User manual - FLOW METER SPI-638
•
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.
“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.
“bEEP” menu
This menu contains options connected with acoustic signal :
"
AL
”
- if this parameter is set to “
on
”, any critical situation causes by acoustic signal
"
r1”
- if this parameter is set to “
on
”, activation of relay
R1
causes by acoustic signal
"
r2
"
- if this parameter is set to “
on
”, activation of relay
R2
causes by acoustic signal
"
r3
"
- if this parameter is set to “
on
”, activation of relay
R3
causes by acoustic signal
"
r4
"
- if this parameter is set to “
on
”, activation of relay
R4
causes by acoustic signal
Acoustic signal (turned on by e.g. relay ) can be turned off by pressing of any
button
