6.3. CONTROL OF THE RELAY OUTPUTS
The control of the object (measured signal) is done due to gross or nett value
(depending on
“SourCE”
parameter ), and is realized via relay outputs. Front panel LEDs
named „
R
” indicates the state of particular relay output.
Modes of the control can be changed depend on the values of parameters “SourCE” ,
“SEt P” , “SEt P2”, “HYSt” , “modE” , “t on” , “t oFF” , “unit” and “ALArmS”. Depend on
“modE” parameter, relays can be not used or controlled over one or two thresholds values.
If one threshold is used ( Figure 6.2 ) the relay can be turned on ( “modE” = ”on” ) or off
(
“modE”
=
”oFF”
) when the input signal value is contained in
zone A.
If two thresholds are
used (
Figure 6.3
) the relay will be turned on when value of input signal is contained in
zone
A ( “modE” = ”in” ) or zone B ( “modE” = ”out” ) and turned off if the signal is contained in
the second one.
