4 Functions and operation
You can operate and program the transmitter by using the q, d
and i buttons in conjunction with the LC display and the blink cy-
cles of the “Power” and “Status” LEDs, which have already been
described in Chapter 3 “Displays and controls”.
In use, three operating states can be distinguished:
- Operating level (normal operation)
- Parameter level (programming mode)
- Configuration level (programming mode)
Operating level
The transmitter is at the operating level 2 seconds after power-on,
or after leaving the parameter or configuration level.
Parameter level
From the operating level, you can access the parameter level by
pressing the
q button (for at least 2 seconds). The following func-
tions can be programmed at this level:
- Limit value for limit comparator 1 AL1
- Limit value for limit comparator 2 AL2
- Fine calibration (zero point - 0%) OUTL
- Fine calibration (full scale - 100%) OUTH
- Teach-in OFFS
The parameter level is exited (quit)
- after editing the “Teach-in” parameter,
- if no button has been pressed for at least 20 seconds,
- or by pressing the button combination q + d.
The individual parameters can be altered, one after another. You
can step from one parameter to the next by pressing the
q button.
