4.4 Menu RELAY - Switching Outputs
In the RELAY menu you can assign the switching outputs and set relay
parameters.
rel
: Select relay number
- - > : Set relay assignment
Each relay can alternatively be assigned to a measuring channel
("ch1" to "ch4") or to a function key ("F1" or "F2") or it can be directly
set to state "on" or "off".
When a relay is assigned to function key F1 or F2 it can be manually
switched on and off by that key.
Setting "on" becomes effective as soon as controlling is started.
set : Adjust setpoint
The setpoint is adjustable over the whole measuring range. It is
mandatory, however, to consider a minimum distance of the setpoint
from the range limits of at least the magnitude of the chosen hyste-
resis.
hyst : Set hysteresis
The hysteresis can be set up to 90% of the setpoint.
Too small values for the hysteresis may result in a flickering relay!
