english

If the value for EXHI was selected lower than that for EXLO or equal
to it, the texts MODE and ERR9 appear flashing alternately on the
text display.

In this case the newly set values are not stored!

Setting the setpoint: external setpoint

For external setpoint setting you state a scaling. The temperature range
corresponding to the standard signal (4 - 20 mA, 0 - 10 V) must be set, i.e. the
temperature is entered at 4 mA or 0 V (lower limit) and at 20 mA or 10 V (upper
limit).

Settings are possible within -50 °C and 150 °C or -58 °F and 302 °F . If it is
attempted to set a value outside this range, the display will jump automatically to 0
and a value must be entered within the range. The unit corresponds to the value
set in the menu item UNIT (factory setting: EXLO=0.0 °C; EXHI=100.0 °C).

Example:

Lower limit (

EXLO)

20 °C

4 mA

Upper limit (

EXHI)

60 °C

20 mA

For example, a standard signal of 12 mA corresponds to a setpoint of 40 °C.
