Digital Inputs
About Digital Inputs
The digital inputs are used to provide the UltraTWIN with information on the
operational status and condition of pumps, valves, and other process control
devices. Based on the information supplied, by the inputs, the UltraTWIN,
will make intelligent decisions and modify its control regime to meet the
demand of the prevailing operational requirements.
The parameters used to program the Digital inputs are as follows:
Common Parameters P*300 to P3*06
Digital Input 1 P*372 to * 374 Digital Input 2 P*375 to * 377
Digital Input 3 P*378 to * 380 Digital Input 4 P*381 to * 383
Digital Input 5 P*384 to * 386 Digital Input 6 P*387 to * 389
Digital Input 7 P*390 to *392
Common Parameters Set-up
These parameters determine specific operational criteria for particular digital
input functions and are common to each digital input.
Input Type
The digital inputs can be either voltage source, where UltraTWIN will supply
the switching voltage, or voltage synch, where the switching voltage is
supplied by the input from the device, for full details see
Chapter 2
UltraTWIN Installation . Both voltage source and voltage synch. inputs can
be configured for N.O. or N.C. operation as determined by the digital input
Type P372, 375, 378, 381, 384, 387, 390 when set to 1= Input N.C. ,
UltraTWIN will recognise a closed condition, D.C. signal voltage present at
input, as a healthy condition, alternatively, an open condition, D.C. signal
voltage isn’t present at input, indicating a healthy condition, can be chosen
as a valid input by selecting 2=Input N.O .
Important Notice
In the following parameters, * denotes the point of measurement being
used (* = parameter selectable in Point 1 and/or in Point 2).
All menu options are the same for Point 1 and Point 2. Measurement points
can be “toggled” by pressing to change from point 1 to point 2 to
access parameters on each point.
