You can check the values of a firing curve at anytime
even during programme run. If you want to change a
value you have to stop the firing by pressing the key
(20).
For instance to check the heat up ramp press key (6).
Display (14) reads the current value for the heat up
speed. The unit of the value (in this example degree
centrigrade per hour) is shown in (13). The correspon-
ding segment (b) of the firing curve (15) lights up.
To change this value simply enter a new value by
using the keypad (19). If you enter a value that is
outside the allowed range the controller rejects by
showing „- - - -“. If this is the case simply enter the
correct value.
For instance to check the final temperature press key
(3). As described before, the current value is shown in
display (14) and the corresponding section (d) of the
firing curve (15) lights up.
To change this value proceed as described before.
All values of the firing curve can be checked and - if
required - changed as described. The sequence of
checking or changing is free. Only keep in mind always
stop a firing if you intend to change a programme.
On delays of more than 15 seconds the display (14)
returns to the current programme setpoint. Select the
segment to change again if you wish.
On most firings the customer wants to heat up the kiln
as fast as possible from 1st dwell temperature to final
temperature. This is done by entering the value „SKIP“
on segment (d).
Press key (18) to select segment (d). Now press the
digit key „9“ on the keypad (19) 4 times. TC505
shows „SKIP“ on display (14) as depicted on the left.
This option can be used on all ramps (i.e. segments
(b), (d) and (f).
