•
"modE"
Relay operating modes. Individual modes are described in the previous chapters: Single-
threshold and two-threshold control.
•
"unit"
unit of time for
“t on”
i
“toFF”
parameters. Can be set on one of two values:
"min"
minutes
"sec"
seconds
•
"AL"
this parameter defines the relay reaction when some critical situations occurs:
"noCH"
relay do not change his 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 allowable measurement range is exceeded.
If parameter
“modE”
is set to
“modb”
, the
“critical situation”
means communication
delay (when no data is received) longer than
“mbtO”
parameter (see description:
“rS”
menu).
If parameter
„AL” = „on”
, the relay will be turned on in the critical situations, even if his
parameter
“modE” = ”noAC”
.
•
"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.
•
"toFF"
turn off delay time, the relay is turned off with delay equal
“toFF”
if the input value exceeds
appropriate border value (defined with threshold and hysteresis), at least
“toFF”
time.
“toFF”
range 0 ÷ 99.9, defined with 0.1 sec. resolution. Unit of this parameter is set by
“unit”
parameter
