ADJUST PID PARAMETERS
In order to determinate the setup values for PID regulation, we recommend to use the Ziegler-Nichols open loop method
Proceed as following:
- Connect a recorder to the analogic measurement output or write the reading measurement values for then to draw the graph f(time)
- Switch on the PID regulation in MANUAL mode
- Reach to and keep close the measurement value to the set point, adjusting the PID output
- Apply on ΔCde a step of 10 % (for instance) on the analogic output (Cde).
Example: if the value is 30,00 %, apply 40,00 %
- Note on the graph the corresponding timing.
- Determinate on this graph both t ant T:
t = delay of response
T = Time corresponding to the same variation in % of measurement (Δm) and the analogic output (ΔCde), Δm = ΔCde.
This value may be found out on the slope.
- Modify the PID parameters as following:
REGUL PID Output mA Oxygen Please see page 14
This operating mode allows a PID regulation with
an analogic output 0/20 or 4/20 mA
REGUL ON/OFF To switch ON or OFF the regulation mode
REGUL AUTO/MANU MANU=MANUAL to be able to check the relays output
