“t unit”
- the unit of relay thresholds and hysteresis when relay is controlled due to total flow
counter result. It can be set to:
“lit.”
- Litres
“m 3”
- cubic meters
Parameters ”
t PrEc
” and ”
t unit
” are available only if total flow counter is used to
control relay output (
“SourCE”
=
”
tot
”). When current flow rate is used to control
relays, the unit and precision of the thresholds and hysteresis are defined by
parameters
“F unit”
,
“Ftunit”
and
“F PrEc”
of menu
”Flouu”
. When relay (other
than
R1
) is controlled in relation to „
SEt P
” threshold of relay
R1
(
“SourCE”
=
”
PrE r1
”), the unit and precision of the thresholds and hysteresis of
relay (other than
R1
) are defined by parameters
„b unit”
and
„b PrEC”
parameters available in submenu of relay
R1
.
“modE”
- relay operation mode:
“noACt”
- the relay is not active (permanent turned off)
“on”
- one threshold mode, the relay is turned
ON
when input signal exceeds
SEt P
+
HYSt
value
,
and is turned off back when the input signal became
lower than
SEt P - HYSt
,
“oFF”
- one threshold mode, the relay is turned
OFF
when input signal exceeds
SEt P
+
HYSt
value
,
and is turned on back when the input signal became
lower than
SEt P - HYSt
,
“in”
- two threshold mode, the relay is turned
ON
when the input signal is
bigger than “
lower threshold
+
HYSt
”
and lower than “
bigger
threshold
-
HYSt
”, and turned off when the input signal is contained in
the second zone. The
bigger threshold
means bigger one of
“SEt P”
and
“SEt P2”
thresholds, the
lower threshold
” means lower one of
“SEt P”
and
“SEt P2”
thresholds.
“Out”
- two threshold mode, relay is turned
OFF
when the input value is bigger
than “
bigger threshold
+
HYSt
”
and lower than “
lower
threshold
–
HYSt
”, and turned on when the input signal is contained in the second
zone. The
bigger threshold
means bigger one of
“SEt P”
and
“SEt P2”
thresholds, the
lower threshold
means lower one of
“SEt P”
and
“SEt P2”
thresholds.
“modbuS”
- the relay is controlled via RS-485 interface, independently on the
input signal.
•
LEDs light when relays are closed
, independently of relays' mode.
•
When power supply fail, unit do not store relays state selected by RS-485
interface.
