Switching direction
Limit value 1; Limit value 2
Switch-on delay ∆t on
Switch-off delay ∆t off
If the limit is exceeded for longer than the "Delay time - limit values" an error message is given, which
must be acknowledged, and the alarm relay circuit is broken. If "Controller" is also set to "off" the control
process stops.
Servomotor
The operating range is defined by the total resistance range of the feedback potentiometer. The maximum
limit of the range actually used is set by defining the control range.
CAUTION
• Activation of the servomotor must be carried out with the same meticulous care as taken
when calibrating a measuring probe.
• To ensure correct operation, the activation time of the actuator used should not be less
than 25 seconds for the control range from 0...100 %!
