Setting the hysteresis
The hysteresis indicates by how much the setpoint
and the actual value must differ for the position con-
troller to correct the actual position by moving the
actuator.
If the position controller reacts too sensitive or too
slow, the hysteresis potentiometer can be used to
set the hysteresis within the range of 0.5 ... 10% of
the input limit.
Completing the programming
To complete the programming and switch the posi-
tion controller to automatic mode, set sliding switch
Auto/Manu to the position ON = automatic mode.
This position is then regulated by means of the set-
point applied.
6.2.8 Fault message output
The fault message output integrated into the position controller is a potential-
free switching contact that opens when an error occurs. This allows the cor-
rect function of the actuator to be monitored.
Current-carrying capacity:
−
max. 125V AC, 10VA (resistive), or
−
125V DC, 10W (resistive)
The contact opens if the following fault events occur:
−
mains voltage failure
−
controller manual mode is active
−
broken-wire detection for setpoint signal (only with the setting 4 D 20mA
and/or 2 D 10V)
−
current setpoint value < 2mA
−
voltage setpoint value < 1V
