4.3 Switchpoints
The VD6 can be configured as two- or three-state-controller as described in
chapter
5.2 .
Switching Mode "2P" (2-state-control)
The relay outputs SP1 and SP2 are each adjusted by a setpoint and a related
hysteresis (H1 and H2). Both switching outputs work independently of each
other.
The hysteresis is set symmetrically around the setpoint. When the setpoint is
changed the related hysteresis is automatically adjusted by means of a percent-
age relation. Afterwards the hysteresis can be manually adjusted (value is
checked for plausibility with regard to the setpoint).
Example:
setpoint 1 = 10mbar / H1=1mbar (10% from setpoint)
Switching output 1 is deactivated at 9mbar, activated at 11mbar.
Change:
setpoint 1 = 1.0mbar / H1=0.1mbar (automatically !).
Switching output 1 is deactivated at 0.9mbar, activated at 1.1mbar.
