General information

5Features The Controller B 150 is an electronic temperatureregulator with the following features:

The Controller is provided with a number of electronicsafety equipment. If a fault occurs, the furnace switchesitself off automatically and an error message appears onthe LC display. You can find more detailed informationin the chapter Error messages.

Switch mains switch to position I. Type and version ofthe Controller appear on the display. Then the Controlleris ready to operate. All necessary settings for properfunctioning were already made at the factory.

Setting or changing programs/delay timeThe program has a ramp and a holding time: A linear rise in temperature (slow heating) is set in

the ramp via segment temperature T1 and segmenttime time 1.

In holding time 2 you can define how long thetemperature set in T1 is to be maintained. Duringthe program run the holding time can be changed byactuating the key, selecting the time valuetime 2 and keeping the +/- button pressed.

The values can be changed with the +/- key. Byactuating the key repeatedly, the value is changed by1 C (1 F) or by one minute.Keep the key pressed to change the value more quickly.If this key is operated once

Confirm the entry in T or time by actuating the key. If this key is not pressed, the changes arediscarded and the previously set value remains valid.

To ensure that old program values are not retrieved in anewly generated program, you should first call in theprogram 0.

The unit of the expected value C/F or h:mm is shownon the display.Input the time in hours and minutes, e.g. enter 06:30 forsix hours and 30 minutes.Skip values that are not to be changed with .Changed settings are first of all only stored temporarily(please see also Saving programs).

After a program has been input or changed, the modifiedvalues are saved in a volatile memory.If you want to store the program changes permanently,actuate the storage key twice. The program canthen be called from memory location 1.

If the storage key is not pressed a second timewithin 10 seconds the Controller displays againthe furnace temperature. In this case the programis not stored.

Program locations that are already occupied areoverwritten without further notice and can no longer berecovered.

Stored programs remain in the memory even when thesystem is switched off.

Call the stored program with the P key and check theprogram by actuating the button.

After input of a heating program the process can bestarted with start/stop . After the program has been

When a delay time has been defined the diode waitlights up and the remaining delay time is counted downon the display. The status field heat flashes onlywhen the program has been started.

To abort a program press the start/stop key again.The heater is switched off and the status field endflashes.

The program can be aborted at any desired time.

However, it is not possible to abort a program onlytemporarily.

To prevent unintentional or prohibited access to the pro-gram run, the keyboard can be blocked by means of thekey lock after the program has been started.

The key lock can only be released when the Con-troller is switched off and then on again (behaviourduring switching off, please refer to Power failurebehaviour)!

By actuating the info key, the following processinformation can be displayed:

The Controller B150 can be equipped with an RS 422data interface, that is optionally realized via a 9-pin D-Sub plug connection. This interface can be used to sendand receive control functions as well as archive data. Adata transmission is indicated on the display by com(communication with PC).The interface is immediately ready for operation; e.g. forthe Nabertherm furnace supervision software Control-therm (see also Setting of the interface address.)

To operate several Controllers/furnaces on one datanetwork the interface address might have to be changed(see Setting of the interface address).

If the data connection line between the furnace and thePC/notebook is longer than 20 m, communication errorsmay occur if an interface power supply that is availableas option is not used.

Special settings that affect the operational behaviour ofthe Controller are to be made in the configuration menu.The configuration menu is divided into 2 access levelsthat can be called via different passwords.

Keep the Info key pressed and actuate the ----- keybriefly, then release the Info key again. Co 0 isdisplayed and the system is waiting for the password.Actuate +/- to enter the code for the desiredconfiguration level and confirm by pressing the storage key. Scroll the screen with to display theparameters one after the other as described above.

Changed settings must be stored by pressing the storage key. During write operation the value is flashingbriefly on the display.

Changing the control parameters may affect thefunction of the control system considerably.

To calculate the power consumption in kW/h in the infomenu, the furnace performance which is indicated on therating plate must be input. In general these settings werealready defined by Nabertherm. Otherwise selectparameter PF at configuration level 0 and input the

When several Controllers are operated within a datanetwork, different addresses are to be set at the Control-lers.

Select parameter Adat configuration level 0, inputa new addresss (1...99) and confirm by actuating the storage key.

Select parameter Fat configuration level 0, set to1 and acknowledge with .The safety cut-out in the Controller is automaticallyconverted, all the other temperature settings mustsubsequently be changed to F, if necessary.The preset heating programs are always programmed inC and must be adapted manually if the temperatureunits are changed.

The control parameters of the Controllers are already setfor an optimum regulation of the furnace at the factory. Ifthis control behaviour should be inappropriate for yourprocess, you can improve it by automatic optimization.The Controller has four different parameter sets, thatwere preset for different furnace models.

The preset parameter set is indicated in parameter PA(please see also Configuration).When the automatic optimization is carried out the controlparameters of the selected parameter set are determinedand stored by a special measuring method.

Start the automatic optimization only when the furnacehas cooled down (T < 60 C) since otherwise wrongparameters will be determined for the controlled process!

First input a program in which the temperature to beoptimized is programmed in T1. Set all time displaystime to 00:00.

Select parameter tu at configuration level 2, set to1 and confirm by pressing the key. The automaticoptimization is now started and tune and the furnacetemperature appear alternately in the display.When the optimization is finished the status field Endis flashing. The determined parameters are stored by theController in the parameter set for the correspondingtemperature range.

In any case the automatic optimization is carried out atappr. 70% of the value set in T1 in order to preventdestroying the furnace, e.g. when the maximumtemperature is optimized.The automatic optimization can take more than 3 hoursfor some models, dependent on the furnace type and thetemperature range.

The control behaviour may deteriorate in other temperatureranges when an automatic optimization was executed.Nabertherm rejects all liability for damages which arecaused by manual or automatic changes of the controlparameters (please see also Temperature-dependentparameter sets)!

Temperature-dependent parameter setsIf 0 is set in parameter PA, all 4 parameter sets areavailable to control the furnace. The parameter sets arethen divided as follows:Parameter set 1 T = 0 -250 C (0 -482 F)Parameter set 2 T = 251 -500 C (483 -932 F)Parameter set 3 T = 501 -1000 C (933 -1832 F)Parameter set 4 T > 1000 C (>1832 F)

Read out the parameter set selected in PA before youactivate the temperature-dependent parameters. Thenset the same P-, I- and D-values in all parameter sets.You can then search special parameters for a certaintemperature range which do not affect the remainingtemperature ranges.

Carry out an automatic optimization for all temperatureranges, if necessary.

If an error occurs one of the following error messages isdisplayed:

Error code Reason

F 10 The furnace does not reach the settemperature

F 30-32 Error of thermocouple or measuringcircuit

F 40 Thermocouple has reverse polarity (e.g.after replacement of thermocouple -change polarity)

F 50 Temperature or time entry incorrect(correct entry)

F 60-61 Controller system errorF 62 Ambient temperature too low

70CF 64-69 Controller system errorF 70 Furnace temperature has exceeded the

permissible Tmax valueF 90 Voltage failure (displayed after the

voltage has recovered)

Error messages can be reset by switching the mainsswitch off and on. Leave the equipment switched off forat least 5 seconds.Recirculation motors (if installed) remain switched on,even in case of an error. The heater is in any caseswitched off.

If the error message does not reappear within one minuteafter the system is switched on, the Controller is againready for operation. If the error message reappears, informNabertherm service.
