Example out of diagram A:

• Adjusting the voltage source for an output of 7.6 V!

The instrument 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 VFD display to standard display, this value is
displayed in line 2 (Example: SP 152.00

°C).


Notice:

If this adjustment is not correctly performed at two different points, the setpoint setting
will be incorrect.

Important:
The usable temperature range between > LVAL < and > UVAL < is limited to the
configured working temperature range of the circulator resp. of the unit combination
(working temperature range see technical specifications)

9.9.3.
