The Nabertherm warranty conditions or warranty services regulated in the individual
contracts apply with regard to the warranty and liability. However, the following also
additionally applies:
§
Warranty and liability claims in the event of personal injury and material damage are out of
the question if these are attributable to one or more of the following causes:
− Each person involved in operating, installing, maintaining or repairing the system
must have read and understood the operating instructions. No liability is accepted
for damage and malfunctions arising from nonadherence to the operating
instructions.
− Improper use of the system.
− Improper installation, commissioning, operation and maintenance of the system.
− Operation of the system with defective safety systems or improperly installed or
nonfunctional safety and protective devices.
− Nonadherence to the notes contained in the operating instructions regarding the
transport, storage, installation, commissioning, operation, maintenance and setup
of the system.
− Unauthorized system design changes.
− Unauthorized operating parameter changes.
− Unauthorized parameterization, setting and program changes.
− Original parts and accessories have been designed especially for Nabertherm
furnace systems. Only use original Nabertherm replacement parts. Otherwise, the
warranty will be void. Nabertherm assumes no liability for damages resulting from
use of nonoriginal parts.
−Catastrophes due to the effects of foreign bodies and force majeure.
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.
Stop running heating programs before turning off the furnace with the power switch.
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.

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.

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 the program sequence, 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. Extra function 2 is no longer available with this function.

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.

5.1 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)

Note
The unit of time for the gradient input is preset to hours (h) and cannot be changed to
minutes.
Example: 100°C/h
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".

Time 1Time 2
Fig. 12: 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.
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".
