User manual for - FLOW METER SPP-N118
“t on”
- turn on delay time, the relay is turned on with delay equal
“t on”
if
the input value
exceeds appropriate
border value
(defined with
threshold
and
hysteresis
), at
least
“t on”
time.
“t on”
range 0 ÷ 99.9, defined with 0.1 sec. resolution. Unit of
this parameter is set by
“unit”
parameter.
“t oFF”
- turn off delay time, the relay is turned off with delay equal
“t oFF”
if
the input value
exceeds appropriate
border value
(defined with
threshold
and
hysteresis
), at
least
“t oFF”
time.
“t oFF”
range 0 ÷ 99.9, defined with 0.1 sec. resolution. Unit of
this parameter is set by
“unit”
parameter.
If time when the input signal exceeds some border value is shorter than
“t on”
or
“t oFF”
time, the relay do not change its state
(see paragraph:
CONTROL OF
THE RELAY OUTPUTS
).
“unit”
- unit of time for
“t on”
i
“t oFF”
parameters. Can be set on one of two values:
“min”
- minutes,
“SEC”
- seconds.
“ALArmS”
- this parameter defines the relay reaction when some critical situations
occurs:
“noCHAn”
- relay do not change its state,
“on”
- relay will be turned on,
“oFF”
- relay will be turned off.
If parameter
“modE”
is set to
“on”
,
“oFF”
,
“in”
or
“Out”
the “critical situation”
means that
permissible input frequency
is exceeded.
If parameter
“modE”
is set to
“modbuS”
, the “critical situation” means
communication delay (when no data is received) longer than
“mbtimE”
parameter
(see description:
“rS-485” menu
).
7.3.2.
“FLouu” menu
This menu presets the measurement input and allows configuration of current flow rate
displaying mode:
“I tyPE“
- type of the input / sensor. This parameter can be set to values:
”
0-20
”,
“
4-20
”
- current inputs of 0÷20mA or 4÷20mA of measurement range
respectively. Displayed values are defined by parameters
“Lo CAL”
,
”Hi CAL”
(or by user defined characteristic points) and
parameter
”Point”
.
“I CHAr“
-
this option sets type of the conversion characteristic.
This preset is essential when
meter cooperates with flow sensor, which changes it's output current accordingly to
characteristic other than linear. It can be set to:
