Operation / set-up
90
Function Activation of the input triggers the set function. The digital inputs are high-
active, i.e. the selected effect is achieved by activation with +12 to +30 VDC.
See also Section 4 "Wiring".
!
Depending on the selected function, the device's user interface adapts itself,
so that each time only parameters that are required for safe device functioning
have to be checked/set.
The following functions are available. These functions are described in detail in
the following sections.
"On/off event": for recording flank changes, i.e. in order to save the current
time at which this digital input has been activated or deactivated.
"Control input": for remote control of certain device functions that are
activated via binary signals. Please refer to the "Effect of the control input"
section for information on the possible functions.
"Impulse counter": for counting and adding quantity-proportional pulses.
"Operational time": for acquiring run times. The entire run time is cumulated,
saved in cycles that can be set and reset. See also Section 5.7.3 "Signal
analysis".
Example: If the daily run time of a pump is to be saved, activate "Operational
time" here and "Daily analysis" under "Signal analysis".
"Event+operation time": combination of the "Event" and "Operational time"
functions described above. With this, you can also acquire the on-time and off-
time as well as the cumulated run time.
"Quantity from time": The "quantity from time" calculation is already integrated
in the device, i.e. the delivery volume can be determined directly in relation to
time without the use of a flow sensor.
