Control Action
Set the required control action:
Rev.
– Reverse acting – see Fig. 1.2.
Direct – Direct acting – see Fig. 1.3.
Proportional Band
Set the required proportional band between 0.1 and 999.9% in 0.1% increments.
Integral Action Time
Set the integral action time between 1 and 7200 seconds in 1 second increments.
Set to 0 to disable integral action time.
Derivative Action Time
Set the derivative action time between 0.1 and 999.9 seconds in 0.1 second increments.
Set to 0 to disable derivative action time.
Note. Derivative control in pH applications could cause instability. It is therefore
recommended that this is set to 0 in pH applications.
Output Type
Set the required output type:
Time
– Time proportioning (relay 1)
Analog – Analog output (analog output 1)
Pulse
– Pulse frequency (relay 1)
