rel
: Select relay number
ch/mode: Set relay assignment
Each relay can be assigned to a measuring channel "ch1" to "ch4"
and to various switching modes.
Switching modes:
press: Relay switches according to switch-on and switch-off pressure
err / !err: Relay switches in case of a sensor failure
ur / !ur: Relay switches in case of pressure underrange
or / !or: Relay switches in case of pressure overrange
Setting "on" becomes effective as soon as controlling is started.
on/off : Adjust switch-on pressure T and switch-off pressure F
The switch-points are adjustable over the whole measuring range.
If switch-points for on and off are set too close this may result in
flickering and damage of the relay!
