User manual for - FLOW METER SPI-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.
“inPUt” menu
This menu contains options of pulse input configuration:
“PulSEL”
- flow factor (quantity of pulses per litre). This parameter can be set in range
0.00 - 9999.99 pulses/litre.
Value 0.00 is interpreted as 10 000.00
pulses/litre.
Proper settings of this parameter is essential to device's operation.
“FrEq”
- maximum permitted frequency of pulses delivered to the input. This parameter
is expressed in Hz. And can be set to one of all values showed in Tab.7.1
