controlled cooling with a separate cooling thermocouple, the display in the main overview is switched to the temperature of the cooling thermocouple. This does not apply if charge control is active. In this case, the temperature of the charge thermocouple is displayed. In the process documentation, the cooling temperature (with or without a separate cooling thermocouple) is always recorded parallel to the control thermocouple and the cooling output. The controlled cooling can be parametrized in the [SETTINGS] menu. This is done by performing the following steps:

Behavior in Case of Error
If the cooling thermocouple is defective, the thermocouple in the master zone is used. The temperature in the zone with the defective thermocouple is shown with “– °C”.
A defect is also displayed if no controlled cooling is selected.
11.4.6 Start-Up Circuit (Output Limit)
A temperature control always reacts to a deviation between setpoint and the actual temperature value in the furnace. If this difference is large, the controller attempts to reduce this difference by means of greater heating power. This can lead to damage to the charge or the furnace.
This can have, for example, the following reasons:
· Use a thermocouple with major imprecision in the lower temperature range (for example type B)
· Use of pyrometers that in the lower temperature range do not deliver a measurement value
· Use of thermocouples with heavy-duty protective tubes and, hence, longer delay time
In order to limit the power peaks of the heating system in the lower temperature range in these cases, you are provided with the function “Start-Up Circuit/Output Limit”. With this function you can limit the controller output for the heating to a specified temperature [LIMIT TEMPERATURE] to a specific output [MAX POWER] . Independent of the set setpoint, the furnace does not heat up with more power than in the startup circuit.

The following steps must be performed to set the startup circuit/power limit:

The startup circuit analyzes the following thermocouples:
· For a single-zone control: The control thermocouple is monitored
· For a single-zone control with charge control: The control thermocouple is monitored
· For a multi-zone control: All the zones are monitored individually. If a zone is below the limit temperature, the output power of the corresponding zone is limited correspondingly.
· For a multi-zone control with charge control: In this combination, the startup circuit behaves like a mult-zone controller.
11.4.7 Self Optimization
The behavior of controllers is determined by control parameters. The control parameters are optimized to a specific process behavior. To allow furnace operation to be as rapid as possible other parameters are used than those for an operation that is as precise as possible. To simplify this optimization, this controller offers the option of an automatic optimization, self- optimization. This does not replace the manual optimization and can only be used for single-zone furnaces, not multi-zone furnaces.
The control parameters of the controller have already been set at the factory for an optimum control of the furnace. If the control behavior must be adapted for your process, you can improve the control behavior by means of a self- optimization.
The self-optimization takes place in a specific sequence and, in addition, can only be performed, each time, for one temperature [OPT TEMPERATURE]. The optimization of several temperatures can only be performed one after another.
Start the self-optimization only when the furnace is cooled down (T < 60 °C), since otherwise false parameters are calculated for the control section. First enter the optimization temperature. The self-optimization is performed in each case at approx. 75 % of the set

Start auto-tune Procedure Select [Settings]

value to prevent a destruction of the furnace, for example for the optimization of the maximum temperature. For some models, the self- optimization can take longer than 3 hours depending on the type of furnace and temperature range. The control behavior can be worsened by a selfoptimization in other temperature ranges! Nabertherm assumes no liability for damages that are caused by manual or automatic change in the control parameters.
For this reason, check the control quality after autotune by operating the furnace without charge.
Note
Execute the autotune, if necessary, for several temperature ranges. Autotunes in lower temperature ranges (< 500 °C/932 °F) can return extreme values depending on the calculation procedure. Correct these values, as necessary, by a manual optimization. Always check the returned by performing a test run.

The following steps must be performed to launch a self-optimization:

Operation Display

ADMINISTRATOR Comments

Select [Control]

Select [Auto-Tune]

Enter the optimization temperature
Start auto-tune

When this is confirmed, the controller starts to heat the furnace to the set temperature.

If self-optimization was started, the controller heats to 75 % of the optimization temperature at full power. The heating process is then stopped and restarted at 100 % power. This procedure is carried out twice. Self- optimization is then finished.
After the autotune has been completed, the controller ends the heating and enters the calculated control parameters but not yet into the corresponding base point of the control parameters.
To save the calculated parameters, open the autotune menu again and check the parameters. Then you can select the base point in the same menu in which you want to copy the parameters.

11.4.8 Charge Control

The cascade, charge or melting bath control system is a combination of two control circuits which permits the temperature measured directly at the product being treated to be adjusted very precisely and rapidly dependent on the furnace chamber heating. When the charge control is turned on (cascade control) the temperature is measured by an additional thermocouple directly at the charge, for example in an annealing box, and controlled in relation to the furnace temperature.

Operation with Charge Control (cascade control)

When the charge controller (cascade) is turned on, both the charge temperature and the furnace chamber temperature are measured. A setpoint offset is generated for the furnace chamber, corresponding to the amount of the control deviation. This achieves a substantially quicker and more precise temperature control at the charge.

Setpoint charge Setpoint furnace chamber Actual value furnace chamber Actual value charge/tank Setpoint offset

Operation with Charge Control (cascade control) When the charge control (cascade) is switched off only the furnace chamber temperature is measured and corrected. Since the charge temperature in this context has no influence on the regulation, it approaches the program setpoint more slowly.

Setpoint furnace Actual value furnace Actual value charge/bath
As explained in the previous paragraphs, the charge controller influences the furnace chamber controller to compensate the deviation between the thermocouple at the heating elements and the thermocouple at the charge (e.g., in the middle of the furnace). This compensation must be limited so that the furnace does not begin to vibrate. The following parameter can adapted for this purpose: Maximum Negative Output The maximum negative offset that is transferred from the charge controller to the heating controller/zone controller. Hence, the setpoint of the heating zone cannot become smaller than: · Heating setpoint = program setpoint maximum negative offset. Maximum Positive Output The maximum positive offset that is transferred from the charge controller to the heating controller/zone controller. Hence, the setpoint of the heating zone cannot become greater than: · Heating setpoint = program setpoint + maximum positive offset. No I-Portion in Ramps In ramps it is possible that the I value (integral portion of the output) of the charge controller slowly builds up a lasting control deviation. For the transition into the dwell time this cannot fall rapidly enough and the result may be an overshoot. To avoid this effect, a build-up of the I-portion of the charge controllers in ramps can be deactivated. Example: If for the charge setpoint 500 °C is pre-set, the furnace chamber can, for an optimum control, accept a setpoint of 500 °C + 100 °C, i.e. 600 °C. The result is that the furnace chamber can heat up the charge very rapidly. Depending on the process and the charge, it may be necessary to change the offset values. For example, a too sluggish control can be accelerated by a higher offset, or a too rapid control can be slowed down. However, the offset should only be changed after consultation with Nabertherm since the control behavior is largely determined by the control parameters and not by the trim.

Additional Instructions:
· When the charge control is active, the large temperature display of the main overview is switched to the charge thermocouple.
· The error analyses that are part of the charge control (for example, a pulled charge thermocouple), are only activated if the charge control is activated in a running program. If the charge thermocouple has an error, a switchover is made to the master zone thermocouple and an error message is outputted. A program interrupt does not take place.
· The switchover between the control parameters, for example from Support point 1 to Support point 2 conforms with the program setpoint, not with the actual temperature value in the furnace.

· With activated charge control, it is recommended to use the holdback type “Auto” in the program. If extended holdback is used, the offsets that are generated can result in undesired warnings.
Limiting the Offset of the Charge Controller [BLOCK LOWERING]:
Charge control does not directly affect the heating; it influences the heating controller indirectly via an offset on the program setpoint. This offset (output) is simply added to (positive offset) or subtracted from (negative offset) the setpoint. A negative offset is usually permissible only with decreasing (negative) ramps, as otherwise fluctuations would occur.
Certain furnace series (such as tube furnaces) need the option that the negative offset is also active during hold times or heating ramps. Otherwise, it could happen that the program does not go to the next segment.
This release can be granted via the parameter [BLOCK LOWERING] = [NO] in the charge control settings. This adaption should only be performed if it is necessary for the process.

11.4.9 Setpoint Offsets for Zones

With multi-zone furnaces it may be necessary to give the zones different setpoints. Normally, all the furnace zones work with the setpoint that is generated from the heating program. For example, if a zone does not have 600 °C has a setpoint as the other zones do, but instead only 590 °C, this is possible using the “Zone Offset Set Value”.

The following steps must be performed to enter setpoint offsets for one or several zones:

11.8 Configuring the Extra Functions

Besides heating, many furnaces support additional functions such as exhaust- air flaps, fans, solenoid valves, optical and acoustic signal (see, as necessary, addition instructions for the extra functions). For this purpose, each segment offers an opportunity to enter values. How many extra functions are available depends on the furnace design.
With this controller, in the basic configuration, optionally, up to 2, with additional modules, up to 6 extra functions, depending on the program, can be switched on or off in the segments.
Extra Functions Are for Example
· Activating a fresh-air fan
· Activating an exhaust air flap
· Activating a signal lamp
If you want to deactivate or rename individual functions, perform the following steps.

11.10.2

Acoustic Alarm (Option)
The acoustic alarm is one of the possible “reactions” in alarm configuration. The parameters of the acoustic alarm allow the operator to set certain additional properties. Regardless of the configuration, the output where the acoustic alarm is connected can be output constantly, at intervals or with time limits. The acoustic alarm is acknowledged by acknowledging the error message.

Configure alarms Procedure Select [Settings]

Parameters [CONSTANT] [LIMITED] [INTERVAL]

In case of alarm, a continuous alarm signal is generated.
The alarm signal is interrupted after a preset time and, then, remains turned off.
The alarm signal is turned on for a preset time and then turned off for this preset time. This procedure repeats.

The acoustic alarm can be set as follows: Operation Display

11.10.3

Gradient monitoring
Gradient monitoring monitors the rate at which a furnace heats up. If the furnace heats up faster than set in the limit value (gradient), the program is interrupted.
What is decisive for a reliable analysis of the gradients is the time interval in which the gradient is repeatedly recalculated (sample interval). If it is too short, the gradient alarm is sensitive to fluctuations of the control or the furnace and probably will be triggered too soon. If the sampling interval selected is too long this may also have an impact on the charge or the furnace. This is why the right sampling interval must be calculated by trial runs.
In addition to the sampling interval, a delay of the alarm can be activated. For example, a delay of “3” means that only after 3 measurement cycles have been recognized as having excessive gradients does a reaction take place.
In order to avoid faulty measurements in the lower temperature range, a lower limit temperature can be selected for the analysis.
In the case of multi-zone furnaces and furnaces with charge control, always only the master zone (guide zone) is analyzed.

After a gradient alarm, the first sample interval that does not return a gradient exceedance restarts the heating program. The furnace runs again.

The warning for the gradient alarm can be deleted by switching the controller off and on again.

The following steps must be performed to set the gradient monitoring:

The delay defines the number of measurement cycles that take place before the alarm is activated.

Caution
This function contributes to protecting the charge and the furnace. A use for the avoidance of dangerous conditions is not permissible.

11.10.4 Examples of Alarm Configuration
Below is some help to parameterize frequently occurring alarms. These examples are for illustration purposes only. The parameters may have to be adjusted to the specific application: To adjust the alarms, remember to log on as [ADMINISTRATOR].
Example: External error
An external error, e.g. a temperature switch signals an over-temperature by closing a contact. This should result in a program interrupt.

11.11 Network Failure Behavior Settings

In case of a power outage, no heater power remains. Hence, any power outage has an impact on the product in the furnace.

The behavior of the controller during a grid power outage has been preset at Nabertherm. But you can always change this behavior to suit your own needs.

There are 4 modes available:

Mode

Parameter

Mode 1

[CANCEL]: If there is a power outage, the program is canceled.

Mode 2

[DELTA T] When the power returns, the program continues if the furnace has not cooled too much [<50 °C/90 °F]. Otherwise the program is canceled.
The program is always canceled below a limit temperature [T min = 80 °C/144 °F].

Mode 3

[TIME] (pre-selection)
When the power returns, the program continues if the power was not out for longer than the set time [max. power outage time 2 minutes]. Otherwise the program is canceled.

Mode 4

[CONTINUE] When the power returns, the program always continues.

Caution After a power outage the program, i.e. the remaining run time of the dwell time, is continued at the same rate. Power outages < 5s are always continued.
