Other Number And Status Inputs; Warning Input Active - Honeywell EK280 Applications Manual

EK280

5 Other number and status inputs

Inputs 2 to 6 (terminals DE2 to DE6) can be programmed with status or pulse inputs.
If input 2 is being used as a hedge for input 1 volume detection ( chapter 4), it is no longer available here.
Each input can be programmed as described in the following  sub-chapters with the following functions:
−

Warning input active

− Warning input inactive
− Information input active
− Information input inactive
− Time-synchronous input
− Pulse comparison
− Metering pulse (not suitable for calibration)
Whereby:
− active
− inactive
− Notice input
− Warning input
− Time-synchronous
− Pulse comparison
− Meter input
5.1 Warning input active
Each of inputs 2 to 6 (terminals DE2 to DE6) can be programmed as active warning inputs. This means:
If the "+" and "-" poles of the electrical inputs are connected electrically,
− the message "8" is entered in the momentary status for the relevant input,
− the message "8" is entered in the status register for the relevant input.
− "W" flashes in the display.
Application Manual
The signal is valid, if the terminal poles are conductively connected.
The signal is valid, if the terminal poles are not conductively connected
(open).
A valid signal input generates an information message in the momentary
status for the relevant input.
A valid signal input generates a warning message in the momentary
status and status register for the relevant input.
With a valid input signal the EK280 clock can be synchronized (set) to
the full hour.
A user-defined variation between two pulse generators generates a
warning message in the momentary status and status register.
( chapter 4.5).
Usage as an additional meter input for a non-calibrated metering period.
However, the values can be recorded in a flexible archive.
