12.4.3 Limit Value Responses
Relay assignment
For reporting alarms in the event of a limit value
being exceeded alarm relay cables or new V6
relay adapters are used. These relays can be
configured individually - as total alarm or sepa-
rately as maximum / minimum alarm - or they
can have individual limit values assigned to
them.
If disturbances need to be selectively detected
and evaluated, one can simply specify the limit
values in the wizard menu
and assign these to individual relays; (see Man-
ual 6.10.8). It is also possible to have a number of limit values assigned to the
same relay. If the relay adapter is connected the corresponding relay will auto-
matically be set to variant 2 (Assigned internally). If not, it must be configured
to this variant later.
Or alternatively in the programming menu
tions
Action - Max
To activate relay "xx" in the event of overshooting limit value maximum :
tion, maximum :
To activate relay "yy" in the event of undershooting limit value minimum :
tion, maximum :
To clear relay assignment press
The relays can be configured in menu
To set port 20, socket A2
a normally open semiconductor relay
to variant 2 (relay assigned internally)
Controlling a measuring operation
The exceeding of a limit value can be used not only for reporting an alarm but
also for controlling a measuring operation (see Manual 6.6.3). Commands can
be assigned to a limit value by means of the functions :
Action, maximum and Action, minimum
Start meas. operation at limit value, max:
Stop meas. operation at limit value, min:
Manual inquiry at limit value, maximum :
Zero-set timer 0.1s at limit value, max:
Execute macro 5...9 at limit value, max:
