Operating Conditions
The process value is output when the MAXREQ or MINREQ signal is ON at the
time the output is tested in test mode.
Multiple input signals must not turn ON. If multiple input signals turn ON or a
single signal input is combined with another signal input, all output data will be
turned OFF.
When a REQ signal is input from a Programmable Controller to the K3NP in
RUN or test mode, the K3NP outputs a DATA VALID (DSV) signal. In other cases,
the K3NP has All Signals OFF (H) output.
Refer to the following for the timing of each signal.
Pulse of 20- to 50-ms duration
All data "H"
Approx. 30 ms
The REQ signal must be kept ON as shown below if the K3NP has continuous
data output.

The polarity of the data must be checked with a POLARITY signal. The polarity is
positive when the POLARITY signal is OFF and negative when the POLARITY
signal is ON.
The K3NP in test mode has test data output regardless of the type of REQ signal.
The RUN signal is turned ON in RUN or test mode. The RUN signal is, however,
turned OFF when an error other than overflow results.
Do not input multiple signals, otherwise all output data will be turned OFF.
