1.2 General
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.
1.3 Safety
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.
2 Operation
2.1 Power switch/control current switch
The power switch/control current switch is located below or next to the keyboard block.
Stop running heating programs before turning off the furnace with the power switch.
2.2 Turning on the controller/furnace
Switch power switch to "I" position. The controller first displays the controller type and
version number and then the temperature display. If the temperature is displayed, the
controller is ready to operate.

All necessary settings for proper function have already been done at the factory.
For the B 130 and C 280, heating programs for baking and glazing (see chapter
"Preconfigured programs for the B 130/C 280") are configured. For the other controllers,
the heating programs must be configured on a process- or user-specific basis.
Note
Some new functions depend on the version number. Turn the controller off and on again
briefly to be able to read the version number.
2.3 Turning off the controller/furnace
Turn off main switch at position "O".
Note
Stop running heating programs before turning the furnace off at the main switch, since the
controller will otherwise generate a fault message when it is turned back on.

4 Features of the Controller
4.1 Functions
1) When the program starts, the highest temperature in the program is calculated. If the furnace is 30°C warmer than the highest program temperature for 3 minutes during program execution, the controller turns off the heating and the safety relay and a fault message appears
2) Preconfigured function for circulation furnaces: Once a program has been started on the controller, the air circulation motor starts. It remains in operation until the program terminates or is interrupted, and the furnace temperature falls back below 80°C.
3) The kW/hr 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.
5 New functions of the Nabertherm controller
5.1 Program entry with/without gradient as of version 3.xx
As of controller version 3.xx, the input of ramps can optionally be performed as a gradient
(e.g. 120 °C/hr) or using combined "time and set temperature" (factory setting C 290:
gradient,other controllers "time and set temperature")
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 time hr:min is displayed as the input
unit. For gradient input, °C/°F and hr:min 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".
Fig. 9: Program start behavior
This program start behavior is permanently programmed into all controllers as of version
number 3.xx and cannot be changed. Turn the controller off and on again briefly to be able
to read the version number.
5.3 Power failure behavior
As of controller version 3.xx the power failure behavior can be configured.
Turn the controller off and on again briefly to be able to read the version number. To
change the power failure behavior, see chapter "Configuration/customer-specific
settings".

6.2 Setting or changing program/waiting time
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.

? In the ramps , a segment temperature "T " and a segment time, "
time 1" and "time

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 "

program is already terminated after "time 3" has elapsed. Program Entry

In the display, the temperature value "T " or time value "time " corresponding to the flashing LED is shown.
temperature or time value.
The display also shows the unit of the value expected: - set temperature values with °C/°F - set time specifications with hr:min
- set gradient specifications with °C/hr:min or °F/hr:min
(Factory setting for C 290 "gradient", other controllers "time and set temperature") Enter time segment 1 Enter temperature 1 Enter time segment 2
Entry of times is done 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
program after the last segment programmed
Waiting time
To start a heating program automatically at at a later time, for instance after a drying
period, a waiting time "wait" can be programmed.
To select the wait time, press the paging key repeatedly until the "Wait" LED flashes.
The entry of times is in hours and minutes, e.g. 6 hrs and 30 min as 06:30, that is, when a
heating program is started, first the wait time elapses and only then does the program start
with segment 1 and heating.
6.3 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.

Fig. 11: Selection of "Extra 1 funktion" in segment "time 1"; LED "time 1" flashes
Fig. 12: In the display, "REL 1" lights up for the selected "Extra 1 funktion"
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!
6.4 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.
6.5 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 program-
specific segment transition to the following segment occurs.
6.6 Saving programs
Changed settings are initially only buffered. That is, buffered programs are overwritten
once a different program is called up. 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:
Fig. 13: Saving a program to program slot no. 9
The program can now be called up from this storage slot at any time (see Program start)
6.7 Preconfigured programs for the B 130/C 280
The following programs are preconfigured and can be started directly.
Baking is suitable for the baking of clay, while glazing is suitable for the baking of glazes.
Note
In any case, note the specifications and instructions of the manufacturer 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).

6.8 Calling programs
Call up saved programs with the P
Fig. 14: Calling heating program no. 9
Note
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 .
6.9 Program Start
After a heating program is entered or called up, it can be started with the start
stop key.
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
