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 26) 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.
