71 - 2 … 75 - 2
37
The pulse-echo measuring system can be equipped
with a current module.
The module has two current outputs.
Coordination
MODE 0 - 64
Each current output can be coordinated separately
to either channel (or difference).
Same procedure for current output 2, but with
respective modes, see above.

Programming example
Coordinate current output 1, channel 2 ....................
• select mode 0 - 64 in MODEFIELD
• program figure 2 in PARAMETER FIELD
• then store with STO-button
Output characteristic
MODE 0 - 65 and 0 - 66
The characteristic of the current output is fixed by
an initial and final point.
The factory preset defines a course of 4 … 20 mA
acc. to 0 … 100 %.
Within the total range of 0.00 … 20.00 mA each
current value can be programmed for a rising or
falling level.
The current-
∆
between initial and final value must
be min. 1 mA.
• select mode 0 - 65 in MODEFIELD
• program 16.00 mA in PARAMETER FIELD
• then store with STO-button
• select mode 0 - 66 in MODEFIELD
• program 00.00 mA in PARAMETER FIELD
• then store with STO-button
