Programming Using Local adjustment
4.5
Z: Moves to the SAVE function.
S: Decreases the control output until the magnetic tool is removed or the lower output
limit is reached.
Save (SAVE)
Z: Moves to ESCAPE of the operation menu.
S: Saves the setpoint and Manipulated Variable in the transmitter EEPROM, for use as
power on SP and MV.
Escape (ESC)
Z: Moves to the AUTO/ MANUAL function.
S: Escapes to the MAIN menu.
TUNING [TUNE]
This adjustment option is applicable to the LD301 configured in the Controller mode. It allows the
control loop to be tuned, acting on the Proportional, Integral and Derivative terms, and also to alter the
PID mode. The implemented algorithm is a PID type, with the following characteristics:
The proportional action is given by the Proportional Gain and not by the proportional band. Range:
0 - 100.
Integral action is expressed in minutes per repetition. Range: 0 - 999 min/rep.
The derivative constant is obtained in seconds. Range 0 - 999 seconds.
It is possible to cancel the Integral and Derivative actions by adjusting Tr and Td, respectively, to 0.
Figure 4.4 shows branch TUNE with the available options.
