Self-Optimizing (Pid Action) Of Control Circuit - M&C 70304G Instruction Manual

15.2 SELF-OPTIMIZING (PID ACTION) OF CONTROL CIRCUIT

The controller type 70304G includes the option of self-optimizing. For the initial operation of all M&C
components, this is necessary.

Before self-optimizing firstly the ramp function has to be deactivated (Fnct = 0) and the parameter for
the limit comparator has to be changed (Lfun = 6). See also chapter 13.
The self-optimizing function can be activated as follows:
After cable connection (Figure 3), switch on the supply.
•
When the actual value (top display, red indicator)
•
reaches the setpoint value (bottom display, green indicator), press
longer than 2 seconds. The word "tUnE" now flashes in the setpoint value display and the self-
optimizing function is activated.
Self-optimization has finished when the display changes to the standard display. The time of self-
•
optimizing depends on the control circuit.
To cancel the self-optimization, press the keys
•
After self-optimization reactivate the ramp function (Fnct = 1) and reset the parameter for the limit com-
parator (Lfun = 2).

For self-optimizing of the control circuit, the heating of the respec-
tive M&C component must be reconnected to the appropriate con-
troller terminals (see Figure 3).
Before connecting the heating, isolate the unit from the power
supply!
