Digital Inputs
About Digital Inputs
The digital inputs are used to provide the Quantum
3
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 Quantum
3
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 P300
to
P306
Digital Input 1 P372
to
374
Digital Input 2 P375
to
377
Digital Input 3 P378
to
380
Digital Input 4 P381
to
383
Digital Input 5 P384
to
386
Digital Input 6 P387
to
389
Digital Input 7 P390 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 Quantum
3
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
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 w
hen set to
1= Input N.C.
, Quantum
3
will recognises
a

condition, D.C.
signal
voltage
present
at input, as a healthy
condition, alternatively, an
open
condition, D.C.
signal
voltage
not present
at input, indicating a healthy condition, can be chosen as a valid input by
selecting
2=Input N.O
