Save The Parameter File:
After having set up the 4-20 mA inputs (hardware, wiring, and transducer/transmitter as
well as alarms), the parameter file should be uploaded from the device to the PC and
then saved. In this way the settings will not be modified again if the parameters are
reloaded to the device.
Binary
If the multi-inputs are configured to "Binary", they become available as binary inputs
which means a switch function input.Input Function Selection
Digital input alarms can be configured with a possibility to select when the alarms are to
be activated. The possible selections of the input function are normally open or
normally closed.
The drawing below illustrates a digital input used as an alarm input.
1. Digital input alarm configured to NC, normally closed:
This will initiate an alarm when the signal on the digital input disappears (contact
opens).
2. Digital input alarm configured to NO, normally open:
This will initiate an alarm when the signal on the digital input appears (contact closes).
NOTE: The relay output function can be selected to be ND
(Normally De-energized), NE (Normally Energized), Limit or Horn.
