Before working on electrical systems, switch the power switch to "0" and disconnect the
power cord!
Even with the power switch off, some parts in the furnace may carry voltage!
Work on the electrical system may only be done by a trained person!
The furnace and switching system have been preset by the Nabertherm company. If
required, a process-dependent optimization must be carried out in order to achieve the best
possible control behavior.
The temperature curve must be modified by the user so that the load, furnace or
surrounding are not damaged. Nabertherm GmbH assumes no guarantee for the process.
Note
Before working on the program-controlled grounding receptacle (optional series L, HTC,
N, HL) or the device connected to it, always turn off the furnace and disconnect the power
cord.
Carefully read the operating manual of the controller in order to avoid operation mistakes
or malfunction of the controller/furnace during operation.
The controller has a series of electronic safety systems. If a fault occurs, the furnace
automatically shuts off and a fault message appears in the LCD display.
Note
For more information, please see Chapter "Faults - fault messages"
Warning! General Hazards!
The Operating Instructions must be followed prior to switching on the furnace.
The power switch/control current switch is located below or next to the keyboard block.

5.1 Program Entry with/without Gradient as of Version 3.xx
As of controller version 3.xx you can enter ramps either as gradients (e.g. 120°C/h) or using
the "time and target temperature" combination.
Turn the controller off and on again briefly to be able to read the version number.
The input mode can be changed on a user-specific basis in the configuration in support of
the process specification. To change the input mode, see "Configuration"
The mode configured can be seen during program input in a segment, e.g. "time 1", as
follows:
For "time and set temperature" input, only °C/°F or the time h is displayed as the input
unit. For gradient input, °C/°F and h appear together in the display as the unit. The
maximum gradient is 6000°C (fast heating)

5.2 Program Starting Behavior for warm Furnaces as of Controller Version 3.xx
If the furnace temperature c at program start is higher than the set temperature d of the
first segment "T 1", the program start is delayed until the furnace chamber temperature
cools to a value of T1 + 10 °C e. That is, segment "Time 1" is skipped and the program
start occurs in the following segment "Time 2".

For the automatic operation of the furnace, before starting the controller a temperature
characteristic must be configured which describes the desired temperature behavior. This
configured temperature behavior is also called a heating program.
Each heating program for the B 130 and C 280 has two ramps, one holding time, and one
cooling ramp.

T1
waittime 3 time 4time 2time 1
T3
Fig. 13: Program graphic, B 130/C 280
−In the ramps, a segment temperature "T" and a segment time, "time 1" and "time
2" define a linear temperature increase (slow heating).
− In the holding time, "time 3"determines how long the temperature value
configured in "T 2" should be held.
− In the cooling time, the natural cooling can be slowed using the rate set in "T 3"
and "time 4". If there is no specification in "T 3" and "time 4", the
program is already terminated after "time 3" has elapsed.
Program Entry
Using the paging key
you can enter input mode. Every push selects the following
segment or time value. The selected value is displayed with the blinking LED for either "T"
or "time".
- set gradient specifications with °C/hr:min or °F/hr:min
If a value should be changed, you can set it with the

key down for a longer time, the value changes in steps of 100.
key.
Times are entered in hours and minutes, e.g. 6 hr and 30 min as 06:30.
For holding times, an entry of 99:59 means program execution will continue forever.
When input is complete, the program can be started (see Starting the program).
If ramps contain the time entry 00:00, the controller attempts to reach the temperature value
stored in "T" as quickly as possible
If no key is pressed for 60 seconds, the display automatically returns to the display of
temperature. Changed settings are initially only buffered. If a changed or new program
should be permanently stored in the controller for more frequent use, see "Saving
Programs".
Note
Not all segments have to be programmed. For segments which are not needed, the
temperature and time values must be set to "0". The controller then automatically ends the

waiting time ("wait") can be programmed.
To select the waiting time, press the
Times are entered in hours and minutes, e.g. 6 hrs and 30 min as 06:30, i.e., when a heating

6.4 Programming Extra Functions
With controllers of types "C" and "P", up to two optional extra functions "Extra 1" and
"Extra 2" can be turned on or off in the segments depending on the program
Extra functions are, for instance, exhaust air flaps, fans, solenoids, or optical and acoustic
signals, which have been included in the furnace (if applicable, see additional operating
instructions for extra functions)
These extra functions can be specified during program entry in all segments, e.g. "time 1",
by selecting the "Extra 1" or "Extra 2" key.
That is, when the controller processes the programmed segment, the extra functions are
automatically turned on and then turned back of in the next segment, for instance.
Programming of extra functions is done during program entry.
The desired segment must be selected as described in "Entering programs/wait time", so
that the corresponding LED, e.g. "time 1", is flashing.
If the "Extra 1" or "Extra 2" key is now pressed, the extra function is specified for this
segment, and in the display the status field "REL 1" lights up for "Extra 1" and/or "REL 2" for "Extra 2". During program execution, the programmed extra function is
automatically turned on during this segment.
To turn off the specification of an extra function, press the corresponding "Extra" key
again – in the display, the status field "REL 1" or "REL 2" disappears – the extra function
is now no longer turned on. Both extra functions can also be activated at the same time.

, programmed extra functions are indicated in
each segment ("time" LED flashing) with the status fields "REL 1" or "REL 2" in the
display – if the status fields do not light up, the extra functions are not specified.
Note
The programming of extra functions is saved along with storage of heating programs!

6.5 Programming Extra Functions in "T3" (C 280 only)
When programming extra functions in the program value "T3" (C 280 only), the extra
function stays turned on after conclusion of the program, for instance in order to continue
cooling the furnace with a cooling fan.
Extra functions which are automatically turned on during program execution by "T3" must
be turned off by hand if necessary.

6.6 Turning Extra Functions in Program Execution on and off by Hand
Extra functions can be turned on or off during a started program, for the active segment or
after termination of the program, by pressing the corresponding "Extra" key.
If an extra function is turned on during a running program, it remains on until the programspecific segment transition to the following segment occurs.
Changed settings are initially only buffered. That is, buffered programs are overwritten
once a different program is started. If a changed or new program should be permanently
saved in the controller for more frequent use, it can be saved to a permanent program slot as
follows:
Press the save key
The number can be changed to the desired program number using
The program can now be called up from this storage slot at any time (see Program start)
Note
Existing heating programs already saved in a storage slot will be overwritten with no
message or warning. Saved heating programs are still retained after the controller is turned
off. Configured waiting times are not saved. They must be reentered before each process!
The controller automatically returns to the display of the furnace temperature after about 10
seconds when you save without pressing the save key
buffered in this case.
The following programs are preconfigured and can be started directly.
"Baking" refers to the baking of clay, while "glazing" refers to the baking of glazes.
Note
In any case, note the specifications and instructions of the raw material manufacturers,
which may make it necessary to change or adapt the preconfigured programs. It cannot be
guaranteed that optimum results can be obtained with the preconfigured programs. The
configured factory programs can be overwritten for your own purposes (see Setting
programs/wait time).

Note
For furnace models with lower maximum temperatures, the programs listed above are
adapted at the factory to the maximum temperature of the furnace.
Check the heating program called up before starting it, to be sure that it is the right heating
program.
As of version 3, heating programs are reloaded after program termination.That is, the
heating program can be started after a process without having to reenter it. Turn the
controller off and on again briefly to be able to read the version number .
After a heating program is entered or called up, it can be started with the
As of version 3: if the furnace temperature at the starting time is higher than the
temperature specified in "T 1", the controller first waits until the temperature of the warm
furnace has fallen to the first segment temperature T1, and only then does it start the rest of
the program's execution. (See also Chapter "New functions of the Nabertherm controller").
For a cold furnace, the heating program is started immediately.
If the heating program has been started, during program execution the LED of the active
segment "time 1 – time 4" lights up. The controller regulates the configured temperature
profile completely automatically and the status field "heat" lights up in the heating cycle.
If the waiting time is set, the LED "wait" first lights up and the display counts down the
remaining waiting time. The status field "heat" only lights up after program start in
segment "time 1" if the heater is turned on. After conclusion of the last segment, the heater
is turned off and the program terminates. In the display, the end of the program is indicated
with the message "end".

8.2 Setting and Displaying the Date/Time on the P 330
The P 330 has a real time clock that is set at the factory. The time of day can be displayed
by pressing the
follows: The clock is set using a numerical combination of the day of the week and the
time. The setting of the day of the week corresponds to the first digit of the numerical
combination. Each day of the week has its own number.
1=Mon, 2=Tue, 3=Wed, 4=Thu, 5=Fri, 6=Sat, 7=Sun.
Entry of the time of day must then be carried out with the last four digits of the combination

This clock is a real-time clock, that is, even when the controller is turned off, the time is
retained using a built-in battery. The lifetime of the battery is about 3 years. When the
battery is replaced, the saved data (set time) is lost. For the battery type, see the chapter
"Technical data".
The time can only be entered and displayed in 24-hour mode, that is, a display of 12:00
AM/PM is not possible. After the time is set, the controller is fully ready for operation.

P 300/P 310
Each of the 9 heating programs for the P 300/P 310 has 20 ramps and 20 hold times (40
segments in all) which are connected together with the segment blocks A – I.
− In a ramp, a segment temperature "T" and a segment time, e.g. "time 1", define a
linear temperature increase (slow heating).
− In a holding time, e.g. "time 2", it is configured how long the temperature value
configured in "T 1" should be held.

8.6 Programming Extra Functions
With controllers of types "C" and "P", up to two optional extra functions "Extra 1" and
"Extra 2" can be turned on or off in the segments depending on the program
Extra functions are, for instance, exhaust air flaps, fans, solenoids, or optical and acoustic
signals, which have been included in the furnace (if applicable, see additional operating
instructions for extra functions)
These extra functions can be specified during program entry in all segments, e.g. "time 1",
by selecting the "Extra 1" or "Extra 2" key.
That is, when the controller processes the programmed segment, the extra functions are
automatically turned on and then turned back of in the next segment, for instance.
Programming of extra functions is done during program entry.

key. Press again to select or correct the wait
The desired segment must be selected as described in "Entering programs/wait time", so
that the corresponding LED, e.g. "time 1", is flashing.
If the "Extra 1" or "Extra 2" key is now pressed, the extra function is specified for this
segment, and in the display the status field "REL 1" lights up for "Extra 1" and/or "REL 2" for "Extra 2". During program execution, the programmed extra function is
automatically turned on during this segment.
To turn off the specification of an extra function, press the corresponding "Extra" key
again – in the display, the status field "REL 1" or "REL 2" disappears – the extra function
is now no longer turned on. Both extra functions can also be activated at the same time.

8.7 Turning Extra Functions in Program Execution on and off by Hand
Extra functions can be turned on or off during a started program, for the active segment or
after termination of the program, by pressing the corresponding "Extra" key.
If an extra function is turned on during a running program, it remains on until the programspecific segment transition to the following segment occurs.
Changed settings are initially only buffered. That is, buffered programs are overwritten
once a different program is started. If a changed or new program should be permanently
saved in the controller for more frequent use, it can be saved to a permanent program slot as
follows:
Press the save key
The number can be changed to the desired program number using the numerical block
The program can now be called up from this storage slot at any time (see Program start)
Note
Existing heating programs already saved in a storage slot will be overwritten with no
message or warning. Saved heating programs are still retained after the controller is turned
off. Configured waiting times are not saved. They must be reentered before each process!
The controller automatically returns to the display of the furnace temperature after about 10
seconds when you save without pressing the save key
Check the heating program called up before starting it, to be sure that it is the right heating
program.
As of version 3, heating programs are reloaded after program termination.That is, the
heating program can be started after a process without having to reenter it. Turn the
controller off and on again briefly to be able to read the version number .
After a heating program is entered or called up, it can be started with the
As of version 3: if the furnace temperature at the starting time is higher than the
temperature specified in "T 1", the controller first waits until the temperature of the warm
furnace has fallen to the first segment temperature T1, and only then does it start the rest of
the program's execution. (See also Chapter "New functions of the Nabertherm controller").
For a cold furnace, the heating program is started immediately.
If the heating program has been started, during program execution the LED of the active
segment "time 1 – time 4" lights up. The controller regulates the configured temperature
profile completely automatically and the status field "heat" lights up in the heating cycle.
If the waiting time is set, the LED "wait" first lights up and the display counts down the
remaining waiting time. The status field "heat" only lights up after program start in
segment "time 1" if the heater is turned on. After conclusion of the last segment, the heater
is turned off and the program terminates. In the display, the end of the program is indicated

Extra functions can be turned on or off during a started program, for the active segment or
after termination of the program, by pressing the corresponding "Extra" key.
To interrupt program execution only temporarily, for instance to open the furnace door for
removal or addition of material, press the "pause"
the heating is still turned off, but the program is not reset (regulation data is retained).
The program is continued with the "start/stop" key
the elapsed time in that segment into account.
If the furnace door is opened without the pause function, the controller immediately reacts
to the temperature drop and starts to heat immediately after the door is shut – the result can
be an overcompensation in the furnace chamber temperature (see also "Safety" in the
furnace operating instructions).
The key can be used to adapt the power of two heating circuits individually to the
process. The controller has two heater outputs whose ratio to one another can be adjusted
by selectively reducing the two output lines. At delivery, both heating outputs are set to
100% output power.

1) 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!
2) 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.
3) 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! Since the configuration of the output power is process-dependent, these settings can
be saved directly in the heating program. First enter the heating program as described, and
then press the
key to specify the relationship between heating outputs. By saving the
heating program, the entire programming including the configured output power can be
assigned to a program memory (see also "Saving Programs"). The settings for the output
power can also be controlled or changed at any time by pressing the
key. If there is no
other input for 30 seconds, e.g. with the numerical block

The Eurotherm 2132i over-temperature limit controller monitors the furnace chamber
temperature using an independent measurement circuit. If the furnace chamber temperature
rises above the configured value (generally Tmax + 30°C/86°F), the heater is turned off by
a safety fuse to protect the furnace – "FSH" alarm flashes on the over-temperature limit
controller.
If the temperature falls back below the configured value, it must be acknowledge for
operation to resume. To do this, the keys
and ↺ must be pressed simultaneously on
the over-temperature limit controller in order to enable the heater again.
A temperature selection monitor (option for melting furnaces), unlike the temperature
selection limiter, can turn the heating back on after it exceeds the limit. No
acknowledgment is necessary.
Note
The overtemperature limiter and overtemperature selection monitor (optional) must be
checked for proper functioning at regular intervals!
Particular settings which influence the operating behavior of the controller are performed in
the configuration. The configuration is divided into two access levels which can be opened
with different passwords.
For the calculation of electrical power consumption in kW/h in the info menu, you must
enter the furnace power from the type plate. The setting is generally already made by
Nabertherm.
If this is not the case, select the parameter "PF"in the configuration level and enter the type
plate power x 10 with or the key block and confirm with the save key .
Example: furnace power 3.6 kW * 10 = "36" should be entered.
The regulation parameters of the controller are already set at the factory for the optimum
regulation of the furnace. If the regulation behavior is still not sufficient for your process,
the regulation behavior can be improved using auto tune.
The controller has four different parameter sets which are already configured for different
furnace models. The configured parameter set can be seen in parameter "PA" (see also
Configuration). When performing auto tune, the regulation parameters of the selected
parameter set are determined and stored using a special measurement procedure.
Start the auto tune process only with a cooled furnace (T < 60°C), since otherwise incorrect
parameters will be determined for the regulation segment. On the program input level first
enter a value for "T1" at which the temperature is to be optimized. Set all times "time" to
"00:00"n.
In configuration level 2, select parameter "tu", set it to "1", and confirm with the
key.
This will start the auto tune and "tune" will alternate with the furnace temperature in the
display. Once the optimization is complete, the status field "end" will show in the display.
The parameters determined are stored by the controller into the parameter set for the
corresponding temperature range.
Auto tune is always performed at about 70% of the value set in "T1" in any case, to avoid
destruction of the furnace, for instance when optimizing the maximum temperature. Auto
tune may take more than 3 hours for some models, depending on the furnace type and
temperature range. The regulation behavior may be degraded in other temperature ranges
after an auto tune! Nabertherm assumes no liability for damage caused by manual or
automatic changes to the regulation parameters (see also Temperature-dependent parameter
sets).
Note
Perform an auto tune, if necessary, for all temperature ranges.
All controllers can be equipped with a RS-422 data interface, which is optionally
implemented with a 9-pin D-Sub connector. This interface can be used to send or receive
both control functions and archival data. Data exchange is indicated by the "com" (PC
communication) indicator in the display.
The interface is immediately ready for operation; e.g for the Nabertherm furnace
monitoring software "Controltherm MV"
When operating multiple controllers/furnaces on a data network, the interfaces must be set
to different addresses and changed if necessary (see Setting the interface address).
Note
If the data connection line between the furnace and the PC or notebook must be longer than
20m, an optionally available interface power supply (order no. 540100193) may be
necessary to avoid communication errors.
If the Nabertherm furnace monitor package "MV-Controltherm" is not used, the RS422
interface must be equipped with an additional +5 volt power supply. The power supply is
needed by the galvanically isolated driver components of the controller. For this purpose,
for instance, an external interface switching power supply for the 9-pin D-Sub plug
connector can be ordered (order number 540 100 193).

Power failure Appears after power restored
Fault messages can be reset by turning the power switch off and back on. Leave the unit switched off for at least 5
seconds. If the fault message no longer occurs within a minute after power is turned on, the controller is ready to
operate. If there is another fault message, contact Nabertherm service. Ventilation motors (if present) remain on even in
case of a fault. The heater is always turned off.
