unit of time for “t on” i “toFF” parameters. The unit be set to one of two values:
"unit"
"min"
minutes
"SEC"
seconds
this parameter defines the relay reaction when some critical situations occurs:
If parameter “modE” is set to “on” , “oFF”, “in” or “Out” the “critical situation” means that the
allowable measurement range is exceeded.
If parameter "modE" is set to "modb", the "critical situation" means the communication
delay (when no data is received) is longer than "mbtO" parameter (see description: "rS"
menu).
"AL"
"noCH"
relay do not change state,
"on"
relay will be turned on,
"oFF"
relay will be turned off.
If option
“noCH”
is selected for
“AL”
parameter, behaviour of the relay may depend on
“FiLt”
parameter in some cases. If “FiLt” is set to big value and the input signal drops, result value of
the measure will change slow, causes of turning on or off relay due to thresholds values. The
critical situation is slowly detected, so it is impossible to predict the relay state in that
situations.
If parameter „AL” = „on” , the relay will be turned even if his parameter “modE” = ”noAC” .
Acoustic signal (turned on by e.g. relay ) can be turned off by pressing of any button
"r1”
if this parameter is set to “on” , activation of relay R1 causes by acoustic signal
"AL” if this parameter is set to “on” , any critical situation causes by acoustic signal
"r3" if this parameter is set to “on” , activation of relay R3 causes by acoustic signal
"r2"
if this parameter is set to “on” , activation of relay R2 causes by acoustic signal
"r4"
if this parameter is set to “on” , activation of relay R4 causes by acoustic signal
This menu contains options connected with acoustic signal :
