50
Example:
Setting a temperature of 50 C on the external programmer!
The value adjusted and set on the external programmer is displayed in
line 4 of the DIALOG-DISPLAY (LCD) for control purposes (Example:
ExtSet: 50.0 C).
After returning the LCD display to standard display by pressing escape
(„Setpoint“ - see page 37) this value is displayed in line 1
(Example: EPROG 50.00 C).
This EPROG input enables the use of different voltage and current
values as program parameters.
„L Value“ - Setting the LOW value:
1) Adjust and set the lowest desired value on the voltage or current
source resp. (Example A: 1 V).
2) Assign a lower temperature threshold value to this adjusted
voltage/current value by pressing the appropriate buttons on the
keypad of the programmable controller (Example A: 20 C ) and set
by pressing enter
.
„H Value“ - Setting the HIGH value:
1) Adjust and set the highest desired value on the voltage or current
source resp. (Example A: 10 V).
2) Assign an upper temperature threshold value to this adjusted
voltage/current value by pressing the appropriate buttons on the
keypad of the programmable controller
(Example A: 200 C) and set by pressing enter
.
Return to the standard display by pressing escape
.
Example B in the diagram serves to illustrate that the end point values
are freely selectable.
Example out of diagram A:
Adjusting the voltage source for an output of 7.6 V!
Line 4 of the DIALOG-DISPLAY (LCD) shows the externally set setpoint
value. The programmable controller calculates this value from the rise
angle of the two predecided end points (in example A: 7.6 V correspond
to an external setpoint temperature of 152.0 C ).
After returning the LCD display to standard display by pressing escape
, this value is displayed in line 1
(Example: EPROG 152.00 C).
Notice:
If this adjustment is not correctly performed at two different points, the setpoint setting will be
incorrect.
