Manual de instrucciones BENTRUP TC 405

[. . . ] An example is shown below : 15 This firing curve consists of the following segments: [°C] 1000 a. 1st dwell (120 min. ) (a) (b) 120 (c), 240 (d) 360 (e) 480 (f) [min] 600 d. cooling down (350°C/h) Fixed programs and personal programs Often used curves are already in series - saved as fixed programs in the controller. Anyway you are able to save 9 individual curves - personal programs - which let you consider your experience and special wishes. [. . . ] In this case enter the new values by pressing the keys (2) for all parameters and put in the desired values using keyboard (8). After finished save this programme as explained in section 1. Even after the firing process has been started you can change the firing curve. 18 Changing the curve during a firing start stop Example: While running the programme you want to change the 1st dwell temperature to 500°C. Interrupt the programme by pressing the “start/stop”-key (9). Now select the segment by pressing the corresponding key (2) and enter the new value with the numeric keyboard (8). After pressing “start/stop” (9) again the firing process will continue with the new value. When you change a segment that has already been finished the TC405 will start from the beginning. t m p1 0 0 5 start stop Locking the controller To prevent the TC405 from unauthorized use press the “key button” (5) for about 3 seconds. You will see the decimal point on the very left hand side of the display (6) indicating that the controller is locked. To unlock the TC405 press the key (5) for 3 seconds again until the indicator goes off. Further hints Firing course with only one dwell temperature You need a programme with only one dwell. 150°C/h until it reaches 1000°C followed by a dwell of 30 minutes.

In this case the kiln heats up to the first firing temperature, dwelling for the given time (t1) and then cooling down to the second temperature dwelling again (applications like crystal glaze or simple glass fusing or slumping) Reaction on a power breakdown In case of a power breakdown the firing process is interrupted. After the power comes up again the controller will continue exactly from the point at which it was interrupted. A power failure longer than 30 minutes causes the automatic termination of the programme because theoutcome of the firing is likely to be unsatisfactory Maximum values The maximum valid programme values are listed below: programme delay (t0) 0 min to 9999 min 1. heat up rate 2°C/h to 999°C/h* 0 min to 9999 min 2. (tmp2) 20°C to 1320 °C** cooling (°C/h) 2 °C/h to 999°C/h* *the value of 999°C/h sets the controller to the maximum speed heating or cooling respectively. ** controller is adjusted to the maximum kiln temperature Displaying the power consumption The TC405 gives you the possibility to call up the power consumption of the last firing. To use this feature you have to programme the kilns power once. Refer to the section "Setting the parameters". Press key "kwh" to read the power consumption since the last firing has been started. The display switches back after 2 seconds. 20 event Option: Linking Programmes This option of your controller is included on request only. Ask you kiln supplier if you like to use this feature. [. . . ] All heating cycles of the kiln will be summarized allowing the lifetime of the heating elements to be checked. For resetting to zero additional code required maximum temperature reached on last firing. This value is useful if a problem is encountered during the firing because it shows at which temperature it occurred. Automatic reset after each power up / restarting the controller or loading a programme. [. . . ]
