Setting the setpoint: external setpoint
For external setpoint setting you state a scaling.
A range of flow rate corresponding to the standard signal (4 - 20 mA, 0 - 10 V) is
set here, i.e. the flow rate is entered at 4 mA or 0 V (lower limit) and at 20 mA or
10 V (upper limit).
Example:
lower limit ( EXLO) 0 l/min 4 mA
upper limit ( EXHI) 180 l/min 20 mA
Settings are possible between 0 and 655.2. If it is attempted to set a higher value,
the display will jump automatically to 0 and a value must be entered within the
range. The decimal point cannot be set at the first (left-hand) position. The unit
corresponds to the value set in the menu item UNIT.
(factory setting: EXLO=0.00; EXHI=180.00).
If the value for EXHI was selected lower than that for EXLO or
equal to it, the texts MODE and ERR 9 appear flashing
alternately on the text display.
In this case the newly set values are not stored!
