Operator control
MANUAL/AUTO key
Switching over the MANUAL and AUTOMATIC modes.
The AUTOMATIC mode is indicated by an LED in the operator
control.
Switch-over to the next process variable
SP:
Set-point
PV:
Actual value of controlled variable PV1 (or of the Ratio)
CO:
Manipulated variable
(Ch and Cc for 3-point PWM signals)
F:
Flow rate (actual value of the Input PV1 for ratio control)

•
Reducing the value of the manipulated variable (in MANUAL
mode), i.e. reducing the voltage or current (in the case of
standard signals) or the pulse width in the case of PWM signals
•
Relay 2 on (motor „Reverse“) in the case of 3-step signals
without external feedback
•
Modifying a numeric value
•
Increasing the value of the manipulated variable (in MANUAL
mode), i.e. increasing the voltage or current (in the case of
standard signals) or the pulse width in the case of PWM
signals
